British Gypsum Gypframe RB1 Resilient Bar

British Gypsum’s Resilient Bar can be used on multiple systems as an acoustic insulation bar. When installing the resilient bar it is essential to keep a couple of essential rules in mind. Firstly, the bar should only be used to meet acoustic performance specifications and screws should never penetrate the bar.  

Key Benefits: 

  • Improves sound performance of a build-up
  • Manufactured in 3000mm lengths  
  • Conforms to EN 14

Introduction

Gypframe profiles

Dimensional specifications data sheet This data sheet contains the dimensional specification of the following Gypframe components – Gypframe Studs, Gypframe Channels, CasoLine mf, GypLyner, ShaftWall, GypFloor silent, GypWall rapid dB Plus, Gypframe CurveLyner Channel, Gypframe Steel Angles and Gypframe Specialist Profiles.

Gypframe profiles are cold roll formed from DX51D + Z140 NA-C, utilizing the patented UltraSTEEL™1 process.

Cold Rolling and UltraSTEEL™

UltraSTEEL™ is a manufacturing process that alters the characteristics of plain steel, providing higher strength capacity at a lighter gauge. The process effectively hardens the steel by working it in strips with two mating rolls, which produce a dimpled surface and ribbing effect across the surface of the metal.

During the process, the effective thickness of the material is increased to that of the original thickness plus that of the ribbing. Example: Base gauge = 0.5mm : after UltraSTEEL™ process = 1.0mm.

Once the UltraSTEEL™ process has been applied, the base material is then passed through a series of contoured rollers which progressively form the steel into the required profile.

The number of rollers in the process will vary, depending on the complexity of the profile being rolled.

Service entries or tabs are pierced, either at the beginning or end of this process. The formed profiles are then cut to exact length, packed and then bundled ready for delivery.

UltraSTEEL™ is unique to British Gypsum and the Gypframe product range. Along with an aesthetic difference, UltraSTEEL™ provides the following additional benefits over plain steel sections.

— Improved yield strength
— Improved load carrying capacity
— Improved screw retention and strip out strength
— Improved resistance to screw pull-out

Standards

Gypframe metal products are produced to the European manufacturing standard EN 14195: 2005 and are manufactured under a quality system independently audited and certified as conforming to ISO 9001: 2008. The EN 14195: 2005 standard does not cover component design or system performance.

Do not assume products manufactured to this standard can be substituted, as system performance will be changed. UltraSTEEL™ is a registered trade mark of Hadley Industries Overseas Holdings Limited.

All British Gypsum system solutions listed in The White Book and The Site Book are covered by SpecSure®, a lifetime system warranty  designed to protect the integrity of British Gypsum specifications and deliver reliable performance, unrivalled technical support and peace of mind for everyone involved in the construction team.

The SpecSure® warranty is invalid if you change any component, as this will affect the system performance.
