PVC Roll & Sheet Vinyl Flooring in India: Homogeneous vs Heterogeneous Rolls, Heat-Welded Seamless Floors for Hospitals, Labs & Schools — Types, Cost & Care

Walk into any modern hospital, diagnostic lab, operation theatre or good school in India and look down: that smooth, jointless, slightly cushioned floor that curves up the wall instead of meeting a skirting tile is almost always PVC roll flooring — sheet vinyl supplied in wide rolls, glued to the screed and then heat-welded seam to seam into one continuous, water-tight, hygienic surface. It is a different animal from the click-together LVT and SPC planks most homeowners now know: those are rigid tiles with joints, while roll vinyl is a soft, weldable sheet whose whole reason for existing is to have as few joints as possible.

This guide is written for architects, project managers, facility teams and specifiers. It explains what homogeneous and heterogeneous vinyl actually are, why a welded, coved, seamless floor is what infection-control standards want, what the conductive, anti-static and anti-bacterial grades do, how it is installed on Indian sites, where it suits and where it does not — and how it sits against LVT, SPC and budget plank vinyl, at ₹60–250 per sq ft.

What PVC roll (sheet vinyl) flooring is

PVC roll flooring is polyvinyl chloride compounded with plasticisers, stabilisers, fillers and pigment, then calendered or cast into a continuous flexible sheet and delivered in rolls — typically 2 metres wide and 20–25 metres long, 2 to 4 mm thick. On site the roll is unrolled, cut to the room, bonded to a smooth screed with adhesive, and the joints between adjacent sheets are then chemically or hot-air welded so the finished floor behaves as one impervious membrane.

That last step is the whole point. A floor made of discrete tiles — ceramic, vitrified, even LVT — has hundreds of metres of joints where water, blood, spills and bacteria can sit, and grout that stains and degrades. A welded sheet vinyl floor turns those joints into fused, sealed lines flush with the surface, and when the sheet is "coved" — turned up the wall 75–100 mm with a cove former and finished with a capping strip — there is no floor-to-wall corner to trap dirt either. The result is a continuous, washable, water-tight tray that you can flood-mop and disinfect. This is exactly why it dominates clinical, laboratory and pharma environments.

Studio Matrx groups sheet vinyl with the resilient floors — soft, slightly cushioned, sound-damping surfaces — alongside rubber flooring and the plank vinyls. It is one branch of the larger vinyl flooring family and a core entry in the specialty flooring guide.

Roll vinyl vs LVT and SPC planks — don't confuse them

People say "vinyl flooring" and mean three very different products. Getting this straight is the first job of any specifier.

Roll vinyl is chosen when you need a true seamless, weldable, hygienic membrane — something planks with open joints can never be. LVT and SPC are chosen for looks, dry-laying convenience and a tile-like rigidity. If your brief contains the words "infection control", "wash-down", "static dissipative" or "wet process", you are almost certainly specifying roll vinyl, not planks.

Homogeneous vs heterogeneous: the two families

All sheet vinyl falls into one of two build-ups, and the choice drives both performance and price.

Homogeneous vinyl

Homogeneous sheet is a single, uniform layer of PVC with the colour and pattern running all the way through its thickness (usually 2 mm). Because the wear surface is the whole sheet, you can grind and re-polish it many times over a 15–20 year life, and a scratch does not reveal a different colour underneath. It is the workhorse of operation theatres, ICUs, laboratories and heavy-traffic hospital corridors precisely because it is renewable and tough. The trade-off: it comes in solid and lightly speckled colours, not realistic wood or stone prints.

Heterogeneous vinyl

Heterogeneous sheet is built in layers, like the plank vinyls: a clear PVC wear layer on top, a printed decor film carrying the design, a glass-fibre reinforcement for stability, and a backing (often a foam or compact base that adds comfort and acoustics). This lets it carry photographic wood, stone and abstract designs and offers a cushioned, quieter underfoot feel — so it suits schools, offices, clinics, paediatric and aged-care wards, hospitality and homes. Its wear life depends on the thickness of that top clear layer (commonly 0.5–0.7 mm for commercial grades), measured to EN 660 / "T-class" wear ratings.

The diagram below shows both build-ups side by side, with the welded seam and coved skirting detail that defines the system.

