Thank you, Rodny, and thank you , everyone, for participating in today's call. 2020 was a milestone year for Tecnoglass on many different fronts. On the operational side, during 2020, we further advanced our leadership position in the architectural glass industry to produce results at record levels across many metrics. In early 2020, we announced that we had completed the implementation of several important high-return investments in automation and capacity to further strengthen our vertically integrated operations. These enhancements allowed us to produce record full-year operating cash flow, in addition to record gross profit and adjusted EBITDA, both on a dollar basis and as a percentage of sales. Building on the momentum from our structural enhancements, we navigated successfully through pandemic-related challenges to source and win new businesses, which allowed us to end the year with our backlog up slightly on a year-over-year basis to a comfortable position of $545 million.
These exceptional results reflect the resilience and dedication of our team. We ended the year on a positive note as we capitalized on the strong residential macro tailwinds and recovering commercial end market conditions to achieve our second straight quarter of growth in the U.S. Geographic diversification is an important part of our strategy. We continue to expand and diversify operations within attractive U.S. markets as we aim to capture additional market share, mainly in the rapidly growing Southeast region. As a result of our focus on maximizing our potential in the U.S., the country now represents 91% of full -year 2020 revenues, compared to 85% in 2019. Most importantly, our focus on the single-family residential end market has been, and will remain, a significant driver of growth.
At the end of 2020, single -family represented nearly 21% of our sales, compared to 18% in 2019, and only 3% just four years ago when we entered that business in 2017. Our recently introduced product line, called Multimax, includes models for promotion to home builders, which is opening additional growth channels with those on-tap large customers. During the year, we also made significant progress by enhancing our capital structure to create additional value for our shareholders. Starting in the first quarter of 2020, we amended and simplified our dividend to a purely cash-only payment and eliminated the option to receive dividends in the stock.
Our success with managing our working capital is translating into a step change in cash generation, with our operating cash flow representing over 70% of adjusted EBITDA in 2020. Our outstanding cash flow allowed us to improve our leverage profile to a very conservative 1.6 x at December 31st, a level not seen since 2016. In November, our cash generation and record of success as a U.S.-focused company were validated by an extremely favorable recapitalization of our debt. This was funded by a consortium of mostly U.S. and European-based lenders on terms that were comparable to, or better than, many publicly traded U.S. companies of similar size. In further commitment to our U.S. shareholder base, we recently completed our planned delisting from the Colombian Stock Exchange. Tecnoglass shares are now exclusively listed on Nasdaq, which we believe better aligns with our evolution as a U.S.-focused company.
We remain committed to returning a portion of capital to shareholders while delivering strong returns on our accretive investments to drive improved profitability and cash flow. In summary, I'm extremely encouraged by our performance during 2020. We were thrilled to exit the year with a much stronger and leaner company, underpinned by a significantly improved capital position to further extend our leadership position in the industry. We will continue to leverage Tecnoglass' structural competitive advantages to maintain industry-leading margins while capturing additional market share in the U.S. We are well-situated to achieve another year of stellar financial performance and returns for our shareholders in 2021. I will now turn the call over to Chris to provide additional details on our backlog.
Thank you, José Manuel. Moving to our backlog on slide five. Fourth quarter results were encouraging, and we were pleased to return to growth in total revenues to close out an extraordinary year. The resiliency of our business is evident in our backlog, which rose approximately 2% sequentially to $545 million, or 1.5 x our LTM revenue, with a good mix of project wins in some of our key U.S. markets. The overall quote and bidding environment was strong throughout the fourth quarter and remains very active as we move into the new year. We ended the quarter with a solid multi-year project pipeline, and we are actively pursuing new projects and partnerships to advance our growth in the U.S.
The most recent data from IBISWorld indicates that the glass and glazing contractors industry is expected to rebound at an annualized rate of 4%-5% over the next five years to 2025, led by residential. ABI projects inquiries and new design contracts have continued to recover since the bottom in April. The persisting strength in most of our sectors and regions gives us the confidence that we are in the right markets with the right products at the right time. Based on both our new and long-standing partnerships, innovative product lines, structural competitive advantages, and attractive geographic focus, we believe we can grow above the market in the coming quarters. As we mentioned last quarter, our backlog includes all product types and is approximately one-third non-residential, while roughly two-thirds is related to medium and high-rise multifamily projects, as well as single -family in production.
