Air Tightness Testing North West England.

We have been in the North West quite a bit this week. A memorable test was one Phil did in a village just outside Ormskirk. (photo of the property above). This was a memorable property for two reasons, the first evidenced by the photo. It was a lovely large house set in its own grounds, overlooking the surrounding countryside ”sounds like estate agent speak but it was very nice” The second reason that it was memorable, was the preparation the owner of the property put into getting the property ready for the air test and the obvious attention to detail that must have happened throughout the build. The actual air test didn’t take long at all, as it was evident as soon as the fan went on that it was going to perform very well.
I have talked about attention to detail in a previous blog, but I’m going to mention it again. We have noticed that when we test larger, high end properties, there is considerable attention to detail, especially with the finishes. However, more often than not, this attention to detail is lacking when you look just below the surface. An example of this is often found in the Kitchen, behind the wall units where the wall meets the floor or doesn’t. Custom and practice is to leave a gap at the bottom of the plasterboard, but if its just left like this, then air will escape through the gap. The same thing happens with the penetrations through the plasterboard behind units. We have seen all sorts, such as four inch core drilled holes for the electrician to pull his wires through, or where the plumber has drilled a larger than necessary hole for the sink waste. Its fine doing this but the holes need to be sealed back up once the wire or pipe is in place. Tis is the hidden attention to detail which makes all the difference on air test day.
So back to the house featured. The attention to detail was definitely more than ” skin deep” and it passed the air test without any difficulty, but more importantly it will be energy efficient. Two other benefits of sealing the bottom of the plasterboard where it meets the floor are:
- It keeps dirt and dust out and where there is a carpet fitted it keeps the edge of the carpet clean.
- It keeps the spiders out.
