· The SBS elastomeric mastic provides the membrane with excellent flexibility at low temperatures.
· The non-woven polyester felt (FP) reinforcement on the inside and the polyester felt on the upper surface confer the best mechanical properties to the membrane:
• Maximum puncturing resistance (static and dynamic)
• High tear resistance
· Excellent dimensional stability.
· Application with mechanical fixing offers the following advantages:
· Fast installation.
· Installation is not as affected by the possibility of bad weather.
· Since the membrane is not adhered, it allows for potential movement of the support.
· Finishing membrane in single-layer systems for mechanically fixed deck roofs.
· Non-trafficable roofs without heavy protection: fully adhered single-layer application.
· Technically, the mineral membranes can be substituted by double reinforcement (fibre glass and polyester felt) in fully adhered self-protected single-layer waterproofing systems.
· SUPPORT: The surface must be dry, firm, even, clean and free of loose materials.
· When waterproofing metal roofs, it is recommended that you install the fretwork sheet with the greatest surface area on the upper side, in order to allow installation of the insulation and the membrane.
· The membranes are installed in such a way that no more than three membranes overlap at the same point.
· Overlaps are carried out with flame, with a minimum longitudinal overlap and a minimum transversal overlap of 12 cm, first eliminating the polyester felt from the surface with flame and with the help of a trowel to ensure mastic adherence.
· We recommend using mechanical fixings with washers with a minimum surface area of 1600 mm2, with a maximum diameter of 5 cm for circular fixings and widths no greater than 4 cm for rectangular fixings. Fixings must have a resistance to static extraction equal to or greater than 1250 N. See Annex 2 of the DIT No. 06/0018, where a series of fixings that meets requirements is listed. The site’s wind load, environmental conditions, and local standards must be taken into account with the calculations.
· Installation and measurements will be conducted in accordance with regulations of the UNE 104401 standard.
Roll: 1 m x 8 m
