Pavatex Pavaflex 375 is a flexible woodfibre insulation slab designed to fit between timbers with 400mm centres.
Pavatex Pavaflex 575 is a flexible woodfibre insulation slab designed to fit between timbers with 600mm centres.
Pavaflex can be used between studs, rafters and floor joists.
The surface of Pavaflex is not suitable for a render or plaster finish.
Key Benefits
Pavaflex wood fibre insulation slabs offer versatile, flexible solutions for insulating between rafters, studs, and joists, making them an ideal choice for wall, floor, and loft insulation projects. These easy-to-install panels are designed to improve energy efficiency and comfort.
Comfortable and Safe to Handle—Unlike some traditional insulations, which can irritate the skin, Pavaflex wood fibre insulation is gentle and safe, providing a more user-friendly installation experience.
Enhanced Winter Thermal Protection – With a low thermal conductivity of 0.038, Pavaflex effectively minimises heat loss, helping to retain cosy warmth inside the home. This energy-efficient insulation reduces heating costs significantly.
High Thermal Storage for Year-Round Comfort – Thanks to its dense structure, Pavaflex excels in both summer and winter. Its high thermal storage capacity allows it to absorb heat during the day and release it at night, keeping indoor temperatures stable and comfortable during hot days.
Breathable and Moisture-Resistant – Pavaflex's high vapour permeability ensures moisture can escape from the building fabric, preventing damage caused by trapped dampness. It contributes to healthier, more durable constructions.
Superior Sound Insulation – Due to its dense, porous fibre structure, Pavaflex provides excellent noise insulation, blocking external sounds and creating a peaceful indoor environment.
Eco-Friendly and Sustainable – Manufactured from reclaimed wood waste, Pavaflex promotes responsible resource use. Its natural components enhance recyclability, composting, and energy recovery at the end of its lifespan, supporting environmentally conscious building practices.
Application
Warm Roof – Friction fit between rafters
Walls – Fitted vertically between studs
Suspended Floor & Cold Roof – Can be used between joists, laying horizontally for loft insulation, or between rafters for insulating suspended floors.
