Internal Grids

Canglow’s Internal Grids are available in two styles, Traditional and Prairie that come with Cardinal Glass. Ordinary glass is less effective owing to the less insulating value of its coating. With Canglow’s Cardinal Glass you can be assured of doubled insulating value due to the patented coating that reflects heat back into the house in winters helping it to remain warm while in summer it rejects the heat and harmful UV rays of the sun. This patented coating is virtually indiscernible but yet blocks 85% of the damaging ultra violet rays that makes it the clearest and highest performing glass that you can get for your door.