However, single -family is underrepresented in our backlog due to the shorter-term nature of the orders, and this will continue to influence the relationship between backlog and forward revenue as we further increase the mix of our revenue towards single -family housing-related projects. Looking to 2021, we are most excited about the significant opportunities we have to further penetrate the single -family residential market, where we see the most attractive growth opportunities in the near term. Turning to an overview of this business on slide six. Single -family macroeconomic tailwinds continue to support robust end -market demand in U.S. housing starts. Existing home sales, low supplies, urbanization trends, and low interest rates are providing us with opportunities to continue expanding our addressable markets.
Our rapid expansion into single -family residential continued into the fourth quarter, with revenues expanding more than 50% year-over-year in the quarter and representing nearly 21% of our full -year 2020 U.S. revenues, compared to 18% in 2019. We have worked hard to expand the reach of our single -family products beyond South Florida and into other markets in Central Florida and the Florida Panhandle. As a result, we experienced single-family revenue growth of 17% sequentially since Q3 2020. As we deepen our presence in single -family, we are focused on penetrating the southeast U.S. This includes planned efforts to expand our networks of dealers to broaden the reach of our Prestige and Elite product lines, in addition to our top-tier Multimax product line, which is mainly targeted for large-scale production builders and lower impact-resistant thresholds.
In fact, within the year, we expect to widen our dealer network for Multimax into attractive areas of Georgia, Louisiana, Texas, and South Carolina. As a reminder, our increasing the facility product mix provides us with greater manufacturing revenue, which positively impacts our margins. This business also strengthens our cash flow, given our single-family projects carry a shorter cash cycle and no retainage. Overall, our strong single-family performance in 2020 was augmented by winning new customers, creating new partnerships, entering new markets, and maintaining our commitment to innovation. We are dedicated to excellence and are excited to drive further improvement across our business in the coming quarters. I will now turn the call over to Santiago to discuss our financial results and outlook.
Thank you, Christian. During 2020, we reaped significant benefits from high -return investments in our facilities, leveraged our remarkable cash flow to strengthen our capital structure, expanded our business into new geographies, and captured additional market share in the U.S. Our 2020 results reflect these collective efforts and allowed us to drive record gross profit and adjusted EBITDA on both a dollar basis and as a percentage of sales, all while retaining our entire workforce throughout the COVID-19 pandemic. Our achievements to date underscore the resilience of our company and our people. Turning to the drivers of revenue on slide number eight. In the fourth quarter, outperformance in the U.S. drove growth in that market for the second straight quarter, leading to a return to growth in total revenues for the quarter.
Our strong performance in the U.S. has been the primary driver of our results and helped to offset delayed activity at many customer job sites in Colombia and other Latin American markets since the onset of the pandemic. Our Latin American markets remain in the early stages of recovery. However, we were encouraged to see Colombia sales up 80% sequentially since the third quarter of 2020. The U.S. continued to mark an increasing mix of our business in 2020, representing approximately 91% of our total full-year revenues, compared to 85% in 2019. Growth in our single-family residential business was approximately 8% for the full year 2020, but ramped up significantly toward the end of the year, with fourth quarter-over-quarter growth of more than 50%.
While growth in the single-family residential segment continues to outpace the rest of our business, we were pleased to see recovering conditions continue in all of our end markets we serve. Looking at the drivers of adjusted EBITDA on slide number nine. Adjusted EBITDA for the fourth quarter of 2020 increased 19.3% to $25.7 million, representing an adjusted EBITDA margin of 25.1%. Adjusted EBITDA for the full year increased 6% year-over-year to a record $97.8 million, representing a margin of 26.1%. Fourth quarter gross profit increased 25.8% to $36.9 million, representing a 36.1% gross margin. This is compared to a gross profit of $29.3 million in the prior year quarter, representing a gross margin of 28.9%. The prior year's quarter had an unusually high mix of installation revenue.
