Flooring Core Types Singapore: SPC, WPC & LVT

SPC generally uses a dense mineral-filled polymer core, while WPC flooring commonly has a foamed composite core. Flexible LVT bends more readily and is often installed using adhesive. These constructions influence rigidity, underfoot feel and installation requirements, but core type alone does not establish scratch resistance, acoustic performance or suitability for a particular room. Compare the exact product specification, backing and installation instructions before choosing.

Two vinyl floors can share almost the same wood-look design yet behave differently under furniture, feel different underfoot and require different installation methods. The construction beneath the decorative surface helps explain why.

This guide focuses on what sits inside SPC, WPC and flexible LVT, and how to interpret those labels when comparing samples or quotations. For broader material selection, start with our Flooring Singapore: Complete Buying Guide.

Quick Takeaways

SPC and WPC describe core constructions; LVT is a broader flooring category.
WPC does not necessarily contain wood flour, despite the name.
Rigid-core flooring still needs a properly prepared, adequately supported subfloor.
Core construction, wear layer, surface treatment and backing have different functions.
Product-specific instructions matter more than a general recommendation based on the core acronym.

Understanding the Labels: SPC, WPC and LVT

SPC and WPC usually describe the structural core of a rigid vinyl flooring product. LVT, short for luxury vinyl tile, is a broader term. Suppliers also use it for plank-format flooring, and some ranges marketed as LVT have rigid cores.

That means “SPC versus LVT” is not always a comparison between separate material families. An SPC product may itself be described as rigid-core LVT.

In this guide, flexible LVT means bendable vinyl tiles or planks without the rigid core associated with SPC and WPC. Ask the supplier to identify both the construction and installation format whenever a quotation simply says “vinyl” or “LVT”.

For the practical buying differences, see our SPC vs LVT Flooring Singapore: Comparison.

SPC: A Dense Mineral-Filled Core

SPC is commonly expanded as stone plastic composite or stone polymer composite. Its core typically combines mineral filler, often calcium carbonate, with a polymer binder. Formulations vary between manufacturers and ranges.

The resulting construction is dense and rigid. It commonly gives the plank a firm feel and can contribute to resistance to indentation. However, the label does not make the floor dent-proof or establish how it will perform under every furniture foot or appliance wheel.

Concentrated loads, temperature, the complete plank construction and installation conditions still matter. A product’s documented performance and load restrictions are more useful than an unsupported claim that all SPC floors are the strongest.

Sound also depends on more than density. Attached backing, approved underlay, subfloor support and room furnishings all influence the sound of the installed floor.

Designer Tip: Use loose samples to compare colour, texture and visible construction. Tapping a sample against a table does not reliably show how the installed floor will sound. For acoustic comparisons, ask for test information covering the flooring with its specified backing or underlay.

WPC: A Foamed Composite Core

WPC is often expanded as wood plastic composite or wood polymer composite. In flooring, however, the name does not guarantee that the core contains wood flour. Some products marketed as WPC use foamed polymer composites without wood content.

The foamed structure can produce a more cushioned feel than a dense rigid core. How noticeable that difference is depends on the formulation, thickness and backing of the finished plank.

Resistance to concentrated loads varies too. Check the product’s intended applications and restrictions for furniture, appliances and rolling loads rather than assigning every WPC floor to bedrooms or excluding the entire category from kitchens.

WPC is discussed here as a construction category for comparison. Confirm current product availability with Monli before specifying it for a project.

Flexible LVT: A Bendable Layered Construction

Flexible LVT bends more readily than rigid-core flooring. Its construction varies by range, including the materials and reinforcement used beneath the decorative layer.

Many flexible LVT products are designed for glue-down installation. Loose-lay and other formats also exist, so flexibility alone does not establish the installation method.

Surface preparation is particularly important because imperfections beneath flexible flooring can become visible through the finished surface. Grout lines, adhesive ridges and rough patches may need treatment before installation.

Flexibility is not an advantage that allows an uneven substrate to be ignored. For glue-down products, substrate condition, moisture assessment and adhesive compatibility must also meet the installation requirements.

Read our Subfloor Preparation Guide for the checks that come before laying the floor.

Comparing the Three Constructions

Construction	General Characteristic	Key Checks
SPC rigid core	Dense mineral-filled construction with a generally firm feel	Indentation performance, temperature restrictions, backing and subfloor requirements
WPC foamed core	Foamed composite construction that can provide a more cushioned feel	Actual composition, approved applications and concentrated-load restrictions
Flexible LVT	Bendable construction, commonly available in glue-down formats	Installation method, subfloor smoothness, moisture conditions and adhesive compatibility

These are general construction differences, not guaranteed performance rankings. Two products within the same category can have different specifications and approved uses.

