FAQs

What type of flooring is this underlay suitable for?

This underlay is specifically designed for floating floor installations, including laminate and engineered wood flooring.

Can this underlay be used in bathrooms or kitchens?

Yes, the integrated silver layer provides moisture resistance, making it suitable for use in kitchens and bathrooms where dampness can be a concern, provided there are no significant water pooling issues.

How much noise reduction can I expect?

The underlay offers 19dB impact noise reduction, which significantly contributes to a quieter living environment by dampening footfall and impact sounds.

What is the thickness of the underlay?

The underlay has a thickness of 3.0mm.

How is the underlay packaged?

It is supplied in 1m(W) x 15m(L) rolls, packed in a PE bag.

What is the compression strength of the underlay?

The underlay has a high compression strength of 70kPa, ensuring it can withstand daily foot traffic without significant degradation.

Does this underlay have thermal insulation properties?

While it offers some thermal resistance, its primary benefits are acoustic and moisture resistance. For significant thermal insulation, specialized thermal underlays may be more appropriate.

Troubleshooting

Floor feels uneven or bumpy after installation.

Ensure the subfloor was perfectly level before laying the underlay. Check for any debris or wrinkles in the underlayment itself. Re-level the subfloor if necessary.

Noticeable noise transfer persists.

Verify that the underlay was laid without gaps or overlaps. Ensure the flooring planks are properly interlocked. For extreme noise reduction needs, consider a thicker or higher-rated acoustic underlay.

Moisture detected beneath the flooring.

Confirm the silver layer was facing upwards to provide moisture resistance. Ensure any significant water ingress has been addressed. If the subfloor is inherently damp, additional vapor barrier solutions may be required.

Pros and Cons

Pros

Enhances sound insulation, reducing noise pollution.
Provides robust support and durability due to high compression strength.
Offers effective moisture protection for the subfloor and flooring.
Easy to cut, handle, and install, suitable for DIY projects.
Versatile for use in various rooms, including high-moisture areas like bathrooms and kitchens.

Cons

Primarily suited for floating floor installations only.
May not offer sufficient thermal insulation compared to specialized thermal underlays.
The 3mm thickness might be insufficient for very uneven subfloors.
Requires a flat and dry subfloor for optimal performance.

Setup, Compatibility & Care Instructions

Setup:

Ensure the subfloor is clean, dry, level, and free from debris.
Unroll the underlay and cut it to size using a sharp utility knife.
Lay the underlay flat on the subfloor, ensuring no overlaps. The silver side should typically face upwards, check manufacturer instructions if available.
Trim any excess material around the edges.
Proceed with installing your chosen floating floor (laminate, engineered wood) directly on top of the underlay.

Compatibility:

Recommended For: Laminate flooring, engineered wood flooring, and other types of floating floors.
Not Recommended For: Glue-down or nail-down flooring installations, or as a primary vapor barrier without additional measures if extreme moisture is present.

Care:

Store rolls in a dry environment before installation.
Once installed, the underlay requires no specific maintenance, as its protective qualities are inherent.
Clean up any spills on the flooring promptly to prevent moisture from reaching the subfloor.
