Aluminium Sliding Doors That Break New Ground

We only offer the very best at Hazlemere and you can’t get much better than a product that has been officially granted an A+ Energy Rating! What are we referring to? Our outstandingly elegant aluminium sliding doors!

Available in 2, 3 or 4 sections, soon after their release a couple of years ago these Sapa Building Systems’ Crown aluminium sliding doors were the first to be granted a Door Set Energy Rating (DSER) of A+ by the British Fenestration Ratings Council (BRFC) and you can’t get a greater seal of approval than that.

To achieve this rating they had to undergo intense testing procedures where they managed to reach a positive energy balance of 10 or more, the standard requirement for the new A+ rating.

An A+ rating was introduced to acknowledge just how far technology has progressed to enable products such as these to reach new heights in terms of energy performance. Possessing such a high standard of energy efficiency will also be beneficial should thermal performance criteria in relation to building regulations be tightened at any point.

Look a little deeper into how the doors are manufactured and you can easily understand how they have managed to raise the bar from the perspective of energy efficiency.

First of all, the frames on all our bespoke Sapa Crown aluminium sliding patio doors are extremely slim which means that more glass can be inserted into them, allowing more exterior light to pass through them. They also contain thermal break technology which reduces the heat transferred from inside to outside and the double glazed units utilised help it achieve an impressive low U-value of 1.4W/m²k.

When fitted in your home, the last thing you will have to worry about is them costing you a fortune in energy costs. Just sit back and admire the views, both of your doors and the scene outside.
