Gyproc Activ’Air® WallBoard
INTRODUCTION
Overview
Gyproc Activ’Air® WallBoard is a paper faced
plasterboard offering the unique performance
characteristics of Activ’Air® technology, capturing and
neutralising formaldehyde, the most common airborne
volatile organic compound (VOC).
Characteristics
Gyproc Activ’Air® WallBoard consists of an aerated gypsum core with
Activ’Air® ingredients and is firmly bonded to strong paper liners front
and back.
Board Colour
Ivory – Face Grey – Reverse
Applications
Gyproc Activ’Air® WallBoard is universally suitable for most internal
dry-lining applications where standard fire, structural and acoustic
levels are specified. It is a lightweight gypsum plasterboard that
handles like other Gyproc gypsum plasterboards, is suitable for direct
decoration or Gyproc plaster finish, does not require special tools and
is easy to cut and install.

Activ’Air® technology
Activ’Air® can be used in our daily environments to improve the
indoor air quality and provide healthier environments where we live,
learn and work. Activ’Air® technology captures up to 70% of
formaldehyde present in the adjacent environment and converts
them into safe, inert compounds that, once captured in the board,
cannot be released back in to the air. Based on tests and analysis, the
Activ’Air® process can keep working for up to 50 years, even after
multiple renovations.

BOARD PERFORMANCE (continued)
Fire protection
Effect of temperature
Reaction to fire class
Effect of condensation
Plasterboard linings provide good fire protection owing to the unique
behaviour of the non-combustible gypsum core when subjected to
high temperatures. Gyproc Activ’Air® WallBoard satisfies the
requirements for Class 0 surfaces in the national Building Regulations
when tested to the relevant EN standard (see below).
A2-s1,d0 in accordance with BS EN 13051-7:2002 Fire classification of
construction products and building elements.
Fire resistance
Fire resistance performances can be achieved when Gyproc Activ’Air®
WallBoard is used as part of a Gyproc system e.g. GypWall metal stud
partitions.
Gyproc Activ’Air® WallBoard is unsuitable for use in areas subject to
continuously damp or humid conditions and must not be used to
isolate dampness. Plasterboards are not suitable for use in
temperatures above 49ºC, but can be subject to freezing conditions
without risk of damage.
The thermal insulation and ventilation requirements of national
Building Regulations aim to reduce the risk of condensation and mould
growth in buildings. However, designers should take care to eliminate
all possibility of problems caused by condensation, particularly in
refurbishment projects.

INSTALLATION
General
It is important to observe appropriate health and safety legislation
when working on site, i.e. personal protective clothing and equipment
etc. The following notes are intended as general guidance only. In
practice, consideration must be given to design criteria requiring
specific project solutions.
Gyproc Activ’Air® WallBoard should be stored on a firm, flat and level
surface. If the boards are temporarily stored outside they should be kept
clear of the ground and securely covered with an anchored polythene
sheet or tarpaulin to protect from dampness and inclement weather.
Handling
Manual handling of this product should be done with due regard to the
legal requirements of all applicable National Safety, Health and Welfare
regulations.
Cutting
This product may be cut using a plasterboard saw or by scoring with a
sharp knife and snapping over a straight edge. Holes for switch or
socket boxes should be cut out before the boards are fixed, using a
utility saw or sharp knife. When cutting boards, power and hand tools
should be used with care and in accordance with the manufacturers’
recommendations. Power tools should only be used by people who
have been instructed and trained to use them safely. Appropriate
personal protective equipment should be used. Consider monitoring of
exposure levels during this activity.

Fixing
Gyproc Activ’Air® WallBoard should be fixed with the decorative (Ivory)
side out to receive joint treatment, skim plaster finish and/or
decoration, to appropriate supporting members using Gyproc Drywall
Screws of appropriate length and located at appropriate centres
according to the nature of the system and materials to which they are
being fixed. Refer to Gyproc System Solutions Literature for further
guidance. Install fixings not closer than 13mm from cut edges and
10mm from bound edges.
Adjacent boards should be lightly butted together. Never force boards
into position. Position cut edges to internal angles whenever possible,
removing paper burrs with fine sandpaper. Locate boards to the centre
line of framing where framing supports board edges and ends. On
multiple layer installations, stagger vertical and horizontal joints
between layers by a recommended 600mm.

FINISHING
Plastering
The face (Ivory) of Gyproc Activ’Air® WallBoard can be plastered with
Gyproc Skimcoat, Gyproc Carlite Finish or Gyproc Carlite Ultra Finish.
There should be the minimum of delay between completion of the
lining and the commencement of plastering.
Jointing
Gyproc Activ’Air® plasterboards should be taped and jointed prior to
direct decoration or application of a Gyproc plaster finish. Gyproc
jointing filler and finisher materials applied in accordance with our
current recommendations produce durable joint reinforcement and a
smooth, continuous, crack resistant surface ready for priming and final
decoration. Use Gyproc Joint Filler, Gyproc Premium Fill or Gyproc
Easi-Fill prior to plaster finish or finishing for direct decoration.
For flat and internal corner board joints the Gyproc jointing material is
trowel applied to the joint and Gyproc Paper Joint tape bedded into the
joint filler.
For external angles, Gyproc Corner Tape may be used as an alternative
to Gyproc Joint Paper Tape, also bedded into the Gyproc jointing
material. A second coat of Gyproc joint filler material may be required
to ensure a seamless appearance – the joint treatment is allowed to dry
and can then be lightly sanded to remove any unsightly high spots.
Decoration
After the joint treatment has dried, suitable preparatory work may
be undertaken prior to direct decoration or plaster finishing.
Repair
Minor damage – lightly sand the surface to remove burrs and fill
flush with Gyproc Easi-Fill or Gyproc ProMix. A second coat may be
required prior to direct decoration to ensure a seamless appearance
is achieved to the surface of the boards.
Deep indents resulting from impact – check the plasterboard core
to ensure that it is not shattered. If intact, apply a coat of Gyproc
Joint Filler or Gyproc Premium Fill, followed by the procedure for
repairing minor damage as outlined above, once set/dry.
Extensive damage – where the damage to boards is more
extensive, full replacement may be necessary. If only a small area of
the board is damaged, only the affected area needs to be removed
providing the board is cut back to the nearest framing members
and screw fixed along the cut edges. Replace the board by
accurately cutting and screw fixing a new section of the board.
Joint the boards in accordance with the appropriate jointing
method suitable for the finish required.
Where the surface of Gyproc Activ’Air® WallBoard is to be directly
decorated, application of a suitable Gyproc joint finishing material
(Gyproc ProMix or Gyproc Easi-Fill) may be necessary to achieve the
desired, smooth, seamless appearance.
