Phyllite is harder and longer lasting than natural slate and it has a colour and sheen like no other. Check for four things and you'll have a product that will elevate any project
Architects understand the power of a well chosen material. Specifying the right roof isn't just about aesthetics – it's about ensuring longevity, low maintenance and environmental responsibility.
Phyllite might not be as well known as slate, but it's quickly becoming one of the most sought-after materials of its kind.
It offers lifespans of over 100 years and low maintenance. It is aesthetically pleasing and it’s got a long track record of being approved by planners and conservation officers.
So how can architects ensure they are specifing the best possible phyllite product for their roofing project?
4 ways to spot quality phyllite
- Minimal water absorption Water getting into cracks can freeze, expand and damage the slate. Opt for W1 rated slate, which absorbs less than 0.6 per cent of water.
- Low chalk content Too much chalk (calcium carbonate) can lead to unsightly white patches and flaking over time. S1 material has the lowest chalk content, making it the most desirable choice.
- Low risk of rusting Pyrite, also known as fool's gold, can react with oxygen and cause rust. This not only looks bad, but can weaken the material. T1 rated slate has a low risk of rusting or changing colour.
- Tested at source For ultimate protection, consider slate tested to the rigorous French standard NF 228. Unlike British testing, which relies on quarry-submitted samples, NF 228 tests the slate directly at its source.
