Can I use FireCrunch for construction in a BAL FZ Area

Q2: How do you set the joints on FireCrunch?

Setting the joints on FireCrunch is a simple process. It is very similar to standard plasterboard joint setting however there are a few things to note.

Base Coat – Use Pro Plaster base compounds trades 40, 40 minute set.
Specifically formulated extra bonding adhesive for embedding PAPER TAPE to FireCrunch Joints and internal angles.

Tape – Use paper tape internally. External see Fire jointing instructions Fire Manual.
See plaster set page manual for warranty instructions on plaster setting base coats tape and joints.

Top Coat – Use Pro Plaster 4T Multi purpose compound.
Used for everything from internal / external angles, suitable’ finish texturing coats. This light-weight joint compound and feathers out superbly and delivers a virtually pock free smooth finish.

Manufacturers instructions should always be followed. Data sheets can be downloaded from links below.

Applying ProPlaster and 4T Multi-purpose compounds to FireCrunch is a warranty requirement for joint flushing with FCA products.

Preparation

ProPlaster base compound Trades 40 and 4T Multi Purpose compounds should be stored at room temperature for at least 24 hours prior to use. Mix lightly and test apply. Do not over mix as this can cause pocking. Add water 250 ml at a time as necessary; remix and test apply before adding additional water.

Application

Any surface imperfections or damage that may have occurred should be repaired to the board surface prior finishing. Apply over dry surfaces only and allow each coat to dry completely before applying another coat. Maintain minimum air, joint compound and surface temperature of 13c within working area until joints are completely dry.

Class 4/5 Finishes

To obtain a class 4/5 finish mix an amount of 4 x diluted mix of plaster base coat and either roll or spray on the installed sheets. Apply light fine grade sand after 24 hours which will produce a class 5 finish when painted. Alternatively use Dulux prep coat or similar if required.

Hand Tool Application

Embed “plasterers paper tape” to the FireCrunch; make sure no fasteners protrude above the FireCrunch panel surface using a broad steel finishing knife.

Use Pro Plaster Trades 40 aping compound to fill the channel formed by the taped edges of the panels. Centre and lightly press paper tape into fresh joint compound. Working within a convenient arms-reach area embed tape by holding knife at an  angle to panel, draw knife along joint with sufficient pressure to remove excess compound, above and below tape and at edges.

Leave sufficient compound under taper for proper bond, while embedding, apply a thin coat of Pro Plaster Trades 40  compound over the tape. This thin coat reduces edge wrinkling or curling and makes the tape easier to conceal with following coats. Allow to dry completely.

Fill Coat Application

After the Pro Plaster tape embedding coat is dry, apply a topping using Pro Plaster 4T Multi Purpose or simlar approved compound, fill second coat approx 180mm to 250mm wide over taped joint. Feather edge of second coat 50mm beyond edge of first coat. Allow to dry.

Finish Coat Application

After second coat is dry. Apply a thin finish coat of 4T Multi Purpose Compound over joints. Finish compound, should be applied at a slightly thinner consistency. Feather edge of third coat at least 50mm wider than second coat.

Finishing Inside Corners

Apply a thin layer of compound to either side of the corner. Crease centre of tape and press into corner. Tightly embed tape with knife on both sides removing excess compound and apply it as a thin coat over tape. Apply second coat over one side at a time allowing it to dry before finishing opposite side.

Sanding Application

Light sand with a wet sponge to eliminate dust and scuffing . Remove high spots using as few strokes as necessary. Clean sponge often. If dry sanding, use 180 grit sandpaper or finer. Avoid scuffing tape.

If dust is generated wear suitable protective clothing including PVC gloves (AS 2161), Eye protection (dust resistant AS/NZS 1336), and a respirator (AS/NZS 1715 and 1716.Wash clothes regularly.

On completion of all plaster set and ready undercoats USE ONLY a  vapour permeable sealer on FireCrunch MgSO4 sheets.

Q3: Can I put wall and floor tiles on FireCrunch?

Yes. FireCrunch is not that dissimilar to fibre cement board when it comes to uses.

FireCrunch has been trialled with budget tile adhesives and worked perfectly.

Q4: Do I need any special tools for FireCrunch?

No special tools are required to use FireCrunch.

It can be sawn, drilled, screwed and planed just like timber. USING TIMBER TOOLS.

It is recommended that screw fasteners, not stud adhesives, are used when fixing the sheets in the wet areas of steel and timber framed buildings.

FireCrunch is easy to work and machine with normal woodworking tools and equipment. Cut sheets with a fine tooth handsaw or power saw. Edges may be trimmed with a smoothing plane,
power plane or sandpaper.

