Luxury houses and energy efficient buildings need to be insulated from the floor up to really perform and if underfloor heating is going to be installed then underslab insulation is mandatory.
Board Thicknesses: 30mm, 40mm & 50mm: Order per m2 online.
Our SANBOARD 30mm, 40mm & 50mm XPS Floor Insulation Boards are the highest density (35 - 37kg/m3) extruded polystyrene insulation boards in South Afrcia making them stand out clearly against competitiors offerings to architects, engineers and home owners.
Having a board density of 35 - 37kg/m3 means our boards:
✔ Compressive strength is 310 - 360 kPa vs 160 - 310 kPa (Competitors)
✔ Water absorbtion is <0.5 % by volume vs <1.0% (Competitors)
✔ Are significantly stronger boards and will last longer
✔ Absorb significantly less water which affects thermal insulation
In simple terms, with a current fire rating of B-s1, d1, in accordance with SANS 53501-1 and such a high density, they better designed than competitors boards for underslab insulation applications.
Without insulation under the slab:
- Floors feel cold all year round
- Heat disappears into the ground
- Energy costs increase
With SANBOARD XPS Floor Insulation Boards:
- Floors stay warmer and more comfortable
- Heat stays inside the home
- Lower long-term electricity costs
