SupaSoft Insulation – Thermafleece Polyester Recycled Bottle Wool – 50mm & 100mm – PSS50390

Thermafleece SupaSoft polyester insulation is the perfect choice for insulating your campervan conversion. It has a great R-value to cost ratio (R = 1.25), and it’s easy to pack into hard to reach areas. Either use it in combination with a PIR insulation board, or use it as your standalone insulation material.

Polyester wool is also one of the lightest insulation materials available, making it a great choice for campervans where weight is at a premium. It is also totally safe to handle, making it a great alternative to rockwool and fibre-glass insulation.

We used SupaSoft loose fill polyester wool in our own campervan conversion. If you’re not sure how to insulate your van, check out our article – Insulating a van conversion.

Please note: the dimensions stated in the specifications for this product are the shipping dimensions for rolls of insulation. The unrolled dimensions will be as specified in the dropdown menu above.