The performance grades: anti-bacterial, conductive and anti-static

Beyond the homogeneous/heterogeneous split, sheet vinyl is specified by the technical grade the room demands.

• Anti-bacterial / bacteriostatic — the wear surface (and often a PUR factory finish) carries a treatment that inhibits bacterial growth and resists staining. Standard for wards, clinics, kitchens and food areas. The PUR factory coating also removes the need for polishing and makes daily cleaning a plain damp mop.
• Conductive (CD) and dissipative / anti-static (ESD) — these grades drain static charge to earth through a conductive backing and copper earthing strips bonded into the floor. Conductive vinyl (low resistance) is mandated in operation theatres and anaesthetic areas where static sparks near oxygen are a hazard; static-dissipative grades (higher, controlled resistance) protect electronics manufacturing, server rooms, BSL labs and clean rooms. For a full treatment of static control floors, see the anti-static and ESD flooring guide.
• Acoustic / cushioned — a foam-backed heterogeneous sheet that cuts impact sound by 15–19 dB, used in multi-storey hospitals, schools and offices where footfall noise carries.
• Safety / anti-slip — vinyl with embedded silicon carbide or aluminium-oxide grit and a higher slip rating (DIN 51130 R10–R11, or barefoot class B/C) for bathrooms, wet labs, kitchens and wash-down areas. This complements the anti-slip wet-area flooring guide.

Type, use and cost in India

Pricing is for material only unless noted; add 18% GST, adhesive, screed correction, welding rod, coving formers and skilled labour. Ranges are indicative and vary by city, brand and order size.

Installed cost is typically 30–60% above the material rate once screed levelling, adhesive, welding and coving are added — and the screed quality often costs more than people expect, because sheet vinyl is unforgiving of an uneven base. Compare these numbers against the wider flooring cost per square foot guide, and size a job with the flooring cost calculator.

Leading sheet-vinyl brands available in India include Gerflor, Tarkett, LG Hausys, Armstrong, Forbo, Polyflor and Responsive; many hospital projects specify imported homogeneous and conductive lines because of the BIS/EN compliance documentation they carry.

How PVC roll flooring is installed

A welded sheet floor is only as good as its screed and its welder. The sequence on an Indian site is exacting.

Step 1 — Prepare a flat, dry, smooth screed

The sub-floor is the make-or-break. It must be flat (typically within 3 mm under a 2 m straightedge), fully cured, dust-free and dry — residual moisture in a green slab will blow the adhesive bond and lift the sheet. On uneven slabs a self-levelling compound is poured first. This step links directly to good floor screed and mortar-bed practice; skimping here is the single most common cause of bubbling vinyl in Indian projects.

Step 2 — Acclimatise, set out and cove

The rolls are left flat in the room for 24–48 hours to relax and reach room temperature so they do not shrink after laying. Sheets are set out to minimise the number of seams and to run seams away from doorways and wet points. Where coving is specified, a cove former (a quadrant fillet) is fixed into the wall-floor angle so the sheet can be turned up the wall in a smooth curve.

Step 3 — Bond with adhesive

The sheet is folded back and the correct adhesive — acrylic dispersion for general areas, or a conductive adhesive over copper earthing strips for CD/ESD floors — is troweled onto the screed. The sheet is laid into the wet adhesive and rolled with a heavy floor roller to expel air and ensure full transfer. Edges are scribed tight to walls and the cove is dressed up and capped.

Step 4 — Groove and weld the seams

Once the adhesive has cured, every seam (and any coved corner) is mechanically grooved out to a controlled depth, and a matching PVC welding rod is melted into the groove with a hot-air gun. The proud rod is then skived flush in two passes with a spatula knife. Done properly, the weld is a fused, watertight line slightly visible as a fine bead — this is what turns separate sheets into one impervious floor. Cold chemical welding is used for some heterogeneous products instead of hot-air.

The welding is the skilled part: a poor weld either leaves a gap (defeating the hygiene purpose) or a burnt, brittle bead. Hospital and OT work should always use a trained sheet-vinyl crew, not a general tiling gang.

Where PVC roll flooring suits — and where it does not

It is the default specification for healthcare and laboratory work: operation theatres (conductive), ICUs, wards, corridors, diagnostic labs, pharma and food-process areas, dental and veterinary clinics. It is equally strong in schools and creches (warm, quiet, soft on falls), offices, server and control rooms (ESD), and as a fast, cheap, water-resistant floor for rentals, hostels, clinics-on-a-budget and temporary fit-outs.

