Thermofloc is a natural floor insulation. Made from cellulose that has added minerals to make it fire retardant. It is simple to install and is much more affordable than any other natural insulation we found.

Installation

double whisk mixer

To break apart the insulation blocks we used a double whisk mortar mixer. By using an online calculator to work out how much we needed for our floor dimensions, we could be sure to achieve the correct density and therefore U-value.

Properties

NaturePlus – Thermofloc is the first cellulose insulation to be awarded the coveted NaturePlus mark of quality and sustainability.

  • Laid density of 40kg/m3
  • Thermal conductivity 0.039W/mK
  • Fire classification as per EN13501-1
  • Free of hazardous substances as defined by ETA-05-0186

Assessments show Thermofloc does not provide a suitable habitat for rodents and as such rodents will avoid nesting within the insulation.
