R-Value**

Our inserts have 94 % of the insulation of a standard double pane window! The interior surface of the Indow Window is much warmer than the inner surface of a pane of glass, so you’ll feel warmer even if the air temperature in both cases are the same.

** R Value measures the thermal resistance of a material and it’s effectiveness at keeping the outside out and the inside in.

50-70% Decrease In Sound Penetration

An unexpected Indow Window benefit is the remarkable sound reduction. When placed over an operable single pane window, Standard Indow Windows dampen noise up to 10dBA, which equates to a 50% noise reduction. Acoustic Grade Indow Windows reduces noise by up to 18.9 dBA when placed over a single pane window, equivalent to a 70%+ reduction and allows you to sleep through the sounds of traffic, planes and trash collection.
