Bryn Mawr II vinyl replacement windows

CertainTeed has introduced an advanced design for its Bryn Mawr II replacement window. Featuring chambered solid-vinyl profiles that never warp or swell and never need painting, the 3/4-in. constant-force, stainless steel balance system ensures that sashes open easily and never sag or stick. For air and water performance, the window features a welded sloped sill with a 1-in. welded-sill dam, fusion-welded sash and frame, double weatherstripping and integral glazing.
