A frequent query we receive at Vinyl Flooring Direct is whether an underlay is necessary when installing SPC flooring. The emphatic response is yes, and in this enlightening article, we will delineate the rationale behind this recommendation. If you’re considering SPC flooring, we can forego the details of this flooring solution’s composition and concentrate on the advantages of pairing SPC with a suitable underlay.
The Advantages of SPC Flooring Specifically with an Underlay
A Much-Needed Cushioning Effect – Owing to its stone plastic composite or stone polymer composite (SPC) makeup, these floorboards are exceptionally rigid, which can lead to a harsh underfoot sensation. Introducing an underlay can provide a cushioning effect, resulting in an incredibly sturdy floor that is also comfortable to walk on.
A Quieter Walking Experience – SPC flooring typically comes in thinner profiles ranging from 4mm to 10mm. This means that footfall noise can echo within the room and even to lower floors. An underlay can significantly reduce walking noise, enhancing the tranquillity of your space.
Ensures a Smooth and Level Floor – The relatively slim profile of SPC flooring means any subfloor irregularities will be immediately perceptible, both tactilely and visually. In reality, unless the subfloor is brand new, it’s likely to have some level of imperfections, despite efforts to create a smooth base. An underlay can mitigate these imperfections, resulting in a seamless and level surface.
A Warmer Walking Experience – Certain subfloor materials, such as concrete, can transmit cold, which is particularly noticeable with SPC flooring due to its thin profile. An underlay acts as an ideal barrier between a cold subfloor and the floorboard, enhancing comfort.
Insulation Enhances Energy Efficiency – Heat loss is a common issue with most types of flooring, except for thick carpets. Generally, the thinner the flooring, the greater the heat loss. SPC flooring is notably thin, with an average thickness of 5mm, compared to 8mm for laminate and 12mm for wood, making insulation paramount. Incorporating an underlay can increase the overall thickness of the floor and improve energy efficiency.
As initially indicated, SPC flooring should ideally be complemented with an underlay. In fact, the importance of an underlay to the success of the overall project is such that many manufacturers, such as Supremo, have launched ranges with a built-in underlay. This move underscores the necessity of an underlay with SPC flooring, far from being an optional addition.

FAQ
Is an underlay necessary for SPC flooring installation?
Absolutely, an underlay is crucial when fitting SPC flooring. It not only provides a layer of cushioning for enhanced comfort but also contributes to the durability and stability of the flooring.
How does an underlay improve the walking experience on SPC flooring?
An underlay minimises noise transmission, making your steps quieter, and provides a softer surface to walk on, mitigating the inherent rigidity of SPC flooring.
Can an underlay correct subfloor imperfections?
Yes, an underlay can smooth out minor irregularities in the subfloor, ensuring a more level and visually appealing finish for your SPC flooring.
Does an underlay affect the temperature of SPC flooring?
Indeed, an underlay acts as a thermal barrier, especially over cold subfloors like concrete, enhancing the warmth and comfort underfoot.
Why is insulation important with SPC flooring?
Given the thin nature of SPC flooring, it can be prone to heat loss. An underlay adds a layer of insulation, aiding in maintaining energy efficiency within the space.
