DW 25 OPTILIFE – new and attractive
The double-walled flue gas system is the “little brother” of the classic Raab DW and is specially designed for modern single-room fireplaces such as wood-burning and pellet stoves.
The quick-release clamping tape with capillary stop prevents moisture from entering the thermal insulation from the outside. The statically load-bearing outer shell impresses with its high stability. The freely expandable inner shell, together with the 25 mm joint-tight thermal insulation, guarantees low surface temperatures. The absence of these thermal bridges prevents cracking noises caused by temperature stresses during rapid heating.
Extensive accessories with moulded parts for almost all situations, fastenings, roof ducts etc. round off the system perfectly.
Suitable flue gas components such as draught restrictors and fine dust particle separators can be easily retrofitted or installed immediately. This saves fuel costs and protects the environment.
