ArchiGreen

ArchiGreen^®'s PS-B paving spacers are made of recycled polystyrene and are black in colour. PS-B 3 has a leg thickness of 3 mm and PS-B 5 has a leg thickness of 5 mm delivering accurate 3 mm and 5 mm joints respectively on green roof terraces where slabs must be loose laid for proper drainage.

As per image at the weakened junction two narrow cuttings are incised into both sides of one of the spacer legs at the joining point with the rest of the spacer. This weakened leg at the weakened junction is known as the break-off leg that can be easily snapped off as indicated in the next image.

The PS-B 3 paving spacer is used to demonstrate the formation of a T-shaped spacer and the reuse of the snapped off legs to form a new cross-shaped paving spacer.

ArchiGreen^®'s PS-T paving spacers are made of recycled polystrene and are transparent. Just as their PS-B counterparts, PS-T spacers are also available in 3 and 5 mm leg thickness. Their use are strongly advised on green roof terraces where slabs must be loose laid for proper drainage.
