INSULKEY® Insulation Retention Pin

Flexible Insulation Retention Clip

INSULKEY® is an innovative insulation retention pin designed specifically for use with the THERMAZEE® cladding support system. Unlike traditional retention methods that require additional fasteners or penetrations through the wall assembly, INSULKEY® slides directly into place, securely holding insulation while helping preserve the integrity of the building envelope. Its versatile design accommodates virtually any combination of THERMAZEE® depth and insulation thickness, including applications where the girt depth exceeds the insulation depth. With no special tools, hardware or complicated installation procedures required, INSULKEY® helps contractors complete insulation installation quickly, efficiently and consistently.

*Spacing of components varies by project based on project specific conditions. Maximum allowable spacing and dead load (weight of cladding) is based on the total load (dead + live) acting on the assembly and connections. Depending on the system, insulation thickness will influence the systems capacities.

Wall anchors must be specified and supplied by KWS for an extended written limited warranty. KWS will specify the exact anchor type, embedment depth and spacing for anchors in project specific engineering packages. ThermaStop thermal isolation washers must be used on all types of wall anchors with the HCI or CI System, regardless of the substrate.
