External Solid Wall Insulation System

External insulation scope is to preserve the thermal mass capacity of CLT panels exposed to internal thermal conditions. It provides a high level of decrement delay that protects the CLT structure. External wall insulation to structural walls can bring about significant emission reductions from the building and make a substantial impact on household energy consumption.

There are several solutions for the external wall finishing.

InnovHousing is mainly focusing on both ventilated facades and on thermal insulation blanket. The two systems have in common the insulation coating that could be made of stone wool fiber or wood fiber whose thickness vary depending on the climate zone.

The ventilated facade is a system for the covering of the facade that allows the formation of an air chamber between the external wall of the building and its cladding. Quick to be installed it allows the use of different types of cladding such as aluminium or wood planks, stone, or any suitable outdoor material.

The main benefits are:


  • energy saving due to the air chamber constantly renewed by convention because the sun heat falls on the cladding and not on the walls
  • acoustic insulation because of the airflow and the use of different materials that break the sound propagation
  • waterproofing because airflow allows dump and humidity easily to evaporateThe thermal insulation blanket is an external wall insulation system (or EWIS) acting as a thermally insulated, protective, decorative exterior cladding. It is directly attached to the insulation layer by means of a mesh layer on which a protected waterproof finishing, usually made of special coating components, is applied to create a highly resistant and solid surface.

    With the following benefits:

  • very low thermal conductivity (0,036 W/mK) • optimal acoustic insulation rate (RW=55db)
  • totally incombustible (A1 Euroclass)
  • zero decay and unlimited stability to ageing
