Specialists set up perimeter sealing systems. These involve machining a small groove into the window beads or the sashes themselves and inserting a brush or silicone seal. This significantly lowers air infiltration while staying undetectable when the window is closed.Professional GlazingConventional double glazing is typically too thick (20mm+) for historic rebates. Professionals use "slim-profile" vacuum glazing or gas-filled units that are as thin as 6mm or 10mm.
