Specialist Foam Facings for Improved LF Absorption

We have developed a number of specialist facings for improved low-frequency absorption. This can often required when dealing with industrial noise issues, machine enclosures and fan casings etc.

We have managed to achieve 50% efficiency as low as 125Hz and 100% efficiency from 200Hz upwards.

The acoustic test data is shown on the right but it is a good idea to discuss your requirements with our technical team.

Facing options
FGA.BK Black or white weavelocked glass cloth
FPG.WH White polyurethane coated glass cloth
FPF.BK Black or white polyurethane film
FPPD Perforated black/white or grey PVC facing
FAG Aluminium foil laminated to glass fibre fabric
FOF Reinforced aluminium foil
FMP Metalised polyester film
FMP.SC Metalised polyester film with scrim
FVT.BK Black viscose tissue
All the above also available with a self adhesive peel off backing (SA)
