Butyl Glazing Compound is specially formulated for glazing double glazed units into timber window frames where a timber bead is to be used. Suitable for both soft and hardwood frames. Its elastic formulation moves with the frame, making it easier to apply than most competitive putties. It has an extended shelf life, and the added plasticiser improves adhesion and helps prevent cracking. Suitable for use with laminated/heat absorbing glass. Also ideal for bedding insulated glass units and glazing greenhouses (metal and timber). Unsuitable for plastic frames, or frames treated with decorative microporous stains. Volume: 2kg.
