RATINGS EXPLAINED

The thermal performance of a front door can be measured by its U-value, the lower the better. This demonstrates how effectively any installation keeps heat inside a building, allowing you and your loved ones to enjoy total comfort and absolute peace of mind.

Most Endurance composite doors are manufactured with the impressively low U-value of just 1.6 – which is a result of their solid timber core, and double and triple glazing styles. You can design your dream door online with our designer tool, allowing you to choose bespoke options for you and your home. While these styles, furniture and glass options can affect the U-value, all thermally efficient composite doors from Endurance will enhance the comfort of your home.

A Rating

Endurance’s A-rated composite doors provide the highest levels of thermal performance on the market today. With an impressively low U-value that represents the small amount of heat transfer that they allow, our front doors will effectively trap warm air inside your living space and keep cold air at bay. A thermally efficient composite door, manufactured and installed for you, will be able to save money on heating bills and make the best investment for your home.

OUR CUSTOMERS' WORDS

Mrs Milbank

Our new door is solid, a lovely colour and draught-proof. The glass fitted lets in light but is not see through from the outside. Lock fitted is far superior to that on our original door and great that the key can be registered and cannot be copied without the security tag.

Mrs Harding

The door is beautiful, well made and solid! The fitters were also incredible who made sure the fittings and door were fitted to perfection. Would highly recommend!

Mr Bernie

Very happy with the choice of door I picked. I feel very secure in my house now. Also no draughts coming in, I will feel nice and comfy in the winter!

ADD AN EXTRA LAYER

TRIPLE GLAZING FOR FURTHER REDUCTION

If you want to enhance your composite doors’ thermal performance even further, you could choose triple glazing over our standard double glazing glass designs. We offer a wide range of glazing styles for you to choose from, with varying levels of opacity so you can stay in total control of your privacy. Additionally, you can refine your look with glass designs that are modern, traditional or something in between to suit you.

If you want to combine bespoke style with the highest thermal performance levels, choose triple glazed glass for your composite door glazing.

A SOLID TIMBER CORE

The solid timber core of an Endurance door is one of the many features that sets our composite doors apart from others on the market today. At 48mm, the solid core on our doors is 10% thicker than most alternatives, including cross-laminated timber for a design that is stronger and more durable than others. With this in place, it is much harder for heat to escape and for cold air to break through, creating a tough and resilient exterior for your comfort.
