Sika provides a full range of single-ply and built-up flat roofing systems incorporating both flexible sheet and liquid applied membranes.

Demand in this segment is driven by the need for eco-friendly, energy-saving solutions such as green roof systems, cool roofs and solar roofs, which simultaneously help to reduce CO2 emissions.

While refurbishment projects continue to gain significance in the mature markets, the emerging markets are moving towards higher quality roof solutions.


Two new liquid applied membrane systems have been launched onto the market. Sikalastic® 641 is a low-odor product with significantly reduced solvent and VOC content. It is based on the patented i-Cure® hardener technology and has been developed specifically for use in highly sensitive areas, such as hospitals, food manufacturing plants and schools. Sikalastic® Evercoat Zero-1 is a one-component polyurethane system which has successfully been introduced to the Asian market.

Since no mixing is required, the application, and consequently construction time, is shortened. Sika has also developed an online specification tool which helps customers choose the right products for their projects. Not only does the tool help to identify the most appropriate system, it will also conduct a life-cycle cost analysis which can be used to compare against other products.
