Thermal Performance

Choosing a Thermally Efficient Door

When we choose new white goods one of the first things we look at is the colourful energy rating certificate on the front to ensure we’re making the right choice! So why wouldn’t you consider energy efficiency when choosing a new external door, after all, it is likely that your door is where most of the heat escapes, so, whether it’s your front or back door that you’re looking to replace you should consider choosing an energy-efficient external door.

Rockdoor composite doors boast of various technologies to eliminate draughts from around the glass (a common area of heat loss) and when choosing your door there are a few additional extras you can choose to reduce draughts further making your home safer and warmer!

What Makes a Rockdoor Thermally Efficient?

There are various innovative technologies that we use when manufacturing Rockdoors that make our doors superior to most exterior composite doors.

S Glaze technology isn’t just designed to keep homeowners secure, as the glass is locked into the door draughts are unable to get through the glazing aperture. To put it simply – there is nowhere for the air to go, therefore it cannot escape!

Thermal efficient materials such as PVC-U skins, thermally efficient glass, reinforced frames and Polyurethane foam all work together to achieve the best possible energy ratings.

Clear Backing Glass is another great way to improve the thermal performance of your Rockdoor, as a special coating can be applied to the glass making it even more thermally efficient. Unfortunately, this cannot be applied to textured glass designs, so if you’re really looking to drill down your energy bills – choose clear glass!

Low PVC-U Threshold is just another option that you can choose to help reduce energy bills and achieve that all-important A energy rating!
