Description

Total bitumen green inverted roof system, incorporating torch-on bitumen root resistant capping sheet with self-adhered bitumen underlayer, insulation and self-adhered bitumen vapour barrier.

Bauder Total Green Roof System (BTGRS) is suitable for a variety of applications on both new build and refurbishment projects and can be used in warm, cold and inverted roof scenarios.

Bauder Inverted Roof systems should be ballasted/ landscaped to prevent wind uplift and/ or floatation. Type, thickness, weight of landscaping should be agreed with Bauder per bespoke project basis.

See BBA certification 10/4744. BTGRS can meet current UK Building Regulations Part B for external fire protection.

  • Application temperature: +5 to +30°C.
  • Drying time (at 10°C): 5–10 minutes.
  • Colour: Black.
  • Recoat time if left exposed: Four hours.
  • Suitable substrates: Oriented strand board (OSB); plywood; timber; concrete; lightweight concrete or cementitious materials; metal; Bauder self-adhesive underlayers; existing asphalt and bitumen membranes; polyisocyanurate (PIR) insulation.
  • Non-suitable substrates: Mica finished surfaces (e.g. KSD FBS); Laminated paper-foil faced insulation; expanded polystyrene (EPS) or extruded polystyrene (XPS) insulations; BauderROCK or mineral wool insulation; BauderGLAS or cellular glass insulation; copper; thermoplastic waterproofing membranes.

Attachment

Loose laid (and suitably ballasted).

Guidance for specification option:

  • Setting out: Loose lay insulation directly over the capping sheet to brick pattern with staggered joints. Minimize cutting and avoid small pieces at perimeters and penetrations. Dependent upon the total thickness required, it may be necessary to construct the insulation using two layers of board. The manufacturer/supplier can advise on the available combination options.
  • Joints: Butt together.
  • Loading over inverted insulation (minimum): Ballast (landscaping) should be installed onto the Bauder WFRL Membrane (Water Flow Reducing Layer) to a minimum depth required to achieve a permanent minimum 80 kg/m² and load which prevents wind uplift and flotation of the insulation in high winds and/or heavy rainfall.
  • Additional loading at perimeters: On high buildings in more exposed areas, wind uplift may be a problem and in these instances paving slab ballast must be considered. Paving slabs should be a minimum of 50 mm thick. The slabs should be laid on paving slab supports of minimum 175 mm diameter (or equivalent base area).
  • All final details must to be confirmed with Bauder before proceeding.
