A2 – Insulated flue components
Use of flue components
Twin wall components are suitable for construction of new chimneys. They are installed on the outer or inner wall (chimney enclosed by walls). The components are resistant to high temperatures, condensate and weather conditions. Easily fitted.
Insulated components
Wool insulated flue components consist of three parts.Two pipes and insulation between them.The insulation is mineral wool, which is non combustible and resistant to high temperatures and has a stabile shape. Rubber gaskets and couplings guarantee water and fume tightness.
In addition to wool insulation, flue components are also produced with air insulation. IZO-AIR. Twin wall components are also manufactured with flanges.
