Exterior insulation is required by code – and it’s good building science, because it prevents “thermal bridging”, or energy escaping though the studs. But it’s yet another layer builders have to deal with on the building envelope. What if it wasn’t?
Insulation + WRB in one panel. Introducing ThermalTight
ThermalTight combines two essential building envelope materials into one, easy-to-install panel: Neopor GPS rigid insulation by BASF, and a self-gasketing WRB laminated to the exterior of the panel. The WRB features an innovative patent-pending flap system used to seal the panels together, creating an excellent water & air barrier. Better yet, it’s vapor permeable – which means the walls can dry out.
Powered by Neopor
ThermalTight is built on Neopor graphite polystyrene rigid insulation by BASF. Neopor maintains the highest long-term R value on the market by using graphite to reflect heat energy, instead of blowing agents that can escape over time. One of the “greenest” rigid insulation materials, it’s versatile (ideal for walls and roofs, above and below grade) and works beautifully in any climate.
Unlike most insulation materials that lose their R value over time, Neopor POWERS UP when the temperatures drop, increasing from an R 5 (per nominal inch)* at 75° F, up to an R 5.4 at 25°F. No other insulation material provides as much performance and value as Neopor.

With the WRB on the outside, installation is easier
Both control layers go up at one time, saving time and labor on the job site. By adhering the WRB to the outside of the rigid foam (rather than up against the sheathing) it can do a better job of managing bulk water. It’s also easier to find and fix any air or water leaks found during blower door testing, and easily repair them. The WRB on ThermalTight features a patent-pending flap system with double sided taping underneath the flaps, to eliminate the “reverse shingle” common with panel systems that require taping on top of seams. Preventing moisture damage is essential – and building with ThermalTight makes difference.
Forget walls that “breathe”. They need to dry out
Buildings need to dry. But they also need to be airtight. And the tighter we build, the more important it is to ensure that the wall assembly is designed to dry. That’s where vapor permeability comes in. To properly manage moisture, a wall assembly needs to allow vapor to pass through it both ways. Vapor permeable materials on the building envelope and the entire wall assembly AND the climate are both important considerations when choosing building materials.
One each ThermalTight panel, the Neopor and the WRB have different levels of vapor permeability. This helps manage moisture flow, allowing the wall to dry at a controlled rate.
ThermalTight makes it possible to manage Water – Air – Vapor + Thermal all in one panel, with one less trip around the building envelope.
- Air Barrier
- Vapor Permeable
- All in One panel
It’s good building science.

What about the windows? ThermalBuck
Installing windows on a building with exterior insulation isn’t easy. Traditionally a wood buck is built – but wood bucks are time consuming to install, difficult to flash, and can warp and shrink over time. A wood buck also creates a new thermal bridge – which makes no sense in a wall you’ve just completely insulated to avoid them. Wood is also a condensation point for moisture – and a potential liability.
ThermalBuck, the high-performance window buck, is the ideal solution. Each buck comes in 8′ lengths and 7 different sizes to match the thickness of the exterior insulation. Cut to fit on site, ThermalBuck insulates the RO with an R value of 4.4 per inch. Coated in a waterproof resin and installed with high-quality sealant, ThermalBuck creates a brand new watertight, airtight, insulated rough opening for the windows and doors, solving one of the biggest hurdles builders have with meeting codes for continuous insulation.
One system, one warranty, one manufacturer
The complete ThermalTight System allows builders to choose one high-performing system to meet multiple building codes, while ensuring a simple, labor-saving installation process.
Backed by a 15 year warranty, the components include: ThermalTight, ThermalBuck, BRINC Flashing Tape, BRINC Flexible Flashing Tape, BRINC Double Sided Tape, DAP DYNAFLEX 800 sealant and DAP DRAFTSTOP 812 spray foam.
