MONO RT+ single glazing

A unique system for replacing single glazing on period properties. It’s so good, it’s recommended by planning authorities in even the most sensitive conservation areas.

MONO RT+ fits into even the narrowest window rebates, so it’s ideal for Georgian properties. It’s lightweight enough to allow the sash mechanisms to be retained, too. And even though it looks like the original glass, it reduces heat-loss and therefore cuts energy bills.

Profile of Mono RT+

MONO RT+ is supplied as a 4mm pane of genuine hand-drawn glass, suiting the aesthetic of the period. It has no edge seals and is installed in much the same way as conventional single glazing.