The impressive 710 basis points improvement in margins was primarily due to a higher mix of revenue from manufacturing versus installation activity, as well as better raw material costs and operating efficiencies from our high-return automation enhancements. This strong fourth quarter performance capped off a year of record full-year gross profit, including a 560 basis point margin expansion to a new record full-year gross margin of 37.1%. Higher operating expenses for the quarter mainly reflected higher variable expenses related to shipping, as well as COVID-19-related expenses. For the full year 2020, operating expenses improved by $3.9 million year-over-year on reduced variable expenses as a result of our efforts to enhance our lean administrative structure and tight cost controls, along with favorable exchange rates. As a percentage of revenue, operating expenses were higher compared to 2019, primarily due to lower revenues and COVID-19-related expenses for most of the year.
Overall, our highly efficient manufacturing capacity continues to generate strong returns and profitability. We remain confident in our ability to sustain our industry-leading margins, and we believe we can source additional pathways to improve efficiencies and reduce our cost base in 2021. Looking at our improved balance sheet and leverage profile on slide number 10. During 2020, we generated record operating cash flow, which improved by $45.8 million year-over-year to $71.4 million, helped by higher profitability and strong working capital management. This represented over 70% of our 2020 adjusted EBITDA, an encouraging accomplishment. With our high -return investments nearly completed by the second quarter of the year, 2020 CapEx of $18.3 million was associated with the completion of these initiatives and with maintenance-related CapEx. Taking into account CapEx, we achieve a record full-year free cash flow of $53.1 million.
As a result of our exceptional cash flows, we were able to improve our liquidity position significantly to end the year with a cash balance of approximately $70 million and a conservative leverage profile of 1.6 x net debt to adjusted EBITDA, down from 2.3 x in 2019. This balance sheet strength supports our ability to execute on future growth initiatives, along with our direct returns to shareholders through our dividend payout. In addition, last quarter, we announced a new $300 million senior secured credit facility. This facility consists of a $250 million term loan and a $50 million committed revolving credit facility with an extended maturity date by three years to 2025. The new facility comprises an initial interest rate of LIBOR plus a spread of 3%, which will decrease to a level of 250 beginning in April of 2021, based on our conservative net leverage at year-end.
This will represent an over 400 basis point reduction from our weighted average interest rate of 7.4% previously. As expected, after the step-down in redemption price in late January, we paid down our existing $210 million of senior notes, which had an interest of 8.2%. This will significantly reduce our amortization schedule and cash interest expense. We estimate aggregate savings will be approximately $11 million annually. The recapitalization of our debt structure will significantly enhance our financial flexibility to execute on our growth objectives as we move forward. To that point, recent conversations with Saint-Gobain have been very encouraging as far as the advancement of the new construction of the new float glass plant. The current existing operation is at capacity, and demand for the new capacity looks strong. We will provide more color as we move along into the year. Moving to our outlook on slide number 12.
Based on our positive momentum to close out 2020 and a solid start in the first quarter of 2021 based on strong orders and invoicing year to date, we look forward to achieving solid growth for the full year. We are pleased to provide a full-year 2021 revenue outlook of $400 million-$415 million, representing growth of 8% at the midpoint. We expect higher year-over-year growth in the first half of 2021, based on anticipated timing of invoicing in 2021 compared to 2020, as well as having a full schedule of operation without any COVID-19 related constraints as we had in March and April of 2020. In addition, we expect to have a higher mix of product versus installation revenue.
We continue to expect the U.S. to represent the significant majority of our growth, led by single-family residential, with stronger demand in the U.S. expected to offset the slower recovery in our Latin American markets. Based on this sales outlook and anticipated mix of revenues, we expect full-year adjusted EBITDA to be in the range of $100 million-$110 million, represented almost 7.5% growth at the midpoint of the range. Gross margins will continue to benefit from our previously completed high -return CapEx investments in automation initiatives. To reiterate an important point we mentioned last quarter, as our market and raw material costs stabilize over the next several quarters, we expect gross margin to trend back towards our previously communicated mid-30s range.
