Guide to Buying Underlay

Cosi Underlay

Carpet underlay

We recommend that every time you get a new carpet you replace your underlay. This is because new underlay cannot only increase the life of your carpet by 40%, but it also ensures the carpet sits properly and wears evenly.

Other benefits of having underlay and replacing it are: it improves the feel underfoot and reduce pile compression. It insulates against noise and heat loss and helps stop grit and dust being trapped in the carpet.


It is not just carpets that require underlay:

Laminate & Engineered wood underlay

Fibre board- is a lightweight, insulating board use for the floating installation of laminate, It is ideal for use on cold floors and is used to flatten uneven floors with imperfections up to 2mm. Wood and laminate flooring needs to be laid on top of a completely flat sub-floor this is why fibre board is the perfect solution. It is also environmentally friendly and biodegradable.

White Budget Ascotica underlay is used for insulating laminate floors. It is the cheapest option and can be used to sort of minor floor imperfections. It is 100% recyclable and has very good acoustic qualities.This type of underlay should only be used on wooden sub floors, it is not suitable for concrete as it has no water proof layer

Sliver- This underlay has an integral aluminium foil vapour barrier with a 200mm joint overlap. When used with vapour tape its acts as a waterproof membrane. It is suitable for correcting minor floor imperfections.  It is 100% recyclable and has very good acoustic qualities. This type of underlay should be used on concrete sub- floors, it can be used with wooden but there is no need for the extra cost for having the waterproof membrain. Therefore it better to go for the budget underlay as it has the same qualities minus the membrain. 

Solid Wood flooring does not require any underlay.
