The Vivid Color™ System

Our BetterVue screens are so clear that they almost look invisible. This means that the BetterVue screen itself is not clearly visible in ones view from a distance. In fact, you’ll find that you only notice the screen as you get close to it – a feature designed to ensure that your guests won’t walk into the screen but clear enough to give you unobstructed, perfect views all the time. 

And not only is the BetterVue screen system a perfect screen for anyone wanting to enjoy the best view of the outdoors, but the screen is also flame retardant, and by design the BetterVue screen system allows more airflow into your home while still protecting against those pesky pests.

The all-foam formula of Super Spacer blocks the heat path, so homes stay cool and comfortable inside.

The dual seal system helps Super Spacer insulating glass units last up to five times longer in durability tests than single-seal units.

The all-foam formula offsets the effects of temperature changes, baromatic pressure, window load, and glazing pressure. The end result is less seal failure and fewer stress cracks.
