Floors made from materials such as PVC, linoleum, rubber, etc., are called resilient floors. Resilient floors are sound proof and dust free and are used in libraries, offices, computer rooms, show room, etc. The three important resilient floors are: (i) PVC (Vinyl floors), Linoleum floor and Rubber floor, which are briefed below.
1. PVC Floor
The material in PVC floors is the thermoplastic binder which can be vinyl chloride polymer or vinyl chloride copolymer or both. The floor covering is backed with hessian or other woven fabric. Vinyl asbestos tiles have 40% of chrysotile asbestos fibre together with powdered mineral fillers and pigments. The thickness of normal PVC floor coverings are 1.5, 2.0, 2.5, 3.0 and 4.00 mm and the thickness of back floor coverings come in 2.0, 2.5, 3.0, 4.0 and 5.0 mm sizes. In roll form it is usually available in 1.0, 1.5 and 2.0 m and lengths of 10 m.
2. Linoleum Floor
Linoleum is a covering materials generally laid over wooden or concrete floors. Linoleum material is lubricated by mixing oxidised linseed oil with gum, resin, pigments, wood floor, cork dust and other filler materials. It is available as rolls of 2 or 4 m width with 2–2.5 m thick and both in plain and printed forms. Linoleum coverings are fixed to the sub-floor by means of suitable adhesive in order to have adequate bond and high durability. In some cases, it is nailed at the edges.
3. Rubber Floor
It is composed of natural rubber with various filling compounds. As the cost of rubber is high, their type of floor is expensive. They are produced in sheets and also in tile form. A sub-floor is essential.
