Air Infiltration, Window Seals and Drafts

Air Infiltration

Air infiltration causes cold drafts and temperature differences within a room, which frequently causes the thermostat to be set higher, so that the average temperature is at the desired level. Soundproof Windows reduces the air infiltration into your home. By reducing the air infiltration, the lower thermostat settings are preferred and the comfort level is significantly increased. As an example, without air infiltration, you will seldom have the scenario of your head feeling warm and your feet feeling cold – because of the reduced draftiness.

Window Seals

Window seals can be fickle. Windy conditions make them leak. Time makes them leak.

Most windows seals typically start leaking significantly within a few years, but our system is different. Soundproof Window seals are guaranteed for 50 years, and we have a fifty year track record to prove they will last.

Our frame seals are held under a constant tension, using custom made tempered stainless steel springs that actively squeeze down on the window – which means our window seal is flexible, constant and always working. These constant pressure seals will perform just as good in 50 years as they do on the day they are installed, and assures you that the air infiltration rates will always be virtually non-existent.

What your current window leaks now, our window will seal out. Soundproof Windows completely neutralize the air infiltration of your current windows.


With Soundproof Windows, drafts created by pressure differences all but disappear. For example, if a door is opened, a draft blows out through the door. The draft pulled air in through the leaking window seals. Now, in practice this draft may blow in through the door or out the door. With the constant pressure seals in Soundproof Windows, the forced pressure drafts are reduced or stopped completely.
