EXi 2.5 Interior Surfaces Applications

The EXi 2.5 is our most vesitale interior/exterior grade panel it is optimized for masonry or framed construction it combines all the best features of continuous insulation that is ready for finishing. The EXi is the same dimension as 2x3 dimensional lumber, so standard electrical and framing can be utilized. The panel combines insulation, attachment strips or furring, with self-flashing panels. Thus eliminating parts, pieces and guess work with the in the field conditions. The biggest benefit is that there are no special tools or training required to install these intuitive panels successfully.

Engineered Features

R-10 Continuous Insulation

At 2½-in thickness, the EX 2.5’s closed-cell, injection-molded EPS foam body achieves R-10 insulation.

EPS is a non-toxic, inert insulation that maintains its R-value throughout the life of your building. Because it does not absorb moisture like open-cell types of bead board, it is rated highly for below-grade applications like basements. The EPS body has a fire-retardant material and serves as a Class III vapor barrier.

Mold-Resistant Studs

Each panel is co-molded with three high-strength polypropylene studs that align every 16-in O.C. The anterior surfaces are fully embedded by a ½-in of insulation while the posterior surfaces feature ribbed dovetails for adhesive applications against interior concrete, stone, metal or brick walls.

They provide a straight surface that can support drywall attachment and exterior finishes as well as adornments like cabinets and TVs. They are not prone to moisture damage, and do not conduct heat along a wall system.

Self-Leveling Tongue-and-Groove Interlocks

Four tightly interlocking edges along each panel form a continuous, self-flashing seal. Unlike traditional flashing tapes, the interlock create a resilient seal that will not change shape, dry or crack over time. They eliminate the potential for mistaken thermal leaks and prevent water from reaching the face.

A notched alignment system ensures the panels and studs stay aligned during installation even when cut. Inset lines demarcate the location of wiring chases.

Moisture Control

Built into the front and back of the EX panel is a network of shingle-style capillary channels. They comply with Oregon Residential Speciality Code section R701.1 allowing the panel to serve as a certified rainscreen for exterior applications.

The channels are specifically-sized cavities that moderate wall pressure so that both interior and exterior wall assemblies can drain and be allowed to remain dry.

Electrical Raceways

Electrical raceways run vertically at 16 inches on center and horizontally at 24 inches on center.

This grid provides easy access to pull wiring to any location. Located at code-approved depth, the chases also provide the necessary separation from the drywall face to protect the wiring.
