Portal frame areas asked to be included by Council

Postby noki96 » Thu May 16, 2019 11:28 am

Hi,

I am wondering how I would include the portal leg areas in my H1 Compliance Report?

Council have asked the following:
Please address the following: The heat losses associated with the insulation around the portal legs has not been taken into account. (Approx 1200 x 2.4). This space will not fit a R3.2 batt (140mm thick).

My external walls are 140 timber studs and I have R3.2 batts between studs. I am thinking to fit R1.2 50mm thick batts both inside portal cavity and behind portal shown in red in attached detail.
Any help would be most appreciated.

Thanks so much.
