Timber frame wall lining

Celotex offers two solutions for single timber frame wall lining applications.

Timber frame wall sheathing

It is now widely recognised that, in highly insulated framed structures, the thermal bridging effect of the timber frame itself becomes significant.

The first utilises the low lambda values of Celotex GA4000 and Celotex XR4000 between the studs, followed by an internal lining of Celotex TB4000 over the studs. This solution provides for the thinnest build-up with the better thermal insulation.

Use Celotex TB4000 and Celotex GA4000 high performance thermal insulation in timber frame wall applications to minimise insulation thickness and give the following benefits:

Offers the thinnest solution available

Provides reliable long term energy savings for buildings

Low emissivity foil facers give improved thermal insulation with cavity air spaces

Reduces thermal bridges through studs and rails, when used in a two-layer system

Provides cavity for services

The second option is to use mineral wool batts fitted between the studs, followed by an internal lining of Celotex TB4000 over the studs.

This solution gives a thicker build-up but offers improved acoustic insulation.

Steel stud framed wall insulation

Historically, the use of steel framed walls has been found mostly in the construction of commercial buildings.

Use Celotex TB4000 or Celotex GA4000 high performance thermal insulation in steel stud framed wall applications to minimise insulation thickness and give the following benefits:

Ideal for lightweight, steel framed commercial and industrial buildings

Provides reliable long term energy savings for buildings

Low emissivity foil facer gives improved thermal insulation with cavity air spaces
