Slab floors generally only require insulation if they employ an inslab heating or cooling system, and the requirements differ based on what type of slab your home uses Concrete slab floors Suspended slabs with an inslab heating system need to be insulated on the vertical edge of their perimeter with insulation that has an Rvalue of at least 1Timberframe floors are typically insulated with polystyrene boards or sheet insulation made from glasswool (fibreglass), wool, polyester, wool/polyester mix, and mineral wool Concrete slab floors are typically insulated with polystyrene boardUnderslab Bradford offers a range of high performance PIR boards and glasswool boards for underslab and under soffit applications Building insulation products are available in a wide range of densities, thicknesses, widths and lengths, and with a

Under Slab insulation is a fundamental part of the building envelope to comply with suspended slab, open subfloor R(floor structure) = 030 (Downwards) = 025 (Upwards)In the old days, not much — just dirt Eventually, contractors discovered that it made sense to include a 4inchthick layer of crushed stone under the concrete The crushed stone provides a capillary break that reduces the amount of moisture flowing upward from the damp soil to the permeable concrete Since theCommercial Brick Wall or Concrete Wall Insulation Download PDF Commercial Suspended Ceiling Insulation Download PDF Double Brick Cavity Insulation Download PDF Garage Door Insulation Download PDF Roof Insulation Cathedral or Skillion Download PDF Shed or Garage Insulation Download PDF Suspended Slab Insulation Download PDF
Safety & Security Reducing cooling, heating, and increasing insulation properties are part of the obvious health benefits of using concrete suspension slabs For example, concrete suspended slabs or raft slabs do not burn Therefore, if an unfortunate fire occurs near or at home, your concrete slabs will not be involved in this problem2 New slab – insulation above slab • The floor finish over the insulation can be either screed or boarding It is argued that a screed finish is more durable and can offer a modicum of thermal mass otherwise absent Board finishes, on the other hand, can be quickly installed and provide a quicker thermal response timeWhere a timber floating floor is laid on top of the concrete slab, insulation is fitted above the slab Suspended floors use either timber or beam and block construction For beam and block floors, the insulation is laid above the ground bearing structure and for suspended timber floors, the insulation boards are fitted between the timber joists
If the insulation is going below the slab, the damp proof membrane (DPM) is laid next, followed by the insulation, a polythene separating layer, and the concrete slab Depending on the use of the building, the slab can then be finished ready for use, or receive a screed suitable for a floor finish What goes under the concrete in a slabongrade home?Now the same technology can be used for insulated concrete floors, both suspended and slabongrade (FPSF), and pitched roofs, or insulated flat roofs with a Green Roof System to compliment them We are even seeing a trend for motivated selfbuilders and Green Building converts to seek Passivehaus or Passive House standard insulated foundations
