Frequently Asked Questions

• XFrame parts are plywood – a mix of 12mm, 17mm and 21mm depending on the structural requirements.

• Radiata pine is New Zealand and Australia’s most widely grown plantation timber. New Zealand harvests more than 30 million cubic meters annually (with 495 million cubic meters of volume standing at any one time). With more seedlings being planted today than ever before, and a growth time of between 18 and 25 years, the long-term availability of Pinus radiata-based timber products is secure. Refer to this document for further information about the raw material.

• Generally, follow a standard 600mm planning module when drawing out spaces and/or setting wall heights. When turning corners this module can either have no modular offset, or start outside the line of the wall. We also have a Revit family for the XFrame system – as well as many CAD drawings and pre-built models. Please contact us or visit our downloads page to learn more.

• We have three different versions of XFrame that are based around 3 different modular conditions: 420mm, 525mm and 600mm. Each modular system is most efficient when forming panels twice as long as its base module (i.e., 840mm, 1050mm or 1200mm). These select modules are designed to match current industry standard modular efficiencies and/or specific wall framing use cases:

  • XF1200 (90mm and/or 140mm in depth) | Designed for non load-bearing (90mm) and load-bearing (140mm) walls. Our most popular offering based on industry standard modules.

  • XF840 (114mm in depth) | Designed for non-load bearing internal walls/commercial fit-outs/event infrastructure. The 840mm module is designed for diamond lining arrangements which yields highly efficient lining parts from standard sheets while also offering a highly efficient structural module.

  • XF1050 (104mm in depth) | The base module of the XFrame Office System and XFrame's Acoustic offering. The 1050 module is designed around 2100mm high wall panels - optimised to be an ideal wall height for enclosed one-to-two-people meeting spaces.

  Note that each different modular version is not designed to natively work together (although this can be achieved if required).

• The price per m2 will depend on the manufacturing costs locally and the supply cost of the raw plywood products. We have independent quantity surveying estimates that show the system to be priced competitively to other prefabricated and modular construction solutions. Please get in touch if you would like to learn more.

Internal lining material options very flexible. We like to see sustainable, durable and reusable products used such ZeroE (Strawboard), SaveBOARD, Strandboard (made from waste wood products), FSC certified high quality plywood and/or acoustic materials with high recycled contents. Plasterboard (drywall) can be fixed if required, however, this limits deconstruction and recovery potential.

We will prefabricate all sheet lining products to match XFrame wall panels as required (excluding plasterboard). These pre-finished and pre-cut linings are then fixed to the XFrame panels using a supplied hidden reversible pressure clip. The combination of pre-cut linings and reversible fixings makes deconstruction effortless and means linings can be installed quickly with extreme precision.

For the hidden panel fixings we offer two options that are fit for reuse:

• The first is the use of the Fastmount system. This is a great hidden fixing system that is very durable and suitable for many reuse cycles. The Fastmount system is required when XFrame is used in ceilings.

• The second is our own in-house hidden pressure clip. These work with all the holes milled in the XFrame system by default. These clips are not as durable over as many cycles as the Fastmount system, however they are more economical. These clips push into the pre-positioned holes in the locking plates. Using this approach on a standard panel, you can have any lining size in 600mm increments.

XFrames acoustic performance is determined almost entirely by the lining specification. One of the main advantages of XFrame is the easily demountable linings and so we are very conscious of compromising this with additional layers to improve acoustic performance. Demountable linings generally require an exposed joint at regular intervals (such as a shadow gap) to aid in deconstruction. This has a negative impact on acoustic performance. We also strongly advise against the use of plasterboard as it cannot be demounted without creating waste. 

• Our base partition wall specification: 90mm frame, 50mm AAB high density polyester insulation, 12mm timber sheet linings on pressure clips to both sides, achieves an STC of 39.

• We achieve this by placing a 9mm strip of plywood under the vertical joins in lining panels. This configuration achieves moderate acoustic performance without compromising deconstruction. 

• An improved (acoustically) specification can be achieved by adding a 4kg/m2 flexible acoustic barrier behind linings. This raises the STC performance from 39 to 43 (approx. Rw38).

• Higher acoustic transmission control ratings can be achieved by adding additional mass to the wall, typically via secondary linings (additional layers of 12mm material) or via flexible acoustic barriers.

• The system works on 3 scales – parts, panels and walls. Panels can be built from parts and clipped together to make walls. These can be easily and quickly separated back into individual panels as needed, many times. If you want to change the panel's shape, you can pull the individual parts off the panel and rearrange them or introduce new parts to form a panel of a new height or shape. The parts and panels are good for multiple use cycles.

We have modified the mortise and tenon connections to take advantage of the dimensional stability of the longitudinal span direction of plywood – and the variability of the materials thickness. The effectiveness of this approach as been tested and validated in sub-zero (-5 degrees Celsius) (Central Otago, New Zealand) and high humidity (85%) (Auckland, New Zealand) climates. We allow +0.8mm in the thickness of each plywood joint to allow for up to 7% variation in material thickness (thickness variations resulting from moisture related expansion and/or manufacturing variances). In the longitudinal direction plywood is extremely dimensionally stable (moisture related expansion <0.35% - less than 0.042mm for 12mm plywood). Because of this our mortise design’s are set at a 0mm off-set. This results in a firm, reliable connection regardless of the ambient weather conditions.
