Fiber Cement Board: fiber cement flooring

Scyon™ Secura™ flooring
Secura External flooring
What is it?
An external structural flooring substrate for ceramic tile finishes over timber or lightweight steel floor joists.
Simple and fast to install, Scyon™ Secura™ exterior flooring helps give you peace of mind against moisture damage to balconies.
Where do you use it?
As an external substrate for tiled residential balconies and as an alternative to particle board, plywood or compressed fibre
cement.
What are the key benefits?
Security.
Scyon™ Secura™ exterior flooring is sealed on all sides with an advanced polymer coating that helps protect the board from
moisture related problems. A topcoat on the surface of the board provides good adhesion. The mesh reinforcement on the
underside enhances the heavy-duty performance of Scyon,™ adding extra strength and impact resistance to deliver a suitable
external residential flooring substrate.
Easy to install .
At about 40kg and 2,700mmlong by 600mm wide, Secura™ exterior flooring is about 15% lighter than compressed sheet
(per square metre) and can be tucked under the arm and carried like a large surfboard (by two people). It’s also tongue and
grooved, which delivers engineered joints and eliminates the need for timber trimmers under these joints.
Speed . For balconies that aren’t over habitable rooms – verandas for example – no additional waterproofing membrane is
needed once Secura™ exterior flooring is installed2.
For balconies over habitable rooms, a waterproofing system needs to be applied.
Made from Scyon.™ Secura™ exterior flooring is made from Scyon™, the advanced lightweight cement composite with
heavy-duty performance.Not only is it resistant to damage from termites, rot and fire1, but it can also be gun nailed and iseasy
to cut – like timber.
1 When installed and maintained correctly and to the extent set out in James Hardie’s published literature current at the time of installation.
2 A priming coat is recommended to be applied over all sheets before tiling, refer to the manual.
Secura Interior flooring
What is it?
A heavy-duty but lightweight structural flooring substrate that does double duty – it can be easily used for tile, vinyl and carpet
finishes over timber or steel floor joists in both residential general interiors and wet areas. Simple and fast to install, Scyon™
Secura™ interior flooring is the easiest way to get top protection against moisture damage to all interior floors.
Where do you use it?
As a substrate for direct fixing of tiles, vinyl and carpet in residential floors and wet areas, as an alternative to particle board,
plywood or compressed fibre cement.
What are the key benefits?
Speed . Secura™ interior flooring is 15% lighter per square metre than conventional 15mm compressed fibre cement, which
makes it easier to handle. And because it’s made from Scyon™, there’s no need for pre-drilling and screwing. All told it can be
up to 40% faster to install than compressed.
No fuss. The 19mm tongue and groove joining means it is compatible with other 19mm flooring products and eliminates the
need for timber trimmers along the tongue and groove joint. The moisture-resistant sealer on all sides combined with the
moisture-resistant properties of Scyon™, removes the need for full floor waterproofing outside enclosed shower areas. And
unlike some timber products, tiles and vinyl can be directly fixed without the need for an underlay sheet.
Security. Secura™ interior flooring is resistant to damage from moisture, so if rain holds you up during construction and the
roof’s not yet on2, the product won’t need replacing or sanding because it’s warped and twisted, like some timber products1.
This resistance to moisture damage also means that if there is a waterproofing failure sometime in the future, then the
Secura™ interior flooring will continue to perform, even if it gets wet. The strong,no-squeak feel of Secura™ interior flooring
also gives a solid impression without the weight and cost of concrete. Secura™ interior flooring has a 10-year product
warranty1.

2 Exposure to the elements should not be longer than three months.

fiber cement board, fiber cement flat sheet for Baker board,

Backer board, also called backing board, is a type of submaterial used under a variety of building projects, most often, tile projects. The most popular type of backing board is made of compressed cement pressed between two sheets of fiberglass. Another type of backing board is one-half inch (1.3 cm) water resistant greenboard. The determining factor on what type of backer board to choose is the area where it will be installed.

Backer board does not add any structural strength to the floor or walls. If strength is a concern, reinforce the area first, before adding the additional weight of the board. Cement board, in particular, is heavy, so it is important to place it on strong subflooring.

The use of backing board makes tiling an easy do-it-yourself project. Prior to the development of backing board, laying tile required the person handling the job to lay a thick mud bed withmortar. This created a waterproof barrier and provided a level area to install tile. Installation is simple with backer board, which it is screwed directly into the sub floor. A thin application of mortar under the backer board fills any voids between the board and the sub floor.

Greenboard is water resistant, but not waterproof. Greenboard is not for use in areas where it will be exposed to a great deal of moisture. While it will do well in areas with some moisture, such as on a bathroom wall or under a backsplash, when exposed to a great deal of moisture, the greenboard can break down and disintegrate.

Cement backer board is a much more durable material. Typically available in one-half inch (1.3 cm) thickness, cement backing board is impervious to moisture. Cement backer board is the ideal choice for showers, bathroom floors, and other wet weather applications. Cement backing board is long lasting; many types advertise a projected life of 50 years. It is also resistant to mold, rotting, and warping.

The major disadvantage of cement backer board is that it is heavy and can be difficult to handle during installation. Available in 3 by 5 foot (.9m by 1.5m) and 4 by 6 foot (1.2m by 1.8m) sizes, depending on the manufacturer, bringing the backing board into a small bathroom or laundry room for installation can be challenging. It is often necessary to bring the full sheets of backing board into the area where it will be installed to make accurate cuts along pipes and other fittings.

Fiber Cement Flooring ( Fiber Cement Board used for Subfloor and Underlayment)

Definition: Subfloor refers to（适用于） the bottom-most structural floor underneath the decorative or "finish" floor.

Finish flooring, such as ceramic tile, solid wood, laminate（强化地板，复合地板）, engineered wood, and others, all employ subfloor in their construction; after all, they need to rest on something.

In some cases, subfloor is the only layer between the decorative flooring and the joists.

Typically, though, an underlayment--plywood or cement board--rests between the subfloor and the finish floor.

Examples:

The floor installers were forced to put down a layer of quarter-inch（6mm thick） plywood underlayment on the subfloorbefore putting down the Pergo(瑞典柏丽地板 www.pergo.com ).
