One of the greatest challenges in working with concrete roof decks is mechanically attaching the insulation and membrane. Fasteners frequently fail to penetrate fully, or the process causes damage from cracking or excessive pressure – either below or on the top surface of the roof deck. Likewise, the labor and material needed to install fasteners in solid decks can be extremely expensive. In addition, concrete roof decks can hold residual moisture as a result of past leaks, which can have a negative effect on many types of membranes. The Fulton Science Academy was facing all these issues when choosing a roof for their private-school location in Alpharetta, GA.
Fortunately, the V2T roof system is uniquely well suited to resolve all of the common problems associated with concrete roof decks. The vacuum-sealed nature of the system eliminates the need for fasteners – instead using the power of the wind to lock roof membranes and vents in place. At the same time, the vacuum created by the patented V2T vent design has a “drying effect” that removes air as well as moisture from beneath membrane surfaces. The result is a stronger, well-sealed roof that installs faster and with fewer chances for problems on the concrete decking surface.
In total, the Fulton Science Academy roof installation included 19,021 square feet of ½-inch DensDeck with new Carlisle 060-mil Carlisle TPO membrane and V2T Vents. The owner’s requirements were met with a comprehensive manufacturer’s warranty from Carlisle that covers all components of the roofing system, including the revolutionary V2T vents. The man power saved by eliminating the time-consuming process of fastening into concrete reduced the overall project cost by close to 30%.
