The L type windpost is a cost effective structural system designed to suit each and every individual project. The posts build into the internal skin of blockwork and bolt to the structure via suitable fixings.
The use of WPT1 clip on ties to the external leaf & WPT2 clip in ties to the inner leaf, therefore transferring the loadings applied to the cladding back to the structure.

The following tables illustrate the typical sizes available, however, almost any size can be designed / manufactured.
Windposts are designed as simply supported beams. Maximum deflection is height/360 and maximum stress is 191N/mm2
