In their words
The work was carried out quickly and with a minimum of disruption or mess. The wall now feels dry, and warmer to the touch than a similar, untreated stretch of wall. There are also no signs of discolouration or damp patches. We are considering having all our affected walls treated by BreatheTherm.
Struggling for many years with a continually damp wall in a barn conversion with no damp course. BreatheTherm does what it says on the tin. It allows the moisture in the wall to pass through and wick. The result has been a dry wall throughout recent downpours.
The whole BreatheTherm process has been far more straightforward and successful than I could have imagined. I am absolutely thrilled with the result and would have no hesitation recommending BreatheTherm to anyone looking to improve the performance of a traditional property.
