We Care About Our Planet
We’re a company that prioritises sustainability. That means that the products that we manufacture and supply are recyclable, helping us reduce waste.
With new recycling facilities available, it’s now possible to achieve bay windows that are more recyclable than ever before.
Government regulations are gradually tightening around recyclable materials and reducing waste in construction. You can make sure that your projects are future-proofed against the inevitable rise in government standards.
Please contact us so that we may offer assistance in making the most of our innovative products.

Technical & Testing Coverage on Products
Our bow and bay windows go through a battery of tests to make sure they are up to British standards.
For this reason, we guarantee that all of our bow and bay windows are completely weatherproof, windproof, and airtight.
We also provide extensive testing to ensure the highest level of security. You can speak with our team individually about locking systems.

Frequently Asked Questions
Do you install?
No. FastFrame is a supplier of bow and bay windows to trade and commercial enterprises only.
Do you deliver?
We do! We deliver nationally.
What profiles do you offer?
The specifications we’ve listed for our bow and bay windows are from the Deceuninck 2500 Heritage Chamfered. We also provide the 2800 Heritage Sculptured profiles, not to mention fully reversible windows.
Do you recycle PVCu?
FastFrame is not a recycling facility. However, we can get you in touch with other companies that can help you.
How long are your lead times for bow and bay windows?
We provide stock of standard colours. However, if you’re looking for specialised colours, it can add two weeks to our standard lead times.
What is Linktrusion?
In typical PVCu construction, galvanized steel reinforces the inside of standard PVC window frames. However, steel is not needed thanks to the cutting-edge Linktrusion technology developed by Deceuninck.
One metre of PVC window frame profile contains 200,000 metres of glass fibres, which is why Linktrusion is utilised in two different ways: either as a recycled PVC foam core with steel wires and a PVC skin or as continuous glass fibres embedded in the profile.
