SikaShield® E65 MG FR 4 mm

SikaShield® E65 MG FR 4 mm

160 mils SBS bituminous cap sheet, torch-applied

SikaShield® E65 MG FR 4 mm a 160 mils thick SBS-modified bituminous membrane. It is reinforced with a non-woven polyester fabric dimensionally stabilized with fiberglass and is flexible at -4 °F (-20 °C). The top surface is coated with mineral granules, which allows the permanent exposure to UV radiation. The underside of the product has a burn-off film for easy torch application.

  • Can be installed by torch, mop, cold adhesion or mechanical fixation
  • High impact resistance
  • Highly flexible in cold temperatures
  • Fully bonded
  • Very good mechanical properties (tensile, tear, shear)
  • Tiles can be placed directly onto the membrane
  • Can be painted/coated immediately after applicatiom

Application steps

SUBSTRATE QUALITY

  • The supporting structure must be of sufficient structural strength to support all new and existing layers of the system build-up.
  • If used as a roof system, the complete system must be designed to withstand and be secured against wind uplift loadings.
  • The substrate surface must be uniform, firm, smooth and free of any sharp protrusion or burrs, clean, dry, free of grease, laitance, oil, dust and loosely adhering particles.

APPLICATION

To avoid coinciding joints, lay the membranes parallel to one another, align it properly, ensure the specified overlaps are followed, and then re-roll it before application.

                     

MEMBRANE OVERLAPS

         

  • Overlap the membranes by a minimum of 4" (100 mm) on the sides and 6" (150 mm) on each end. 
  • At the end overlap, cut off a corner measuring 4" (100 mm) per side at an angle of 45°.
  • End laps must be staggered 18'' (46 cm) apart.
  • Offset cap sheet side and end laps so they are positioned at least 12'' (28 cm) away from any base ply laps.
  • A mininum 20 lb (9 kg) roller must be used on all side and end laps, following immediately behind the heat welding. Apply uniform pressure across the lap area while the bituminous compound is warm to ensure a positive bond.
  • A continuous bead of asphalt approximately 1/4 inch wide should be visible at all laps after application.
  • The edge of the seam must be left untooled (not buttered).

 

IMPORTANT: DO NOT STACK LAPS!

      

    

TORCHING

 

  1. Heat the substrate and the backing film on the underside of the membrane with a gas burner.
  2. When the backing film starts to melt, the membrane is ready to stick.
  3. Roll the heated membrane forward and press it firmly against the substrate to bond it.
  4. Make sure a bead of melted bitumen is visible along the full length of the overlap sides and ends when laying.
 

                          

Suitable substrates for torching:

 

  • Concrete
  • Gypsum coverboard
  • Perlite screed
  • Bituminous membranes with a smooth surface
  • Coatings (check the compatibility)
  • Brick masonry
  • Cementitious screeds            

 

DETAILING

        

Use a sharp knife to cut in all details such as internal and external corners, upstands, vent pipes, drains, support metalwork etc.

   

Refer to the relevant method statement for further information on detailing.
