Description

Single ply Thermofol polyvinyl chloride (PVC) cold roof system incorporating Thermofol single ply membrane for mechanical fixing.

Bauder Single Ply Thermofol PVC Roof system 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. Can also be used for extensive green roof situations.

See BBA certification 06/4354. Thermofol can meet current UK Building Regulations Part B for external fire protection.

Key features:

  • Membrane is lightweight with high tensile strength of 1000 N/50 mm.
  • High quality polymers ensure membrane stays flexible at -30°C.
  • Formulation resistant to micro-organism attack.
  • Installation using hot air welding for strong joints.
  • High performance halogen-free fire retardant.

Benefits:

  • Membrane is resistant to tears.
  • Resistant to European climatic conditions.
  • Approved for green roof landscaping by FLL.
  • Flame-free installation.

Please note that profile metal decks will require a plywood/ Oriented strand board (OSB) overlay for cold roofs.

Product Options

Detailing:

The waterproofing should be turned up by at least 150 mm around features such as rooflights, parapets and service pipes passing through the roof. Detail work to upstands, edge details, flashings, etc. should be carried out using either Thermofol D membrane adhered directly to the substrate using Bauder Thermofol Contact Adhesive or mechanically fastened using Thermofol U membrane. Detailing should be carried out with a separate flashing. Consult Bauder for further information on detailing.

Accessories:

- Bauder Thermofol D18 PVC Detailing Membrane:

  • This unreinforced detailing membrane is manufactured from Polyvinyl Chloride membrane (PVC). The product is highly flexible due to the incorporation of internal plasticizers during the manufacturing process. This combination of materials provides high elongation, good thermal stability and flexibility. Complex three-dimensional detailing to curves, pipes or awkward shapes can be formed using Thermofol un-reinforced D18 membrane. Otherwise Thermofol pre-formed corners must be used at intersections and returns.
  • Available in all three membrane colours: Light Grey (RAL 7035), Blue Grey (RAL 7031), Anthracite (RAL 7016).
  • Membrane to be either fully bonded using Bauder Thermofol Contact Adhesive - Drum or mechanically fixed according to the construction - refer to the Bauder Single Ply Installation Manual for further guidance.

- Bauder Thermofol Pre-formed Corners:

  • Pre-formed PVC internal and external corners for use with Thermofol membrane.
  • These products are designed to dress into 90° corners, they can be warmed and manipulated to fit corners over and under 90°. If this is not possible a gusset must be dressed to an internal corner and a piece of D18 unreinforced detailing membrane can be used to an external corner with a ‘thumb print’.
  • Internal (90 x 90 mm) and External (150 x 170 mm) pre-formed corners can be reversed to allow them to be used at other junction points to ensure a watertight seal is easy to achieve.
  • Pre-formed corners must be fully heat welded from the centre outwards working around each side until the entire patch is welded.
