Gilkey Signature Series All Fiberglass Casement and Awnings provide DP 90 ratings that exceed all residential standards.
Our casement and awning windows come with the following benefits:
- They have triple weather stripping, and multi point locking system for ultra-low air-infiltration performance.
- They can accommodate multiple glazing options up to 1 3/8” thick.
- Their interior glazing bead design makes them strong enough to withstand forces as strong as 220 mph winds.
- They boast the highest number of internal chambers, which makes them more insulating and soundproof than windows with minimum chambers.
- Their mounting hardware fits through two PVC walls for maximum sturdiness.
Our casement windows also open a full 90° to give you maximum ease while you clean. And you’ll also enjoy a true lifetime warranty to ensure your windows serve you well for decades to come.
