One of the ways Masonry & Glass Systems ensures that our Restorations windows have leading edge air infiltration ratings is that each window comes wrapped in expanding foam at the jambs and head or top of the window.

This foam is compressed at the factory so that once the shrink wrap is removed the foam slowly expands into the opening left by the old window.

We will then pack fiberglass under the sill of the window from the outside so that almost no air can leak between the New Restorations Replacement Window and the opening in the house. When you combine this installation technique with the design of the Restorations window from Sunrise you achieve an air leakage rating that is 30 times the industry standard.
