Black Millwork, the all round supplier of timber windows and doors, is extending its significant portfolio to include a high-quality triple glazed option across a number of its products. <br> <br> A popular specification choice in Scandinavia, triple glazing is designed for builds in exposed locations or extreme weather conditions, where maximum thermal efficiency is required. In addition, triple glazing provides increased acoustic performance, making it suitable for properties near main roads or other areas where noise reduction is a consideration. <br> <br> Triple glazing will be available for a number of products, including the H Frame, tilt and turn, and flush casement windows. Black Millwork says it is the only manufacturer that is able to offer triple glazing for traditional sliding sash windows. <br> <br> Offering a solid specification solution with the added benefit of increased acoustic performance, triple glazing will complement Black Millwork’s existing range of patio doors, with the inward and outward opening hinged French doors, the timber and aluminium clad sliding doors and the bi-fold patio doors all available in a triple glazed option. <br> <br>
