For projects with tight timeframes and stringent performance requirements, PMMA/PUMA technology coatings and membranes are appealing due to its ultra-fast cure time, even in extreme weather conditions, and long-term durability.
The use of continuous insulation (ci) for a warm wall design creates an opportunity to leverage newer energy code insulation requirements in a way that also improves the building’s moisture performance.
Thermoplastic roofing membranes, one of the fastest growing forms of low-slope roofing products, come in different material families, including thermoplastic olefin (TPO), polyvinyl chloride (PVC), and PVC alloy. Some attributes shared by TPO and PVC membranes include long-term weathering resistance, cold temperature flexibility, resistance to tear, puncture, and chemicals, and heat-seaming capability.
Introduced in 1986, the negative pressure roof system remains a niche design in the single-ply roofing industry. Also referred to as a ‘wind-vented’ roof, the science behind the system is simple. When an air seal is formed using a newly installed single-ply membrane, a low pressure condition is created on the underside of the roof. Any moisture in the existing wet roof insulation is pulled up through perimeter roof vents.
