Self Survey Guide

Required Safety Glazing Standards: Approved Document N
When measuring, you must take into account the required use of safety glass in certain areas. The following chart indicates where glass use is a potential hazard and safety glass must be used. When completing your WINDOW or DOOR SCHEDULE, please mark “T” to indicate Toughened Glass and identify this when you discuss your project with our CUSTOMER SERVICE TEAM MEMBER.

Providing Means of Escape: Approved Document B
Current Building Regulations require windows in upstairs habitable rooms – Bedrooms, Home Office, but not Bathrooms – to have adequate fire escape facilities.
There should be at least one opening window or door section in each room which allows a minimum of 0.33m2 or approximately 450mm width and 750mm height. Affected openers should have a “fire egress hinge” fitted as standard, which allows the hinge to move the opening sash to one side, increasing the exit size. Additionally, the foot of the opening must be within 1100mm of floor level to facilitate easy exit.


Ventilation: Approved Document F
Rapid ventilation means that adequate ventilation to a room must be achieved to at least the previous standard of windows being replaced. Trickle ventilation can assist in these situations and is advisable in bathrooms, kitchens and rooms with pre-disposed condensation problems.

Insulation: Approved Document L
Since April 2002, Building Control Standards has required varying insulation values, calculated as U-Values, to achieve heat-retaining qualities in windows and doors. Our windows and doors exceed all standards required and as it is statutory to install replacement windows which meet compliance standards, all products manufactured by us are made to those standards as standard, so no further action is required on the part of our customers.

Customer Service Team Checks
During contact with a Customer Service Team Member, we will check Building Control requirements as the project is assessed and priced.

Be assured that all products supplied to you achieve compliance. Certification of compliance is issued to you following installation.

Please feel free to discuss any aspect of Building Control Regulations with our Customer Service Team Member.
