| Super Spacer Thermal Glass |
| |
| Vinylbilt windows feature our 100% non-metallic exclusive White S-Class Super-Spacer®, engineered to reduce heat and cold transfer between the glazing panels. It is virtually 950 times less conductive than aluminum spacers and is also 85 times less conductive than stainless steel. This same technology keeps inside air cooler in the summer. |
