What is the purpose of having a raised timber floor? A timber raised access floor has the ability to reduce the amount of sound that 'leaks' between adjacent rooms. Access flooring uses either stud wall or partitioning to mount panels off of the floor, which creates a clear area beneath. What are the benefits of suspended timber floors? Unlike standard ground floor construction, suspended floors are not sitting directly on the ground. This allows air flow and ventilation to prevent the mould and dry rot that would otherwise occur over damp ground. However this air flow can leave the problem of draughts and cold in the house if not insulated correctly. TIMBER SUSPENDED FLOOR To meet min U value required of 0.18 W/m²K gk not more than 0.5 Ground preparation -Remove top soil and vegetation, apply total weed killer and 150mm min thick sand blinded hardcore, then either – (i) Provide concrete ground cover of at least 100mm thick or (ii) Prepare the ground to an even surface and lay a ground cover of concrete at least 50mm thick, on a damp-proof membrane of at least 1200 gauge polyethylene, laid on a bed of fine blinding material. Floor construction - min 20mm tongue and groove softwood boards or moisture resistant particle/chipboard grade type C4 to BS EN 312:2010 as required. Lay with staggered joints on 47mm x 195mm C24 grade soft wood joists at maximum 400mm centres, max span 4.31m. Joists to be supported off proprietary galvanized joist hangers built into new masonry walls or fixed to treated timber wall plates resin bolted to walls at 600mm centres. If required, floor joists also to be supported on 100mm x 50mm treated wall plates and DPC fixed to masonry honeycombed sleeper walls built on thickened oversite concrete or foundation, as required by BCO. Joists to be infilled with 130mm Celotex XR4000 insulation between joists fixed with proprietary clips. The top surface of the ground cover under the building shall be above the finished level of the adjoining ground. The underside of the floor joists not to be less than 150mm above the top of the ground cover. The underside of any wall plate not to be less than 75mm above the top of the ground cover. Ventilation of Floor Provide cross-ventilation under floor to outside air by ventilators in at least 2 opposite external walls of the building. Ventilation openings having an opening area of 1500mm² per metre run of perimeter wall or 500mm² per square metre of floor area whichever gives the greater opening area. All sleeper walls or similar under floor obstructions shall be of honeycombed construction or have similar provision for distribution of ventilation. The under floor space shall be free from debris. Ducts to be sealed using gas proof tap if they pass through the radon barrier. THIS IS A GENERAL GUIDE BASED ON NORMAL LOADING CONDITIONS FOUND IN DOMESTIC CONSTRUCTION. IT IS YOUR RESPONSIBILITY TO ASSESS YOUR DESIGN TO ASCERTAIN WHETHER ENGINEER'S DETAILS/CALCULATIONS ARE REQUIRED.
