What is a WP2 windpost?

WP2 Windposts – An angle system that sits within the inner leaf brickwork and is tied to the inner leaf with 100mm long wall ties. The angle is also tied to the outer leaf brickwork with longer wall ties. The angle is fixed at the base and top with brackets and cleats.

You can CONFIGURE ONLINE a WP2 windpost (150x90x10) section. Below is an explanation of how to use our online configurator with various tips for each stage.

The top connection will be a choice of fitting to attach to Timber, Steel or Concrete beam. You may also download our PDF Installation guide.

Step 1 – Select your top connection bracket. Once the top bracket is fixed in to place, the remaining stem can either be built in to your inner skin, or cut off on site with a disc cutter and the cut end treated with cold zinc spray which can be purchased online. The various options are shown on screen and click NEXT once you have made your selection.

Step 2 – You will decide on the length of the stem you will need. 2m to 3m stems come as one piece. Whereas, 4.0m+ options are two or three stems with a collar bracket connections. The collar bracket and bolts are supplied as part of the kit when you select these lengths and the stems are pre-dilled by UKLintels before delivery.

Step 3 – select your base connection. WP2 windposts are built within the inner wall and therefore the WP2 system has only one base connection offering. Select the below base connections for your windpost and click next. The below sketch shows the stem installed to a 100mm wide inner skin. The baseplate will sit within the cavity as shown.

Step 4 – Various extension plates are also available to suit your specific project. This is because you may wish to have a longer plate for your top connection cleat than our standard 150mm long T1 & T2. Should you need to lengthen the overall dimension of the plate length to T1, T2 then select a plate extension pack (2 plates per pack & 4no set bolts) will lengthen the plate with a mechanical bolt fixing by 100mm per pack. You can have as many packs as you like!

Step 5 – All windpost require tying into the inner and outer wall with the use of wall ties. We recommend that a wall tie pack is added to your configuration as we supply the stainless steel wall tie, tek-screw/washer and an isolation pad to debond the stainless steel tie from the galvanized stem to prohibit cross contamination of materials.

Wall Ties are installed to suit the brick coursing (usually at 225mm ctrs). Each tie pack consists of 27no ties at 100mm and 13no of your own choice, 40no Isolation Pads, 40no Tek Screws. You can select the Tie B length required using the options online from 75mm to 200mm tie lengths.

Unlike the image below our stems are not pre-slotted for your ties. This gives far more flexibility on site with your brick coursing. The overall sketch below gives a generic example of how a WP2 may be installed within a cavity wall with a base fixing and top cleat fixing to timber (side fix connection). The wall ties through the slots would be to tie in the inner leaf and you can see the wall ties fixed to the angle face to tie in the outer leaf masonry wall.

The length of Tie B should be sufficient to allow an embedment of at least 62.5mm meaning the minimum embedment of 50mm is always achieved after allowing for site tolerances. The tie length will depend on the overall cavity size, and the position of the windpost within the inner wall (and the inner wall thickness). Should you require a tie pack with one side longer than the other as shown below, then you can order a mixed ties pack. You can also buy online additional tie pack and other accessory components.
