Isolating Interior from Exterior Conditions

The building envelope is what separates the building interior from exterior conditions. In cold, harsh climates, it is especially important to have a strong building envelope to minimize heat loss and protect from rain and snow. Vestibules, storm doors and storm windows provide an extra layer of separation from exterior conditions further enhancing sustainable performance.
