U value for windows and doors

The rules with regard to the thermal efficiency of windows and doors has been updated recently so all new windows and doors have to have a u value of a certain value which does vary depending on the type of building. Custom Wood Products can provide the calculated u value for windows and doors we manufacture.

From 2013 all new windows should be CE marked
