Vinyl Windows

It's easy to know why vinyl windows have become one of the most popular choices homeowners make when building a new home or replacing old and inefficient windows in their homes. Technology strides in the manufacturing of vinyl windows have made them one of the smartest choices for improving a home's energy efficiency and they bring beauty and elegance to a home's appearance. Homeowners also find that vinyl windows require much less maintenance than their wood-constructed counterparts.

Vinyl windows are a "green" choice

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.

In 2011, Yahoo Finance Rates replacing windows as one of the top 5 smart investments in 2011. Watch the Yahoo Finance Video.

National Vinyl's Vinyl Windows

Cross Cut

National Vinyl's windows are constructed with some of the best energy efficient technologies available today. Recent Federal Rebate Programs have set performance criteria for windows and doors to meet a minimum standard of .30 or lower U-Value and SHGC (Solar Heat Gain Coefficient). For years, National Vinyl has been constructing our windows so that they meet or exceed these standards.

 All of our vinyl windows are manufactured with a true warm Super Spacer®SustainaView™ foam insulating glass spacer. Most window manufacturers use metal spacers to separate the panes in a double-glazed window. Spacers that contain metal conduct heat and cold through the spacer. National Vinyl uses 100% structural foam insulating glass spacers to keep the heat in and the cold out.

  1. 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.
  2. 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.
  3. Multi-chambered hollows in frame and sash create greater insulating and structural value.
  4. 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.
  5. Our true sloped sill design provides optimal water runoff keeping you and your family dry.

National Vinyl's Vinyl windows are designed with the homeowner in mind:

  • Slim profile provides maximum glass area – allowing more light in to your home
  • Soft bevel on sash gives you a more elegant and traditional look