Panels with thicknesses 10mm and under can be deep scored with a cutting knife and snapped along the straight edge in the same way as you would with gypsum boards.
Where holes are required clean cutter bits or twist drills are satisfactory.

Woodworking shapers, spindle moulders and high speed routers may be used to shape or mould the edges of FireCrunch. Tungsten carbide tipped cutters are preferred for long production runs.

Note: FireCrunch does not require the use of expensive countersinking to fix which takes extra time time and requires expensive tungston tipped drills and saws. As with CFC cement sheeting and is some 35% less in price

Q5: Does FireCrunch have Australian Building Code certification?

Yes.

FireCrunch is NATA Labs CSIRO Fire Certified to Australian standards and also complies with the following sections and volumes of the BCA (Building Code of Australia), ABCB Canberra and NCC National Construction Code.

Q7: How does FireCrunch compare to other building panels?

How does FireCrunch compare to other building panels?

Q8: How does FireCrunch perform in tropical, high humidity areas?

Priming sealing before painting or rendering.

FireCrunch must always be sealed and finished regardless of where or how it is used, however this is particularly important in areas of high humidity. Extra care must be taken to ensure the board is sealed correctly on the face, top and exposed edges, leave the inner back rough side of board unsealed.

All FireCrunch MgSO4 composite fire boards must be pre-sealed with Klaas S1 AquaCrunch (vapour Permeable” prime sealer. Failure to use this product before painting or rendering will void the warranty. Available direct wholesale from FireCrunch (Ask us)

FireCrunch will not attract mould or Mildew and bacteria cannot survive on (MgSO4) FireCrunch

Correct preparation and sealing will ensure a long life for your building.

Q9: How is FireCrunch different to plasterboard?

FireCrunch differs from plasterboard in a number of ways in that it is:

  • Approx. ten times stronger
  • It won’t degrade in water*
  • It cannot be eaten by termites so totally protects timber framing
  • Is easier to handle and use (less chance of board damage)
  • Can be used as both an indoor and outdoor lining
  • Improves the thermal and sound insulation of your project
  • Acoustics are Rw 62 plus ctr =net Rw52
  • BCA requirement Rw 50 net
  • 90mm frame cavity using appropriate ( Mfg) insulation batts FRL 90/90/90
  • Is virtually fire proof (CSIRO certified). See Certifications (FRL 30/30/30 to 90/90/90)

* Prolonged submersion in water without an opportunity to dry out will void the FireCrunch warranty. Before using, treat this product as an indoor product:  store out of water, under cover, prior to sealing with warranty (“Vapour Permeable Sealer”) Klaas S1 AquaCrunch,

Do not use regular undercoating otherwise paint surfaces may be affected, use standard water based paints when pre sealed.

Q10: How should FireCrunch be stored and handled?

Although FireCrunch does not degrade in water it should not be left out in the rain as there will be a low % of HYDRATION IE, absorption of water. If this does happen the board will have to be dried out before use… drying out the board will not cause warping or any loss of integrity.

FireCrunch should always be stored flat in a dry undercover space on a horizontal pallet or on supports spaced at 450mm centres. It should not be stored laid directly on the ground.
AND DO NOT LEAVE THE BOARD HANGING OVER THE PALLET EDGES OR GLUTS OVER 450MM IT MUST BE SUPPORTED FLAT as all time prior to use.

Always handle with at least one person at each end of the board. With hands apart, lift the board and tilt to prevent sagging. (See data sheet for more information).

Q11: Is FireCrunch comparable in price to plasterboard?

FireCrunch is more expensive than plasterboard due to the additional properties that make FireCrunch a superior lining product.

We cannot give you price variations here as plasterboard prices vary between suppliers, however, the cost of maintaining plasterboard in the long term well outweighs the cost of installing FireCrunch to begin with. Plus only 1 layer of 10mm FCA equals 3 layers of 13mm for 90 minutes in fire.

FireCrunch is substantially lower install cost in materials and labour.

FireCrunch substantially lowers overall labour cost and transport (weight) and crane up and site handling time all of which speeds the completion and lowers install cost in materials and labour. it also increases the ROI to developer with thinner walls and more lettable space.

Q12: Is FireCrunch environmentally friendly?

Yes.

FireCrunch is recyclable, contains no toxic chemicals, FORMALDEHYDE, ASBESTOS OR VOC (Ask us for copy SDS or see Certifications, Australian Govt legal requirement) technical@FireCrunch.com.au or call 1300 933 102.

