What it the difference between Welsh Penrhyn & Spanish Slate?
Let’s start by explaining what slate actually is. It’s an extremely fine-grained rock that was formed many millions of years ago from tightly compacted sedimentary clay deposits in the earth. They were generally found in seas that have since disappeared over time.
The overall composition of slate is made up of two lines of vulnerability: cleavage and grain. These lines make it really easy to split slate into the thin sheets that we now use commonly in slate roofing all over the world.
There are many types of slate roofing materials and styles, so it’s important that you are aware of the difference before installing slate on your roof
Welsh Penrhyn Roofing Slate
This is the Rolls Royce of slate and is the best on the market. Welsh Slate was extracted from all of the world’s best deposits which formed over half a billion years ago. Welsh slate is durable and really cost effective as you only have to maintain it every 10 or so years. It’s also 100% water resistant, will not be harmed by the suns UV light (which is great if your planning on putting Welsh Slate on your roof in tropical climates in Australia), is unaffected by pollution and will not damage if you live near the ocean.
Did you know that over 90% of all slate sold world-wide is quarried in Spain. Spanish slate is durable, really strong and will protect your home against the natural elements for many years. In fact, longer than you will probably live in the home. Spanish slate adds real value to your home due to its beauty and natural earthy looks.
So what’s the difference?
– Welsh slate is much older than Spanish slate and has been laying in the Earth much longer, therefore it’s properties are different.
– Welsh slate due to its age, is much denser which means it’s a lot stronger and durable than Spanish slate. Spanish slate is still durable but will discolour and degrade faster than Welsh Slate.
You have to find the right supplier and installer of slate. If you go for the cheaper option, in some cases this may not work in your favour as some Spanish slate that’s imported into Australia may be less durable and more susceptible to rusting, discolouration and cracking.
