Glazing Sealant is used to seal glass into frames of either windows or doors. It has been used since the 17th Century, when Glazing Putty made from chalk and linseed oil was first used to seal windows. Eventually, oil-based caulks were used, but by the 1920s Polymers were being developed and by the 1960s, polymer-based sealants had become the most popular product available. It remains the most popular type to this day.

Dow Corning 796 is suitable for sealing – against weather – between glass and various types of window and door frame, including wooden, aluminium and PVCu.

Dow Corning 799 contains a fungicide that helps to prevent mould from growing in areas that are particularly susceptible to warm, but damp, temperatures, for example bathrooms.
