The Type HS System is designed for vegetative roofs with multiple pitches ranging from 15 to 45 degrees. The Type HS System consists of:
• HG 3623 - 2.3” Sloped DR Board • HG 3441 - Type HS: Shear Grid
Specific to this product, it:
runs perpendicular to the roof slope over the 2.3” Sloped DR Board from the eave to the roof peak
features a rhomboidal indentation texture (1.5 +/- 0.1mm) that creates friction and helps to keep fill in place
has a perforation pattern that allows water to move freely through the product without washing out the material
provides a simple method to secure sedum blankets with cable tie lockdowns through perforations
is easily cut with industrial shears
