How thick, how dense and which rooms is the Extra Step Heavy Duty Contract 6mm Underlay for?

The Extra Step Heavy Duty Contract Underlay is 6mm and very dense (180kg/m3) so it’s best suited for contract locations where durability is the priority.

It is suitable for the European domestic market where thinner, denser products are required and it also conforms to the International Maritime Organisation’s standards.

Extra Step can be used throughout a building, including the stairs, so it’s a great economic choice.

If you are looking for a domestic product with a softer feel, we wouldn’t recommend this heavy duty option. Instead go for something like Carpenter’s DeepStep 11mm.


How insulated is the Extra Step 9mm Carpet Underlay?

The Extra Step 9mm has a tog rating of 1.5. For a product that’s 6mm thick this is a great rating and will certainly help to retain warmth.

As well as helping to retain warmth, the Ultra Step 9mm can also act as a barrier against cold air coming up through draughty floorboards and it can also prevent the chill of a concrete subfloor coming through the carpet above.

What is Extra Step Heavy Duty Contract 6mm Underlay made from and who makes it?
