Types of underlay

If you choose for a foam based Envoy underlay, which is by far the most widely used, value for money and easiest to apply material, consider closely the type of foam you prefer:

Non-cross linked Polyethylene foam 

with its clearly visible cell structure gives the best value for money. It is easy to apply and 100% recyclable.

Cross linked polyethylene foam

comes at a higher price but has an extraordinary soft and smooth surface giving this specialty foam a high quality appearance.

Polypropylene foam

Polypropylene foam’s toughness results in a superb compression and creep resistance, which makes pp foam suitable to replace solid underlay materials. Polypropylene foam can withstand high temperatures however remains 100% recyclable.


The Envoy range offers you all of the above options, price categories, underlay performance levels. Moreover, we at Envoy have in house laminating capabilities to combine all of these foams to different types of films or other materials to create personalised exclusive products for your specific needs.
