Preparation

Horizontal work

OB25 High Performance Bitumen Primer.

Guidance for specification option:

Solvent based bitumen primer for preparing dry or

slightly damp substrates prior to bonding bituminous membranes and hot melt systems. The solvent blend used ensures the primer is quick drying and ready to apply membranes and hot melt in as little as 30 minutes at 20°C.

Chemical base: Bitumen.
Solids content: 30–40%.
Application temperature: 1–30°C.
Coverage rate per litre: 7–10 m².
Colour: Black.

Insulation

Type

OptiTherm Insulation.

Fixing

OTM-IA Insulation Adhesive.

Waterproof covering

First layer

Type

OTP-T4U 4 kg Torch On Underlay.

Guidance for specification option:

polyester reinforced torch-on underlay, saturated and

coated with high quality SBS (Styrene-Butadiene-Styrene) modified bitumen. The membrane carrier is a tough 160 g/m² polyester reinforcement, giving the material excellent dimensional stability and very high mechanical strength. The membrane is finished on both sides with a thermofusible film for fast and consistent torch-on application.

Roll size: 1 x 8 m.
Weight: 4 kg/m².
Reinforcement type: Polyester, 160 g/m².
Elongation: 50%.
Resistance to tearing (nail): ≥180 N.

Attachment

Torch-on.

Top layer

Type

OTP-AR66 Anti Root Cap Sheet.

Guidance for specification option:

Torch-applied, bituminous membrane which is saturated and coated with high quality SBS (Styrene-Butadiene-Styrene) modified bitumen. It has a 250 g/m² polyester fleece reinforcement and incorporates special additives which provides reliable protection from root growth. The 4 year tests for these additives were passed according to the FLL standards at the Botanic Institute Hamburg. Test certificates are available on request. In addition, OT-Premium AR66 Capsheet has been fully fire tested as part of a designated system in accordance with EN 13501-5 and DD CEN/TS 1187:2012, Broof Test 4.

Roll size: 1.08 x 5 m.
Thickness: 5.2 mm.
Mass per unit area: 6.6 kg/m².
Reinforcement type: Polyester, 250 g/m².
Elongation: 40/ 45%.
Maximum tensile force: 1200/ 1000 N/50 mm.
