Steico Therm Internal is a T&G edged wood fibre board that has many uses in eco friendly homes. Predominantly sold by Ecomerchant for internal wall insulation, it is used to fit on to rafters, joists and studs.  

This insulation material is water vapour open, which means that water moisture can pass through it without hinderance. If you have a house built with lime mortar, this can be a critical factor in deciding which insulating materials you need to use to insulate your house. With most houses built before 1920, builders relied on the heat within the house to force any excess moisture to the outside. Lime is breathable so the moisture would breath out through the walls. If you apply something like polystyrene to the inside wall of this type of house, then moisture could become trapped and start causing the likes of mold and mildew.  By correctly setting this eco friendly board to a wall built with lime mortar and plastered with Lime plaster, the structure can continue to breath as it should and you will get a upgrade to the thermal performance of your house.

Features:

  • - Steico Therm has high compression strength
  • - Steico Therm has high heat protection during summer months (absorbs heat from the sun and give it off when it gets cooler)
  • - Steico Therm has excellent insulation qualities
  • - Steico Therm is water vapour open
  • - Steico Therm helps to regulate the indoor climate, due to the long phase shift so helps with summer heat protection as well as winter heating.
  • - Steico Therm is an eco friendly insualtion board
  • - Steico Therm rigid insulation board is recyclable
  • - Steico Therm is an accredited heat insulation material

Material:

  • - Wood fibre insulation board produced in accordance with EN 13171 with ongoing quality supervision
