energy efficient five chamber profile Green Credentials

All our window and door frames are manufactured using a five chamber PVC profile reinforced with Recycled Composite Material (RCM). This enhances the thermal performance of our products and improves the ‘green credentials’ of your business. Furthermore, all our windows are energy Rated ‘B’ as standard.

The energy rating logo is used on many household goods – including fridge freezers, cookers and boilers – giving installers who sell energy rated windows an advantage over the competition.

And because our windows are manufactured using an energy efficient five chambered PVC-u profile, we can achieve an ‘A’ Window Energy Rating without the need to incorporate expensive sealed units – saving you money and meaning you can offer your customers a competitively priced energy rated window.

Why choose Seal-Lite to provide your windows and doors?

We recycle your old windows and doors

window recylingRecycling

At Seal-Lite we don’t see recycling as just another buzzword or box-ticking exercise but as a commitment to improving the environment that we all have a stake in.

Household waste recycling is on the increase in the UK and traditionally glass, paper, aluminium, textiles and green waste were included and double glazing PVCu doors and windows were reserved for landfill.

With Seal-Lite you can recycle your old PVCu windows and doors so they end up becoming a new generation of products rather than being buried deep in the ground.

Double glazing PVCu house windows and doors have an average lifespan of 35 years and can go through the recycling process more than ten times before they lose performance capabilities – meaning that PVCu is one of the most sustainable materials in the house-building industry! So recycle your double glazing house windows and doors with Seal-Lite.


Experienced to help you choose the perfect products

help advisor who can offer advise on your productsOur experience

Based in Clevedon in the South West of England since 1987 we were originally manufacturing and installing just aluminium windows and doors. However, as consumer attitudes changed we began to manufacture and install PVCu house windows, doors, conservatories and garage windows.

Manufacturing and installing windows and doors in Clevedon, Weston-super-Mare, Nailsea, Portishead and Bristol for over 20 years means we have plenty of experience in delivering high quality home improvements.

We currently employ a loyal group of 30 staff and turnover is low. This means we understand the world of windows, doors and conservatories inside out and have the knowledge to offer a comprehensive and professional service, whether you are in the trade or a homeowner.


A great range of energy efficient windows, doors and conservatories

Energy efficiency

Our A-rated energy saving double glazing windows and thermally secure conservatories can save you money on your energy bills and help the environment.

Seal-Lite's range of aluminium and PVCu windows, doors and conservatories meet energy efficiency standards set by the regulatory body – the BFRC. Because our products reduce heat-loss and prevent draughts, along with saving money on your heating bills you will also have a more comfortable living environment.

Energy efficient double glazing also reduces the amount of harmful emissions that can pollute the environment – so as well as saving money and improving your lifestyle, you can help the planet too.
