The Lewis system works very well with screeded underfloor heating and cooling systems, allowing them to work more efficiently than without the sheets in place.

LEWIS provides a number of solutions for renovations and conversions as well as with new build projects using all types of build including traditional, timber or steel frame as well as new methods of build such as ICF and modular off site construction and mezzanine floors.

Apart from standard domestic separating floors, Lewis Deck provides exceptional solutions for bespoke acoustic floors within live music venues, night clubs, restaurants, recording studios, recreational performance studios, specialist test labs, plant rooms and many other commercial applications.

• Simple and easy to install
• Fire ratings up to 120 minutes
• New build or renovation/ conversion
• Suitable for liquid screeds and fine grade concrete
• Suitable for use with ceramic or stone tiles
• Great for wet rooms
• Span joists (up to 2.5m centre to centre) or lay direct to existing floor

A Lewis Deck composite floor consists of the Lewis cold rolled steel sheet covered with a relatively thin layer of C20/25 fine grade aggregate concrete or CA25/ F4 free flowing, self levelling liquid screed.

During the curing period the Lewis Deck acts as shuttering, but once the concrete/ screed has cured, locking into the Lewis Deck, it forms an extremely strong, composite, structurally sound floor, i.e. it becomes reinforcement for the concrete/ screed. The use of fine grade aggregate concrete can also provide a monolithic finish to provide a “finished floor” option. The overall depth of a Lewis composite floor can be relatively thin – 52 mm in most cases (with UFH pipework).
