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.

Today’s building designers look to continuous insulation (ci) options to deliver a breadth of performance attributes including thermal, moisture, acoustic, and environmental benefits.
