Where in the house will the fresh air be supplied from and exhausted?
The supply and exhaust vents should be located at 3 m apart. This is to ensure that the exhausted air is not reutilised. There are 3 options (i) use roof vents and have the roofer install them. They are G5 (150mm) roof vents. (ii) Have the extract and supply come through grilles on the soffitt (iii) Go through holes in the gable again using grilles on the outside. The most common setup is to use roof vents generally on the rear of the house. Contact us before roofing starts and we will arrange delivery of roof vents.
