Optimised rib system for high load-bearing capacity
Verified compatibility with conventional glazing sealants (based on polysulphide, polyurethane and silicone)
Ventilation channel for vapour pressure compensation (from 32 mm block width and 2 mm thickness upwards)
Glazing must be packed in such a way that the glass edges are not overstrained. The glass edges must not touch the frame at any point. The installation position and number of glazing blocks should comply with glazing trade technical guideline no. 3 "Packing glazing units".
Arrangement of blocks
Blocks should be positioned about one block length from the corners of the glazing units. The distance can be reduced to 20 mm in some cases if the risk of glass breakage is not increased by the frame and the position of the block. Blocks can be positioned about 250 mm from the corners of very wide, fixed glazing units. Glazing blocks must be positioned over a frame fastening point. The number of glazing blocks should be increased accordingly for heavy glazing units.
