Pavaflex Woodfibre Insulation

Application – Pavaflex woodfibre insulation slabs are flexible insulation batts that are easy to install between rafters, studs, and joists.

Nice to work with – Pavaflex woodfibre insulation doesn’t irritate the skin like some conventional insulation products on the market. Due to its low thermal conductivity of 0.038, PAVAFLEX prevents energy loss. Cosy heat stays in the house, the energy to heat a property is lowered and costs are noticeably reduced.

High Thermal storage in summer – PAVAFLEX stores heat through the day and releases it later in the cooler night-time hours. Helping on hot days to keep rooms pleasantly cool. Pavaflex is also highly vapour-permeable. Vapour can escape through the building fabric to the outside.

PAVAFLEX insulation materials protect effectively against noise. Made from waste wood Pavaflex insulation promotes a responsible use of natural resources, low energy use and a positive CO2 balance.