It is a weaker choice where a premium natural look is wanted in a home (LVT, engineered wood or stone read better), where very heavy point loads or hot trolleys are dragged daily (it can dent and scorch), and in unconditioned outdoor or terrace settings (UV and heat degrade plasticised PVC — use the outdoor flooring options instead). Cheap thin rolls in Indian rentals also telegraph every screed defect and tear at edges, which is why the screed and a minimum 2 mm sheet matter.

On sustainability, PVC is a plasticised plastic and not biodegradable, though phthalate-free formulations, recycled-content backings and take-back schemes now exist from the major brands; weigh it against the alternatives in the eco-friendly flooring guide.

Care and maintenance

Daily care is simply dust-mopping and damp-mopping with a neutral pH cleaner — the factory PUR finish on modern sheet vinyl means no waxing or polishing for years. Spills wipe up; the seamless welded surface means nothing soaks into joints. Avoid abrasive pads, solvents and very hot water, which dull or soften the surface. Use felt pads under furniture and non-staining castors, because rubber feet and dark rubber mats can leave permanent marks on light vinyl. Homogeneous floors that have lost their sheen after years of traffic can be machine-buffed and re-finished rather than replaced — one of their key advantages. General routines are covered in the floor cleaning guide.

How it compares — and when budget roll vinyl is the right call

At the budget end, a 1.5–2 mm heterogeneous roll at ₹60–110 per sq ft is one of the cheapest hard-wearing, water-resistant, fast-to-lay floors available in India — which is why it is the standard for rentals, hostels, budget clinics and quick commercial fit-outs. You sacrifice the premium look and the re-grindable longevity of homogeneous sheet, but you get a hygienic, mop-clean surface installed in days.

At the technical end, homogeneous and conductive sheet at ₹130–250 per sq ft buys something LVT and SPC planks simply cannot deliver: a truly seamless, weldable, static-controlled, infection-control floor. The decision is therefore rarely about price alone — it is about whether the room needs a seamless welded membrane (specify roll vinyl) or a good-looking dry-laid plank (specify LVT or SPC). To weigh the whole resilient-floor field, use the specialty flooring selector and the specialty flooring guide.

Frequently asked questions

Is PVC roll flooring the same as the vinyl planks sold in homes?

No. Roll (sheet) vinyl is a wide, flexible sheet that is glued and heat-welded into a near-seamless floor, used for hospitals, labs and schools. The planks most homes buy are rigid LVT or SPC tiles with click or glued joints that are never welded. They share PVC chemistry but solve different problems — seamless hygiene versus a dry-laid decorative floor.

Why is sheet vinyl welded and coved in hospitals?

To remove the places dirt and bacteria hide. Heat-welding the seams turns every joint into a fused, watertight line, and coving the sheet up the wall removes the floor-to-wall corner. Together they create a continuous washable tray you can flood-mop and disinfect — which is what infection-control and OT standards require, and what tiled floors with grout cannot offer.

What does conductive or anti-static PVC flooring do?

Conductive (CD) and dissipative (ESD) grades drain static charge to earth through a conductive backing and copper earthing strips. Conductive vinyl is mandated in operation theatres where static sparks near oxygen are dangerous; dissipative grades protect electronics manufacturing, server rooms and clean rooms. See the anti-static and ESD flooring guide for the resistance classes and earthing detail.

How much does PVC roll flooring cost in India?

Material runs about ₹60–250 per sq ft: ₹60–110 for thin budget heterogeneous rolls, ₹110–200 for cushioned commercial sheet, ₹130–230 for homogeneous, and ₹180–250+ for conductive and ESD grades, plus 18% GST. Installed cost is usually 30–60% higher once screed levelling, adhesive, welding rod, coving and skilled labour are added.

Can PVC roll flooring be used in homes and wet areas?

Yes for budget homes, rentals and indoor wet zones — a 2 mm+ sheet with welded seams is water-tight and easy to clean, and safety grades add anti-slip grit for bathrooms. It is not for unconditioned terraces or open outdoor areas, where UV and heat degrade plasticised PVC; choose an outdoor flooring material there instead.
