Guidance Notes

• They must never be installed across a window requiring access for escape purposes.
• When used in combination with other opening windows there should be a sufficient cavity between the windows to allow access for cleaning.
• Where a window is treated with a fixed panel or series of fixed panels ventilation holes may need to be drilled to the outside to permit air flow and combat condensation.
