Suspended timber floor detail uk-The main driver for installing suspended timber floor insulation will be to improve thermal performance To plan what thickness of insulation you'll need for a suspended timber floor you must calculate its UValue In England and Wales building regulations suggest the floor should achieve a UValue of 025 W/m2K or less, if possible To define this, you'll also need to work outSelecting Timber Floors Floor Structure Floating Floor type Underfloor Heating Thickness Robust Detail Solid timber joist Timber deck on resilient battens No 384mm EFT2 4235mm EFT8 Engineered Ijoist Timber deck on resilient battens No 403mm EFT1 4235mm EFT7 Wet screed No 4516mm EFT4 Dry screed board Yes 346mm EFT5 Metal web joist Timber

Timber joists are widely used within internal floor and separating floor construction, both in residential and commercial applications Our range of timber joist floor solutions include cavity insulation, highperformance Gyproc plasterboards and Gypframe sound insulating bars Our solutions maximise acoustic and fire performance, to both meetMany buildings with suspended timber floor suffer from rot and insect attack in the ground floor timbers due to poor sub floor ventilation We look at this more thoroughly in our air bricks and air vents project , but quite simply if air bricks become blocked with debris or ground levels are raised this cuts off the air flow and water leaks may also occurSuspended concrete floor This construction is similar to the timber floor above, but uses either precast concrete planks or small precast concrete beams with concrete blocks laid between the beams They can normally span greater distances than timber joists Ventilation is required in the same way as a suspended timber floor

Diagram of suspended timber floor with underfloor heating pipesGround Floor – Hollow or Timber Floor Hollow floors, also known as suspended or timber floors, are simply timber joists suspended across and supported by load bearing walls under the floor The ends of these timber joists are built into, or suspended by joist hangers from the external walls of the property suspended timber floors located above an unheated space, where the insulation is installed below the floorboards or timber decking timber floors situated above an unheated integral garage, unheated

A suspended floor is a ground floor with a void underneath the structure The floor can be formed in various ways, using timber joists, precast concrete panels, block and beam system or cast insitu with reinforced concrete However, the floor structure is supported by external and internal wallsStudies of the site, carried out in accordance with Chapter 41 'Land quality managing ground conditions' should be taken into account in the design of substructure Where the depth of infill exceeds 600mm, the floor must be designed as a suspended floor, as described in Chapter 52 'Suspended ground floors' (Design) Loadbearing partitions should not be supported off ground bearing floorsTimber suspended ground floors, including the decking material, shall be designed to (a) support self weight, dead loads and imposed loads (b) transmit loads safely to the supporting structure (c) not deflect unduly
To get the timber suspended floor to act as a screeded floor and to give out more heat, the air gap between the insulation and the floor boards should be filled with a lightweight screed mix The infill is normally 101 sand/cement mix at a height of 25 mmWe have a wide range of floor insulation boards, including solid ground floor insulation, suspended floor insulation and soffit insulation We also have insulation boards suitable for more specialist flooring applications, for example heavy duty floor insulation and insulation for cellar and basement floorsAnimated Building Section Details 1 of 21 Strip Foundation & Concrete Ground Floor 2 of 21 Suspended Timber Ground Floor 3 of 21 Linked Floor 4 of 21 Concrete Ground Floor – Timber Frame Wall 5 of 21 Window Cill – Concrete Cavity Wall 6 of 21 Window Cill – Timber Frame Wall 7 of 21 Door Threshold – Concrete Cavity Wall 8 of 21 Eaves Detail – Concrete Cavity Wall 9 of 21

Precast beam and block floors Site preparation All topsoil and organic matter should be removed from beneath the suspended floor The ground level should be at least the same as the external ground level unless the ground below the floor is free draining Alternatively, a DPM linked to the DPC can be providedTable 2 – Separating floors VFT1™ timber ijoists and floating floor treatment VFT2™ timber solid joists and floating floor treatment VFS1™ steel deck and insitu concrete and floating floor treatment List of Robust Details™ IdciA 13 S_IdciN05 1233 Page 3 4 of 8 April 13® Update Introduction robust details Table 3a – Combinations of Robust DetailsIf the new wall passes through an existing timber floor, the key thing to pay attention to is to ensuring that any new timber that is in contact with or supported by the new wall is above the line of the damp proof course Also, if there is ventilation in the void under a suspended timber floor then air bricks in the wall are likely be needed to maintain air flow through the void
Junction E5 Ground floor; The BRANZ Technical Helpline often receives queries for designing and building suspended timber floors and dealing with uplift Nine of the most common questions are answered here a031 2 online Figure 1 Suspended timber floor joist layout (redrawn from NZS Figure 72) Figure 2 Lateral support offset from brace line (redrawn from NZS Figure Timber deck finish can also be used – if this is specified a vapour control layer must be included in the design under the timber deck A void is left under the floor of at least 150mm between the soil and underside of the beam If heavy clay soil is present it is good practice to increase the void depth to as much as 225mm or possibly more
Suspended timber floors, which are typically found in older houses, are normally made from timber floorboards which are then attached to joists just above the foundations of a house This creates a small gap and allows ventilation and air movement to prevent damp forming in the timber joists It's also common to have suspended concrete floors in a domestic andA selection of floor detail drawings including block and beam floors, timber suspended floors, solid ground floors and upgrade floor details Drawings are directly downloadable in Jpeg (1600 by 10px), DXF and DWG (cad) formats Note The Detail Drawings are applicable to
