1 Sound Insulation Quality Thermal Insulation Fire Resistant PowerFloor

2 What is PowerFloor? Hebel PowerFloor is a lightweight autoclaved aerated concrete (AAC) panel that can be fixed to timber or steel joists. It provides the feel of a rigid concrete floor but with the advantage of providing an instant working surface, along with acoustic and thermal benefits. Benefits No Propping required as panels are supported by permanent floor joists Rapid Installation with typical placement rates of 750 sqf per day Fire resistant -panels are totally inorganic and incombustible Superior Acoustic insulation creating a sound barrier between floors Accuracy of manufactured panels results in less on site cutting and wastage No pre-drilling is required as all fixings can self tap through panels Excellent load carrying capacity Excellent load capacity as this system can support up to 140 psf uniform loads Smooth finish surface Smooth surface provides an excellent substrate for any type of floor covering without additional preparation Lightweight panels can easily be handled on sloping sites with difficult access where a suspended floor is required Non-Toxic - as with all Hebel products, Hebel PowerFloor does not contain any toxic gases or substances Pest and rot resistant - panels are not a food source for insects, vermin or fungus. Components Hebel PowerFloor is manufactured from lightweight autoclaved aerated concrete. They are reinforced with one layer of steel mesh and have a stock size of flat edges by 96 x 24 x 3 inches and weigh approximately 10 psf. Panels can be cut dry on site using a circular saw with a segmented diamond blade AAC Adhesive is used on all panel edges for edge jointing of panels Construction adhesive is used to bond panels to all supporting joists with a minimum bead of 3/16. Two beads are used at end butt joints Screw fastenings - Bugle head screws (14-10 x 4 ) for timber joists and hex head self-tapping screws (14-10 x 3 3/4 ) for steel joists, are used to fasten panels to joists with two screws per panel per joist. Using screws at panel end joins is optional depending on width of joists. See Details A & C for steel and timber joist fastenings Design Considerations Structural Design Hebel PowerFloor is designed for a maximum uniform loading of 140 psf on a maximum joist spacing of 24. Typically, closing of joist centers to 18 provides a stiffer floor with optimum results. Additional blocking between joists should support all concentrated loads and the localised bearing stress on the AAC should be limited to 340 psi. must be designed in accordance to selfweight of the AAC panel, dead and live loads (by adopted building code). Acoustic performance Hebel PowerFloor has been laboratory tested to establish sound insulation characteristics and these are shown in table 5. Thermal performance Thermal resistance is given in table 3. Fire resistance Fire resistance levels are shown in table 4 for fire above. Delivery and Storage Hebel PowerFloor are supplied in bundles of 10 pieces on pallets in plastic wrapping. Each pallet can weigh up to 1,475 lb. so careful placement is required if placed on the structure under construction. Pallets can be placed two high if space is at a premium. Panels should be kept dry before placement to reduce handling weight. Installation Typical panel fixing details are shown in details A, B & C. Panels are installed in stretcher bond with a minimum overlap of 24. Construction adhesive is applied to each joist and AAC Adhesive Mortar is applied to panel edges. Panels must be placed with minimal sliding on joists.

Screw holes are filled with AAC Adhesive and any chips on panel edges should be filled with AAC adhesive or AAC Patching Mortar. Detail E. Fixing to Timber s at change in Orientation 2 min. Construction adhesive Control joint Where cutting of panels lengthwise is required, the minimum width of cut panel allowable is 10 to ensure sufficient reinforcing is located in each panel. If a narrower piece is required against a floor edge, the last two panels should be reduced in width so that both exceed 10 in width. All reinforcing exposed on cut panels should be coated with anti-corrosion agent x 4 MP bugle head batten screw Timber joist 1 3/4 min. Should I use a fitted or platform floor? Fitted and platform type floors are shown in Detail F & G. Fitted Flooring is placed between the framed walls, after the walls are erected. Fitted floors are required where the bearing stress on the floor panels would exceed 340 Psi, either on top of the joists or blocking under the panels, or under the bottom plates of partitions. Fitted floor panels should finish with a 3/8 minimum gap between the panel and the wall framing. Control Joints Movement control joints should divide the floor panels into separate floor diaphragms of a maximum of 20 ft long in either direction. See detail D for typical control joint details. Control joint locations should be as follows: At changes in panel and joist orientation as shown in Detail E. At load bearing bracing walls to ensure that the floor diaphragm is continuous between bracing walls. Over support walls or beams. At 20 ft maximum spacing. Detail F.

It can only be used where bearing stresses are less than 340 Psi. To give the equivalent holding down capacity required by structural specifications, bottom plates should be fastened with x 4 Bugle head screws at maximum 12 centers. All bracing walls on platform floors require bottom plates to be fastened with bolts through the Hebel PowerFloor to blocking on the underside as shown in Detail H.

6 Wet Areas All wet areas require the waterproof membrane over the Hebel PowerFloor. This includes exterior decks, tiled areas in bathrooms, laundries etc. Penetrations and Notches in floor panels Hebel PowerFloor can accommodate a maximum circular penetration of 4 diameter without compromising the panel strength. Where multiple holes are required, these should all be in a straight line parallel to the long panel edge. The maximum width of notching in a panel is a quarter of the panel width and no notching is allowed in panels less than 16 wide. All openings in floors for pipes/services, etc. should have full blocking to support panels around openings and movement joints should be installed around all services.
