Pre DIY isotherm installer checklist
The nice thing about installing isotherm eco-friendly insulation, is that the product comes in two sizes. So depending on your beam width, you can order the appropriate size isotherm for your diy installation. You also do not need a dust mask. For fibers flying around like with think pink aerolite (although wearing a dust mask for dust is still advised)
- Measuring tape
- Step ladder
- Portable light
- Industrial scissors
Measure up for the diy isotherm install
Do a measurement of you home and make sure you have enough insulation for the diy isotherm install. Always take an outside measurement of your home. As there will be wastage or overlaps as we like to call it. Once you have the final measurement then add on an extra 8% – 10% for overlaps.
Why do you need extra isotherm for overlaps?
As mentioned earlier isotherm comes in two sizes. Generally the 750mm wide size is used when installing isotherm in a home. The average beam distance is around 700mm wide. The reason it comes 50mm wider than needed is so that you reach from beam to beam comfortably. Tucking it in on either side leaving no gaps in the diy isotherm install.
Make sure you don’t compress the product once you have removed it from the plastic. Isotherm will slowly un-compress itself while you are installing it. You want to make sure nothing is compressing it after installation. By compressing isotherm it restricts its ability to insulate properly. Small air gaps in the isotherm is what traps heat and makes the insulation a good product to install.
How to cut isotherm insulation
If you are doing a diy isotherm installation, then at some point you are going wonder how to cut insulation. You don’t use a saw like you do with think pink aerolite, we use industrial scissors to cut isotherm insulation. You will find that it is a really hard product to cut through. It can be done quite comfortably with the right kind of scissors.
How to install isotherm insulation
Once you have removed the product from the plastic. It is already cut to size. You need to roll the isotherm out along the ceiling and in between the beams. Be careful of down lights and wires in your roof. Make sure to fill up the whole beam width without leaving any gaps. All the wires in the roof need to sit on top of the isotherm. So that they are accessible at a later stage if you need access to them. This is the most difficult part of doing a diy isotherm installation. Its why we do recommend getting it installed by insulation experts.
Cut holes around down lights – DIY isotherm
This part of the diy isotherm install is extremely important! Please make sure you have checked and double checked that you have cut holes around all of your down lights. Down lights create heat, so you want the heat to be able to escape through the isotherm insulation.
DIY isotherm – Don’t forget the trapdoor
Furthermore, after you have finished the installation. Make sure you have a piece of isotherm insulation left over to stick on top of your trapdoor. Generally you don’t need to glue it down. You can make it fit snuggly between the trap door square shaped battens
