On Sunday, Melbournians woke up to the coldest morning in 18 years. Thanks to central heating, our Mustbethrifty House was toasty warm throughout the night.
However, if it weren’t for roof insulation, we would have shivered regardless of heating. I know this from our experience a couple of months back when Cheap Geek removed the loose fill insulation from our roof, after he suspected it of triggering off my allergies. It was autumn and the weather was still mild; we had the heating turned up and were huddled together on the couch, wrapped up in blankets.
Cheap Geek started laying down Green Stuf, a hypoallergenic* polyester batt. He installed insulation for half of the house**, then took a break for a couple of weeks before finishing off the rest. During those weeks, we noticed the change when moving from one part of the house to the other and the thermometer recorded differences of 0.5 to 1 degrees C.
Like most DIY jobs, the insulation is not 100% installed yet, but it’s enough to keep our heating in.
*While the Green Stuf is hypoallergenic and does not require protective equipment, Cheap Geek developed dermatitis on his arms and hands from coming into contact with residual loose fill. It’s best to wear a mask, gloves and a long-sleeved top when installing batts in the roof.
**No super special tools required: scissors, a couple of good camping lamps/torches and a trusty ladder…
