I was looking for good quality skirting for a new orangery that inevitably will be subject large temperature changes. Traditional kiln-dried timber is good but can't compare to mdf boards for thermal stability and after just a short time can lead to warping and gaps developing between wall and board. Mdf is far better and this product is a good, near match for the original skirting in my Edwardian house. The only reason I have not given this product a full 5 stars is that the routing of the mdf to create the moulding design at the top of the board has led to a rougher surface than expected and will prove tricky to keep clean over time.
