Some brief information on Internal Wall Insulation
Where External insulation is not possible for various reasons such as cost or complexity, internal wall insulation is the next best alternative. The most common type of Internal wall insulation is also known as dry lining. In this process, the internal walls have insulation boards applied to them. A good idea is to include an airtightness membrane before mounting the insulation boards.

It should be mentioned, however, at this stage that depending on the type of house involved different materials such as glass fibre rolls can be used as an alternative to dry lining.

  • Less time to complete than external insulation
