Where should you fit Carpenter’s Super Gold 5mm?

The Super Gold is the thickest of the laminate underlays at 5mm and comes with the highest tog rating for providing significantly increased insulation.  So, it should be laid where you want added warmth underneath laminate or wood floor boards.

For example, where rooms have a cold concrete subfloor, it will help make the top flooring feel warmer, especially when walking on it with bare foot.

This underlay can be fit on either wood or concrete subfloor. It can be used in most areas of your property where laminate or engineered wood floor boards are being laid.

Between the 1.1tog and the 5mm thickness it makes a great choice for any homes that are naturally cold or get cold in the winter but you still want to fit laminate instead of carpet. What’s more, the Super Gold is absolutely essential where rooms are prone to dampness. That’s because it helps repel water and protect your flooring against excess moisture.

The high quality construction of the underlay ensures a solid, stable protection for the laminate floor or engineered wood flooring.

Ultimately, the Super Gold 5mm thick underlay makes the floor better to walk on while helping you save on heating bills. It can even smooth out small imperfections in the subfloor.

Where shouldn’t you fit the Super Gold 5mm?

Super Gold 5mm is not suitable for use with underfloor heating due to its high thermal properties. For underfloor heating, you’ll want to choose a high conduction product such as our Duralay Heatflow.

It’s also not suitable for fitting underneath carpet.

Made in the UK from 100% Recycled Materials

The Super Gold 5mm is made by Carpenters, a trusted manufacturer since 1948 based right here in the UK.

It’s constructed of 100% recycled PU Foam. It’s easy to cut with scissors and lightweight enough to handle round corners of the room – making it easy to fit it yourself or quicker for fitters to complete the job – in comparison to rubber products.

PU Foam are now the most popular for a few reasons. They are light weight and easy to handle. They are also made out of recycled materials and more economical to produce, keeping things green.

Why trust Carpenters UK for quality and longevity?

They have simply stood the test of time. That’s because many unbranded underlay products are found to be of poor construction or will deteriorate in a much shorter period of time. If the underlay deteriorates, then the laminate will need lifting and a new underlay fitted earlier than desired.

They have been innovating in the home comforts sector since 1948. With Carpenters you can be sure that you’re buying the highest quality and the longest lasting products.

Some people feel the need to budget for a lower cost underlay but this is the component that offers the most benefits.

While the laminate or wood is there to look and feel nice, the underlay is there for flooring protection, extra comfort and even insulation or sound reduction. Carpenters deliver on all of these.

At Underlay4u, we’re also committed to using British products that are recycled and manufactured right here in the UK.

  • Not suitable where underfloor heating is installed or underneath carpet
