A mechanically fastened roof is generally quick and economical to install and because of its lightness in weight, will often enable savings to be made on the supporting structure. Additionally, as the membrane is exposed, any alterations are easily executed, as access is easy. The wide range of fasteners now available means that it is possible to mechanically fix an exposed Sika-Trocal membrane to virtually any type of deck.
The exposed, mechanically fastened membrane roof is the most widely specified option.
Sika-Trocal Type S membrane is suitable for mechanically fastened roofs in both new build and refurbishment applications, and generally provide the most rapid and economic system to install, utilising a Sika-Trocal Laminated Metal Disc and thermally broken fastener to secure both the membrane and the insulation rather than the separate fastening system used by many other single ply systems.
The Sika-Trocal Disc systems is generally accepted as the quickest, enable savings in time and cost. Furthermore there are no penetrations through the actual waterproofing.
