Comprised of 3 panes of (low-e2) glass, sandwiching two further separating pockets of argon insulating gas, this industry improvement vastly outperforms its earlier, double-glazed predecessor; not only in providing a superior thermal insulation barrier to keep you lovely and warm, but by further reducing the possibility of conducting condensation and the transmission of outside noises. The advancements within this product have acredited the manufactures to achieve the lowest U rating performance for a commercial window.
