Acara Concepts Ltd distribute Pavatex and Hofatex natural, ecological and breathable wood fibre insulation throughout the UK and Ireland. There are products for every application including roof insulation, external wall insulation (EWI), internal wall insulation (IWI), floor insulation and attic insulation.

Do you want to save on energy bills during the winter? Are you looking for natural insulation with no nasty chemicals added to it? Do you want to dramatically reduce the occurrence of condensation and mould growth in your home or workplace? Are you concerned with having a healthy internal micro-climate? Are you insulating a historic home with solid walls? Are you concerned about your home or workplace getting too warm during the hot summer days? Are you bothered about noise from outside or within your own home?

Then Pavatex and Hofatex wood fibre thermal insulation will address all these needs, and more. Wood fibre is an all-encompassing insulation product which does far more than just prevent heat loss from a building envelope. It adds greatly to our quality of life to make a healthy, warm, quiet building with no harmful emissions being emitted into our breathing air.

Did you know that …

  • Many health problems are closely related to the quality of our indoor air?
  • People spend up to 90% of their lives in enclosed spaces?
  • The incidence of allergy related illnesses is increasing every year, particularly in children?
  • Selecting suitable construction materials is vital to improving the quality of our indoor air?



Wood fibre insulation from Pavatex is a totally natural insulation material which very effectively reduces heat loss from the building envelope. This ecological insulation has solutions for external wall insulation (EWI), internal wall insulation (IWI), roof insulation, floor insulation and attic insulation. The timber raw material has lots of CO2 locked up within the product and in addition the manufacturing process creates minimum CO2 emissions due to the factory’s extensive use of green energy. This compares extremely favourably with most man-made insulation which is very energy intensive. Of course a well insulated building will significantly reduce CO2 emissions so Pavatex wood fibre insulation will greatly contribute to the protection of the ozone layer.

Because the wood fibre is totally natural, there is no requirement to wear any protective clothing when fitting it. There are no harmful chemicals or toxins in the insulation so the interior micro-climate will be much healthier.




Breathable insulation refers to the insulation being able to absorb and release water vapour and condensation from within a building so that it is able to escape through the fabric of a building at a controlled rate, and then evaporate. This keeps the structure dry and therefore warmer, so that damaging mould growth and condensation will not be a problem within the building. Because we spend up to 90% of our time indoors much greater consideration must be given to the quality of the air that we breathe for our health and well being. Damp and mouldy buildings are highly considered to contribute to many allergies and other illnesses. If a waterproof insulation is used, the water vapour may get trapped within the structure where it cannot evaporate, and may cause mould growth, dampness and rot as well as damaging the building fabric itself. Vapour-open insulation is particularly essential when insulating historic or older buildings as these were designed to be totally breathable structures and this must be maintained.



We must start to consider our living environment when thinking about our health. Many construction and insulation materials emit formaldehyde and volatile organic compounds (VOCs) and as the temperature rises in a warm house, these emissions also rise and pollute our air. If natural products are used within the building fabric these emissions are greatly reduced and the air we breathe is much cleaner. The healthiest house in Germany is insulated throughout with wood fibre insulation and its VOC and formaldehyde emissions are dramatically below the recommended guidelines.




Most contemporary buildings are being designed to take advantage of natural light and solar gain to reduce energy use. However during the warmer summer days this glazing can make the interior uncomfortably warm so it is good to know that Pavatex ecological wood fibre insulation is the most effective thermal insulation at storing this excess heat for as much as 12 hours before releasing it. This means that the interior is cooler during the day and warmer at night. Timber frame buildings and converted attic spaces also overheat during the summertime as the construction has very little density compared to masonry constructions. Pavatex wood fibre insulation is the densest and very importantly has the highest specific heat capacity (2100 J/kgK) of all insulation materials and these combined add considerable thermal mass to a building. This ensures a much more comfortable and ambient interior atmosphere, all day long and all year long.




Our world is getting noisier and so we strive for peace and calm in our home lives. Because Pavatex natural wood fibre insulation is so dense and of a fibrous nature compared to conventional insulation materials it is much more effective at reducing both airborne sound (e.g. talking, music, road noise) and impact sound (e.g. footstep, moving furniture, rain noise) through walls, roofs, floors and ceilings. Timber and metal framed buildings often lack good soundproofing so the use of wood fibre natural insulation will significantly improve this situation and enhance the occupants’ quality of life.




The best method to insulate a building is to externally insulate the complete building envelope so that thermal bridging will be eliminated. This is in addition to insulating between the studs or rafters, if applicable. Because Pavatex wood fibre comes in the form of a rigid board it can be easily installed to the outside of masonry or stud frame structures to completely insulate all the junctions, and to save the maximum amount of heat energy. A significant amount of heat will escape through un-insulated junctions and this is noticeable in many buildings where there is mould in the corners and around the windows. Of course Pavatex thermal insulation can be installed internally on walls and the roof, if external wall insulation is not possible.




Nobody likes to think of fire but it is important to consider using a material that will create virtually no harmful emissions in such an event. The Pavatex wood fibre insulation board slows down the speed of a fire as the surface just chars. Pavatex wood fibre has Class E flammability and when used alongside plasterboard this system provides an above-standard fire resistance.




Many thermal insulation materials lose their effectiveness over time because they may sag downwards, they may compact, they may deteriorate or they may become wet and wet insulation conducts much more heat. None of these disadvantages will occur with wood fibre insulation as the rigid boards are dense and resilient and so cannot sag or compact and because the insulation is breathable it will allow any water vapour within it to escape so that it dries out. This is unlike many man-made wool type insulation products which can easily absorb the water vapour but struggle to release it again as relative humidity changes. Wood fibre insulation has been used successfully and very effectively throughout Europe for more than 80 years.

There are Pavatex wood fibre stockists located throughout the UK and technical support is readily available both from our own helpful team and from our stockists. Wood fibre insulation is also available in Ireland. Please contact us for more information.
