How to Insulate Your Loft Floor Without Using Fibreglass
This How-To Guide will display how to insulate your loft floor, without the use of Mineral Wool or Fibreglass.
The insulation included in the Loft Floor Insulation Kit is EcoQuilt Expert. This product is a 15mm, 6 Layer Multifoil with highly reflective foil layers. The product is thin, flexible, easy to install and does not contain any harmful fibres. EcoQuilt Expert is equivalent to approx 100mm of Mineral Wool while only being 6mm when compressed
The How-To-Guide is based on a single layer of EcoQuilt Expert. If you wish to proceed with the double layer option, please view the How-To Video for further information.

Remove Existing Minerlal Wool Insulation
Start by removing the existing loft insulation. Ensure a mask and protective clothing is used to avoid irritation to the skin.
Installing first run of EcoQuilt
Measure out the length of material required, then roll our EcoQuilt Expert over the joists. EcoQuilt can be simply be cut using scissors or a cutting knife - Both available in our Multifoil Fitting Kit. Ensure when the second run of EcoQuilt is installed the layers are overlapped by 50mm.
Recess and Staple EcoQuilt
Staple EcoQuilt on both the top of the joists, and also on the sides when recessing. We recommend the use of a 25mm batten to use as a template, this will ensure accurate and correct air gaps throughout the floor area. The benefit of recessing is to create a cavity without the use of a batten. When a cavity is formed, optimum performance is gained from the insulation as this will reflect properly.
Taping & Sealing
Ensure all overlaps are fully taped and sealed using Thermaseal Foil Tape (Provided in the kit) Ensure the brick walls are dust and debris free. Fully tape and seal around the perimeter with Thermaseal Tape. This will ensure EcoQuilt works as an Insulating Vapour Control Layer. It will avoid any air leakages, and keep the heat on the internal.
Install Second Layer
You then have the option to install a 2nd layer of EcoQuilt taut over the joists, Using an additional layer will maximise the heat retention. For further installation benefits, use a 25mm batten over the joists.
Installing Loft Boards
Once 1 Layer of EcoQuilt is installed and taped using ThermaSeal Foil Tape, you are now ready for the installation of loft boards. This can be screwed directly into the joists through the insulation.
