“The INTERSET recessed window flashing system for cedar cladding represents a true technological advance. It’s a natural progression on our 45mm batten system, which provides the depth to pull the flashings back to the frameline creating a natural 65mm deep recess.”
Because the windows are recessed to the warmer framing line as opposed to the outer cladding layer as was traditionally the case, the system has a unique thermal benefit.
“The INTERSET system has no outer fixings penetrating the
underlay or going through to the frame so it’s a huge leap for
weathertightness too, which will improve the productivity of cedar and larch facades long term.”
In Europe, recessed windows in timber facades are commonplace. There, the building methodologies are very different to ours, with thicker walls and double battens that have the natural recess our buildings don’t. “This is where the problem has been for our architects, who are trying to achieve the Northern European aesthetic with a very different system of building,” Mark says.
