Knight Wall Systems today announced the company has introduced a
new horizontal-girt rain screen attachment system – called HCI-System – that enables
ASHRAE 90.1-compliant continuous insulation with vertical cladding, according to
company president Doug Knight.
“We’ve had tremendous success commercializing our rain screen CI-System,” Knight
said, “which is a vertical girt attachment system, great for horizontal cladding. The new
HCI-System allows vertical cladding to be installed directly on top of the HCI girt
without the need for a second rail.”
The HCI-System is a stiffened, ventilated horizontal rail (girt) that can span up to 32
inches on center. Roll-formed in-house at Knight’s Eastern Washington fabrication plant, the ¾” thick attachment system is available in 16- or 18-gauge Galvalume (standard or black Fluropon finish) or stainless steel. As with the original CI-System rain screen, should a secondary rail be needed, Knight produces additional standard or custom HCISystem rails for a variety of cladding types.
Designed for rain screens with fiber cement, metal-panel and aluminum composite
material (ACM) cladding, among others, the HCI-System can be used both stand-alone
and in conjunction with Knight’s CI-System, affording any building envelope project a
great deal of flexibility.
