DriLyner
DriLyner systems provide simple and effective techniques
for fixing Gyproc plasterboards or Gyproc thermal
laminates to brick, block, and concrete walls. They can be
used in all building types in both new-build and
refurbishment work.
The DriLyner MF system facilitates the fixing of Gyproc
plasterboards or thermal laminates to lightweight MF10
metal furring channels, which are bonded to masonry wall
surfaces using Gyproc Compound. When using the DriLyner
MF system, care must be taken with solid in-situ walls, solid
concrete panel walls, heavy block, or no-fines walls, as
thermal bridging may occur which could result in screwhead pattern staining.
DriLyner BASIC, DriLyner TL, and DriLyner MF systems all use
the principle of gypsum adhesive dabs to bond boards
directly to the wall. Secondary mechanical fixings are
required when installing laminates.
The DriLyner RF system provides a method of fixing boards
directly to solid walls, including directly to plastered walls
in a refurbishment situation, using blobs of Gyproc Sealant.
The DriLyner RF system should only be used on suitably
pretreated dry, sound, plastered wall surfaces, or fair-faced
concrete, brick, or block walls, without major irregularities.
DriLyner BASIC - dry lining using Gyproc Wallboard, Gyproc
DuraLine or Gyproc Moisture Resistant.
DriLyner
TL
- dry lining using Gyproc Thermal laminates.
All DriLyner systems provide a low maintenance, low
thermal capacity lining which responds quickly to heating
and provides early room comfort conditions. The linings
are quick to install with minimum drying time. Services can
be incorporated with minimum chasing.

Note: If Gyproc WallBoard Duplex is to be installed using a
DriLyner method, it should only be fixed in the
DriLyner MF system.

INSTALLATION OVERVIEW - DriLyner BASIC and TL systems
Setting out lines are marked on the floor and ceiling
allowing for high spots, a 10mm drylining cavity and the
thickness of board.
The wall is marked with lines at 900mm or 1200mm centres
to indicate board positioning. A continuous fillet / ribbon of
Gyproc Compound is applied to the wall perimeter and
around services and openings as board fixing proceeds.
Drylining is commenced from a window/door reveal or
internal angle and adhesive dabs applied in three or four
rows (as appropriate) to receive the first board, together
with intermediate dabs at ceiling level and a continuous
band of adhesive at skirting level. The boards are
positioned with the bottom edge resting on plasterboard
packing strips.
Boards are ‘tapped’ into position, lifted tight to the ceiling
using a footlifter and supported until the adhesive sets.
Further boards are installed, lightly butted together, to
complete the lining.
When installing Gyproc ThermaLine laminates in the TL
system, two Gyproc Nailable Plugs are inserted per board
(after the dabs have set) as secondary mechanical fixings,
normally located within the tapered edges so that they are
concealed when the system is finished, at mid height. The
fitting of Gypframe Skirting Plates over the bottom edge of
boards during installation provides a ground for subsequent
skirting fixing.
INSTALLATION OVERVIEW - DriLyner RF system
The wall is marked with lines at 900mm or 1200mm centres
to indicate boardpositioning. Drylining is commenced from
a window / door reveal or internal angle. Gyproc Sealant is
gun-applied to the wall in blobs at 300mm centres.

INSTALLATION OVERVIEW - DriLyner MF system
Setting out lines are marked on the floor and ceiling
allowing for high spots, a 20mm dry lining cavity and the
thickness of board. The wall is marked with lines at 600mm
centres to indicate Gypframe MF10 Channel positioning. A
continuous fillet / ribbon of Gyproc Compound is applied to
the wall perimeter and around services and openings as
board fixing proceeds. Dabs of Gyproc Compound are
applied progressively to the wall to each vertical line.
Gypframe MF10 Channels are located onto the adhesive
dabs and ‘tapped’ into position.
Further vertical Gypframe MF10 Channels are adhesive fixed
to complete the run of wall. Horizontal channels are
similarly located at the head and base. Board fixing can
proceed once the adhesive has fully set.

