Fire Rated Construction Details

Note: Prior to any firewalls being constructed it is essential that the builder consults with the project certifier to ensure that the certifier is aware of the firewall construction procedures and the certifier deems the installer competent.

Fire Resistance Level (FRL) is assessed by three performance measures:-

Structural Adequacy / Integrity /Insulation eg 90/90/90

FRL – 90 Mins. & External Fire Source

CSIRO Full-Scale Fire Test FS 3685/2695 has proven that the QT EcoSeries Wall System (shown right) is capable of achieving a fire resistance of 113 minutes Integrity and 115 minutes Insulation when tested in accordance with AS1530.4. Therefore for the purpose of Building Regulations in Australia, the QT EcoSeries Wall System achieved a fire resistance level (FRL) of 90/90/90. The FRL is applicable for exposure to fire source from the tested side (QT EcoSeries Wall Panel side).

Fire Test – FS3685-2695————– Specimen – Typical Cross Section Fire Rated Vertical Control Joint———— Fire Rated Horizontal Control Joint————

FRL – 90 Minutes

To achieve a 90 minute Fire Rating the wall must be constructed so as the wall consists of two layers of 13mm thick fire resistance plasterboard affixed to the timber frame internally and one layer of fire resistant building foil, one layer of 50mm QT EcoSeries Wall Panel with a 5-8mm render applied with finish, affixed directly to a 20-50mm battened out cavity. This system would be capable of achieving Fire Resistance Levels of -/90/90 for Non Load Bearing walls and 90/90/90 for Load Bearing Walls designed in accordance with AS1684 for fire exposure from either direction if tested in accordance with AS1530.4

90 Minute Fire Rated Wall

Extended Wall Areas

The Fire Resistance Levels of 60 & 90 minutes would still apply to the same system extended in height in modular form provided that the structural members are designed in accordance with the relevant structural design code for the height and load of actual installation and an approved joint system appropriate to the FRL and the width of the gap is used for the horizontal and vertical joints in a manner as detailed in the attached drawings.

QT Finishing

Service

Ensure service pipes and wires are fixed or checked into the frame and not laid loose in the extended wall cavity. All materials that are susceptible to deterioration due to plasticiser migration must be protected (check with product manufacturer). Some PVC products or electrical cabling that penetrate the coating system and QT EcoSeries Wall Panel, require a conduit to ensure it is protected. Copper pipes require a sleeve, conduit or tape to prevent contact with the wall panel.

Penetrations

Voids or gaps created by service penetrations through the exterior wall require weatherproofing and or waterproofing. A common method is to inject with expandable polyurethane foam and seal with a long lasting exterior gap sealant to make a weather tight seal. Where practical add a flange or decorative feature over the hole or penetration.

Sealants

Use an exterior grade weatherproof sealant for exterior wall construction and as a general-purpose gap filling. Apply sealant in accordance to manufacturers recommendations. For a sealant to work effectively, the sealant must be applied as shown in the sketch below, Opening Width (D) x Depth (D/2) half the width. Use backing rod as required. Ensure surfaces are in good condition clean and free from oil, dust, loose materials including old sealant and release agents. Apply masking tape to surfaces where contact with sealant is not required. Tape should be removed before sealant cures. Smooth the surface of the sealant and ensure excess sealant is removed. Refer manufacturers curing or drying times before painting.


Heavy & Frequently Adjusted Fixtures

Heavy items are not to be fitted directly to the QT EcoSeries Wall Panel. They should have their own stand-alone supports or be tied to the supporting wall frame (eg. Clothes lines). Items subject to frequent handling (e.g. Flood-Lights and sensors) require a mounting plate, to be fixed across at least two or more frame studs to give longterm fixing support. The backing plate must be of a material that will offer, long-term weatherproof durability. If the internal lining is
already installed, the mounting plate can be installed externally prior to the installation of the QT
EcoSeries Wall Panel.

SUITABLE SUBSTRATES – when properly prepared

  • Cement Render
  • AAC (Autoclaved Aerated Concrete)
  • Fibre Cement Sheeting (Fibro/Blue board)
  • Rendered expanded polystyrene
  • Clay and Concrete Brickwork
  • Concrete blocks
  • Tilt panel walls
  • Other primed exterior surfaces

SUBSTRATE PREPARATION

  • Areas not to be coated should be masked and protected.
  • All surfaces to be coated must be clean, sound, free from contaminants including; oil, mould release, dust, dirt, silicone, mud, grease, salt, efflorescence, animal droppings and any loose or flaking material.
  • All substrates must be primed with Acryloc Prime Seal.
  • Apply the Prime Seal at the rate of 12.5-16.5m2/L and allow to dry (approx 30mins).

(Note: The concentrate form of Prime Seal must be diluted before use)

  • Imperfections and butt joints should be filled with Acryloc Patch with 5% Portland Cement added.
  • The surface may be coated with Acryloc Patch or Acryloc cement based Render, as required, before applying Acryloc Roll on Sand Texture.

APPLICATION

  • Acryloc Roll on Texture does not require thinning or dilution. Up to 300mL of clean water can be added to a 15L pail to adjust the workability if desired.
  • Mix thoroughly with a broad, flat stirrer, using an upward lifting action, or use a power mixer.
  • Power mixing is recommended as this will enhance the workability and give the best coverage.
  • A wet edge should be maintained throughout the application and day joints formed at corners, expansion joints or mouldings where they will not be evident after completion.

METHOD

  • Apply Acryloc Roll on Texture to the surface with a suitable texture roller. Load the roller generously and apply in strips 500mm-750mm in length.
  • Once five (5) or six (6) strips have been applied, roll across to even out the surface.
  • Finish in one direction for an even texture.
  • Repeat the above steps, only re-rolling 70-100mm into the previously coated area.
  • Work quickly and without interruption, laying off from the edge to avoid texture imperfections.
  • If a small area is missed, it is best to touch up when the area is dry. Running out of material midway through a wall surface should be avoided at all times. In this event, feather the edge and allow texture to dry, then marry in with new material.
  • Acryloc Roll on Texture should not be extended (spread) too far; otherwise durability and hiding power may suffer.

Important Notes

  • Care should be taken to keep Acryloc Roll on Texture off windows and adjacent surfaces that are not to be coated, as it can be very difficult to remove once allowed to dry.
  • Do not apply Acryloc Roll on Texture when rain is anticipated within 5 hours of completion of the days work, longer in damp, cold +/or humid conditions.
  • Avoid application in full sun, on hot surfaces or in hot windy conditions.
  • Application should be carried out on a day with temperatures above 10°C and below 32°C.
  • Coated area must be protected from damage until the completion of the project; finished work must be protected from rain, frost and severe weather conditions until fully dried.
  • Acryloc Roll on Texture is normally over coated with Acryloc Acryloc Armourflex for best colour accuracy, to improve durability and to reduce dirt pickup.
