Sub-Floor Insulation
In Australia, a a new Energy Rating system is now in place for all new homes. Up until June 30 2005, new homes must certify to at least 4-Star level and include solar heated-water or a water-recycling system. After June 30 2005, all new homes must achive 5-Star rating minimum to be given a Building Permit.
Our home is certified for 4-Stars. To achieve this, we needed some sub-floor insulation. We have fitted R2 polyester batts. To fit these, one method is to gather-up a section of the batt and staple it to the joist. We have chosen to run packing-case tapes under the joists, attached with staples. I think this is better for servicability, as the batts can be readliy removed/replaced, although it is quite a tedious job running the tapes under the joists -- we should have run them after the bearers were done amd left them un the ground until the joists were in place.
