Walls – “Snap” to Install

With our tongue-and-groove design, PermaTherm’s z-lock panel joint delivers seamless walls and a tight thermal fit. Its ingenious and simple design provides continuous insulation throughout the panel system. It reduces thermal bridging (heat loss) which often isn’t possible with more complex installation designs. PermaTherm panels easily attach and secure to the superstructure within the building and may enhance the building’s overall strength and rigidity.
