Research indicates that although windows account for approximately 8% of the total building envelope, they account for approximately 60% of unwanted heat loss in cooler months. This loss can be reduced by simply eliminating cold draughts from around the windows and doors and reducing the cold being transferred through the glass.
One cost effective solution, which does not involve major structural work, is to fit timber shutters on the inside of glassed areas. OpenShutters supply custom-fitted Western Red Cedar Shutter with blades that rotate 180 degrees. Research has demonstrated that Western Red Cedar Shutters reduce heat transfer by up to 49%, while custom fitting into the reveal reduces draughts. The installation of Western Red Cedar Shutters is a long term, environmentally sustainable, comfort solution.
