Where should you fit Carpenters Midas 10mm?

The Midas 10mm underlay is a low cost underlay but still with a good insulation tog rating of 2.7 (tog usually ranges from 0.7 to 3.3) and good sound reduction properties of 36 db. It can be used in most areas of your property where you have carpet, bar from on the stairs.

This underlay can be fit on either wood or concrete subfloor and is a very popular choice for use in rental properties.

The medium density of 85kg/m3 provides a slightly softer feel than our higher density alternative, the Perfect Living 10mm. However, the 10mm thickness means it’s slightly firmer to walk on than the Midas 12mm.

This product offers great comfort and has excellent recovery characteristics from heavy furniture or chairs. That’s why it’s most suitable for areas of relaxation such as bedrooms, lounge, play rooms or even office bedrooms.

It has a woven top, which ensures a solid, stable protection for the carpet. If you have chosen a thinner carpet then this is the underlay for you to ensure that you still have the luxurious feel under foot.

Ultimately, the Midas 10mm carpet underlay is perfect for those on a budget who still want a high quality product. It adds a good level of comfort to your rooms while helping with insulation and sound reduction. It can even smooth out small imperfections in the subfloor.

Where shouldn’t you fit the Midas 10mm?

Midas 10mm is not suitable for the stairs due to its thickness. It’s also not suitable for use with underfloor heating due to its high thermal properties.

  • A thinner product, such as our Rich Step 9mm, would be best to use on your stairs.
  • For underfloor heating, you’ll want to choose a high conduction product such as our Duralay King

Made in the UK from 100% Recycled Materials

The Midas 10mm is made by Carpenters, a trusted manufacturer since 1948 based right here in the UK.

It’s constructed of 100% recycled PU Foam and has a medium density. 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 carpet 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 carpet 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 carpet is there to look and feel nice, the underlay is there for carpet 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.
