Energy Efficiency

With the Ventrolla Perimeter Sealing System air changes per hour (ach) are substantially reduced, creating a potential for energy saving.

A building with sash windows in an exposed position will probably have 2.5 to 3 air changes per hour.

Incorporation of the Ventrolla Perimeter Sealing System to all windows and doors can reduce air changes per hour to the adventitious rate of 0.7.

By reducing air change rates the energy required to heat up the building is significantly reduced.
