R-Guard air barrier systems stop air leakage through wall structures, rough openings, sheathing seams, and material transitions making your building air tight. And an air tight building is an energy efficient building. That’s why buildings that meet the world’s toughest energy efficiency requirements use R-Guard. The Bullitt Center, considered the world’s greenest commercial building, selected R-Guard for it’s air and water barrier system.
For energy efficient & waterproof buildings, an air barrier's expansion and contraction capability is key. All the different materials in your RO expand and contract at diferent rates. R-Guard’s STPE products contain 98% solids to expand and contract with all those materials and keep air and water from getting in to your building.
R-Guard’s STPE (Silyl Terminated Polyether) products can be applied to damp substrates and rained on immediately. Not all “polyether” products can do this. It takes rain out of the construction schedule.
