All Masterframe sash windows can be tilted inwards to make cleaning easier and safer. Particularly large sashes cannot be allowed to tilt for cleaning, as the sash is simply too heavy, exceeding the maximum permissible weight to be tilted safely.
Lighter sashes can be heavy but those exceeding the maximum sizes could be dangerous. That’s why uniquely, on every Masterframe window that exceeds the safe size for the standard easy clean, tilt restrictors, we fit a short pair of safety stays.
So if a large window should be accidentally opened, it will remain vertical, unable to damage anyone or anything.
We are the only manufacturer to fit safety stays to oversized sashes.
Although they do not allow for cleaning, they WILL stay upright and prevent accidents.
