General Performance of Windows and Doors
Our WinMark General Performance schemes help to provide the assurance that any window and door manufactured meets the guidelines of the relevant British Standards.
The WinMark Scheme for the General Performance of Windows & Doors is an entry level certification scheme covering products manufactured to British Standards for most of the common material types.
