Foam Baffles

A:  Old sash windows do not have any seals, they relied on the wood being manufactured to a snug fit.

Unfortunately over the years they warp or swell, or get painted shut or have bits planed off so they end up rattling and draughty.

Modern materials are expected to retain their shape forever, not needing to be planed or painted and the window sections are extruded with small retaining channels for brush piles to be inserted around the edges of the sashes.

Wind however finds any weak spots!

That’s why when we test our windows in extreme conditions (our windows are installed in the Lands End Hotel and Outer Hebrides) and we find a soft spot, we go on to invent a solution... in this case foam baffles.

Every window of ours is then fitted with these as standard, irrespective of where in the country it’s being installed.
