Window Opening In Cavity Wall 

Many thanks

Yes you can, the following web site/page shows the various products and details web www.arcbuildingsolutions.co.uk/products/insulated-dpc/

@@eldonanimation great, I always wondered why it's not commonly done. Thanks.

​@@bilpat5123Well it is commonly done with window formers. It's the most common practice going 😂😂

In the UK it is a National House Building Council (NHBC) requirement to apply a damp proof course (DPC) over each lintel to protect it, this allows any water that gets into the cavity to transfer across the sloping face of the lintel on the DPC and be released externally via weep holes. The DPC is turned up at the ends to ensure the water is not directed into the cavity. Hope this helps

I use Blender
