System accessories

Bauder Thermofol D18 PVC Detailing Membrane.

Guidance for specification option:

  • 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 BauderPVC IE/AE 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.


BauderPVC IE/AE corners.

Guidance for specification option:

  • 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 at an internal corner, and a piece of D18 unreinforced detailing membrane can be used at 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 that 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.
  • Available in all three membrane colours: light grey (RAL 7035), blue grey (RAL 7031), anthracite (RAL 7016).