FireCrunch has one tenth the carbon footprint of fibre cement plaster board and due to the need for less repair, has less wastage. During the manufacturing process, in carbonation, FireCrunch draws back 90% of the CO2 used in manufacturing and makes it a virtually carbon neutral product. Any waste is just ground up and reused.

Only 1% wood chip used in FireCrunch products, eliminating the destruction of millions of oxygen generating, C02 absorbing green trees in the manufacture of paper lined plasterboard. Choose FireCrunch, an environmentally responsible cladding product.

Q13: Is FireCrunch fire proof?

FireCrunch has a very high fire resistance and has been tested at temperatures up to 1200ºC for over four (4) hours and board did not ignite or pass flames) CSIRO.

FireCrunch exceeds BCA minimum requirements for airborne sound insulation between walls AS 717. » See Certifications.

Q15: Is FireCrunch termite proof?

Yes.

Termites, one of the worst contributors to home damage, have no interest in FireCrunch, they cannot consume it and are repelled by (MgSO4) TOTAL PROTECTION FOR EXPENSIVE TIMBER FRAMING

Q16: Is FireCrunch toxic in any way?

No.

FireCrunch contains no formaldehyde, no asbestos and no toxic chemicals. OR CORROSIVE MAGNESIUM CHLORIDE Fire crunch uses Magnesium Sulphate (MgSO4) being a non-corrosive element and in this regard is unique at present in Australia ( NO VOC)

Q17: Is FireCrunch water proof?

Standard FireCrunch is a water resistant product before sealed in that it does not retain water if unsealed.

This means that an “unsealed board will absorb some moisture in damp or wet areas” if left unsealed. You should not expect the board to hold it’s integrity if submerged in water or exposed to multiple wet/dry processes, before use particularly without adequate MgO sealing.

Use special Mgso4 “vapour permeable Sealer” (» See recommended recommended products). Klaas AquaCrunch S1.
FireCrunch should not be left out in the rain before sealing /priming. Mgso4 Sealer (» See recommended recommended products)

Because it is a breathing permeable board it will hydrate when not sealed.

However, if inadvertently left in the wet or in exterior weather, move to a dry environment with separated sheets. FireCrunch will dry out quickly without swelling or warping and hold it’s strength integrity.

FireCrunch that has been installed externally and not pre sealed could crack at fixtures due to residual moisture in the board being removed in the drying process, especially when exposed to multiple wet/dry processes.

Best practice: Store undercover on delivery to site before use. Do not attempt to paint if board wet.

Allow to dry completely before sealing painting or rendering, hydroscopic level under 10%.

Is there information available on the strength of FireCrunch for flooring?

Q19: Should I use nails or screws to fix FireCrunch?

FireCrunch must not be nailed, using hand hammered nails, this will void the warranty. Power driven nail hammers can be used however, always extra screw fix the 4 corners and board centres, and as well use corrosive proof galvanised nails only.

Take note of the recommended screws that must be used. (» See technical manuals)

FireCrunch Australasia warrant the board only when the correct screws and system manuals are adhered to. (» See recommended products).

Screw Fixing

Steel frame: For screwing FireCrunch panels to steel framing, we recommend using Ribbed head bugle self countersinking screws available from all major hardware stores.

Timber frame: For screwing FireCrunch panels to wood framing we recommend using stainless steel (or suitably corrosion protected) 8-10 Countersinking Ribbed Head Class 2 / 3 screws (depending on timber hardness).

Q20: What are the acoustic properties of FireCrunch?

FireCrunch exceeds BCA minimum requirements for airborne sound insulation for a wall between attached dwellings or intertenancy walls and meets the highest possible AAAC acoustic rating of 5 stars.

Q21: What is FireCrunch made from?

FireCrunch is made up of a combination of primarily Magnesium Oxide (MgO) and special non-metal corrosive magnesium sulphate Magnesium Sulphate (MgSO4)

NEW TECHNOLOGY 2018

FireCrunch is made up of a combination of primarily Magnesium Oxide (MgO) and Magnesium Sulphate (MgSO4) This has been bonded with a small percentage of organic and IP composite materials, strengthened with fibre mesh.

MgSO4 is a new development in the FCA range and replaces Mag chloride ( MgChl2) with Mag sulphate and eliminates all metal corrosion, a common problem with ordinary MgO chloride boards (MgChl2)

What is Magnesium Oxide?
MgO or Magnesium oxide (sometimes called magnesia), is an absorptive solid mineral, white in colour, that occurs naturally in metamorphic rocks and is sourced from magnesium mining. Magnesium oxide is a waste by product of external use process in steel manufacturing .

