Liquid-applied waterproofing	-
Type	OB-HM OptiBond Hot Melt Blocks. Guidance for specification option: Approximate coverage (two layers at 3 mm per application): 6 kg/m². Normal laid thickness: 6 mm. Softening point: 55–85'C. Penetration: 45–75 mm. Low temperature flexibility: ≤-15' CBS EN ISO 1109:2000 - Pass. Flow resistance: <3 mm.
Reinforcement	OB-RF OptiBond Reinforcement Fleece. Guidance for specification option: A spunbond polyester reinforcement layer, installed between the two applications of OptiBond-HM. Roll size: 1 x 200 m. Weight: 52 g/m². THickness: 0.46 mm. Air Permeability: 5500 1 m².s (at 200 Pa). Tensile strength: 40 N/5 cm.
Insulation	-
Type	OptiTherm Insulation EPS/ XPS.

Water control layer	WFRL Water Flow Reducing Layer.

Protection layer	OB-OptiBond Anti Root Protection Layer. Guidance for specification option: A root resistant protection sheet/ capsheet. It is an SBS modified bitumen membrane containing a chemical root retardant with a polyester reinforcement carrier. The membrane is produced with a charcoal slate mineral finish that acts as an additional mechanical barrier to help prevent root ingress. The chemical additive is specifically designed to be used in waterproofing products making OB40-AR Protection ideal for use on flat roofing systems under living roofs and podium gardens. OB40-AR Protection is designed to be used in conjunction with the OptiTorch Premium Layered Roof Waterproofing Systems or with OptiBond-HM Hot Melt Waterproofing Systems as a replacement for OB36-SD Protection. Roll size: 1 x 8 m. Mass per unit area: 5/m kg. Straightness: ≤1 mm/m. Flexibility at low temperatures: ≤-9°C. OB-SD36 OptiBond Sanded Protection Layer. Guidance for specification option: A high performance access layer composed of a reinforced polyester core, coated with a specially formulated quick melt SBS modified bitumen. Both upper and lower surfaces are coated in a fine sand finish, which prevents the roll from sticking together in storage and installation. OB36-SD Protection is designed to be used in conjunction with the OptiTorch-Premium Layered Roof Waterproofing Systems or with OptiBond-HM Hot Melt Waterproofing Systems. Roll size: 1 x 20 m. Mass per unit area: 1.8/m² kg. Straightness: ≤1 mm/m. Flexibility at low temperatures: ≤-9°C.
