Loft insulation is thermal insulation installed in loft spaces and sloped roofs. Common loft insulation types include mineral wool, cellulose and fibreglass in the form of loft insulation roll, batt, or loose-fill.
Key benefits of high-quality loft insulation include improved temperature regulation, energy savings, and moisture control. By creating a thermal barrier, loft insulation prevents heated or cooled indoor air from escaping out of the roof. Loft insulation also guards against condensation build-up. Installing loft insulation to recommended coverage and R-values provides decades of savings on heating and air conditioning.
Roof insulation options include rigid foam boards, fibreglass batts, and foil-faced insulation. Adding appropriate roof insulation improves temperature regulation within a building. By resisting conductive, convective, and radiant heat flow through the roof, insulation maintains warmer indoor temperatures in winter and cooler conditions during summer heat.
Effective roof insulation also controls moisture accumulation by limiting condensation from water vapour contacting cold roof materials. Ventilation works alongside insulation to circulate air. Preventing dampness guards against leaks, mould, rot and ice dams.
Cavity Wall Insulation
Cavity wall insulation injects vital thermal protection into hollow blocks and concrete walls prone to convection currents. Blown-in insulation fills narrow cavities through small holes for convenient retrofits. Loose-fill options like cellulose and fibreglass conform to internal void spaces for full contact and coverage inside walls. Tiny air pockets within the spun fibres resist conductive and convective heat flow.
Cavity wall insulation can also help to tackle moisture and pests. Treated cellulose applications control humidity that compromises insulation and causes mould. Water-resistant formulas further resist both moisture and insects drawn to organic materials.
External Wall Insulation
External wall insulation is available in rigid boards or panels on the exterior side of walls. Common insulation types used externally include expanded polystyrene (EPS) and extruded polystyrene (XPS) foam boards and mineral wool insulation.
Installing external wall insulation provides several notable benefits. For example, full wall surface coverage is achieved without thermal breaks from wall studs. External wall insulation also enables the use of thick insulation boards, increasing R-values and thermal performance. Uninterrupted coverage and higher insulation levels together help regulate interior temperatures.
Several major types of floor insulation exist to enhance energy efficiency and comfort. Fibreglass batts and rolls provide an affordable option made of heat-resistant glass fibres bonded by thermosetting resins. Fitted between joists, they offer good thermal resistance, are non-combustible, and do not promote moisture accumulation when installed properly.
Rigid foam boards made of extruded polystyrene (XPS) or expanded polystyrene (EPS) also insulate floors effectively. With high R-values and compressive strengths, foam boards withstand backfill pressure when used under concrete slab foundations while blocking moisture and air infiltration. Also, sealed edges prevent thermal bridging.
Loose-fill fibreglass, rock wool, and cellulose work well for existing spaces. Poured between joists and then covered with boards, dense-pack loose-fill insulation reaches voids that batts can miss. Environmentally friendly options like cotton insulation are also growing in popularity.
Installing rubber and foam pipe insulation is beneficial for energy efficiency and cutting costs in any space. Rubber and foam pipe insulation comes in wrap sleeves that can be cut to fit snugly around water pipes, air ducts and heating pipes to form a protective barrier. The foam material prevents heat loss as liquids and air pass through the piping system.
Insulating pipes with foam or rubber enables water to stay hot for longer as it travels from the water heater throughout the building. This means less energy is wasted reheating water to the desired temperature at faucets or appliances. Pipe insulation foam and rubber also help prevent freezing and bursting in pipes that run through unheated spaces like a loft or garage. By doing this, it regulates temperature fluctuations to keep water safely flowing.
