How a prefab home can keep you warmer this winter

by geniushomes

The South Island of New Zealand can get some pretty cold weather. According to Niwa, Ranfurly and Middlemarch regions in Central Otago tied for New Zealand's coldest temp of 2018 at -6C. This is by no means the coldest temperature recorded in the South Island. That accolade goes to Ranfurly, Eweburn which recorded a staggering –25.6 on the 17th July 1903.

The team at Genius Homes are based in Timaru so they know a thing or two about the cold, and this has led them to build homes that are well set-up to fight the plunging temperatures. And they ensure each home they build is well insulated to fight off the freeze.

Insulation has an R value, which is its rating on the material's resistance to conductive heat flow, indicates insulating effectiveness. The higher the R value the better that material will be at keeping your home nice and warm.

The New Zealand government has a set of standards that outline the minimum R value for insulation in new build houses. But the value they require is for the area, and all the materials combined and the total R value achieved.

Let's take your roof as an example. To meet the building regulations you need to have an insulation level of R3.3 to meet building standards.

 One of the many materials Genius use is pink batts.

For a pitched timber frame roof with corrugated iron cladding, 90mm bottom chord and chord spacing of 900mm you're looking at insulation rated at R3.5 to achieve the government's requirement of R3.3

A skillion roof (concrete tiles) with 190mm rafters and battens and rafter spacing of 900mm would require insulation with a rating of R3.1 to achieve an overall R rating of R3.3.

Each Genius Homes design has a standard inclusion of R3.6 Badford Gold roof insulation, which combined with the Colorsteel roof sheeting and pine roof framing makes for a higher than standard level of insulation.

Genius Homes carries this philosophy of warm houses even further as each home includes a Mitsubishi heatpump, with some homes featuring a wood burner too.

There are other advantages to choosing a Genius Homes prefabricated home beyond the next level insulation and heating levels.

Factory built means that building is done in dry conditions, so no surprise showers or dumping of snow on your framework before the house is weathertight! Seals are nice and tight locking in more heat.
