Fiber cement (FC) is a highly durable composite material made from Portland cement, ground sand, cellulose fiber, selected additives and water. It contains no asbestos, glass fibers or formaldehyde. Our products enjoy the benefits of cementitious products (they resist fire, moisture, rotting, insects) while providing the workability and ease of installation compare to wood (they can be nailed and saw cut). They are regarded as being friendly to the environment and are extremely low in maintenance.
“Autoclave” is an important process in making FC boards. Essentially, it is a process where “green boards” are fed into curing chamber (like a giant pressure cooker/ steamer). The temperature is kept at 180oC and the pressure is maintained at 8 bars. The entire autoclaving process takes about 16 hours. Upon completion, boards will be fully cured. Under natural condition, cementitious product will take 28 days for full curing.
Installation of wet boards is not recommended because upon drying off, boards will likely shrink and cause unsightly appearance on the finished wall. Wet boards will cause delay in board installation progress as they need to be dried before installation.
External boards must be painted as soon as possible after installation. You can use exterior grade water-based quality acrylic paint. Always refer to paint manufacturer for painting instruction. When applied internally, use interior grade water-based paint. In wet area, it is suitable to apply tile over the PRIMA board.
Wood stain finishes are generally formulated to enhance the grain of natural timber products. These coatings are normally available in solvent-based and should not be applied onto FC products. Use only water-based wood stain coating formulated for FC products.
Brochures, architectural & BQ specification guidelines, CAD files and installation instructions which are available in either website or hardcopy. Upon request, we also provide typical details tailor-made for specific project needs, commonly referred as “Customised Design Solution” (CDS).
We do not provide structural calculation on other complementary items such as the design of mild steel frame or light gauge steel frame that support fibre cement application. We also do not provide services related to Profession Engineer (PE) endorsement. Apart from that we do not provide full time on site supervision for running projects.
A reference book containing rules/ regulations/ requirements related to construction of buildings. Example – Classification of building material (i.e. Class O, Class 1 to Class 4) is covered in Clause 204.
Under the UBBL Malaysia 1984, Clause 204, a material is classified as meeting the “Class ‘O’ – Surface of no flame spread” requirement if when tested to BS 476 Part 6, has an Index of Performance not exceeding 12 and a subindex (i) not exceeding 6.
It provides a comparative measure (expressed as Fire Propagation Index) of the contribution to the growth of fire made by an essentially flat material, composite or assembly. Best possible result is “0”.

This certificate serves as evidence which attached to C1/C2/C3 BOMBA forms and to be submitted when applying for CF (certificate of Fitness for Occupation). Without the certificate, the project will be deemed not having the class 0 materials for the respective application, hence CF will be not be issued.
If required, HCI can also assist to fill up C2 & C3 forms but the relevant information must be provided. Nevertheless, the contractor and architect have to sign/ chop at the relevant section, hence the following info has to be obtained:-
Yes. IKRAM is an annually published reference book containing listing of locally manufactured building materials. Being listed in this publication is a pre-requisite for qualifying of a product to be used in government projects. This exercise is in line with the Ministry of Finance’s directive – “Arahan Perbendaharaan (AP) 169.2” forming part of the content of “Surat Pekeliling Perbendaharaan Bil. 7 Tahun 2002”. One can lodge a report to IKRAM if any of the government project site known to have used imported products without consent from MOF.
No. These screws were not designed for fixing FC boards. The screw head is smooth and not equipped with ‘serration’ (sharp saw-like ribs). Thus, screw heads will not flush properly with the board surface or embedded in the FC board.
You can use PRIMA Jointing Compound Plus that suplied by HCI. The compound has a natural cementitious component which is compatible with fibre cement boards. It is not preferable to use gypsum based compound for flush jointing process.
HCI IBS wall systems have an IBS factor of 1.0. Maximum possible score for wall element is 20 points. Assuming 70% of the total wall area is fabricated using PRIMA IBS System, the IBS score would be calculated as follows –
= IBS factor x Max. possible score x % of wall area using PRIMA IBS
= 1.0 x 20 points x 70% usage —- 14 points
Example of IBS wall systems include – masonry block work (IBS factor = 0.5), pre-cast concrete panel (IBS factor = 1), other drywall solutions such as gypsum board drywall (IBS factor = 1). For more information can contact CIDB IBS Centre.
RISP is an initiative by JKR (Specialised Services Div., Civil, Structural and Bridge Engineering Branch) to register IBS suppliers that involved in manufacturing & supplying structural building components such as beams, columns and floor slabs. It is an additional registration requirement for government jobs
MSDS is an abbreviation of Material Safety Data Sheet. This is a document containing information about the composition of a product, precautionary measure when handling the products, etc. A copy of MSDS for PRIMA products can be produced upon request. May refer to HCI Technical Services Department or R&D Dept.
