Attic as if synonymous with hiding rats or spiders. Inevitably because of the area at the bottom of the roof was left empty and dark. It is understandable, because the function is only a cushion of air to the road and out of the wind. If ever used, at most, to the thrift store.
Later, with increasingly limited land, the attic is no longer left empty and “lonely”. He could be used as a playroom, study room, even bedroom. Includes a mini work area or office.
The new functionality makes the design attic refurbished. Well, it is necessary for a strong attic structure. Various materials can be made to make the structure of the attic. Such as wood can be an option for attic structure. Besides easy to work with and connect wood cutting principle is also relatively easy to buy on the market.
In terms of strength, the wood usually can withstand loads of up to 100 kg/cm2. If a load of people and furniture still under power of wooden bear, then you can still use it as a structural timber loft workspace.
But wood has its drawbacks as well. As you know, the wood easily eaten by termites. Also vulnerable shrinkage expansion due to weather changes. It is necessary to treat ( treatment) with a special polish or liquid residue antirayap.
The other option is a steel shaped cross-sectional profile of the letters H.I.U. and C. Of course the steel will not be eaten by termites. Another advantage, high appeal. Ability to form the beam span reaches 6 feet, pole smoking rooms and make the connection.
Not that steel does not have a shortage. The price is still relatively expensive. Besides the installation requires special steel expert, not a common blacksmith. And last but not least important, the material is corrosive if not get paint protection. Another case if it is protected by zinc and aluminum.
Same with the principle of mounting wood frame, steel uses a specific size module mounting systems and beam joists. Beam functions deliver loads to the beam pedestal floor attic. While joist floor load evenly split.
Another alternative is a concrete floor structure. There are two options. Conventional concrete is made by casting in place. While precast concrete is a composite that has been processed at the plant. Builders you simply snap in place.
