Suitable for Passive House & low energy builds. slab, below a cement based screed on a concrete slab with a hardcore base, above a suspended concrete floor and between the joists of a suspended timber floor. Up to ten percent of a home's heat may be lost through an uninsulated, poorly insulated or draughty floor.
Concrete floor slabs are a standard way to embed thermal mass in passive design, but is it always the right approach? Then in summer, the well-designed building's perfect shading angles exclude all sun, allowing the thermal mass to soak up any discomfort inside the house, whereupon it is dumped to the cool night air
Many older houses with suspended timber floors have big draughts and inadequate floor insulation; this can cause cold feet as well as higher energy bills. Installing underfloor insulation can address both these problems and give a payback on your investment in 5 years or less depending on whether you do it as a DIY job
Insulating suspended timber floors. Insulating timber floors part 1. Question: Could you please advise me on materials for under-floor insulation? We live in an Edwardian house with standard floorboards which are fixed to joist? What can we use? I was told about fibreboards. Answer: Ideally a fibrous insulation such as

Suspended slabs are formed and poured in situ, with either removable or 'lost' non-loadbearing formwork, or permanent formwork which forms part of the reinforcement. . Take care to construct continuous physical barriers, and always provide full inspection access to the junction in houses with raised timber floors.
Suspended timber floor construction refers to the traditional Australian domestic building method utilising footings and stumps, a framework of timber bearers and joists with the flooring fixed on top. In more recent years, concrete slab construction has become more widespread for cheaper homes, particularly on flat sites.
Options for floor insulation. The type of floor insulation used will depend on whether the floor is concrete slab or a suspended timber-frame floor. On this page: Insulating timber-framed floors; Insulating concrete slab floors. Timber-frame floors are typically insulated with polystyrene boards or sheet insulation
insulation within a suspended timber floor Suspended timber ground floors can be easily upgraded. A range of insulation materials can be fitted between the joists to make a quick and efficient contribution to reducing overall heat loss. - Rigid slabs can be friction fitted from above against nailed timber bearings to the
The next step is to assess the condition of the joists and the ground below the floor. It is essential to ensure good cross ventilation is retained. If there is clear earth on the ground below one should consider applying damp proof membrane on top of this to help further reduce humidity within the void. Upgrading Suspended
With so many resources invested in the existing housing stock, and with the banking system still dysfunctional, we're unlikely to see any recovery in new build for some . Each 2c spent on roof insulation saved one kWh, while the equivalent figures for floor insulation and thermal bridges were 2.6c and 4.5c respectively.
A different material, for example a timber floor, cannot absorb and store as much heat, so what heat it does absorb is released quickly. Because of this it is important to ask an expert in solar design, such as a designer, architect or building scientist who specialises in passive solar design, to advise you on the best option
Architype are leaders in designing Passivhaus buildings and timber buildings, so the majority of the Passivhaus buildings I presented were timber The services and circulation core is reinforced concrete, the floors are hybrid engineered timber reinforced concrete and the frame and external shell is
