Tighter Houses Create Concern
Indoor air quality is a concern today as most newer homes are being built "tighter" to be more energy efficient. Existing structures have also been "tightened-up" with better insulation, weather-stripping, upgraded windows and high quality exterior doors. Unfortunately, making homes more energy efficient exacts and unexpected price. Indoor air quality suffers as the exchange of indoor and outdoor air is limited. Indoor air pollutants get trapped inside and can build up to harmful levels. These pollutants can range from dust to chemicals to radon.
