SikaBit ProMelt- Hot Melt Flat Roof System

SikaBit ProMelt is the latest addition to Sika's Roofing portfolio of bituminous, single ply and cold applied liquid membranes. Predominately, this hot applied membrane is used for inverted cold flat roofing areas or podiums, walkways or balconies due to its non-tracking monolithic state.

The hot melt waterproofing system is ideal for New Build construction sites, as the system can be trafficked quickly after installation, and can be easily laid piecemeal around other working trades. The durability and longevity of the system provides the perfect solution for high traffic flat roofing areas.

Hot Melt System Benefits

SikaBit ProMelt System features and benefits

As a system, SikaBit ProMelt is BBA certified for the durability of the design life of the roof, showcasing its outstanding durability. Another benefit to this technology, is that it can be installed all year round, and is backed with the support from Sika's roofing application and technical teams.

A sustainability benefit to this system is that there is less site waste during application, as 15% of the products compound is made using post consumer recycled materials, and the outer thermofusible protective film wrapped around the blocks of hot melt are simply melted with the compound, reducing on site waste.
