Ventinox Collection TherMix Insulation Box for Ventinox and DuraFlex Series
Use to fill space between a liner and inside masonry chimney. Ready-mix formula cures into lightweight. semi hard mass that insulates the liner and dissipates the intense heat created in a chimney fire.
Ventinox components are made from either 316SS (VFT) or superferritic stainless steel (VG). Components feature an integral locking band, avoiding the use of pop rivets. Liners and components provide a penetration free top to bottom connection. When venting solid fuel heaters, Ventinox VFT must be insulated with either TherMix or ProFoil blankets to meet UL 1777 requirements. For all other applications, insulation is highly recommended for increased efficiency and draft performance.
