The future of high-performance building envelope.

ThermalTight™ solves the problem of installing multiple control layers on exterior walls by combining Neopor® GPS rigid insulation with high-performance WRB into a single panel that controls water, air, and thermal—all while allowing vapor to escape so the building can dry. It simplifies good building science.

One panel = One trip around the building

ThermalTight™ combines two essential building envelope materials into one, easy-to-install panel: Neopor® GPS semi-vapor permeable rigid insulation by BASF, and a high-performance WRB laminated to the exterior of the panel, that acts as both a water and air barrier.

Highest long-term R-value on the market

ThermalTight™ is made of Neopor® GPS, giving it an lifetime R-value of 4.7 per inch. That’s the highest R-Value on the market. It is also unique in its class—increasing in R-value as air temperatures drop.

Sustainable and energy efficient

ThermalTight™ is made of insulation that is GREENGUARD Gold Certification and has been referenced by both The Collaborative for High Performance Schools (CHPS) and the Leadership in Energy and Environmental Design (LEED®) Building Rating System.

What They’re Saying

“We liked the fact that the entire house was wrapped in the ThermalTight blanket, rather than foam sandwiched between OSB like other products.”

—Ray & Kim, Homeowners, Tupelo, MS

“ThermalTight is the perfect continuous insulation solution. We love this product’s ease of use and performance it adds to our buildings.”

—Garrett Hogan, Principal, OnPoint Development

The ThermalTight™ System

The ThermalTight™ System makes it easier to build better, with a wall system that solves the challenge of building airtight, watertight, continuously insulated to limit thermal bridging, and designed to stay dry, all while ensuring a simple, labor-saving installation process.

Backed by a 15 year warranty, the components include ThermalTight™, ThermalBuck™, and BRINC Fluid FS, a dual-purpose flashing and sealant.

Features & Benefits

ThermalTight™: How it works

ThermalTight™ combines two essential elements—rigid insulation and weather barrier—into a single, integrated panel.

The self-gasketing, vapor-permeable WRB features an innovative patented flap system used to seal the panels together, creating a superior water & air barrier. The Neopor® semi-permeable GPS insulation delivers the highest true R-value performance over time (R 4.7 per inch), and contains no blowing agents—making it one of the greenest rigid insulation materials.

Water – Air – Vapor + Thermal

Building Science experts have proven that there need to be four control layers in every wall: Water, Air, Vapor, and Thermal.

Effective wall systems rely on good design, craftsmanship, AND simplified installation techniques to achieve their desired performance. If it’s too complicated to execute, it isn’t going to work. Each ThermalTight™ panel has the four essential control layers in one building material, making it easier to achieve performance goals.
