CEDAR PANEL VERSUS PINE PANEL IN MARITIME CLIMATE

Cedar panels with the attractive deep reddish colour have been popular in Ireland for about 15 years now.

But how well does cedar look after a few years in our maritime climate?

We did a small testA piece of cedar panel was left out in the sun and rain for 1 month. The darker sections were treated with our clear and un-pigmented Jupex 45 tung-oil. We also tried our competitor Owatrol’s oil. They all seem to work reasonably well, the wood has a darker attractive red glow.

BUT the disturbing result is the cracking that appeared in the untreated cedar panel test board; After only 1 month cracks appeared where not treated with protective oil. The Irish weather with lots of sunshine AND lots of rain work like a rapid ageing test station.

By comparison, look at the grey timber of the decking behind the sample cedar board. This is 14 year old pine decking at our office. Oiled with pigmented Jupex 45 three  times in 14 years. Still pretty good.

The other attractive look of cedar, the aged silver grey look, is hard to get in our damp climate. In dry climates it is easy, just leave the cedar alone and it will become silver grey, just like an old barn in Siberia. But we are not in Siberia or dry Wyoming. We are in rainy Ireland and here it will go black from lichens and algae!

The problem is that by applying too much protective oil it goes even more black!

Some suppliers sell ageing agents to make the fresh cedar go grey faster. But how does that treatment prevent cracking?

This is as grey as pine becomes near the polar circle in the middle of Sweden after 150 years. Grey but also black. Light silver grey will only develop in really really dry and cold places like Siberia.

 

 

Our conclusion is that it must be better to use our standard treated scots-pine boards instead of the 4 times more expensive cedar panels in Ireland.

Some interior footage of home:

A word of warning when installing large panoramic windows. External shading must be provided to prevent over-heating. This is difficult to do in a wind-exposed coastal location as this.

Livingroom with a view: Large windows with electric automatic built-in shuttering to prevent overheating.

Our solution is NorDan-Screens. This is a new NorDan innovation with automatic remote controlled shutters integrated with the windows. We install windows with shuttering in the wall sections in our house-factory. The system can run automatically or via the remote control.
