Polyester Underfloor Insulation Packs


The Best Long-Term Insulation Material for Under Floorboards.

Make your home cosy from the ground up with the most effective insulation and fitting technique.


Why use it...

Around 20% of heat loss can be saved by insulating your floors. This means you'll need less heating and cooling to keep your home at a comfortable temperature, and enjoy a much warmer home.

Insulation is about protecting the inside of the building from the temperature outside and also reduces sound transfer.

Insulation's thermal effectiveness is measured in what is called R value; the higher the R value, the better the insulation. An un-insulated floor rates R0.7.  The addition of carpet and a good quality underlay will only improve this rating to R1.0, which is still an insufficient rating to achieve a comfortable home.

If you have a highly ventilated floor (such as an elevated home that allows air to flow freely) historically, we recommended a two layered solution comprising highest quality polyester at R1.5 plus a thermo reflective insulation blanket. This combination is rated at R2.9.  This combination was very expensive and is no longer necessary as we have a much more cost effective approach.

ecoMaster's premium underfloor insulation is rated at R2.5 which achieves an overall rating of R3.2. This makes a real difference to your comfort, adding real value to your home and can boost your home’s energy star rating by up to 1½ stars. 

What it is...

Polyester insulation is manufactured with consistently high quality, making it the most effective product for insulating under timber floorboards. 

Specially manufactured in rolls, this insulation requires fewer joins and is easier to install than ordinary insulation batts. The robust nature of polyester holds its shape over time, ensuring long-term comfort.   

ecoMaster's unique installation technique sees the material stapled at 10-15cm intervals to ensure it is secure and will not sag over time.  Only polyester's strong, heat-bonded fibres can be secured with staples long term.

How it works...

The cold air beneath your sub-floor permeates the timber to make a cold and uncomfortable floor. The low insulative properties of timber (which is only 19mm thick), combined with possible air leakage, create a heat sink beneath your home, drawing the heat out from below. 

When to use it...

ecoMaster's underfloor insulation is suitable for enclosed and open timber sub-floors.  Regardless of which type of sub-floor type you have, we recommend installing the highest quality polyester insulation.
