Mineral wool like this Rockwool from Wickes is dense, sturdy, and provides wonderful hearth resistance (withstands temperatures as much as 1,000°C). Mineral wool insulation can also be an excellent acoustic insulator. Nevertheless, in comparison with fibreglass, it’s heavier, may be tougher to work with, and requires comparatively thick layers to attain the required thermal efficiency. Its thermal conductivity usually ranges from 0.034 to 0.040 W/mK.
Fibreglass (glass wool): Light-weight and inexpensive, fibreglass is a typical alternative for DIYers, particularly for insulating lofts. It’s comprised of recycled glass and provides good thermal efficiency, usually round 0.044 W/mK, although higher-density batts can provide 0.034 W/mK. It’s much less strong than mineral wool and liable to moisture absorption and sagging if not put in correctly.
PIR (Polyisocyanurate) boards: Manufactured as inflexible insulation board, PIR is among the many most thermally environment friendly merchandise obtainable, with conductivity as little as 0.022 W/mK. They’re perfect for insulating flooring, partitions and pitched roofs, the place house is tight. PIR foam is closed cell, moisture resistant and sturdy. Sadly, it’s comparatively costly and tough to put in in irregular areas.
Polystyrene beads (EPS): Typically utilized in retrofit cavity wall insulation, EPS beads are blown into the cavity, forming an insulation layer that resists moisture and mildew. They’re appropriate for partitions uncovered to driving rain, however include greater prices and hearth security considerations, relying on the system.
Cellulose Insulationis an eco-friendly materials comprised of recycled paper handled with hearth retardants. With a thermal conductivity of round 0.040 W/mK, it is usually blown into cavities and lofts and provides good efficiency, however, settles over time.
Spray foam (Polyurethane): With wonderful airtightness and good thermal resistance, spray foam sounds perfect. Nevertheless, on account of condensation issues it has change into controversial as a result of potential impacts on mortgageability.
Sheep’s wool: A pure insulation and sustainable alternative that’s nice at regulating moisture and offering respectable thermal efficiency (round 0.035–0.040 W/mK). Sheep wool insulation like this Thermafleece on Amazon is secure to deal with, biodegradable, and may take up moisture, however be careful for bugs and excessive prices.
Every materials provides its personal stability of insulation value, efficiency, and suitability. Slightly than differentiating one product as higher than one other, it’s extra about placing the precise product in the precise place.
For instance, when you’re insulating a loft with ample house, fibreglass or mineral wool is likely to be finest. However for tight cavities or the place thermal efficiency is important, PIR boards would be the most suitable choice.
2. Add insulation in the precise areas
Loft insulation – Warmth rises, and with round 25% warmth loss, lofts are some of the vital areas to focus on. Laying rolls of mineral wool or fibreglass between and throughout ceiling joists is customary apply. For heat roof designs, inflexible PIR boards may be put in above or beneath rafters however keep in mind to keep up air flow paths. A specialist various for insulating lofts is blown cellulose insulation. The target is to distribute the unfastened fill materials evenly to create a thick insulating layer.
Wall insulation – Partitions even have a possible for vital warmth loss. Cavity wall insulation is in-built throughout building utilizing inflexible boards or mineral wool batts. For present properties, blown-in insulation of both mineral wool or EPS beads are widespread. Strong partitions will also be insulated internally with inflexible boards or externally with insulated render methods topic to good high quality design.
Flooring insulation – Floor flooring may be insulated utilizing inflexible PIR or EPS boards laid over or beneath the slab of recent builds. Suspended timber flooring can have insulation fitted between the joists, although it’s important to keep up air flow to forestall rot.

Closing in damp with insulation will lure moisture, doubtlessly inflicting rot, mould or injury to the insulation materials. Be careful for thermal bridging – the place gaps in insulation enable warmth to bypass the insulated layer. This typically happens with dangerous becoming or round junctions resembling window reveals, and may result in mould development.
4. Inject cavity wall insulation for a fast answer
Specialist contractors drill small holes within the mortar joints and blow in mineral wool, or polystyrene beads as cavity wall insulation. It’s comparatively fast, however the wall should be in good situation, and supplies needs to be chosen based mostly on publicity threat.
5. Set up inflexible foam boards in partitions and flooring
Widespread in partitions and flooring, insulation boards are mounted on to supporting timbers or blockwork or laid over flooring slabs. They require exact becoming to forestall gaps and thermal bypass and might have joints taped to forestall interstitial condensation.
