Rigid PIR Insulation boards above between and below rafters at pitch roof level

Application - Internal Partition & Interior of External Walls

Interior Stud Partition and Internal Solid Wall Insulation ...

including between Metal and Wooden Studs, and Solid Wall Cladding

The insulation of interior walls is a fairly simple process, with the main considerations being the resultant effect of soundproofing, space requirements and cost.

A variety of plasterboards, application specific wallboards, and insulated wallboards exist. The application of these boards is all very similar, whether using plaster-dab or mechanical fixing methods.

To keep the thickness of internal walls to a minimum, and in specific cases such as the insulation of kitchen and bathroom walls higher specification insulation boards may be required.

Insulation considerations will normally swing towards acoustic performance rather than thermal, so in normal partition walls Semi-Rigid Mineral Wool will be the most effective and most cost effective choice.

In cases where there are extreme soundproofing challenges, particularly from impact noise, an Acoustic Membrane, or a product combining a membrane with rigid boards may be required.

Products to combat challenging acoustic difficulties are manufactured by Cellecta, and to a lesser extent, Karma.

The brief examples above are indicative of the build-up of interior wall insulation solutions. Internal spacial considerations may apply.

In apartment blocks, and certain other property types, acoustic values requirements that are required by Building Control will dictate the wall design choice.
