General

Do you have samples you could send us?


Yes absolutely, please get in touch with us on sales@pacbld.com for what products you would like to get samples of.




Are there examples of projects using your materials that I could view locally?


Yes, please refer to our project page to see some excellent examples. You can also contact us on sales@pacbld.com to find out any specific ones in your area.




Can you send us brochures?


Yes absolutely, please get in touch with us on sales@pacbld.com for what product you would like to brochures of. You can also download each brochure on the product pages on this website.




Can you offer on-site technical support? Does this come at a cost?


Yes we can. Please get in touch with us and we can ensure you get the orientation required. It may come at a cost, this is based on a case by case basis due to projects proximity, size of the job, and timing required





XpressClad

Can you powdercoat the XpressClad rails?


Yes you can, but the rails come anodised black or silver so there is extra cost involved in changing this to Powdercoating. You have to take into consideration that we can not apply our adhesive on to powder coating. It is recommended to anodise the rails the desired colour to avoid the adhesive issue.




What centres are the rails installed?


The rails are typically installed at anything from 400mm, 450mm, 600mm crs. Our max distance is 600mm crs, please refer to our manuals to match your rail layout with your site specific wind zone.




What is the typical layout I should set-out to?


You have to take into account 4 main things:

1. 10mm negative

2. The architects plans and intentions

3. We do not notch our panels around windows or penetrations.

4. For full panels we recommend you trim the width to 1190mm wide so you can keep to stud centres and add your 10mm negative.

Once you have these sorted your layout should fall into place.




Do I need studs & nogs behind the XpressClad rails?


Yes, or solid blocking as your screw centres are at maximum 250mm centres.




Can I join XVR rails?


Yes, but please leave a 3mm expansion gap.

You can run the XPF pocket filler past the joint and butt these tight to each other.




Can I join XZR rails?


Yes, these can be joint but please leave a 3mm expansion gap.




Why are expansion gaps necessary?


Aluminium expand and contract 1mm for every 1m of length, so we typically leave 3mm for the full length rails.




Does XpressClad have LRV restrictions?


No, XpressClad is adhesive fixed so we do not have any LRV restrictions.




Can I use flexible wall underlays with PacBld XpressClad systems?


Yes, flexible wall underlay is acceptable, but this must be approved by Pacbld if you require a full system warranty at the end of the project.





Ramco Hilux

Is Ramco & Hilux the same product? If so, why is it known by these two names?


The true brand name is Ramco Hilux. Ramco is a parent group company and Hilux is the division of the company that produces the board range. So the 2 names always go together.




What is Ramco Hilux made of?


Ramco Hilux is a Calcium Silicate board.




Can I use Hilux externally?


Yes, Hilux is suitable for external use. It does require a paint system / coating to seal it to achieve its intended durability externally.




Do the edges need to be sealed?


Yes when used externally or in wet areas we recommend sealing the edges.




What is its fire rating?


In a soffit application it can achieve up to a 60/60/60 (please refer to the manual)

In a heat shield application it is incombustible, but you need to refer to our heat shield manual to see how this was achieved and what clearances must be maintained.




What thickness is Ramco Hilux? What size is it?


Ramco Hilux comes in a 2440 x 1220mm sheet

3 thicknesses – 9mm, 12mm, and 16mm.




Can you use Hilux in a kitchen or in a wet area?


Yes, it is acceptable in a wet area or kitchen, but will need to be sealed or appropriate heat tolerant membrane used.




Can it be tiled over?


Yes, but please ensure you prepare the surface for the heat tolerant tile adhesive or membrane to adhere correctly to it.





Swisspearl

Is Swisspearl stocked?


No, Swisspearl is a indent only product. It typically has a 16 -20 week lead time.




What size is Swisspearl?


Swisspearl is 8mm thick and comes in 2 lengths – 2510mm and 3050mm and 1250mm wide.

12mm thick is also available for special applications.




Do I need to use your Swisspearl blade to cut Swisspearl?


We highly recommend the Swisspearl blade for a better result, but it is not necessary. You do require a fibre cement finishing blade of high quality that is tungsten carbide or toothless diamond finished.




What do I seal Swisspearl with?


Swisspearl comes with LUKO sealer in the pallets. You run this along any cut edge to seal it. Do not get this on the front face, wipe it off immediately.




Does the LUKO sealant come with the Swisspearl?


Yes, you will find it on the bottom left hand side of the Swisspearl pallet. If you run out of LUKO please get in touch to reorder.




Can I paint over Swisspearl?


We do not recommend painting over Swisspearl. The board is a prefinished sealed product. It will be likely the paint will not stick to the surface, and any modifications to the board will void your warranty.





Shera Board

Do you supply 4.5 – 6mm sheets?


We supply 6mm and up. We have discontinued the 4.5mm.

Can I substitute components when using your system?


No. We do not allow substitution of our components. Our systems such as XpressClad are outside NZBC Acceptable solutions so therefore you are required to use our components to comply with our testing and for us to be able to offer a system warranty these must be purchased as a complete system.

Do you have a sealed version of RWU or Base board?


No we do not carry a sealed version supplied from the warehouse anymore.

For RWU:

We have moved to using a peel and stick membrane over our RWU to create a better longevity and security in significant seismic events.

For Tile or Stone substrate:

In these applications we recommend the board is tanked on site before the application of the tile or stone. The membrane will be what’s compatible with the tile or stone being applied.

Do the edges need to be sealed?


No, you are covering the RWU with a PSM and tapes around all openings.




Why is the PSM required?


The Shera RWU is not sealed, and when combined with the PSM it provides a E2/AS1 solution for behind any claddings. In the event of an earthquake the PSM will also provide more durability from cracking of the RWU and keep your building weathertight for longer.




Do we have to use your PSM?


Yes, we have done all our testing with our specific PSM. We cannot guarantee you compliance or performance with any other.




Do you have to use your fire sealant?


Yes absolutely, all fire rated walls have to use the exact specification we have tested with.




How should I handle penetrations that are needed?


Proclima Roflex for pipes. Kaflex for Cables. Naideck for fixings.

For Fire-rated walls, we do not support any penetrations through our fire-rated walls, refer to you fire engineer.
