Strongest Corner with four layers of protection.

All windows transmit at least tiny amounts of moisture vapor through the material around the edge seal. But the longer the path, the better and longer the seal protection. Intercept has the industry’s longest vapor transmission (MVT) path by up to 50%. Combined with our exclusive corner technology, this virtually eliminates seal failure and gas or air loss.

Superior warm-edge performance.

Best retention keeps the gas or air in the windows.

Straightest and most secure grids for beautiful windows.

Intercept Spacer minimizes condensation and keeps the edges of window glass warmer than a conventional spacer. Its special metal alloy and continuous one-piece “U” construction are why. This results in windows with higher R-Values that save energy and keep your rooms more comfortable in both cold and warm weather. Introduced over a decade ago by PPG Glass Technologies, Intercept has proven superior in over 600 million glass units in North America.

The Intercept Spacer System features a unique, one-piece, tin-plated or stainless steel, U-channel design that creates an effective thermal barrier to help reduce conducted heat loss through the window. Its sealed, one-piece design makes Intercept spacers stronger and better at retaining insulating gas than many conventional designs.

Intercept Spacer System

Insulating glass units expand and contract with temperature changes. Conventional spacers rely on the sealant to take the stress of the flexing. This leads to seal failure and insulating gas or air loss. Intercept’s U-shape channel flexes instead of the sealant--Durably and enduringly. No load on the sealant virtually eliminates seal failures which keeps your windows preforming longer, saving energy, and keeping your home comfortable.

Patented U-shape construction makes windows last longer.

With Intercept, you just won’t see grids that have shifted or don’t match up from one window to the next. As part of Intercept’s exclusive manufacturing process, grids are made consistently to match precisely, and they’re uniquely locked in place. Plus, Intercept spacers are specially recessed below the sightline. All you’ll ever see are beautiful windows, for years and years.

Spacers that utilize foam or have seams are just destined to leak gas out of their corners. Not only is Intercept a continuous one-piece spacer, it features our patented web corner system and exclusive four layers of protection. No one puts more technology into protecting the seal all the way around the glass to bring you assured, long-lasting window energy performance.
