More Info On Floor Insulation

The subject of floor insulation often emerges as a measure to arrest the loss of heat occurring through the floor-highlighting the lack of attention floors receive in comparison with roofs and walls, owing to the lowest percentage of heat loss through floors, when it comes to insulation-making floors the final station of the insulation circuit, encasing the entire house with thermal insulation. The nature of floor construction, the substrate layers, and the type of flooring have a significant role to play in the choice of material and in charting out appropriate method and measures to effect suitable floor insulation.

Elevated Timber Floor Insulation

The decision to apply the insulation under the floor or to create a layer of insulation over the floor substrate is contingent upon floor designs, which are chiefly distinguished by being broadly categorised as belonging to either the elevated wooden floor or solid floor category. Desirable results are achieved with insulation being applied under the elevated also commonly known as suspended floors employing glass-fibre batts or rolls among the many popular approaches. Rolls and Batts are equally effective when placed between floor joists employing the top to bottom approach, which invites tedium as it involves removing the flooring and the sub-floor layer of the substrate before reaching the floor joists. However, loose-fill insulation is a far more effective option owing to the breathable nature of the insulation layer.

Concrete Based Substrate and Solid Floor Insulation

Solid floor insulation procedure places the insulation layer between damp-proof membrane (DPM) and the layer of screed upon which hosts the top or final layer of the floor, above the sub-floor level of the substrate layer. In other words the insulation is placed below the underlayment layer of screed above which the flooring rests, is a well-established convention in solid floor insulation procedures, which besides being uneconomical is labour intensive reaching the damp-proof membrane (DPM) substrate level by unearthing the floor and the screed layer. Fire and moisture resistant insulation boards made of polystyrene incorporated with compressive and tensile strength are an attractive option to form the insulation layer in solid floor insulation. Polyurethane spraying is the more expensive and superior option than applying insulation-screed-solutions as its heat energy transmission is the lowest among all products in circulation, and it allows direct application on concrete in varying degrees of thickness as an insulation layer.

Counting Benefits

As mentioned earlier floor insulation does complete the circuit of insulation sealing up the last exit point for heat loss, thereby enveloping the entire house with thermal insulation. Insulation lowers the sound infiltration caused by outdoor sounds as well as indoor sounds arising from wooden floorboards. Draughts infiltration is considerably lowered as a result of insulation, which can be further reduced or even eliminated by filling the gaps between the floorboards with draught strips, and sealants. Fire and mould resistant floor insulation material are capable of providing additional safety and longevity to the existing wooden flooring.
