In a new home the cost of insulating walls, ceilings and floors is very reasonable because sarking (applied under roof cladding) and fibreglass or rockwool batts can be installed during the construction phase when access is optimised.
The purpose of insulation is to block the flow of heat into and out of the building. Wood, brick, stone and concrete have good insulating properties because they are poor conductors of heat but engineered insulation products are far more efficient. Modern lightweight insulating mats and batts only 150mm thick will block the flow of heat as effectively as a solid brick wall.
You can purchase packs of insulation material from hardware stores and building supplies retailers together with free do-it-yourself installation instructions but beware; this is not a task to be taken lightly. Insulation products, especially those made from fine shreds of glass or stone, can cause severe skin irritation and bronchial problems. Masks, gloves and protective clothing must be worn.
Other popular insulation products include cellulose, polystyrene, urea formaldehyde, perlite and urethane and are applied either as loose fill, mats, batts, slabs and rigid boards (urea formaldehyde and urethane are usually foamed-in-place).
Crawling around in roof spaces can be hazardous because of the risk of electrical shock, heat exhaustion and physical injury so it is recommended that you get quotes from professionals before attempting the task yourself.
