Karawara Insulation replacement can save you money!
With rising costs of electricity and fuel now is the time to see how you can save. One way is to replace old insulation, you’d be surprised just how much heat & cool leaks from your home and how that can really affect your bills. If you run your air-con heaps but find your house just will not stay cool then maybe it is time to replace the insulation with a better quality one.
The saying goes that time is money, but we’d say that energy is money.
When should you replace insulation?
When you have to run your air conditioner longer because the rooms in your home are trapping in heat, or when you have to blast your heater to combat the air leaks in your attic, the energy usage adds up. You’ll notice higher utility bills month after month.
So exactly how much money and thus energy can you save by insulating parts of your home such as your basement, crawlspace, and attic? To answer that, let’s look at the guidance from Energy Star.
Determining your potential savings requires that yours is a “typical” home in the United States. Per the Residential Energy Consumption Survey or RECS through the U.S. Energy Information Administration, Energy Star defines a typical home thusly.
Your home was built between 1970 and 1989 and has four bedrooms. The property has a conditioned floor area up to 1,700 feet. Your home uses stick construction such as wooden rafters, joists, and studs. The attics, if they are insulated, feature blown-in insulation while the walls have fiberglass batts.
Roof insulation case study: Clarkson 2007 Home
A 2007 First Home Buyers’ build, the roof insulation remained untouched since construction. The home was a double brick, tin roof with old fibreglass ceiling batts. These had compressed over time and were infested with rodent debris. As they were so old, they offered very little thermal performance (R1.4 estimated).
The cost of works were estimated as
Insulation Removal & Roof Cavity Clean – $1,500
Supply & Install Bradford Gold R5 Batts – $1,960
TOTAL = $3,460
Estimated cost savings after roof insulation works = $540 – $670 p.a.
Estimated ROI = 5-6 years
