MINIMIZING THERMAL BRIDGING IN BUILDING APPLICATIONS

How SNS Thermal Break Technology works

Sealed “N” Safe (SNS) has engineered a specialized Thermal Spacer block that creates a definitive thermal break. By placing the SNS Thermal Spacer block continuously on every purlin and/or girt, it isolates the outer shell from the inner frames thus creating a Thermal Break Technology which increases insulation performance by 30% to 50% and doubles the efficiency of most screw-down applications. With a typical ROI of just 18 to 26 months, it is one of the most cost-effective ways to optimize a building’s thermal envelope.


Energy Efficient Systems by SNS

SNS manufactures an energy-efficient system that is both cost-effective and easy to implement. The SNS systems are specifically engineered to meet or exceed US Energy Codes (ASHRAE & IECC) by utilizing the SNS Thermal Spacer Block.


The Science of Continuous Insulation

The SNS system minimizes thermal bridging—the primary cause of energy loss in metal buildings. By combining the SNS Thermal Block with typical Metal Building Insulation (MBI), we create an R-6.5 Continuous Insulation (CI) System for the complete envelope of the metal building.  This achieves a continuous thermal break, boosting insulation performance by 30% to 110%, based upon whether it’s a Standing Seam or Screw-down application.

ASHRAE defines Continuous Insulation as: “A Continuous Insulation System must comprise of insulation that is uncompressed, and continuous across all structural members without thermal bridging other than fasteners and service openings.”
