Heat retention

Any exterior door can be a point through which heat escapes. So, choosing the right fit is an investment in more ways than one.

A door’s primary material, the total glazed area, the type and treatment of glazing, and the types of seals used during installation all determine heat retention.

At least 15% of heat loss in the home can be attributed to draughty and inefficient doors. So, as a Fensa registered company, making sure our doors are as thermally efficient as our windows is incredibly important to us. Similar to the energy rating system for windows, doors are rated A++ to E via the DSER (Door Set Energy Rating).

We’ve achieved this via a number of top-range technologies and features including A+ rated glass as standard, argon gas cavity infills, edged spacer bars, separate chambered uPVC door profiles combined with airtight and weatherproof designs.

Our aluminium range of doors are fitted with thermal break barriers, which effectively resist thermal energy loss; allowing us to offer some of the most thermally efficient aluminium doorsets around.

Our range of high-quality composite doors also feature both single and double rebates, for additional heat-retentive qualities.

Of course, the level of heat retention you require will be dependant on your own preferences, your home’s location and building characteristics. For more information on heat retention, material choices and glazing, please get in touch with us via a form or simply give us a call. Alternately, keep reading.


Once you’ve found a door that looks great at a reasonable price, there’s one thing left to consider. In the unlikely event of break-in, will it hold up?

We believe burglar-proof (or as close as can be) should be built as basic. That’s why we take part in the British Police project Secured by Design, building our products to their exacting standards, arrived at through years of study and expertise in crime prevention.

Of course, there are always further measures. If you live in an affected area, or simply require greater peace of mind, there are many customisations possible: lock and bolt types, materials and more.

To discuss security concerns, you can get in touch via form or emails – or keep reading here.

A range of styles

A door is a very important part of a home’s overall look. Choosing the right style and material is the difference between a look which simply clicks and one which doesn’t. Not to mention the effect on house prices.

We try to offer the widest range and give sound advice built upon 45 years in the home improvement sector. So, whether it’s a back or a front door, a bifold, French door or a piece to fit a heritage property, we’ll have something for you.

You can find great examples of our range on this site. Or you can get in touch via a form or phone call to be taken through every option.
