Why have we created Flat 51?

We believe in comfort and we know in energy efficient homes that the issues of poor indoor air quality and overheating are becoming of increasing concern.  Flat 51 is a chance for everyone to understand how we can deliver this effectively – and the reasons why. 
Flat 51 is our very own ‘feel room’ – you can experience how we create the best indoor climates for homes.

‘We spend 70% of our time within 4 walls – the air we breathe and the way we feel should be our number one home comfort’

Comfort with a Capital C.

Flat 51 and our comfort concept isn’t just based on our own experiences and assumptions – it’s based on science to.
When you visit we will explain and you will feel how you can’t deliver comfort by managing temperature alone and why our magic number is 10.5
