NOVA® Commercial Chimney System
NOVA® Commercial is a pre-fabricated, factory made twin-wall, insulated stainless steel chimney system. Each chimney element is fabricated with a fully welded 0.6mm 316L (1.4404:X2CrNiMo 17-12-2) stainless steel inner liner and a grade 304 (1.4301:X5CrNi 18-10) outer case. The 25mm annulus between the two walls is insulated with a high thermal performance pressure injected mineral fibre to a mean density of 250Kg/m3, offering rapid draught stabilisation while limiting thermal losses to the environment.
The joint is made with a multi-barb twist lock coupler, ensuring a fast build time with reduced labour costs. Condensate and pressure resistance if the application demands are undertaken by an elastomer seal positioned around the circumference of the inner liner, offering a pressure and leakage performance of P1 as defi ned under BS EN 1856-1.
Each joint once engaged is then fitted with a quick fit heavy duty locking band, offering additional strength to the joint whilst maintaining an aesthetic appearance.
