The Insulating Power Of A Composite Door

There are various qualities that you should look for when buying a new entrance door for your home, security being at the top of the list, and a composite door certainly gives you that. You mustn’t however overlook the thermally insulating properties of the door as you could say that they’re equally as important. Composite doors fit the bill in this respect too.

First developed in the 1990’s, composite doors are composed of a number of building materials including UPVC and wood. They also contain a Glass Reinforced Plastic (GRP) skin and at the core of a composite door is thick polyurethane foam. Putting all these constituents together makes a composite door amazingly energy efficient.

Any draughts that used to infiltrate your hallway or the rear of your house will be gone for good once the installation of a composite door has been concluded. Heat loss will also be minimised. This will put less strain on your boiler during the coldest periods of the year and subsequently cut the cost of your heating bills.

Composite doors do cost more than standard UPVC doors, but when you calculate the savings you can expect to make during the lengthy lifespan of a composite door it easily justifies your investment as it pays for itself over time. So, try not to think about the money spent too much as you will get it all back, and more!

UK Building Regulations currently require all doors including the glass and frame achieve a U-value of at least 1.8 W/m, a U-value indicating the rate and amount of heat that passes through a door. Composite doors offer a U-value that easily meets that standard.