We expect CapEx in 2021 to approximate $10 million-$15 million, primarily related to maintenance projects and some incremental automation in new processes within the factory, which should be completed by the end of the year. With the strength of our balance sheet and financial flexibility to execute on new opportunities, we are confident in our ability to achieve our growth objectives while maintaining our industry-leading margins. As we move into 2021, we remain focused on maintaining our strong track record of cash flow generation while expanding our addressable market in single-family housing and continuing to execute on our attractive backlog of multi-family and commercial projects in the U.S. With that, we will be happy to answer your questions. Operator, please open the line for questions.
Thank you. We will now begin our question -and-answer session. If you like to ask a question, you may press star one on your telephone keypad. A confirmation tone will indicate your line in the question queue. You may press star two if you would like to remove your question from the queue. For participant using speaker equuipment you have to pick up your handset before pressing the start key. Our first question comes from the line of Timothy Wojs with Robert W. Baird. Please proceed with your question.
Hey, good morning, guys. Nice close to the year, and good to hear things are off to a good start in 2021.
Good morning, Tim.
Hey. Maybe just a big-picture question. I'm not sure how to answer this, but is there any way to kind of frame new orders and kind of backlog? How much of it is coming from newer customers versus really leveraging existing or older customers? Really what I'm trying to get at is, are you seeing accelerating traction in the U.S. with newer contractor customers, not just in residential but also in the non-res business?
Yes. This is José. Let me tell you this. We are penetrating a lot in the Northeast. Our backlog in the Northeast is the highest we have ever seen. In Florida, it's been softer in the high-rise, higher in the mid-rise, and residential is not even there because residential, we have a turnaround of six weeks or less. Our backlog for residential is very minimal .
Okay. That's helpful. Then I guess on the residential side, are you seeing an opportunity in the Southeast from a production standpoint? Really why I'm asking is we've seen a lot of window companies in the U.S. that are having labor challenges, and their lead times are extending. Are you seeing the benefits from that? Are you expecting that to kind of be a nice tailwind in 2021 for resi?
Yes, we are. We are hoping to increase residential by 40% - 50% this year. It's unbelievable the demand that we have because everybody has huge lead times, and our lead times are shortening. We have the best of both worlds: a high demand, and we have no constraints on labor, very cheap labor, and we are improving our production capacity. My brother has done a marvelous job in automating and improving productivity, and we are even shortening our lead times. We had lead times from 6 - 10 weeks, depending on the product. Now we have all lead times at six weeks, and we are delivering in five or less.
Okay. That's fantastic. I guess the last one I have is just on free cash flow. You had a really strong year in 2020. I guess as we look at 2021, what are kind of the pluses and minuses from a free cash flow perspective? I guess maybe more broadly, you've taken the leverage down, you've extended the maturities, and you've made a lot of CapEx investments already in the business. What are kind of key, I guess, cash flow or capital priorities over the next couple of years from your perspectives?
All right, Tim. Basically, the first priority would be to reinvest in working capital. Based on our guidance, we are projecting growth as opposed to top-line contraction last year. We're obviously going to reinvest in the business that way. CapEx, as you heard from the call, is going to be reduced this year from what you saw in the last couple of years with a lot of the automation being completed. However, we are seeing some opportunities to further automate a portion of other processes within the factory. Cash flow is going to benefit from having a lower CapEx this year as well. From a capital allocation perspective, I think it makes sense to continue paying down debt, reinvesting in the business, and seeing what opportunities come about.
We are definitely expecting to build on what we produce as far as cash flow in the last couple of years. There's also going to be some tailwinds to that. Obviously, having $11 million less in interest expenses is going to help quite a bit. Also expecting higher profitability based on higher margins is going to drive incremental cash flow. I think we're well-situated to reinvest in the business, pay down leverage, and see what opportunities come about.
Okay. Great. Well, good luck on 2021 and great job on 2020, guys.
Thanks, Tim.
Thank you.
Our next question comes from the line of Brent Thielman with D.A. Davidson. Please proceed with your question.
