SikaShield® VB P42 S 3 mm is a modified, bituminous, torch-applied, waterproofing membrane. It is reinforced with a dimensionally stable non-woven polyester inlay. It can be applied to various deck types and surface combinations.
These vapour barriers offer increased high-performance that enhances watertightness. The engineering of the membranes gives improved elongation and cold flexibility, which also contributes to increased mechanical properties such as tensile, tear, and shear. The membranes have good resistance to impact and are easy to install by torching method. There is a choice of primers to suit substrate and weather conditions.

SikaShield® VB E71 PE SA 3 kg/m² is an SBS modified bituminous, self-adhesive vapour control layer. It is reinforced with aluminium foil and a dimensionally stable non-woven polyester inlay.
This membrane is a heat transfer, self-adhesive application, for use with Safe2Torch and combustible materials, where torch application is not advisable. The membrane offers high resistance to vapour movement and enhanced watertightness. It also features high elongation and high mechanical properties, which make it an excellent membrane for specification. The membrane also accommodates a wide range of roof systems, deck types and substrate combinations, which gives the option to tailor the specifics of a project.
Air and Vapour Control Layer for SikaShield® Bituminous Membranes
FAQ
A bitumen vapour control layer is a bitumen-based membrane installed within a roofing buildup to prevent warm, moist air from inside a building from reaching colder layers, where it could condense and cause damage.
Bitumen vapour control layers are used in flat roof constructions beneath insulation and waterproofing membranes.
Bitumen vapour control layers play a critical role in flat roof construction by preventing warm, moist air from inside the building from reaching colder parts of the roof buildup. Without a vapour control layer, this moisture can condense within the insulation or structure, leading to reduced thermal performance, mould growth and long-term damage.
Sika offers torch-applied and self-adhesive bitumen vapour control membranes. Some membranes feature aluminium reinforcement for enhanced water vapour resistance.
Sika bitumen vapour control layers can be applied using torch-applied or self-adhesive methods.
Consider factors such as internal humidity, insulation type and roof buildup. Contact a member of our team for technical support to ensure the correct specification for your project.
Sika bitumen vapour control membranes are fully compatible with the SikaShield® bituminous membranes systems.
