||Looking for more than just your average vinyl window?
Our Starmark window is made from a solid cellular composite. Unlike vinyl windows that have hollow frames, the Starmark window has solid frames and solid sashes just like a wood window, but without all of the undesirable traits associated with wood windows. The Starmark composite window will not rot, warp, twist or swell up like a wood window when it is exposed to moisture or humidity. Because the construction is with solid material, there is no need to inject a spray foam insulation like you see in many vinyl windows. The composite material itself is an insulator, so along with the Heatseal non metal spacer and 11 layers of reflective material in the low e coating, the Starmark window offers outstanding Energy Star ratings.
