Glazing directly into stone Post questions and find answers on glazing, double glazing, upvc glazing, conservatory glazing, fixtures and fittings etc....

Some of my fixed windows in this 250 year old house are set directly into the stone mullions.

Recent (20 years plus) fixing method has been "Trowelling Mastic", but I am wondering if one of the many different silicone or acrilic sealants would be better.

I also wonder which grade of trowelling mastic would be best.

The stone is "millstone grit"

Thanks

Rob
