What is the best insulation material for a house?
The ideal insulation material for use as part of this system is Thermo Hemp Combi Jute a natural, breathable and high performance insulation with hygroscopic properties that allows moisture to be released gradually, helping to offset the risk of condensation within the insulation layer. Thermo Hemp Combi Jute is flexible enough to be packed tightly between the joists and can be cut to size easily on site (figure 10). The high density of the material offsets any risk of slumping over time and the lack of proteins in its natural fibres ensure it is not attractive to insects as a food source. Another alternative is wood fibre insulation, such as Gutex Thermoflex, which also offers a dense material with hygroscopic properties.
How much insulation do I need for a 50 x 1.5 floor?

What is Pro Clima Solitex Plus?
The system begins with the installation of Pro Clima Solitex Plus, a windtight breathable membrane that inhibits heat loss while allowing any residual moisture within the joists to disperse, thereby preventing the risk of damp, mould and rot. The membrane is draped up and over the joists to create a cradle to support the insulation material and has sufficient strength to do this throughout the service life of the installation with no risk of sagging (figure 9).
How thick is jute insulation?
Standard thickness that we stock include 60mm, 100mm and 140mm in 370mm wide and 40mm, 60mm, 100mm in 580mm wide. We’re able to use a combination of these thickness to make up the total thickness required. The thickness of the insulation required is normally determined by the height of the floor joists, so if the height of the floor joist is 160mm, then we would recommend using 160mm of Thermo Hemp Combi Jute insulation to fully-fill the void. The total thickness could be a combination of 100mm and 60mm thicknesses on top of each other. For details on the other natural fibre insulations we supply, please refer to our Flexible Insulation category page.

Now, the free movement of air in the ventilated area between the ground and the floorboards ensured the timbers were not degraded in this way.
