Introducing New Zealand's First Cedar Rusticated System Tested to NZBC E2/AS1 VM1
JSC RusticClad, offers both wrap and rigid air barrier options along with the new JSC RusticClad batten profiles to complete an exclusive new range.
JSC Timber led the market developing a fully tested horizontal and vertical cavity system for Western Red Cedar in both Vertical Shiplap and Rusticated Cedar weatherboards formats.
JSC RusticClad is tested to NZBC E2/AS1 VM1 in respect to the requirements of clauses B1, B2 and E2 and gives a full Producer Statement-Design from an ACE accredited façade engineer.
Traditional and extremely versatile Rusticated Weatherboards offer unique horizontal negative lines that accentuate the grain structure and natural beauty of Western Red Cedar. Rusticated Weatherboards have evolved over recent years with new and innovative architectural profiles re-establishing the range to suit current new design methods.
