Thermal Dam

Our Liniar profiles are designed to Passivhaus recommendations where the thermal dam reduces the heat transfer.

FENSA stands for Fenestration Self-Assessment Scheme. It was established by the Glass and Glazing Federation (GGF) and other industry bodies with Government encouragement in response to the current Building Regulations for England and Wales.

When having windows and doors replaced, homeowners must comply with current thermal performance standards and ensure that they get a certificate of competence from FENSA or from the Local Authority Building Control. FENSA also enables companies that install replacement windows and doors to self-certify compliance under these Building Regulations.

When installing windows and doors into commercial premises, new build properties or extensions FENSA doesn’t apply. In these instances you will be required go through the Local Authority Building Control process. FENSA registration is also not applicable to the installation of conservatories or porches.

When the time comes to sell your property, your purchaser’s solicitors will ask for evidence that any replacement windows and doors with more than 50% glass installed since April 2002 complies with building regulations. There are currently two ways to prove compliance.
Produce your FENSA certificate showing that the work was carried out by a FENSA registered installer or similar body.
Produce a certificate from the Local Authority Building control department that the installation has been approved under the Building Regulations.
