NEW -Tougher Government Glazing Regulations

All new or replacement windows have to comply with the Government's new tougher heat retention regulations, Document L.

Document L deals with the heat saving properties, the "U-value", of windows. The better heat saving properties, the lower the u-value.

All new or replacement sash windows, hinged windows and glazed doors have to be manufactured to meet the new, higher demands on insulation, giving you more warmth and comfort as well as better heating economy. In fact, it means that, unless it is a listed building, the new or replacement windows have to be double glazed, whether or not they were before.

Window manufacturers products are tested and accredited for compliance by the National Physical Laboratory. Windows will be supplied from the manufacturer with certificates that authenticate compliance.

The responsibility for the compliance lies with the installer via the Local Planning Authorities Building Control Department.

To ease the burden the new regulations place on Local Planning Authorities, a new organisation FENSA (Fenestration Self assessment) has been launched.

Qualifying members are able to self certificate their installations to show compliance.

Making the Grade

The Original Box Sash Windows Company has had all its is products individually tested and and certified by the National Physical Laboratory.

The Company is a certified member of FENSA. As we only install our own products, we can guarantee compliance and will handle all aspects of certification with your Local Authority.

This ensures in any future search on your property, the correct certificates will be available to a prospective purchaser etc.
