Delalande Velour
A heavyvelour material with exceptional acoustic absorption properties and rated M1 flame-retardant.
This yarn-dyed velour is available in an impressive range of attractive colours, and offers the advantage of very little difference in shade between production runs.
This FR polyester velour is particularly hard-wearing and is also washable, which makes it perfect for making curtains for use both indoors and outdoors.
Woven in 1.55 m widths, this velour lets you make banners larger than standard sizes normally available, while limiting the number of seams.
