within buildings. Many years' experience in soundproofing, combined with well proven and tested products, provides a

Introduction Acoustilay and
Maxiboard have been designed to
upgrade the sound insulation of

constructions to achieve the
standards of Building Regulations
Approved Document E (2003) or
simply to upgrade the existing
insulation for personal comfort.
Acoustilay acoustic flooring
underlay system
Description Acoustilay combines
excellent airborne (TV, music,
speech) and impact (footsteps,
moving furniture) sound insulation
with all the qualities expected of a
luxury underlay. It can be easily
formed and shaped with a standard
trimming knife, and, with a thickness
ranging from 10 mm to 22 mm,
minimises the increase in floor level.
Acoustilay is available in 4 different
grades and is suitable for use on
timber and concrete floors and can
be installed under most floor
finishes. All accessories required to
facilitate installation are provided.

performance figure set out by
Building Regulations Approved
Document E (2003). The resilient
foam layer bonded to the barrier
membrane produces a high
performance system that reduces
impact sound and acts as a luxury
underlay under carpet.
