AST Underlay

Here are all of our PU underlays! We stock a range to fit every budget! When deciding which underlay to go for the quality is in the density. Many people opt for the biggest overall thickness however a thinner underlay with a higher density will be much more durable. Take a look through our specifications and decide which is best for you! If you’re ever in doubt just give our staff a call and they’ll happily advise you on what’s best for your job. All our underlays are flame retardant and meet British standards.
