TIMBER ROOF TRUSSES
One aspect of the building industry that has undergone something of a quiet revolution in recent years is timber roof trusses. Ecostrut (Pty ) Ltd is a Mitek Licenced company that manufactures and installs timber roof trusses for a wide variety of customers ranging from domestic to commercial. Our timber trusses are manufactured through the use of state-of-the-art Mitek 20/20 software provided by Mitek Industries who have been our partners since inception. We manufacture nail-plated trusses as well as bolted feature trusses. Our plated trusses make use of galvanized connector plates and South African Pine graded timber according to SABS DESIGN CODES and NATIONAL HOME BUILDERS REGULATIONS. Our mission is to provide customers with fine-quality timber roof trusses and you can always expect well-detailed workmanship from our highly skilled professionals. We manufacture timber roof trusses of any shape and complexity and generate custom designs based on your building plans. We will give you peace of mind that our timber roof trusses will keep you safe and sound for many years to come.
HYBRID ROOFS
For a conventional warm or inverted flat roof, the presence of a suspended ceiling internally makes little difference to the overall thermal performance of the roof.
The ceiling system contributes no thermal resistance of its own (unless it is well-sealed). In addition, fixing the ceiling system to the underside of the roof deck does not impact the main components of the roof system. The AVCL, insulation, and waterproofing layers are all above the structural roof deck, and so don’t interact with the ceiling system at all.
When specifiers and installers opt for a hybrid roof arrangement, however, then questions must be asked as to whether the U-value calculated in theory will match the performance of the roof in reality.
A hybrid flat roof features thermal insulation above the roof deck (as in a conventional or inverted warm roof), and an additional insulation layer fixed below the roof deck. It, therefore, has characteristics of both warm and cold roof construction, hence being described as a hybrid.
The insulation below the roof deck is typically on the inside of the air and vapor control layer (AVCL), whereas general construction practice is for AVCLs to be on the warm side of the majority, if not all, insulation. Because they sit in this grey area, hybrid roofs are not formally recognized by standards that deal with best practices in roof construction.