ENVIRONMENTAL — FCA is 100% better

FireCrunch is produced by the addition of magnesium sulphate to the mag oxide and lime followed by a heat process
using low Co2 kiln temperatures ,50% LESS than plaster board products, so 50% less Co2 .

During the carbonation process of manufacturing, FireCrunch draws back 90% of the 50% Co2 created to produce FCA
and makes it a virtually carbon neutral product.!!

Further, FCA eliminates the “additional destruction “of millions of oxygen producing trees each year to manufacture
weak ineffective low R value insulation, paper lined plaster board and protecting them from termites, floods and fire !!

Q22: What is the Fire Resistance Level (FRL) of FireCrunch?

FireCrunch has:

  • Load bearing (steel frame FRL of 90/90/90 55Kn/ NATA LABS CSIRO NSW
  • Load bearing (timber frame FRL of 60/60/60   NATA LABS RESOLUTE QLD
  • Non Load bearing FRL of —/120/120 more on application of additional 10mm sheet per side

*** ( DENOTES– Read timber framing specs for FRL 30/30/30 ( Bush fire manual ) and FRL 60/60/60 (Main Fire Manual) before commencing work on any firewalls. (» See technical manuals)

The Building Code of Australia (BCA) defines the Fire Resistance Level (FRL as the testing period in minutes for three criteria:

  • IE 60/60/60 first figure is Structural Adequacy (the ability of a structure to maintain its stability and
    load bearing capacity)
  • 2nd figure is Integrity (the ability of a structure to resist the passage of flames and hot gases)
  • 3rd figure is insulation (the ability of a structure to maintain a temperature below specified limits on the unexposed surface being 180 Deg c plus ambient as a maximum allowed at any one point of the unexposed side of the fire wall).

The longest test time recognised by the BCA is 240 minute period 4 hours.

Q23: What is the R-Value for FireCrunch?

The R-value of FireCrunch is a measure of its thermal resistance. The higher the numbers the better the insulator.

R-value is measured as m2/K/w

The values for FireCrunch are:
10mm FireCrunch = 0.066 m2K/w
19mm FireCrunch = 0.132 m2K/w

So the 10mm board has an R Value of 0.066

For example:
To work out the approximate R-value for a wall with a layer of 10mm FireCrunch each side of the stud with a R2.5 batt between them –

10mm FireCrunch + Batt + 10mm FireCrunch = Wall R-value therefore 0.066 + 2.5 + 0.066 = 2.632 (So the approximate R-value for the wall would be 2.6)

Please note that the above is just an approximate guide. Actual figures would have to be calculated. There are a number of on line calculators that can do this for you.

Q24: What should I do if FireCrunch gets wet before installation?

You should do all you can to prevent FireCrunch getting wet before installation as there will be some water absorption. If this happens, don’t worry, it just means you will need to separate the hydrated boards from each other and allow to dry in a sheltered warm space, preferably with low humidity. The boards will not be damaged or degrade if handled correctly. Once dry, install and immediately before or after installation seal the exposed face of the board with the recommended “MgSO4 primer sealer – see recommended products. Once sealed you can use most normal water based paints and renders.

Q25: What sizes and thicknesses does FireCrunch come in?

The FireCrunch standard range of sizes is as follows:

Q26: What thickness FireCrunch should I use for flooring?

FireCrunch 16mm TG is for exterior decking groove board. 19mm TG is ideal for flooring and for roof fire protection in bushfire areas to BAL FZ, over trusses before steel or tiled roofing installed.

Q27: What type of board edges does FireCrunch offer?

FireCrunch is produced in FIVE different thicknesses and 4 edge types 10mm; 12mm ,16mm and 19mm TG which cover most 80/90% of all fire requirements.

There are also a few different types of edges for different types of application. Sheets suit floors, walls interior and exterior, ceilings roofing and decks.

To simplify this, please view the charts on the specific product(s).

Q28: What types of paint can be used on FireCrunch?


Important information before painting or rendering FireCrunch MgSO4 cladding.

Most standard water based paints can be used on FireCrunch, however it is essential to use a Vapour Permeable prime sealer before applying any top coats.

This with many other tested or recommended support use products for the installations are found at www.firecrunch.com.au/recommended-products.

The recommended Vapour Permeable primer sealer must be used before applying any paint or render to the FireCrunch Boards. The FireCrunch warranty requires the use of this type of sealer, as otherwise later paint surface issues may occur. Do not use standard water based undercoats or primers (warranty)!
