As from July 2002 all new and replacement windows and doors are regulated either by either FENSA or your local council.
FENSA is a governing body that means most window companies would join and then do what they call self certify their installations each time one is carried out.
As a member of FENSA each company is subject to inspections throughout the year to be sure that they are fitted correctly within the FENSA remit.
The glass that we all should be fitting is called a low emissions glass (low ‘E’). This is to reduce the carbon emissions from your property, thus helping to reduce the effect on the O Zone.
We are also checked to make sure that safety glass is fitted where required by law.
There are other FENSA regulations that we must adhere to such as size of opening, fire escapes and ventilation.
