Air-tightness

In our opinion air-tightness is the most important of all the guiding principals of energy efficient construction.  Over the last 10 years we have developed and tested methods of addressing air-tightness in our building and to date our best result has been an exceptionally low 0.22m3/h/m2@50pa ourselves and the clients are very proud of this result. 
We are keen to make air-tightness cost effective and work hard to build these measures into the building fabric and try were possible to avoid costly tapes and fabrics.
