New Generation Glass

Low-E glass is a form of glass that reflects the sunlight, it allows some of the rays in, and reflects some of the rays. Optima Windows & Doors currently is using a 5th generation Low-E product.

Advance Spacer System

In older windows a single piece of aluminum was used as a spacer, caulked to the two pieces of glass creating a thermal bridge that would result in heat loss. Optima does not use any type of metal in its spacer systems.

Premium Vinyl

When we are talking about vinyl windows, the most important part is obviously the vinyl. It is easy for a manufacturer to save money by making their window frames thinner, but that’s not the case with Optima Windows & Doors. In fact, Optima makes one of the heaviest windows on the market, using a premium, surgical-grade vinyl with no fillers or re-grind. This makes sure that the new windows last a lifetime, with our fading, warping or cracking.
