Roofing, Weatherproofing, Waterproofing & Building Maintenance Services

Building Envelope

The U.S. Department of Energy, has stated that more than 10% of all energy use in the country is attributed to the condition of building envelopes. Buildings waste energy through gaps and cracks on the envelope construction and could be costing their owners up to 40% more in heating and 15% in cooling costs due to uncontrolled air filtration. These leaks could occur all throughout the building -- at roof/wall joints, doors, windows, roof level changes, electrical outlets and elsewhere.

The solution is an air barrier audit to identify where leaks occur, and an air barrier system to control those leaks.

Your facility may also require a continuous air barrier to comply with local building code requirements
