Vinyl Windows

Key Features

National Vinyl manufactures superior insulated clear glass, Low-E, or Low-E with argon gas windows engineered to meet today's demanding energy standards for thermal performance. National Vinyl is proud to introduce Krypto-Lite a revolutionary triple glazed dual Low-e with double Krypton Gas fill. This process provides one of the best insulating windows on the market with an overall U-Value of .20…that's an R-Value of 5! This will allow us to be one of less than 60 manufacturers Nationwide to be listed on the DOE R-5 program.

By fusion welding our frames and sashes, National Vinyl windows achieve both durability and strength. Sashes and frames are manufactured to be one solid piece with no seams or pieces to break.

Multi-chambered hollows in frame and sash create greater insulating and structural value.

Where the sash meets the sill we use a superior bulb seal which acts similar to the gasket on your refrigerator, providing a tight seal against water and air infiltration. This foam seal has a memory that will keep its shape even after months of being compressed.

Our true sloped sill design provides optimal water runoff keeping you and your family dry.

Vinyl Is "Green"

More than half derived from common salt, vinyl is one of the most energy efficient materials to make. And, when installing vinyl windows in our homes, they often do not need to be scraped or painted as a traditional wood window does. In terms of affordability, durability and renewability, vinyl is a smart, green choice.
