The Coldest Place In New Zealand Thinks Of

having The Correct Insulation Fitted.

Despite the rivalry between Ophir and Ranfurly regarding New Zealand’s coldest town, Knauf Insulation chose the Central Otago settlement of Ophir when they decided to insulate the homes of a resilient community.

Knauf has completed a 12-month project to insulate every single home and most commercial buildings in Ophir from the pub to the church, warming up the lives of the 50 residents of the small town and the thousands of rail trail visitors that pass through every year.

In 1995, Ophir, two hours outside of Dunedin, recorded New Zealand’s coldest temperature of -21.6°C. Residents remember livestock freezing to the ground and prising frozen hens from their perches.

“We would have to cart buckets of water to the toilet to be able to flush because all of the pipes were frozen,” recalls Jack Allen, an Ophir local.

The Pros and Cons of the different types of Wall Insulation

Polyester Materials Insulation Sections:

Higher density sections that are easily squeezed in between studs and are self-supporting without staples or straps. Polyester insulation is moisture resistant.

Fibreglass Wall insulation

This material is low density and is used extensively.

Foil Wall insulation

Was used extensively years ago for reducing radiant heat loss. Its effectiveness is lost when it is tarnished or corroded, collects dust or condensation, gets ripped or damaged. Due to the risk of electrocution in working with a conductive material around electrical wiring – extreme care must be taken with the installation.

Polystyrene Wall Sheets:

These are rigid sections that have been used extensively in the past. The polystyrene must be isolated from wiring for safety as it can be affected by the polystyrene material.
