Hemplith® Flex

The flexible hemp-fibre insulation batt.

Hemplith® Flex is a flexible insulation batt of 85% hemp fibres and 15% support fibres — for thermal and sound insulation in infills, roof, wall and drywall.

The batt is friction-fitted seamlessly between rafters or studs with about 1 cm oversize and additionally fixed if needed — for tight, gap-free insulation.

As a vapour-open natural material, Flex regulates moisture, creates a pleasant indoor climate and is recyclable.
