Sika-Trocal roofing systems are engineered to eliminate the use of sealant to create a waterproof seal wherever possible, a process that aims to reduce future maintenance requirements as  exposed sealants typically have a service life of 10 years.


Wherever sealants are used in conjunction with Sika-Trocal single ply membranes their compatibility must be checked with the Sika Technical Department to ensure their use will not be detrimental to the performance of the membrane. This is particularly relevant when other products such as patent glazing or rain screen systems are interfacing with the membrane.


AT Universal and AT Metal are structural adhesives used to supplement the fixing of Sika-Trocal Metal flashing details by bonding them to a suitable substrate, they are not used as an external sealant.
