• Sound and fire-resistant floors separating compartments.
• Fire-resistant floors for high-risk areas.
• Water-resistant floors/ tiled floors on timber in bathrooms, toilets and kitchens.
• Underfloor heating on timber joists or steel beams.
• Finished floor ready to accept ceramic tiles, terrazzo, tiles natural stone or other floor coverings.
• Raised high-stability floors in shops, restaurants and offices.
• 'Inter-connected structure' for floors with inadequate strength and/ or rigidity.
• Structural, acoustic and fire-rated floors within light gauge steel load-bearing framed buildings.
• Concrete floors within modular buildings, traditional build, timber frame, SIPs or ICF building systems.
• Load bearing and vibration-proof plant room, dance hall and gym floors.

Lewis sheets are rolled, self-supporting, 16 mm deep, dovetailed profile steel reinforcement sheets which are used for shuttering and reinforcing lightweight concrete floors of limited thickness on timber or steel floor framing.

Features and benefits:

• Simple to use due to the special rolled profile.
• Can be laid directly onto floor joists or steel beams. Timber flooring may be omitted, resulting in savings on floor height and weight.
• Fire resistance ratings of 60, 90 and 120 minutes.
• Airborne and impact sound transmission values to Building Regulations (England and Wales), Approved Document E.
• Increased strength and rigidity of the interconnected floor system results in an extra load-bearing capacity of up to 30% for the floor as a whole.
• Water-resistant structural flooring.
• The profile allows air circulation essential for timber preservation.
• Total floor thickness as low as 36 mm, acoustic floors 50 mm.
• High load-bearing capacity combined with a low dead load of 0.9 kN/m² (at 50 mm).
