Cedar is a durable softwood timber usually sourced in North America. Its colour is brownish red and because of its durable properties it has been used in recent years as a cladding for buildings. In my opinion it has been used excessively and usually has not been protected against the elements. It therefore usually looks terrible after wet weather. It is worth considering whether this cladding is more suitable for buildings with a dryer climate than Ireland or the UK.
Even a durable timber like cedar needs to be sealed against water ingress to protect it. All timber will absorb moisture in damp conditions and release it again in dry weather. The recent craze for using cedar cladding hasn’t extended to understanding that the timber must be sealed. As a result, buildings clad thus, can have a really miserable look after wet weather, having a dark, wet and blotchy appearance. It is hard to think of a cladding that would seem shoddier after wet weather. See photographs below, it is worth noting that both of the buildings below have been completed within the last three years. See also a suppliers viewpoint in comments section below.
