Mapei Spider P SA | Prefabricated Self Adhesive Bitumen Membrane

PREFABRICATED SELF ADHESIVE BITUMEN MEMBRANE PRODUCED USING ADESO TECHNOLOGY (NO FLAME. NO TORCH. NO FIRE RISK.)

Description

SPIDER P SA is a top-quality prefabricated SELF-ADHESIVE bitumen membrane produced using ADESO technology, the innovative ELASTOMERIC-PLASTOMERIC (Plastomer-Polymer Bitumen) compound laminating system developed by Polyglass SpA. In the ADESO membranes, the exclusive SEALLap polyurethane self-adhesive system further improves the bond along the side laps of overlapping membranes as they are applied. In the mineral versions, the ADESO membranes feature the FASTLap system, the head selvedge free from slate chippings, which allows a faster and easier application and a better sealing of the overlaps. SPIDER P SA is a membrane produced to the standards set by NAT technology, the production system for the control of polymer matrix ageing in bitumen membranes. SPIDER P SA has a polyester non-woven carrier, stabilized with glass strands parallel to the machine direction. The carrier gives good puncture resistance, dimensional stability, and tensile strength in all directions.

Uses

Immediate waterproofing of the construction.

• SPIDER P SA can be applied as part of a MULTI-PLY ROOF, in EXPOSED waterproofing systems, as a BASE LAYER or CAP SHEET, and in BALLASTED waterproofing systems, as a BASE LAYER

• SPIDER P SA can be used as BASE LAYER on insulating panels that are not heat resistant so that torch-on waterproofing bitumen membranes can be applied on top as a SINGLE-PLY solution

• SPIDER P SA is suitable for application on FOUNDATION walls to deal with RISING DAMP or percolating water, as part of a SINGLE or MULTI-PLY system, or as an under-floor MOISTURE BARRIER

• SPIDER P SA can be applied as UNDERLAY FOR DISCONTINOUS ROOFING

• SPIDER P SA is a VAPOUR DIFFUSION CONTROL LAYER designed for use under insulating material to ensure it has a long service life. The right VAPOUR DIFFUSION CONTROL LAYER for the job must be determined based on the existing roof build-up, checking for condensation formation (with the aid of a Glaser diagram)

• Under no circumstances should roofing tiles be applied directly on top of the bitumen membranes by mortar, adhesives or expanding foam; in fact these would not permit a secure fixing system, as well as the necessary ventilated space under the roofing tiles

Characteristics & Advantages

FASTLap®: Patented productive process for granulated sheets with granule-free sides and ends for easy overlapping

Benefits:

• No need for heating and scraping granules at ends

• Shorter installation time

• Reduced material and labour costs

• Faster, quicker, cleaner and easier roll lapping

• Stronger, more reliable seams

• Aesthetically attractive finish

• Fewer call-backs and repairs
  
   

SEALLap®: Unique factory-applied adhesive treatment at membrane overlaps for enhanced sealability

Benefits:

• Instant adhesion between adjacent membranes, even when the temperature is particularly low

• No need for adhesives or mastic tapes

• Reduces the application time

• Reduces the application costs

• Ensures a quick, clean and easy adhesion of the sheets

• Remarkable binding capacity of the overlaps
