A Guide To Composite Doors

Do you want to know more about making the switch to composite doors? As one of the leading composite door manufacturers and installers in the South West, we’ve put together this handy guide based on your questions.

What is a composite door?

Composite doors are external doors that are made from multiple materials, including PVC, timber, insulating foam and GRP (glass reinforced plastic).

What is the difference between a uPVC and composite door?

While uPVC still makes a great choice for external doors, composite doors use the latest advances in technology to create a stronger, more durable and energy efficient option.

The materials used in composite doors also allow for a far wider range of finishes than it is possible to achieve in uPCV. Realistic woodgrain finishes can come in almost any colour, opening up a range of low maintenance options for your front door.

At CR Windows, we offer a ‘design your own door’ service where you can pick and mix from our extensive range of styles and colours.

Are composite doors more expensive than uPVC?

Yes, as composite door components are more expensive it is a more advanced option than uPVC, the prices tend to be higher.

How long does a composite door last?

Composite doors are extremely durable and can last for many years. All of our composite doors are backed by a 10 year guarantee to give total peace of mind.

Composite doors are also extremely low maintenance, requiring just a clean with warm water every now and again to keep them looking their best.

Are composite doors secure?

Yes, composite doors are incredibly strong and, when fitted with the right locks, make some of the most secure external doors available.

Here at CR Windows, we have invested in a new variety of composite doors with significantly improved security features – our composite doors have 11 unique locking points surrounding the door.

We also provide a wide range of coloured hardware options and can advise you on making the most secure choice for your home.

Are composite doors energy efficient?

Yes, composite doors are much more thermally efficient than either wood or uPVC doors. The warm foam core provides excellent insulation that keeps your home warmer and can lower the cost of your energy bills.

We also provide upgrades to glass options within our composite doors that can further increase energy efficiency.
