Floor Insulation

Floor insulation can reduce your homes energy loss by up to 15%

Under Floor Insulation Specialists

About 10-14% of heat loss from an average home is lost through the ground floor. If your floor isn’t already insulated, this could also be a good move to help you cut your energy bills.

Traditionally underfloor insulation has been a bit of a luxury in New Zealand but this is an important part of your home’s thermal barrier. In most newer homes underfloor insulation is taken care of as part of the slab design, however for older homes without underfloor insulation, polyester insulation blankets are a great solution.

Insultech Insulation recommends polyester blankets for underfloor insulation because of their effectiveness and ease of install. They are also a great solution for insulating your home’s mid floors.

Introducing Ployester Insulation Blankets

Polyester fibre underfloor insulation blankets are manufactured specifically for placing between floor joists, against the underside of the floor. Our floor insulation blankets have superior strength in both directions compared to some other typical polyester floor blankets or batting. The rolls are uniquely sized to facilitate handling in confined sub-floor spaces and can be torn readily to suit joist length providing great installed insulation R-values.

It’s always easier to use polyester blanket insulation for your floors rather than sheet or segment style insulation. Polyesters typically also have the advantage of having a slightly higher installed R-value than polystyrene – the higher the R-value, the greater the insulator’s effectiveness.

Frequently Asked Questions

We are often asked questions about under-floor insulation and how it works. Have a look below for answers to our most common questions.

Are polyester insulation blankets safe?

Our products are made from a non-hazardous material and is completely safe for the family! The rolls don’t absorb moisture (less than 2% over 96 hours), which is important if your location is anywhere near the coast (most of N.Z.). Any moisture absorption can result in performance reduction, product deterioration, and other associated health risks.

The blankets are installed hard against the floor to stop rodents living in a cavity, which is often created by other types of floor insulation eg Foil. While polyester is regarded as a combustible product, our products contain a flame retardant additive to reduce the risk of fires.

How long will Warmafloor Insulation last for?

Polyester Insulation blankets have a 50-year durability rating. Installing insulation blankets under your floor is a one-off investment that will likely last you for the life of the property.

What does the R-Value mean?

We often get asked about R-values for polyester insulation blankets. 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.

Uninsulated floors have a thermal resistance of R0.6, which can be improved to R1.6 or R1.8 with the blanket system correctly fixed against the floor. It also reduces draughts through gaps between uncovered timber strip floors.

How long does it take to install?

In most cases, polyester insulation blankets can be installed in a single day however this does depend on the size and complexity of your house. Just head away for a day and when you come back your floors will be completely insulated. You’ll notice the difference straight away and we know you’ll love living with insulated floors.

Will Warmafloor Insulation save me money?

An uninsulated house is hard to heat in the winter and difficult to cool in the summer. By insulating your walls, roof, and floors you’re helping complete your home’s thermal envelope. This will effectively help to trap inside the home, making it easier to heat and cool all year round. This means you won’t need to put as much effort into trying to heat the home up or cool it down which is a large part of your energy bills.

Underfloor insulation helps complete your home’s thermal barrier and will help to reduce your home’s energy usage.
