A Black entrance doorHighly Secure Composite Entrance Doors

We realise the importance of security when a homeowner selects a door because it is the main entrance to a home. That is why our attractive and highly secure composite doors are becoming a popular alternative to PVCu and wooden doors.

Our low maintenance composite doors from Solidor are made from solid timber, utilising a durable plastic edge banding and two thermo plastic door skins. This means that you will never need to re-paint or varnish your door.

You also don’t have to compromise on style because we offer a number of colour designs, such as wood grain and mahogany, that will give you a great looking door that your friends and family won’t believe isn’t pure timber.

There are also a number of glazing and furniture options available so you can customise your door with good looking features such as handles and door chains.

What’s most often associated with a Seal-lite composite door is security, and our composite doors have been stress tested and awarded Secured by Design accreditation.

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.

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.
