Watti Block Chimney
This top-quality Finnish product is the right choice when you want a durable, heat-retaining flue solution for your home.
Watti chimney blocks are the result of years of product development and are made from 95% industrial surplus. The chimney block is a CE-marked eco-product, tested in Finnish conditions, and has been awarded the Key Flag label. The chimney blocks are designed for the northern market, where the most common fuels are wood, pellets, and wood chips. There is no need for separate internal pipes, as a fire-safe, heat-storing chimney block made from a single mass is the best option for our homes.
The chimney blocks are manufactured from start to finish on an automated production line at our factory in Oulainen.
The chimney is quick and easy to install because the blocks are dimensionally accurate, lightweight, and there is no need to handle separate internal pipes or insulation.
