Roof Insulation

A well insulated ceiling could reduce your homes heat loss by up to 40%

Insultech are your roof insulation experts.

Poor roof insulation is the main cause of your home’s heat losses and gains throughout the year. Up to 40% of your home’s heat can escape through the roof during winter making it difficult and expensive to keep your home warm. Fully insulating your roof cavity slows down the transfer of heat between your living space and the outside world, creating a warmer home in winter and a cooler one in summer.

There are many types of insulation products available in the marketing however Insultech Insulation recommends blown insulation as the best solution for New Zealand homes. Unlike batts or segments, blown insulation fills up all the gaps and cracks often missed by other products. Blown Insulation is effective at fully insulating your roof cavity and preventing future heat losses and gains.

Jet Stream Max is a high performance, Glasswool insulation designed for your roof.

Jet Stream MAX is a super high-performance, non-combustible glasswool designed for injection into timber frame walls. The system creates a thermal, acoustic, and fire-resistant barrier. The product completely fills gaps, voids, and hard-to-reach areas around pipes, electrical wires, and fixtures.

We are often asked questions about Jet Stream MAX Roof Insulation and how it works. Have a look below for answers to our most common questions.

Is Jet Stream MAX Insulation safe?

Jet Stream MAX Roof Insulation is completely safe for the family. It’s made of glasswool insulation which is non-combustible and can act as a fire barrier. The fibre is inert and presents no health or safety risks to you or your family.

What if I already have some roof insulation installed?

It’s quite normal to find some insulation in most roof cavities however usually this poor quality and ineffective. In some situations, it also might have deteriorated over time. In special situations, we can remove old roof insulation but usually, it’s fine to blow Jet Stream MAX on top of whatever is already there. It’s best to have one of our assessors come and visit your property so he can advise on the best course of action.

What does the R-Value mean?

We often get asked about R-values in Jet Stream MAX roof insulation. An R-value is simply a measure of the thermal resistance of an insulation product. The higher the number the better it will retain heat inside your house.

Customer Testimonials

Here's what our customers are saying about Insultech

The heat pump is not running full on all the time. Even on a cold day, we can turn it off during the day and then, when we turn it on again later in the evening, it just heats the house up much quicker. Amazing, wish we had done it years ago.

Debbie B

The comfort levels in my home have improved out of sight. I am thrilled with the results plus Leigh and his team were brilliant. I am 100% satisfied.

The house is easier to heat and not as cold on frosty mornings. Plus, we live on a busy road and now cannot hear the traffic anymore. CosyWall has made a huge difference.
