| SLATE |
Slate is a fine-grained metamorphic rock that can be split into thin layers and mostly composed of chlorite, micas and silica. Natural slate is the most suitable material to isolate and protect your property, being respectful towards the environment.
Form the quarry EL PICÓN two types of slate are extracted: bluish-black slate and dark grey slate.
Characteristics:
- Minimum porosity.
- Low water absorption .
- Resistant to compression and to bending.
- Strong and easy to handle .
- Only one source of origin .
- Rustic appearance texture .
- Highly resistant to atmospheric conditions and to ageing .
- Very long lasting .
- Does not contain oxide or pyrite.
