Super Insulation can significantly reduce your homes heat loss over standard installations
While there is no official definition of the term Super Insulation, it is generally used when referring to houses with very high insulation R values, airtight construction with a heat recovery ventilation system, triple glazed widows and a minimal back-up heating system.
The concept is not new, in 1977 the “Saskatchewan House” was built by a the Canadian government and the “Leger House” was built in Massachusetts by Eugene Leger. Publicity about these houses influenced other builders, and many Super Insulated houses were built over the next few years.
While it is possible to retrofit New Zealand houses to Super Insulation standard, it is easier to incorporate the required features when building a new house.
In a Super Insulated house the building envelope must be made airtight in order to keep the heat loss in winter (or heat gain in summer) to a minimum. Careful sealing around doors and windows and at all service penetrations is particularly important. The entire building must be continuously insulated to very high insulation R values (R-7.0 for walls and R-10.0 in roofs) with no cold bridges where walls meet foundations, roofing and other walls.
Super Insulated houses need very little additional heating, often only solar heat, waste heat from home appliances and body heat generated by the inhabitants will be sufficient to keep the house comfortable.
Striving to provide the best insulation for a project just makes sense. Aside from the obvious energy savings, costs are further reduced by removing the requirement for a costly heating/cooling system. The house will also have a much smaller carbon footprint and will provide exceptional thermal comfort.
Safe-R Insulation can provide some of the best insulation systems available in New Zealand. We are also proud to be a part of the SuperHome movement and the push to build better homes.
