Window FAQs
Quick answers about choosing and installing new windows.
Do You Install Fire-Rated Windows?
Yes. We partner with Optimum to supply and install code-compliant fire-rated windows, doors and glass, including for lot-line conditions under the NYC Fire Code.
Can You Replicate Historic Windows for Landmark Buildings?

Which Window Material Is Best?
It depends on the building, budget and look you want. Wood offers timeless beauty, aluminum and steel offer slim sightlines and strength, and vinyl and fiberglass offer value and efficiency. We will recommend the right fit.
Do Sound-Reducing Windows Really Work?
No window is completely soundproof, but multiple panes, varied glass thicknesses or an interior storm window can reduce street noise significantly.
