Achieving very high airtightness levels (< 0.6 ACH @ 50 Pa) needed to make a super efficient house is critical, and we helped Ed achieve his airtightness goals though periodic testing during the construction phase.

Ed also wanted to use low embodied energy products. Because Passive Houses require significantly more insulation, it was important toEd to lower the energy ‘foot print’ the insulation types he chose had on the environment. For that reason, Edchose cellulose insulation, manufactured in Etobicoke Ontario to ‘dense pack’ the rafter cavities (see photo), and relied on the expertise we had on dense packing techniques.
