Application
  • 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.

Description

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).
