Apeer CEO Asa McGillian shows the difference between an Apeer70mm Door and a hollow monocoque door.

Apeer 70mm doors are proven to be nearly 7 times more thermally resistant than the alternative hollow monocoque doors.

Apeer 70mm doors are A++ Rated and proven to be nearly 7 times better at keeping heat in your home, and money in your pocket.

With home heating energy prices skyrocketing, Apeer 70mm is a door for the times we’re living through. No matter how we heat our homes – gas, electricity or oil – it’s costing us all a lot more. At Apeer our doors are nearly 7 times more thermally resistant than alternative hollow monocoque doors.

New World Developments

An Apeer 70mm door outperforms a hollow monocoque door.

In order to demonstrate the superior thermal resistance of Apeer doors compared to our competitors, we engaged the renowned European testing certifier TÜV Rheinland, to conduct rigorous thermal testing. The results unequivocally confirm that all Apeer 70mm doors significantly outperform alternative options like hollow monocoque doors by nearly 7 times.

This substantial enhancement not only ensures a more comfortable and cosy environment but also translates into real savings on your annual heating bills.
