What is FENSA?
FENSA stands for Fenestration Self-Assessment Scheme. It is a competent person’s scheme and industry standard founded by the GGF.
When a homeowner commissions new windows, doors or roof lights to replace existing glazing they are required to ensure that replacements comply with current thermal performance standards and Building Regulations. To do this they need to get a certificate stating that the glazing is compliant.
To get this certificate they can either:
- Apply to their Local Authority Building Control with all the information about the replacement window.
- Get a FENSA Approved Company to replace their windows/doors who will issue the certificate
A FENSA Registered company has had their windows/doors pretested to show they adhere to current Building Regulations standards for thermal insulation. They will also have had their installation techniques inspected.
A FENSA company can then issue a certificate of compliance for the homeowners records without them having to contact the Local Building Authority.
FENSA only applies to replacement windows/doors.
Are IQ FENSA Registered?
FENSA only applies to replacement windows/doors. For example, where an existing window is being directly replaced (like for like) with a new one. It does not apply to extension builds or new build homes.
IQ are not FENSA registered.
The works that IQ undertake are far larger than simple replacement window installations. For this reason, FENSA certificates would not be applicable to the large majority of works that IQ undertake. We work mainly on larger projects which include building works, extensions, or substantial renovations.
These larger building works require more complicated compliance procedures including SAP calculations, building control sign off and planning permission. These compliance tests are managed and run by the project architect or main contractor.
IQ Glass can supply full performance information for our architectural glazing installations, including thermal performance. These can be incorporated into the larger compliance reports for the project.
Compliance with Building Regulations
All of our architectural glazing products comply with UK Building Regulations, including Part L for thermal performance.
In many cases architects will have specific performance criteria for their projects which surpass the requirements from Building Regulations. IQ work closely with project architects to engineer our architectural glazing specification to ensure it meets the performance requirements.
You can find out more about Building Regulations Part L for Architectural Glazing in our technical articles below.
Other areas of building regulations to be aware of are Part K for impact resistance and Part Q for security (applies to new build projects only).
If you have any questions about the performance of the glazing provided by IQ please get in touch with the team. We are available and able to answer your technical performance questions.
