Pavaflex is an ultra high performance, natural insulation manufactured from sustainable wood fibre. Supplied as an easy to handle insulating batt, Pavaflex provides a simple, sustainable way of delivering excellent levels of both thermal and acoustic insulation for lofts, walls and floors. Being fully breathable, the insulation ensures a building structure is also able to self regulate moisture levels to prevent the formation of interstitial or internal condensation, preventing damp and mould growth and, thereby, safeguarding a healthy living environment.
Pavaflex’s high density (55 Kg/m3) means the batts are self-supporting and not subject to slumping. In addition, they also have high levels of thermal mass, which provides effective insulation against summertime overheating.
With a thermal conductivity of just 0.038 W/mK, heat transfer through the material is minimised, while Pavaflex’s complex non-woven structure also reduces heat loss through convection. Its vapour-open, hygroscopic properties, which enable it to regulate moisture levels, also mean there is no heat loss through dampness.
Simple, natural, non-reacting compounds added to the material provide protection against insects, biological and fungal attack and make it unattractive to vermin. In addition, Pavaflex is CE marked, has a Euroclass E fire protection rating, and is approved for use as loft, wall and ceiling insulation. It is also free from CFCs and VOCs and does not constitute a waste hazard on disposal.
Pavaflex batts are available in lengths of 1.22m and widths of 375mm and 575mm. Thicknesses range from 40mm to 240mm, in 20 mm increments, with a 50mm thick batt also available. Standard thicknesses are 50mm, 80mm, 100mm and 140mm. Batts are easily cut to size with a knife or wood saw. Completely safe to handle, Pavaflex is simple to install, with the batts’ elastic form providing the flexibility to achieve a tight, snug fit while maintaining its size and shape.
Pavaflex is not suitable for use in masonry cavity walls or beneath ground floor slabs.
