Good quality productReview by Stephen Cain
We have now installed our woodburner using this chimney product.
Initially we had a couple of pieces arrive damaged but this was soon rectified by Greymetal and replacements arrived the next day.
I am very impressed with the quality for the price and it all fitted together with no problems at all and will keep us warm for many, many years. (Posted on 18/06/2015)