Core, Wear Layer and Backing: Different Jobs

A flooring quotation should distinguish the structural construction from the layers that protect the design or sit beneath the plank.

Core or structural body: Contributes to the plank’s rigidity and mechanical behaviour.
Decorative layer: Provides the printed wood, stone or other design in layered vinyl products.
Wear layer: Protects the decorative layer against abrasion.
Surface treatment: Contributes to surface characteristics such as cleanability and resistance to certain marks.
Backing: Forms the underside of the product and may include an attached cushioning layer.

A thicker total plank does not automatically have a thicker wear layer. Likewise, a dense core does not establish scratch resistance, and a water-resistant core does not prove that the entire installation is suitable for a wet area.

For a closer explanation of surface protection, read our Vinyl Flooring Wear Layer Guide.

Why Installation Can Change the Result

Rigid boards still need support

A rigid plank should not be treated as a bridge over hollows in the subfloor. The substrate must meet the manufacturer’s specified tolerances so that the installed flooring receives adequate support.

Movement over unsupported areas can stress the locking system. Correct preparation is therefore relevant to both flexible and rigid flooring, even though their preparation requirements may differ.

Floating floors need movement allowance

Many SPC and WPC products use click-lock floating installation. Where this applies, follow the specified expansion clearances, room-size limits and restrictions around fixed cabinetry.

Our Click-Lock Flooring Guide explains the mechanism, while the Floor Expansion Gaps Guide covers movement allowance.

Underlay must match the product

Do not add a softer or thicker underlay simply to change how a rigid floor feels. Some products already have attached backing, and additional cushioning may not be permitted.

Use only an assembly allowed by the flooring manufacturer. See our Flooring Underlay Buying Guide for the compatibility questions to ask.

Installer Tip: Obtain the installation instructions for the exact product code before confirming the floor build-up. “SPC” or “WPC” alone does not tell you the permitted underlay, expansion allowance, substrate tolerance or installation restrictions.

Choosing for a Singapore Home or Commercial Space

Start with the room’s actual demands rather than choosing a core first and trying to make it fit.

Space or Condition	What to Assess
Bedroom or lounge	Underfoot feel, furniture loads, maintenance and acoustic expectations
Home office	Suitability for chair castors, repeated rolling loads and any required floor protection
Kitchen	Appliance loads, spill management and installation around fixed cabinetry
Sun-exposed living room	Manufacturer restrictions for direct sunlight and temperature exposure
Commercial premises	Documented suitability for traffic, rolling loads and the planned cleaning routine

For a BTO, resale HDB flat or condo, also consider the existing floor, available build-up height and transition to adjacent rooms. Core type alone does not establish whether overlay is suitable.

Commercial projects need assessment of the complete flooring system. Our Commercial Flooring Buying Guide covers the broader specification process.

What to Request With Your Quotation

A useful quotation lets you identify the exact product and understand what is included in its installation.

Product identity: Manufacturer, range and product code.
Construction: Dense rigid core, foamed rigid core or flexible vinyl.
Separate measurements: Total thickness and wear layer thickness.
Backing: Whether it is attached and whether extra underlay is allowed.
Installation scope: Preparation, adhesive or approved underlay, trims and labour.
Intended use: Suitability for the room, loads and exposure expected.
Warranty: Coverage, conditions and exclusions for the selected product.

There is no dependable universal price order based only on SPC, WPC and flexible LVT. Compare the complete installed scope, especially where one option requires more preparation than another. Our Flooring Cost Guide explains the main budgeting factors.

FAQs

Are SPC, WPC and LVT three separate flooring categories?

Not exactly. SPC and WPC usually describe rigid-core constructions, while LVT is a broader vinyl flooring term. Ask whether an LVT product is flexible or rigid and which installation method it requires.

Does WPC flooring always contain wood flour?

No. Some flooring products marketed as WPC use foamed polymer composites without wood flour. Check the manufacturer’s construction details rather than relying on the acronym.

Is SPC always the most dent-resistant choice?

Dense construction can contribute to indentation resistance, but there is no universal ranking covering every product. Compare documented performance and check restrictions for concentrated loads, furniture and appliances.

Can rigid-core flooring hide an uneven subfloor?

It still needs a substrate within the manufacturer’s tolerances. A rigid core does not replace preparation or make unsupported areas beneath the planks acceptable.

Which construction is quietest underfoot?

Core type alone cannot answer that. Backing, approved underlay, subfloor support and the room affect sound. Compare acoustic information for the relevant flooring assembly where available.

How can I confirm the core type of a sample?

Ask for the exact product code and manufacturer’s datasheet. A cross-section can help illustrate construction, but appearance or a tap test should not replace the documented specification.
