Other

Laying recommendations:

• the use of sheets with a maximum length of 5 m is recommended
• prevent direct contact of the metal with the torch flame in order to avoid damages to the sheet or detachments
• weld the sheets by mainly heating the underlying membrane
• it is preferable to use membranes reinforced with glass sheet or composite polyester as a first seal layer
• avoid site handling on the product, especially after torching
• it is good rule to wear suitable wide sole and heelless footwear so as not to damage the metal sheet
• use mechanical anchoring every 20 cm for slopes over 20%
• any application of MEGAVER CU on thermal insulation must be agreed in advance with the BITUVER Technical Service
