● Commonality of ceiling and wall lining components

● General purpose lining

● Minimal connection to the structure

● Overcomes difficulties of background irregularities

● Can satisfy thermal performance and acoustic requirements

● Provides service void of 25mm - 125mm

● Ideal for refurbishing existing walls where:- wall surface quality

is poor- acoustic or thermal

upgrades are required- a cavity is required to

accommodate services, such as waterand waste pipes

Installation overview

For full installation details, refer to the British Gypsum SITE BOOK, available to download from www.british-gypsum.com

The required cavity depth up to a maximum of 125mm is

determined, and chalk lines marked to floor and ceiling to indicate

positioning of the Gypframe GL8 Track. Gypframe GL8 Track is fixed to

perimeters using appropriate fixings. Vertical lines are marked on

the wall at appropriate intervals to indicate Gypframe GL2 or GL9

Bracket fixing centres. Horizontal lines are marked at appropriate

centres to determine individual bracket positions. Brackets are then

fixed into position.

Gypframe GL1 Lining Channels are friction-fitted into the track,

extending if required. Bracket legs are bent forward and each leg

fixed to the Gypframe GL1 Lining Channel. The protruding bracket

legs are bent back to sit clear of the channel face.

At internal angles, a Gypframe GL1 Lining Channel is positioned tight

into the corner to provide support for the lining. Boards are fixed to all

framing members.

Openings

Gypframe GL1 Lining Channel is positioned either side of the door

opening and fixed to the Gypframe GL8 Track at head and base.

A section of Gypframe GL8 Track is cut and bent to form the head of

the opening. Short lengths of Gypframe GL1 Lining Channel are

positioned above the opening to provide additional support and to

maintain appropriate support centres. At window openings, Gyproc

edge bead is fixed to the perimeter of the window frame to protect

and retain the lining. See Construction details – 5.

The fire resistance and sound insulation performances are for imperforate partitions, walls and ceilings incorporating boards with all joints taped and filled, or skimmedaccording to British Gypsum’s recommendations. The quoted performances are achieved only if British Gypsum components are used throughout, and the Company’s fixingrecommendations are strictly observed. Any variation in the specifications should be checked with British Gypsum.

Design

Planning - key factors

The depth of the cavity is determined by the positioning of the

fixing brackets. Allow for a stand-off of 25mm - 75mm plus the

lining thickness for Gypframe GL2 Brackets, and 25mm - 125mm

plus the lining thickness for Gypframe GL9 Brackets. These

stand-offs are sufficient to correct irregularities normally

encountered in solid backgrounds. The stand-off will determine the

lining dimension required at door and window reveals and soffits.

Ceilings should be installed prior to installing GypLyner UNIVERSAL

wall linings. Any abutting partitions should also be installed prior

to drylining.

Cavity barriers

Building Regulations may require the provision of vertical cavity

barriers to long runs of lining. Minimum 12.5mm plasterboard, cut

to cavity depth and screw-fixed to the leg of Gypframe GL1 Lining

Channel, will provide a satisfactory cavity barrier.

Refer to section 10 – Cavity fire barriers.

Thermal performance

Uncontrolled air movement through the drylining cavity can result

in excessive heat loss from the building. The quoted U-values for

GypLyner UNIVERSAL wall lining are based on a sealed cavity between

the lining and the background. This is achieved in practice if the

abutting elements and the background are well fitted, and

junctions are sealed.

When the perimeter of the cavity is to be sealed by the drylining

contractor, the recommended method is to apply a continuous

fillet / ribbon of Gyproc Dri-Wall Adhesive or Gyproc Sealant to the

perimeter of the external wall and around any openings.

The designer should also specify a method of restricting air

movement around the perimeter of suspended timber floors, such

as the provision of a flexible seal between the floor and walls.

Good standards of thermal insulation can be achieved where

Gyproc ThermaLine laminates are specified as the lining. There

may, however, be a slight risk of pattern staining where

temperature, humidity, and soiling conditions are extreme.

Wall lining rigidity

Brackets should be positioned equidistant at maximum 800mm

vertical centres. Where there is a requirement for increased rigidity,

these support centres should be reduced accordingly, although

acoustic performance may be downgraded. Gypframe GL11

GypLyner Anchors are recommended for fixing brackets to the solid

background.

Services

The cavity between the metal framework and the background

facilitates the incorporation of services. Pipes and conduits should

be fixed in position before installing the framing.

When installing Gyproc ThermaLine laminates, the insulation

should not be chased to accommodate services. PVC covered cables

must not come into contact with polystyrene insulation. Suitable

isolation methods such as conduit or capping should be used.

Refer to section 3.5 – Service installations.

Fixtures

Lightweight fixtures can be made directly to the lining. Medium

weight fixtures should be made to Gypframe 99 FC 50 Fixing

Channel. Heavyweight fixtures (to BS 5234), such as wash basins

and wall cupboards, can be fixed using Gypframe 150 FC 90 Fixing

Channel.

Refer to section 3.5.2 – Service penetrations and fixing into

drywall systems.

Board finishing

Refer to section 13 – Finishing systems and decorative effects.
