About TIMBER FRAME RENDER

As described in the EWI section, Timber frame construction is increasingly common in the UK market. The timber structure options tend to be either a timber structure with insulation placed within the timber stud or SIPS (Structural Insulated Panel System). Both systems provide efficient sustainable construction methods. Thin-coat rendered finish to timber frames is particularly suitable and cost efficient. The process involves the use of a render system approved Cementitious Render Board (this can be non-combustible) applied to timber battens. The thin coat reinforced render system is applied directly. The full range of render finishes are available. Note: brick clips may increase the loadings and may need to be considered by the structural engineer.
Structural Insulated Panels (SIPs)
SIPS Panels provide an extremely fast build option for contractors, developers and home-builders.
The section through picture here demonstrates a typical build up when render is the chosen finish.
Typical render board fixed to timber framework
Typical external grade render board by Knauf. Installation guidelines for render board a crucial element and base for render. Correct specification and application are vital. Thin coat renders are directly applied. Render system application guidelines apply.

THERMAL PERFORMANCE
Timber frames offer a more sustainable method of construction. This method of construction is also popular in the development of Passivhaus projects.
