At Mitten, we know that quality windows make for a comfy home. That's why we carry Ply Gem's line of designer windows. 

Ply Gem combines the best performance, style, and comfort into one package. Their vinyl window options are designed to look great while providing unparalleled durability, longevity, and efficiency. How do they do it? Well let’s take it step by step.

The frames are made from state-of-the-art vinyl. These vinyl extrusions are formulated to withstand the harshest climates year after year and their multi-chambered design optimizes both strength and thermal efficiency.

Next you have the glass. Depending on the series, Ply Gem’s windows are double or triple glazed. these are sealed units with air or gas between the panes. The sealed portions help insulate your home from heat, cold and outside noise, so not only are you using less energy, you also have a calmer, more restful home. This is particularly helpful if you live in a busy area or have pets that are easily distracted and upset by outside noises (no more bark offs between your pup and the dog down the street).

Then there is the quality of construction. Ply Gem uses tempered glass, which you might also know as safety glass. This is stronger, more durable glass that is more resistant to breakage than standard glass. If it is broken, it won’t shatter into sharp pieces, making it safer for your home and a less appealing option for break and enters.

With Ply Gem's windows your looking at more value, more performance!