At angles and reveals, Gypframe MF10 Channels are
installed close to the corner to provide support. Door and
window openings are framed with Gypframe MF10
Channels. At window openings, the channel at the head
forms a ground for fixing curtain track. Where a partition
abuts, an additional Gypframe MF10 Channel is installed to
provide a fixing ground.
When installing Gyproc ThermaLine laminates, a continuous
bead of Gyproc Sealant is gun-applied to the Gypframe
MF10 Channels just prior to positioning and screw fixing
the boards.
Boards are positioned with the back against the
Gypframe MF10 Channels and bottom edge resting on
plasterboard packing strips and lifted tight to the ceiling
using a footlifter.
Addtional packing strips are inserted at the base to wedge
the board in place. Boards are screw-fixed to all Gypframe
MF10 Channel supports.

PERFORMANCE
Environmental
DriLyner systems are unsuitable for use in areas subject to
continuously damp or humid conditions.
Plasterboards are not suitable for use in temperatures
above 49ºC, but can be subjected to freezing conditions
without risk of damage.
Please refer to section 5.1 - Introduction for general
considerations.
Fire protection
For reaction to fire classifications for Gyproc and Glasroc
boards please refer to Section 2.1 .
DriLyner TL, RF and MF systems incorporate mechanical
fixings, which, when Gyproc thermal laminates are used,
extend the fire protection afforded by the plasterboard to
the insulating material.
Sound insulation
Airtightness is essential for optimum sound insulation.
Whilst most junctions will be sealed by standard jointing
materials, gaps at the base of the wall and other small
airpaths can be sealed using Gyproc Sealant.
Thermal properties
Gyproc linings are relatively lightweight and have a low
thermal capacity. In conditions of intermittent heating,
they will warm up quickly, providing early comfort
conditions for the occupants, and will help reduce the risk
of harmful surface condensation.
5.2
228
Condensation and water vapour resistance
Gyproc WallBoard Duplex offers significant resistance to
water vapour transmission. The application of two coats of
Gyproc Drywall Sealer to Gyproc WallBoard, Moisture
Resistant or Gyproc Thermal after installation and jointing
provides a water vapour resistance of at least 15MNs/g.
Please refer to section 5.1 - Introduction, CONDENSATION
CONTROL.
The use of Gyproc WallBoard Duplex or plasterboards
supplemented with a vapour control layer treatment such
as two coats of Gyproc Drywall Sealer, considerably reduces
the risk of interstitial condensation.
Drying out
It is important, particularly in new buildings, that external
walls are properly dried out before a vapour control layer
is provided. Otherwise moisture may be trapped which will
impair the performance of the construction.

