Internal Wall Insulation


Climate Internal Wall Insulation (IWI) is our grey, enhanced thermal performance, EPS insulation board for use with plasterboard as an internal wall insulation.

Internally insulated walls are significantly less expensive compared to external wall insulation systems and require no maintenance. The same energy savings are achieved with internal and external insulation, consideration to the benefits and undesirable effects of each during installation should be considered when deciding which application is best suited.

Insulating internally to an existing solid masonry wall offers excellent energy savings and also creates a higher level of comfort. Internal wall insulation reduces internal heat being lost into the wall, warming the room before heating up the outside walls. Installing new insulation and plasterboard to the inside of an old building will also reduce coldness from drafts.

Details of our Climate Internal Wall Insulation Boards can be found on our Technical Datasheet below.
