Silicone rubber beading attaches to the 19 mm sides of each triangular board. The beading is made of 80 SH silicone rubber and the top of the beading acts as a cover strip on top of triangle boards both outside your Home in a Dome and inside your Home in a Dome.
Silicon rubber is also used between the ground-based struts and the Damp Proof Course membrane (DPC). The rectangular section silicone rubber is 38 mm wide by 20 thick and is cut to length on site. The rectangular silicone is 80 SH (rigid) and is also used around the door frame aperture between the struts and the recycled plastic door frame.
