Full Pallet 90 x 20mm Boards
These External Wall Insulation (EWI) boards are designed for use with masonry, timber and steel frame constructions, offering fireproofing and insulation to walls and ceilings, both internally and externally.
Not only fire protection, but Marmox Fireboard is also a weatherproof barrier which will not degrade, however wet it gets! Also, being made from mineral wool, the boards provide very good sound decoupling and sound absorption properties.
Coated on the sides of the Marmox Fireboards is the unique Marmox honeycomb surface, which has been tried and tested for many years on our Marmox Multiboards. This is an ideal surface for applying a finish coat of render or plaster.
Key Benefits:
• Certified as A1 non-combustible.
• Acoustic insulation.
• Thermal insulation.
• Lightweight.
• Render or plaster.
• External or internal.
Applications:
• Use to fireproof any metal, masonry or wooden structures.
• Use as a fireproof alternative to plasterboard on internal walls and ceilings where fire protection & soundproofing is required.
• Ideal for fire surrounds.
• Provides thermal and acoustic insulation.
• To reduce thermal bridging on up-stands, used as a non-combustible inverted roof up-stand insulation board.
Sound Absorption: UKAS Testing.
Thermal Conductivity (λ value): 0.037W/mK.
Resistance to Fire Testing (Class A1 certification): Tests required passing in order to achieve Euroclass A1 certification:
- EN 1182 (Non-combustibility test - carried out by Efectis, 2018).
- EN 1716 (Bomb calorimeter test - carried out by BRE, 2022).
- EN 13823 (Single burn test - carried out by BRE, 2022).
Compressive Strength (to 10% deformation): 90kN/m (Equivalent to 90kPa or 9 tonnes/m²-Three times that of ordinary mineral wool).
R Values:
- 20mm = 0.5m²K/W.
- 100mm = 2.3m²K/W.
- 200mm = 4.7m²K/W.
Expansion Coefficient: 8 x 10-6K-1 (fairly similar to concrete).
