Hope in the Air – l’espoir dans l’air

The scaffolding is down and the pergola is on its way to being finished – it has been a busy week on site!  The building is beginning to look like the original concept sketches that Tom did almost a year ago.

We only have a week left in France before we head back to the UK.  There are still a few things that we need to sort before we go because we will not be back until Easter.  It is hard to choose tiles and flooring when you are not around to see them in the shop.  Still, this as finally been decided as has our hedging, decking and walling!

We have an air tightness test booked for next week as well.  Achieving a good level of air tightness is important for the energy efficiency of the building.  The benefits of improved insulation and more energy efficient heating systems are lost if warm air can leak out of the building and cold air can leak in. Too much air leakage can lead to unnecessary heat loss and possible discomfort in the house which you would feel as draughts. The test involves regulating air pressure inside the house.  They do this by fitting a temporary airtight screen to our front door.  They then mount a big fan to the screen which blows air in to and out of our house so that they can create a pressure difference between the inside and outside of 50 Pascals.  There is then some more complicated maths to do. To pass an air leakage test in England and Wales, a home must achieve an air permeability result of 10 m3/(h.m2).  We hoped to achieve 3 m3/(h.m2)! We’ll let you know how it goes.