DESIGN
Please refer to section 5.1 - Introduction for general
considerations.
Planning - key factors
In general, an allowance of the total board thickness plus
3mm for DriLyner RF, 10mm for DriLyner BASIC and TL and
20mm for DriLyner MF, should be made from the face of
the background to the face of the plasterboard lining. This
will determine the lining dimension required at door and
window reveals and soffits. If the background is badly out
of line a greater allowance may be necessary.
Ceilings should be installed prior to the application of
DriLyner linings, ensuring that the boards are cut close to
the wall.
Any partitions abutting the inner leaf of the external wall
should also be installed prior to dry lining.
Cavity barriers
Building Regulations may require the provision of vertical
cavity barriers to long runs of lining. A suitable cavity
barrier can be formed using a continuous vertical line of
dabs running down the centre of a board.
Thermal performance
Uncontrolled air movement through the drylining cavity
can result in excessive heat loss from the building. A closed
cavity between the lining and the background 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 of Gyproc Compound 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.
Integrity of construction and integrity of lining are unlikely
to be issues with existing walls, therefore the foregoing
design precautions are unlikely to be required with the
DriLyner RF system.
For further guidance, please refer to section 5.1
- Introduction, Integrity of linings.
Window and door reveals
When using the DriLyner MF system, if Gyproc WallBoard or
Gyproc thermal laminates are being used, the reveals may
be lined with narrow widths of board directly bonded to
the background with Gyproc Compound. Where it is
necessary to continue the DriLyner MF system throughout
the reveal, i.e. when fixing Duplex grade boards, channels
should be fixed as near as possible to both the external
angle and the frame.
Drywall masonry lining systems
T 00353 1 629 8400
If thermal laminates are to be installed and the dimensions
of the frame prevent the same thickness of thermal
laminate being used in the reveal, a thinner laminate or
Gyproc WallBoard can be used, providing the requirements
for insulation around openings is observed.
Backgrounds
DriLyner linings should only be installed to backgrounds
that are dry and protected from the weather.
In DriLyner BASIC, DriLyner TL, and DriLyner MF systems,
linings can be fixed directly to low and medium suction
masonry, as well as pre-cast and in-situ normal ballast
concrete, using Gyproc Compound. Concrete backgrounds
should be pre-treated with ThistleBond-It in accordance
with section 1.6 applied in bands to correspond with the
adhesive dab centres.
In the DriLyner RF system, linings can be fixed directly to
suitably pretreated plastered wall surfaces, or suitable
level, solid backgrounds of brick, block, or fair-faced
concrete, using Gyproc Sealant.
Variations in moisture content of the background will lead
to differences in its suction characteristics. When these are
extreme, either with slow drying conditions, or dry, hot
conditions, care must be taken. If wet, allow the
backgrounds to dry out. In dry, hot conditions, care should
be taken to avoid rapid loss of moisture prior to the set of
the adhesive.
When a considerable quantity of moisture may be present
in the building, due to the condition of the building fabric
or to prolonged damp weather, consideration should be
given to the use of dehumidifiers or appropriate heating
and ventilation to speed the drying-out process.
Installation of the lining before the building is adequately
dry may have an adverse effect on both the building and
the lining itself.

DriLyner
Drywall masonry lining systems

When installing DriLyner linings to composite wall
structures consisting of concrete columns with infills of
brick or block, dabs of adhesive should not be located on
the columns but only on the brick or block infill areas. This
may reduce the likelihood of cracking of the finished lining
as a result of differential movement from the background.
Adhesive Dab location
Dabs should be applied in a regular pattern in accordance
with BS 8212: 1995 and BS 8000: Part 8: 1994 to give a
minimum area of contact between board and background
of 20%. Cavity barriers, where required, can be formed
with continuous dabs.
Services
The cavity between the linings and the background can be
used to incorporate services. This minimises the depth of
chasing required in the background. Pipes and conduits
should be fixed in position before lining work commences.
To maintain an airtight construction the perimeter of any
penetration through the lining should be sealed as
necessary at the time the services are being installed.
Board finishing
Please refer to section 1.5 - Finishing Coat Plasters,
section 2.2 - Jointing and section 2.5 - Decorative
effects.
Estimating
The estimated construction times (ready for finishing) are
as follows :

GYPROC COMPOUND
The insulating backing of the laminates should not be
chased to accommodate services. PVC covered cables must
not come into direct contact with polystyrene insulation.
Suitable isolation methods such as conduit or capping
should be used.
All services should be installed in accordance with all
available standards, guidelines and recommendations.
Fixtures
Lightweight fixtures can be made directly to the lining. For
other fixtures, the fixing device used should be long
enough to give adequate penetration into the solid wall.
Ceramic tiling
Tiles up to 12.5mm thick with a maximum weight of
32kg/m2, can be applied to the lining using thin-bed
adhesives (usually 3mm thick). Please refer to section 2.3
- Ceramic tiling. In wet-use areas Gyproc Moisture
Resistant should be used or two coats of Gyproc Drywall
Sealer should be applied to the surface of the lining to
protect the boards against moisture. Wall linings should be
left to stand for at least 7 days before tiling commences.
Additional fixing provisions will be required during
installation.

Gyproc Compound should be mixed to a thick consistency
using clean water.
The application of Gyproc Compound to frozen
backgrounds must be avoided. The compound is not
suitable for use where the temperature exceeds 43ºC.
