PRIMA Premium DrywallSystems & Partitions
Why specifically PRIMA Premium Drywall?
Drywall construction is applied in a dry condition without the use of mortar. The materials used in PRIMA premium drywall construction are Boral gypsum boards, PRIMA fibre cement boards and Rondo Zincalume steel stud. The large Boral and PRIMA board size sheets are fastened directly to Rondo steel stud frames with self drilling screws.
The lightweightness of the materials together combined with the ease and simplicity of construction makes it the preferred wall construction method option. In places where supply is a problem or in construction sites where water is barely accessible, drywall construction method becomes the absolute preferred choice.
Boral, PRIMA and Rondo collaborate to set a quality benchmark for the construction of drywall systems where the user and specifiers can be sure of premium products and performance for:
• Water resistant• Fire resistant• Impact resistant• Soundproof
All three companies are established leaders for their respective building materials used as the main components for drywall constructions to achieve optimum system performance. Boral and Rondo are related companies synonymous with their market leadership in gypsum board system solution while PRIMA fibre cement boards known for its superior water and impact resistant properties are supplied to over 60 countries worldwide.
All three companies therefore serve to complement and enhance the delivery of drywall construction products and solution to builders in Malaysia and worldwide. Therefore it makes sense to insist on PRIMA Premium Drywall Systems for your drywall construction requirements.

PRIMA Premium Drywall is tested to the levels of fire resistance required by building codes and standards.
Impact on walls come in three basic forms; soft body, abrasive and hard body. Each of these can affect the wall lining in different ways and consequently affect the choice of lining system. When PRIMA Premium Drywall are properly sealed and used in a certified sound rated assembly, these products will contribute to required sound transmission classification (STC) values.
PRIMA Premium Drywall offer the following key advantages:
• Strong and durable • Lightweight• Easy installation • Cost effective• Aesthetically pleasing • Superior water & impact resistance
PRIMA Premium Drywall System Overview(PRIMA + BORAL + RONDO)

Fire Resistant All components that make up these drywall systems possess superior fire rating properties. The steel framing system is naturally non-combustible. The lining materials (fibre cement board & plasterboard) have been tested by SIRIM and classified as Class ‘O’ building material under the Malaysia Uniform Building By-law 1984.
The components/systems have been tested in SIRIM Berhad and PSB Singapore in accordance with BS 476: Fire tests on building material and structure. The test results are as follows:-
• Fire Propagation – Index of Performance, I < 12 (BS 476: Part 6)• Surface Spread of Flame – Class 1 (BS 476: Part 7)• Non-load bearing drywall system – One and Two hours rating (BS 476: Part 22)
Water Resistant The facing board in the PRIMA Premium Drywall Systems is PRIMAliner 9mm fibre cement board which has superior wet resistant properties. PRIMAliner is made from a recipe mix of cement, sand and pulp. PRIMAliner has been tested by various certification bodies and authorities for its water resistant properties.
PRIMAliner superior water resistant property has been proven after passing the several test listed below:- • Test to AS 3991.5 : Resistance to Hot Water Soaking• Test to AS 3991.6 : Resistance to Heat and Rain• Test to AS 3991.7 : Resistance to Freeze and Thaw
Upon completion of the test, PRIMAliner remains intact and there were no signs of delamination or structural alteration observed on the test specimens.
Applications & AdvantagesPRIMA Premium Drywall Fire Rated wall systems shown in this manual are suitable to be applied as internal non-load bearing wall/partition for residential or commercial buildings.
The use of the fire rated wall systems described in this manual shall be governed by the Malaysia Uniform Building By-law, Fire Rescue Department (Bomba) and the local authority regulation.
Impact Resistant PRIMA fibre cement board’s ability to withstand impact is undoubted since it is a cement-sand based product with concrete-like strength. When used as a facing board of PRIMA Premium Drywall Systems, it is just the perfect durable and strong board for drywall construction to withstand hard knocks in areas of high traffic and rough handling.
PRIMA Premium Drywall Systems have the advantage of being more solid and resistant to impact loads compared with traditional drywall systems. Impact loads come in three basic forms: soft body, abrasive as well as hard body. The drywall systems covered in this manual give you ‘peace of mind’ knowing that you have already chosen or specified the systems that work.
Designing wall systems to achieve the required Sound Transmission Class (STC) value has been facilitated with the introduction of PRIMA Premium Drywall Systems. The acoustic properties of these systems have been tested in SIRIM Berhad Malaysia and PSB Singapore. The systems’ STC rating ranges from 45dB to 60dB.

Fastening RequirementThe following fasteners are recommended to be used to construct the fire rated systems. Alternative fasteners with equivalent size and suitable head type can also be used, but may require additional work such as sheet pre-drilling prior to installation.
PRIMAliner to Steel Frame
Self-drilling, Self-embeddingHead Screws
Plasterboard to Steel Frame
Bugle HeadPlasterboard Screws
Steel Frame Assembly
Wafer Head Screws
Sheet InstallationGypsum Board Underlay - Apply sheet horizontally, ensuring vertical sheet joint on one side of the stud does not coincide with the vertical sheet joint on the other side.
PRIMAliner Lining - Apply sheet vertically, ensuring sheet joints on one side of the wall do not coincide with the sheet joints on the other side.
PRIMAliner vertical sheet joints must not coincide to that of gypsum board. When applied in wet areas such as for washroom, ensure the wall system will not be subjected to still water.
Please refer to HCI’s comprehensive installation instruction.
To secure steel frame to masonry wall/slab, use 3mm diameter x 50mm long concrete nails or M8 anchor bolts spaced at 600mm maximum centres.

Joint SystemsPRIMAliner sheet joints can be treated as described in the diagram, incorporating perforated paper jointing tape and plasterboard joint compound. Use only joint compound produced or supplied by reputable manufacturer.
Best result can be achieved when both PRIMAliner edges have recesses. Jointing non-recessed edges should be avoided. If it becomes necessary to flush set over non- recessed edges, the bedding layer, topping layer and finishing layer should be broadened to 200mm, 400mm and 600mm respectively.
The combination of recessed edge and square edge is not suitable to be flush set.
Flush Joint (Rebated Edge)
FinishesPRIMAliner can be decorated with 2 coats of 100% quality water-based acrylic paint. For general-purpose applications, there is no requirement for primers or sealers.
Alternatively, the sheet surface can be decorated with wall covering materials, such as wall paper. In all cases, coating, coating manufacturer’s recommendations must be strictly adhered to. For wet area application, tile finishing may be preferable.
Expansion JointVertical expansion joints must be provided to accommodate anticipated movement within a building. PRIMA Premium Drywall Systems require expansion joints to be located vertically as follow:
Horizontal expansion joints must be provided at 3.6mm mazimum centres. Seal joint with flexible fire rated sealant that is compatible with cementitious products.
