Sika-Trocal

Since their introduction in the 1970's single ply membranes have changed the perception of flat roofing, affording a freedom of design that has made them the first choice for many specifiers. The key to this change is the combination of carefully formulated quality roofing membranes installed by manufacturer trained specialist contractors, central components of the Sika-Trocal concept since 1972. This site contains all the required information on Sika-Trocal including the unique Sika-Trocal disc fastening system, multi-vault rooflights, and SikaSpec, Sika's comprehensive online specification tool for architects and specialist contractors.
