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 seting this eco friendly board to a wall built with lime morter and plastered with
Lime plaster, the structure can continue to breath as it should and you will get a up-grade to the thermal performance of your house.Steico Therm is a square edged wood fibre board that has many uses in eco friendly homes. Predominantly sold by Ecomerchant for internal wall insulation, it is can also be used to infil between rafters and joists. We have also had customers scribe the board to fit between odd shaped supporting up-rights of barn conversions and old timber timber framed houses to help with insulating the properties. Whilst this board will not give an exceptional upgrade to thermal properties, adding a 20mm thick board to a 225mm solid wall would give an approximate 25% increase in thermal capacity.
