Fensa Registration - what does it mean?

Since 1st April 2002 all replacement window installations in England and Wales have been subject to Building Regulations. The initials F E N S A stand for Fenestration Self Assessment Scheme. IWC is registered with FENSA (Registration number 24945).

The 70mm profile is 5 chambered with 3mm outer wall thickness. The inner chambers (5) are reinforced with box section galvanised steel for added strength and rigidity. The frames come complete with multi point 'espagnolette' locks on the openers.

The standard glass units are of 4-20-4mm (28mm overall) construction with Pilkington 'K' Glass TM inner leaf. A range of patterned glasses from the Pilkington range is also available. The glass for doors and patio doors is toughened (toughened Pilkington 'K' Glass TM)

OTHER REQUIREMENTS COVERED BY BUILDING REGULATIONS

You may need to ensure that the design of the window will make it comply with the other relevant parts of the Building Regulations which are, briefly:

• Means of escape in case of fire
  For all habitable rooms, with no separate means of escape, in case of a fire there must be a means of escape via the window (minimum sizes apply). In practice this usually means a side-hinged sash fitted with 'Egress' hinges.
• Use of safety glass for low level glazing and adjacent to doors
  All doors and windows adjacent to doors, low level glazing, i.e. when the glass is less than 800mm from the floor.
• Ventilation
  For replacement windows the general rule is that the new window should not make the situation worse in terms of the number and size of the openers.
  The use of night vents may help to overcome conflicting criteria of design and regulatory requirements.

We can give you specific advice on this or you can obtain guidance from your local Building Control Office. You may need to obtain a Certificate of Compliance.

Note: if your windows and doors are part of a newbuild or extension for which Building Regulations have been granted, then you will not need additional certification as the relevant areas of legislation will have already been covered and the specification for the windows will be clearly shown on the plans.