Great. Thank you. Congratulations as well on a great year. I wanted to poke around on the single family business. Wanted to get a sense of how impactful Multimax has been within that more than 50% single -family growth you reported this quarter, versus the legacy products you've offered in that business.
Hello. We are just starting to sell the Multimax. Multimax is especially for the low end of the market, where we were not even there in the business. We started to see a lot of demand for that product, especially in tract homes where we were not. We hope that by June, it's going to pick up a lot because those are businesses that you sell the windows to, and they don't order them for three or four months or maybe even longer, not like the usual remodel and replacement and new construction that they order immediately. We are very excited and very positive about our residential line.
Okay, not very impactful at all this quarter. Sounds like it's going to ramp up here a lot in 2021.
Yeah. Well, the whole residential line is picking up a lot of steam. What I mean is, the Multimax is going to really hit the numbers after June. The other lines, for example, the first two months, have been great in the residential so far.
We just lost the speaker's line. One moment. Santiago, if maybe you could take over right now. One moment.
Yes, I'm here, Brent. Just to finish what José was saying, Multimax did not add a whole lot during Q4. I mean, that was just getting started. What you saw as a pickup was from Elite and Prestige. It was the legacy business. Hello?
As a reminder, ladies and gentlemen, it is star one to ask a question. Our next question comes from the line of Mike Shlisky with Colliers Securities. Please proceed with your question.
Hey, good morning. Can you hear me okay? Is this Santiago?
Yeah, I can hear perfectly, Mike. Yeah. How are you?
I'm great. How are you?
I'm doing well, thanks.
Good. I guess I wanted to ask, you've always talked in the past about how your company has some great advantages in shipping costs and shipping container availability. We've been hearing some headlines about how, in some parts of the world, it's been a little bit tougher to find some containers recently and some boat capacity. Has that been an issue for you guys at all? Is that something that could happen going forward, or do you feel pretty good about the Colombia-U.S. lines right now?
No, we're actually, one of the great advantages of being fully vertically integrated is that we're not kind of reliant on an extended supply chain from many other places, right? We source most of what we need internally. We're not relying on anybody to significantly contribute to our supply chain. From that perspective, that has not been the case. Furthermore, as you know, we have quite a bit of a trade imbalance with most containers coming in from value-added imported goods from the U.S., come back pretty much empty, right? There's still a lot of supply of containers shipping back into the U.S. No, short answer to your question is no, we have not been impacted by shortage of transportation.
Can I ask a question that's kind of similar on the cost of aluminum for some of your extrusions? Any changes to raw materials there we should be looking at in the next couple of quarters?
Well, this is Christian. We fixed the price for the whole year of 2021, so we have no aluminum increases for 2021, and we already bought everything that we need for 2021. We're fine. As a matter of fact, we were able to get magnificent prices, not only for the LME, but also, there is a premium that you have to pay, and we pay at the lowest premium possible. Now they have gone up to double the premium price that we pay. We're set up in glass and in aluminum. Like my brother said, the lines are steaming, producing windows, and February was the best February in the history of the company.
Outstanding. If I could squeeze one more in here about, and I asked this question last quarter about COVID conditions within your facilities, can you update us on whether cases are trending upwards or downwards in the Barranquilla area, in your facilities themselves?
Well, today we only have five or six active cases of COVID out of 5,700 employees. We are doing really well. Everything is contained. We haven't had any hospitalizations in the last five or six months. The numbers are dramatically down in Barranquilla, where we are. It's looking good.
In Colombia, in Barranquilla specifically, in our city, we have what is called the herd immunization. Already 72% of the people have antibodies. We're doing really great on that end.
Wow. That is great to hear, guys. Thanks again, and stay well.
Thanks, Mike. Talk soon.
There are no further questions in the queue. I'd like to hand the call back to José Manuel Daes for closing remarks.
Thank you , everyone, for participating in today's call. We're gonna keep having great news. Our company is aligned for better things, and we are making a kill. Thank you.
Ladies and gentlemen, this does conclude today's teleconference. Thank you for your participation. You may disconnect your lines at this time and have a wonderful day.
