over to Santiago, on slide six, to discuss the strong demand for a single-family products, vertically integrated strategy, and financial results and improve our look for the year. Thank you Christian. Our third quarter results represent yet another quarter of consistent execution, followed years of investment in technology enhancements, our facilities, as well as strategic positioning in U.S. single-family residential market. In the third quarter, we were thrilled to expand upon our exceptional first half 2021 performance. We saw our momentum continue primarily through share gains and new business wings in our single-family business. This momentum resulted in our total revenue increasing to new record levels, notably our single-family revenues increased 213% year over year. Representing… 213% year over year, representing 48% of our third quarter US revenues, and 35% of our US sales on an LTM basis, reflecting new business wins, and market share again. Our sales continue to benefit from our vertically integrated business model and strategically located operations. The accelerating demand for our products is attributable to our ability to supply superior quality products with shorter lead times at an attractive value. As Chris mentioned, while our single family sales in the third quarter were primarily comprised of our prestige, and elite product lines, we were thrilled to begin invoicing orders for our MultiMax product lines targeting production home builders. Regardless of our future volatility in the housing market, or forward-looking indicators such as housing stats, we expect this product line to offer pure upside to our already strong residential sales, as we continue to focus on expanding our single family presence through dealership expansion and geographic diversification. Looking at slide seven, we would like to draw your attention to the factors driving our success and above market growth in 2021, helping us to differentiate TechnaGlass as the architectural glass provider of choice in the US, as we have discussed in previous quarters, our strategically located vertically integrated and low-cost operations provide us with sustainable competitive advantages compared to our peers. Our structural advantages and significant investments in our operations continue to facilitate our ability to quote more projects, expand customer relationships, and deliver products with much shorter lead times than the current industry average, our vertical integration in joint venture with Sangobond allows us significant control over our purchasing and transportation costs, with no material pressures from raw material costs or material availability. Also, we have not experienced any significant wage cost increases or labor constraints. Additionally, energy costs continue to be stable, given our ability to source energy from our solar panel generation, and natural gas cogeneration. Collectively, it has enhanced our ability to deliver attractively priced products in a timely manner, and in turn, unlock opportunities to build new relationships, entrench ourselves with existing customers, and drive market share again. On slide number eight, we display the areas where we believe we have already made significant achievements across the ESG spectrum. We were pleased to further highlight our commitment to environmental, social, and governance responsibilities through our 2020 sustainability report published a few weeks ago. Throughout our years, as a public company, we have worked to serve all of our stakeholders from implementing green technology, such as our 15 million investment in solar technology for our facilities, to our efforts to develop TechnaGlass as an employer of choice in Colombia, by way of our investments in our employee and corporate culture. On slide nine, we have provided a high level view of the goals we will seek to achieve on a go-forward basis, as outlined in our report. We have designed and continuously implement strategies aimed to encourage the efficient use of materials and resources, as well as the development of environmentally friendly technologies. We also look to responsibly manage the value chain and the lifecycle of the products we sell. And we do all of this to offer our partners innovative and best-in class products that are environmentally friendly and energy efficient. TechnaGlass remains dedicated to corporate social responsibility in our 2020 reports marks another important milestone in our ESG journey. Let's now discuss our third quarter financials, starting with revenue drivers on slide number 11. Total revenues increased 26% year over year to a record 130.4 million for the third quarter. In the US, which represents 94% of our total revenues, we saw growth of approximately 29% to a record 123.2 million, compared to 95.7 million in the prior year quarter. This strength was primarily driven by strong growth in our single family housing activity in market share games that I discussed previously. This more than offset the air pocket in commercial activity, as projects in our backlog that have resumed progress to the latter stage of construction when architectural glass is typically installed. Based on conversations with customers, we believe commercial is on track to recover as we move early into 2022. Looking at the drivers of adjusted EBITDA on slide number 12. Adjusted EBITDA in the third quarter of 2021 increased 36.1% to a record 38.7 million, compared to 28.5 million in the prior year quarter. Adjusted EBITDA margin was 29.7%. A third quarter record in a strong 220 basis points improvement compared to the prior year period. We were pleased to produce record third quarter gross profit on both $1 and margin base. Our gross profit increased 28.7% to 51.6 million, representing a gross margin of 39.6%. This compared to gross profit of 40.1 million in the prior year quarter, representing a gross margin of 38.8%. Our 80 basis point improvement in margin was mainly attributable to greater operating efficiencies in a higher mix of revenue from manufacturing versus installation activity, given our increased mix of single family residential products, where we do not carry out installation. Higher nominal operating expenses for the quarter mainly reflected higher variable expenses related to marine and ground transportation and commissions. As a percentage of revenue, operating expenses were lower by 280 basis points compared to the prior year period, due to higher revenues and better operating leverage on personnel, professional fees, and other fixed expenses. Now, looking at our balance sheet and leverage profile on slide number 13. To reiterate a point made in previous quarters, the recapitalization of our debt structure last October in our outstanding track record of cash flow generation has significantly enhanced our financial flexibility. In the third quarter, we were proud to record operating cash flow of 33 million at an 84% conversion from adjusted EBITDA. Over the past 12 months, we have generated operating cash flow of 114 million, representing 85% of adjusted EBITDA. Our higher margin, shorter cash cycle single family revenues, combined with exceptional working capital management, and low interest expense are all helping to drive additional shareholder value. The transformation in our ability to generate significant cash, left us well positioned to deploy capital opportunistically during the quarter. To that end, we spent 10 million in growth CapEX in the quarter in order to address affected demand. This move aligns with our strategy to invest in further operational efficiencies, and allows us to prepare for the additional growth we expect in the quarters ahead. We expect these investments to be operational late in
