Charred timber cladding profiles
Compare Inflamed profiles, their available sizes and fixing principles. The shadow-gap half-lap is our recommended standard cladding solution; tongue-and-groove and bespoke profiles are available on request.
4 profiles shown
Recommended standardShadow-gap half-lap (Z half-lap)
Inflamed's recommended standard exterior cladding profile. The half-lap creates a closed joint with a crisp shadow line, suited to ventilated rainscreen façades.

Wall build-ups
Construction details
Review typical ventilated cladding build-ups and download information to support design development. Final build-ups, membranes, fixings and substructure requirements must always be confirmed for the individual project.
Interactive ventilated wall breakdown
Select a layer to see its function. Switch between vertical and horizontal half-lap cladding.
Board orientation
Vertical cladding requires a double-batten substructure. Install the first battens vertically over the breather membrane to create a continuous drainage and ventilation cavity. Fix horizontal counter-battens over the vertical battens, then fix the vertical cladding boards to the horizontal counter-battens.
This diagram shows the general ventilated construction principle. Final batten dimensions, fixing centres, membranes, flashings and structural fixings must be confirmed for the selected profile, building design and local regulations.
This guidance does not replace project-specific engineering or architectural advice. The final façade build-up must be confirmed by the project's architect, engineer or qualified installer.
Vertical half-lap cladding
Double-batten substructure: vertical battens over the breather membrane form the ventilated cavity, horizontal counter-battens carry the vertical boards.
Technical drawing in preparation – request this detail
Request construction detail →Horizontal half-lap cladding
Horizontal boards fixed directly to vertical battens over the breather membrane; the battens form a continuous ventilated and drained cavity.
Technical drawing in preparation – request this detail
Request construction detail →Vertical PAR open-joint cladding
Open-joint construction with a black UV-resistant façade membrane visible through the joints. Distinct from closed-joint half-lap or tongue-and-groove construction. Project-specific – confirmation required.
Technical drawing in preparation – request this detail
Request construction detail →Interior wall cladding
Interior lining build-up. Substrate, battens and fixing depend on the wall and the project fire strategy. Project-specific – confirmation required.
