HEG professionally installs ceiling, wall and underfloor insulation Tasmania-wide. We are the sole state-wide supply & install partner for CSR Bradford Insulation (Tasmania) and also have the northern Tasmania contract for insulating State Government public housing, to name some of our accomplishments. We take insulation seriously!
Why Outsource Insulation Services?
In a nutshell, we can install insulation in your house (whether being built or existing) more cost effectively and professionally than a non-specialist can and, we believe, do a much better job whilst using superior quality insulation. Additionally, we have the building code standards, insurances and industrial-grade equipment to ensure a safe job, and if any damage to property should accidentally occur, we fix it or arrange for it to be fixed. In other words, if you do the insulation job and injure yourself or your house, you may not have any recourse, and you may not be applying safety and efficiency standards.
Additionally, HEG brings these items to the table:
- First rate health and safety equipment, including high-grade ventilation masks, coverall suits, rubber-faced safety gloves, LED head torches, industrial-grade ladders, Lithion-Ion Impact Drivers (for roof screw removal, if required), first aid kits.
- Experienced and agile staff, providing time savings and aptitude for confined space work, which minimises the likelihood of damage to your ceiling.
- Knowledge and appreciation of relevant building code specifications with respect to electrical wiring and distance to keep insulation from flues, downlights and roofing material.
Insulating Existing Homes (retrofit)
If your house has no insulation at all...
If your home does not have any ceiling insulation (in particular), then please contact us regarding a competitive rate for retro-fitting insulation. Ceiling insulation is one of the “no brainer” big ticket items as it makes such a drastic and immediate impact on your comfort levels all year round, saving approximately 40% of energy related costs. Adding a good layer of insulation can:
- Add 6 to 7 degrees to the ambient temperature of your home in winter, and reduce temperatures by approx 5 degrees in summer.
- Dramatically reduce window condensation.
- Control mould and dust mites.
- Allow heat to travel further throughout the house.
- Provide an additional star rating for your house, which can increase the value of your house by $5500 (based on an Australian Government study in the Canberra housing market, 2008).
- Save $100’s annual on electricity bills (heating and cooling)
- Give a return on investment within 12-18 months.
If your home has no underfloor insulation, particularly in homes with exposed floorboards, then you are probably losing 20-30% of energy leakage through your floor, depending on the design and construction of your home. In southern states of Australia, it is often floor heat loss and draughts coming up through the cracks in the floorboard that is remedied by underfloor insulation.
In most cases, you will have a 24 month return on investment (and warmer feet!). We recommend R2-rated insulation for Tasmania, typically glasswool batts or expanded polystyrene. With exposed underfloor areas, we often recommend breathable plastic sheeting or sisilation to underlay the insulation to protect against the wind.
If your house has some existing old insulation...
Prior to 2003, the standard for homes that had ceiling insulation was to add 10cm thick R2-rated glasswool batts (or the equivalent in loose-fill blow-in insulation), or R3.5 batts. The modern minimum standard for ceilings in the Tasmanian climate zone is twice as thick - 20cm thick R4-rated batts. Over time, the old fluffy insulation becomes compressed, which means it loses its insulating properties. We often find 5cm-thick insulation in the ceilings of customer if the insulation was laid 15 years or more ago, which is the equivalent of an R1 rating. At this level, it is only one-quarter the current minimum standard and not doing a very effective job at insulating, and should be upgraded urgently.
From numbered items 1 through 4, this diagram shows:
- Typical height of ceiling insulation that may have been installed 15-30 years ago in a house in Tasmania. This could be glasswool batts, Rockwool blow-in or cellulose blow-in, often called “Charlie Fluff”.
- The insulation material sags and becomes compressed. Settling dust and debris in the roof may accelerate this process. Thinner insulation cannot insulate as well as thicker insulation in the same way that a thin doona on a bed cannot keep you as warm as a thick, plump doona.
- “Top-Up” insulation has been laid over the old insulation to keep the standard of insulation current (R4-rated).
- All new extensions and dwellings must have a minimum of R4 rating in their ceiling. #4 shows the relative height of typical R4 glasswool batts – 20cm.
