Pavatherm is a high-performance pressure-resistant, vapour permeable, natural and ecological thermal insulation board based on wood fibre. The Pavatherm boards are universal and multifunctional suitable in the roof, the wall, the facade and the floor. The high thermal performance and heat accumulating capacity together with the convenient size, makes the Pavatherm board the ideal solution.

Pavatherm wood fibre Insulation Boards – high compressive strength board, can be applied on a Cross Laminated Timber (CLT) Structure, timber/Steel frame with an external OSB/Ply layer or on existing masonry structure to receive cladding battens (no brackets required).

Pavatherm Applications:

Roof – Over or under rafter with base (PLY/OSB).
Wall – On to CLT, studs with base or existing masonry.
Floor – Between or under joists with a base.

For all the external applications the Pavatherm boards must be protected by appropriate Pavatex primary external boards or breathable membrane.

Finishes: Subject to primary boards and application
Fixed: Subject to primary boards and application

Please see variations for Pavatherm board sizes and details.

Thermal insulation both in summer and in winter

One advantage that is particularly noticeable in winter: thanks to the woodfibre, the home retains its comfortable warmth for a long time, because the extraordinary thermal-insulating characteristics of woodfibre materials avoid heat loss. The natural porosity and the composition of the fibres make the wood a particularly effective insulator.

Thanks to the woodfibre you can enjoy a mild temperature even on hot days. The attics in fact tend to heat up a lot in summer because the roof captures the warmth of the sun on a very large surface. Woodfibre board products have a higher weight than, for example, glass wool and can offer greater resistance to solar radiation (greater heat storage capacity). The daytime heat is then released only in the evening hours, cooler.
