Dear Customer
As part of the governments overall strategy to reduce energy
use and CO2 emissions new building regulations have been issued
, approved document ‘L’, effective from 1st April
2002 , stating that all replacement windows and doors with
more than 50 % glazed area must conform to a specific energy
value or ‘U’ value of ;
2.0 W/m2 0K , ( watts per square metre, per degree Kelvin
) .
Timber windows and doors made and installed by GBS Joinery
now comply with document ‘L’ and achieve the required ‘U’ value
by the use of double glazed units with a 16 mm air gap and
low emissivity coated glass in the form of Pilkington ‘K’ glass
and draught stripping of all opening windows .
The only consideration for easement of the regulations are
listed buildings and conservation areas. It would be advisable
to seek therefore the opinion of your local conservation officer
before any work is carried .
The installation of replacement windows now requires building
regulation approval and certification , to including document ‘L’,
conservation of fuel , document ‘N’, protection
against impact and document ‘B’ , fire escape .
Although GBS meets the vetting criteria for the self certificating
scheme known as FENSA there is no requirement or obligation
to participate in the scheme we are not a participating company
. Inspection and certification of installations by GBS will
be carried out by an RICS ( Royal Institute of Chartered Surveyors
) approved building inspectors or your own local authority.
Windows supplied for new build or extensions to property where
the project is already covered by building regulation approval
and inspection , require no further inspection or certification
.
The replacement of casements or sashes within retained main
frames requires no certification.
Ultimate responsibility for compliance lies with the property
owner , however every assistance will be afforded to customers
by GBS including detailed specifications and drawings if required.
Please note that certification will be required by future
prospective purchasers of the property their surveyors , solicitors
and lenders .
Non compliance of the building regulations will be in direct
breach of the Building Act 1984 and or Building Regulations
2000 and may result in enforcement .
I trust this is explanatory and informative however should
customers require further information or clarification please
contact GBS directly .
