Johns Manville introduces black PSK duct wrap
Engineering360 News Desk | June 07, 2019Building products manufacturer Johns Manville (JM) has introduced a black-coated polypropylene-scrim-kraft Source: Johns Manville(PSK) duct wrap insulation, Microlite Black PSK duct wrap.
Like JM’s other Microlite duct wrap insulations, this new insulation is formaldehyde-free and has a facing with a perm rating of 0.02. The new duct wrap is designed for aesthetic applications that need a high-quality insulation.
This material allows installers to meet aesthetic design requirements calling for black insulation without resorting to painting the insulation facing, a method that can void the UL fire rating required by the 2015 International Mechanical Code (IMC). The new black-coated PSK facing on Microlite Black PSK meets the 25/50 flame spread/smoke rating required by the 2015 IMC.
Microlite Black PSK rounds out the JM formaldehyde-free duct wrap portfolio. Customers now have the choice of three different insulation facing colors: Black PSK, White PSK or Silver FSK (foil-scrim-kraft). The Black and White PSK were designed for aesthetically targeted applications, while the Silver FSK is intended for more traditional applications, like those behind closed walls or ceilings.
Given that the Black and White PSK insulation will be used largely for aesthetic purposes, JM also released matching PSK seaming tape for both the Black PSK and White PSK insulations.
