A Best Practice Approach To Insulating Suspended Timber Floors Fintan from our Technical Team discusses the thermal loss issues associated with suspended timber floors and outlines a best practice approach to tackling them At the turn of the 18th century, when construction techniques moved from boarded floors installed directly on the groundThe constructional details from the bottom of the foundation to 400mm above finished floor level and include the abutment of both floors (For the purposes of this drawing, show a minimum 15 metres width for each floor type) (b) Indicate on the drawing a design detail to show the cross ventilation of the suspended timber floorE7 Intermediate floor between dwelling;

Ground 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 joistNHBC requires ground floors to be constructed as suspended floors in the following situations where the depth of fill exceeds 600mm, as described in Chapter 51 'Substructure and ground bearing floors' (Design) where soil swelling may occur, as described in Chapter 42 'Building near trees' on sites which have been subject to vibratory groundE Exposed floor (normal) P1 Ground floor

Ground bearing slabs should not be used in ground conditions where heave can occur or where the foundation depth is greater than 15m Under these circumstances a suspended floor construction should be used Site preparation The ground beneath the floor should be stripped of all topsoil, organic matter or tree roots prior to filling and compactionSuspended timber floor As a requirement of the Building Regulations the structure should be protected against the growth of weeds and other plantlife The ground should have a layer of concrete poured across and there should be a ventilated gap of at least 150mm between the underside of the timbers and the concrete, to prevent moistureA – Standard Designs Transmission Typical Details for Optical Ground Wire Splice Structures 114 41 6157 – Standard Design Transmission Lines Type 3TD 115Kv 3pole Tension Dead End Structure 115 41 9002 Rev N – Transmission Line Standards Barbed Wire Gate For Right ofWay Fences
The timber floor structure will be shown in detail on the plans and drawings These must be drawn according to SANS 100 which specifies how timber buildings should be built and there should be at least 450 mm between the joists and the ground Upperfloor suspended timber floors are built in a similar way although the floor joists may beE10 Eaves (insulation at ceiling level) E11 Eaves (insulation at rafter level) E12 Gable (insulation at ceiling level) E16 Corner (normal) E17 Corner (inverted) P4 P5 Roof;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 mm
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 moreGround floor beam details (a) str/17 december, 17 str/31 december, 17 str/32 december, 17 str/33 december, 17 third floor beam layout plan str/34 december, 17 any variations or substitutions of materials or details from those indicated on the drawings may only be made with prior approval of the engineer b foundationThis chapter gives guidance on meeting the Technical Requirements for suspended ground floors including those constructed from insitu concrete precast concrete timber joists 521 Compliance 522 Provision of information 523 Contaminants

Structural support, in suspended floors the system has a support structure that carries and transfers the load to the footings The structural support for suspended slabs for the ground floor is usually dwarf masonry walls For timber floors the substructure generally consists of joists, bearers and engagedDifferent types of ground floor suspended flooring Suspended timber floors need to have spaces underneath ventilated via air 'bricks' through the outer walls and gaps in any internal walls so that the air can move across the building underneath the floors to prevent the build up of moisture in the timber which could lead to fungal attackConstruction Studies drawing detail of suspended timber floor
