4 in x 75 ft RESISTO Waterproofing Joist Guard

Description
Description

Provides waterproof protection for joists that prevents rotting of structural timber under exterior floors, such as patios and balconies. It is a 0.6 mm self-adhesive membrane composed of SBS elastomeric bitumen with a surface made of polyethylene and an underface covered with a silicone release film. Four-inch rolls are ideal for two-inch- wide joists, while nine-inch rolls are used on double joists at the perimeter of the structure and to seal the joint between the wall of the house and the patio.

Features
  • Substantially extends the service life of the patio at low cost
  • Barely visible between the boards
  • Self-sealing membrane around fasteners
  • Pattern-free black membrane, thus unnoticeable through the decking
  • Easy installation at any temperature
  • Compatible with most decking materials, such as treated wood and composite
  • Excellent flexibility
Code: RESJOI4
