Why do I need a Fensa certificate?

Any homeowner who has had replacement windows or doors (over 50% glass) installed by a FENSA member after April 2002 would be issued with a FENSA certificate.

Companies who are FENSA registered have undergone strict vetting procedures and are routinely inspected to ensure Building Regulations compliance is maintained.

Keep Safe - if you sell your property you will need to produce your FENSA certificate to the solicitor of the person buying your property.  If lost, you can request a duplicate direct from FENSA but this takes time and at an extra cost.

Do you offer an Insurance Backed Guarantee?

Where we install products (excluding repairs and replacement double glazed units) all homeowners will receive an Insurance Backed Guarantee policy direct from The Glass and Glazing Federation Insurance on our behalf.  

Since 2014, it's now a legal requirement that all double glazing installers offer an Insurance Backed Guarantee with any installation they carry out.  This protects your warranty period should a company go out of business.  This is also a good way to sort out the reputable companies from the cowboys.

uPVC or PVCu - which is correct?

They are both correct.

uPVC changed it's name to PVCu in the late 1980's to fall in line with Europe.  Most European languages place the noun (the word PVC) before the adjective (u).  The 'PVC' part stands for Polyvinyl Chloride and the 'u' stands for Un-plasticised.

What is the GGF?

The Glass and Glazing Federation (GGF) is the main representative organisation for companies involved in all aspects of the manufacture of flat glass and products and services for all types of glazing, in commercial and domestic sectors.

The GGF is recognised by government and plays a large part in the setting of new standards and regulations, such as The Building Regulations, the rules that govern and control the way our buildings are constructed in the UK.

When looking for a manufacturer, supplier or contractor for all glass types and glass related products, energy efficient windows or conservatories you should start by looking for a Glass and Glazing Federation Member.

How do you reduce condensation?

Condensation is a result of humidity levels coming into contact with cold surfaces.

The inner glass of a double/triple glazed window will be warmer than the outside which reduces humidity contact.  Rooms require heating in cold weather to raise the temperature of the inner glass unit.  However, when high levels of humidity happen (cooking, showers/baths, boiling kettles, sleeping) ventilation is required.
