ATAS International Inc. has rebranded its ATAS ASV (above sheathing ventilation) shim to the ASV/TB shim. TB is for thermal break, which the product achieves, along with providing ventilation above the sheathing.
By incorporating ASV/TB into a roof design, it ventilates the air space between the roof cladding material and the subassembly and roof deck. This allows for the temperature of the roof cladding to be closer to the outdoor ambient temperature and reduces heat gain passing through the roof assembly in the summertime, as proven by studies and testing performance sponsored by the Metal Construction Association at Oakridge National Lab. ASV/TB also adds insulation value during the winter and minimizes the effect on condensation between the roof layers and wall assembles.
A thermal break is an insulating material that is strategically placed between highly conductive structural components within the building envelope, acting as a thermal barrier to interrupt the flow of thermal energy. ATAS’ ASV/TB reduces the transfer of heat from one side of the structural component to the other, acting as a thermal barrier, and significantly enhances the energy efficiency of a roof or wall assembly.
Incorporating ASV/TB into a roofing or wall cladding system is one of several components that can contribute to a better performing roof or wall and a more energy-efficient building, resulting in energy cost savings and a means to reduce carbon impact on the environment.
ATAS has also added a fourth underlayment to its product offerings: PanelShield™ SA by VaproShield. This wall panel underlayment offers many positive attributes: It creates a water-resistive air barrier when applied outside the wall sheathing, does not require primer, is cost-effective and offers 12 months of ultraviolet and weather exposure, which is ideal for long-term projects.
