Title says it all. It's time to fit a window in my single leaf concrete wall. The hole is out of square so I plan to correct this with 100mm treated timber on just 2 sides.
I'm not sure how the sills go in and how do I waterproof the window?
The exterior is cladco roofing sheet metal with L-shaped 90-degree corner trims. The interior of the building will be studwork timber, rigid insulation and plasterboard.
