Barrier Mats

U5

Description
Barrier Mats are manufactured from a durable, flexible polymeric material.
They are designed to add mass to building elements, equipment or automotive components, acting as acoustic barriers to reduce noise transmission.
Barrier Mats are available in rolls or sheets and can be die-cut to size and shape.

Design and Application

U5 Is a highly flexible, polymeric barrier mat.It is used extensively in the building services industry to add mass and reduce noise break out from pipes, ducts and other equipment, and by automotive manufacturers to improve the sound insulation of vehicle floors and bulkheads.

T5 Is a highly flexible, polymeric barrier mat with a Class ¡®o¡¯ foil facing on one side.It is used extensively in the building services industry to add mass and reduce noise break put from pipes, ducts and other equipment, and by automotive manufactures to improve the sound insulation of vehicle floors and bulkheads.

BM 5N & 10N Are highly flexible, polymeric barrier mats incorporating additional mineral fillers to increase the product¡¯s
mechanical strength and durability.

They are used extensively in the building industry to improve the sound insulation of existing partition walls. They are particularly effective at reducing Coincidence Dip on lightweight composites e.g. plasterboard.

Operating Temperature
Barrier Mats can be used at continuous operating temperatures up to 65¡æ.

Fire Performance
T5 Complies with the Class ¡®O¡¯ requirements of the Building Regulations, when tested to BS476: Pare 6: 1981 and Part 7: 1987
U5, BM 5N and BM 10N meet the requirements of FMVSS 302/ISO3795.

Application and Fixing
When fixing Barrier Mats to mechanical services they should be wrapped around pipes and ductwork incorporating a minimum 50mm overlap on all joints. They should be supported with non-metallic banding and/or an outer layer of wire mesh or similar.
When applying to other substrates such as timber, steel or aluminium, Barrier Mats should be fixed into position using 1099 contact adhesive available from Hodgson & Hodgson Group Ltd. Where more than one mat is required, tightly butt joints together.
