Being a Melburnian, you know exactly how harsh weather conditions can be. On one side of the spectrum, you have beautiful sunny days, and on the other hand, you can face cold winds blowing into your home. If you’re tired of spending tons of money on energy and having your family shivering even at home, installing the best wall insulation in Melbourne will be a lifesaver for you.
But when you visit your hardware shop, you face a wide variety of products. And the truth is that insulation that worked perfectly in a brand-new home of your neighbour may not work in your traditional weatherboard home, and vice versa. It’s not about buying the most expensive insulation; it’s about choosing the exact type of insulation for your needs and budget. Let’s see how to do it.
Cracking the Code on Climate and R-Values
- Meaning of an R-Value?
As soon as you walk into the aisle where all the hardware is located, you will notice a big letter “R” along with a number on each and every package. This does not mean that you need to be baffled by that. It merely represents the efficiency level of any material in blocking the flow of heat into or out of your home. The bigger the number, the better it will protect you.
- The Right Number for Melbourne Homes
The weather in our immediate vicinity is totally crazy and unpredictable. With our brutal winters and blazing summers, we need some sort of basis. The normal R-rating for external walls in our area should be close to R2.5. Getting anything lower will leave you cold all winter, while anything higher is just money wasted on insulation that can’t fit in the wall cavities.
Assessing Your Wall Structure
- Open Studs for Easy Access
Are you currently renovating or building from scratch? If you are staring at bare timber studs, you have hit the absolute jackpot. This open access gives you complete freedom. You can easily push traditional glass wool or rock wool batts between the frames yourself over a single weekend. It is an incredibly cheap, fast, and highly satisfying project to finish.
- Closed Walls and the Retrofit Fix
If your painted plasterboard is already up, do not panic. You definitely do not need to tear down your beautiful rooms to fix the drafts. Instead, you can look into loose-fill blow-in cellulose. For this precise job, specialized insulation contractors in Melbourne will drill tiny, discreet holes into the walls and pump the material straight inside with zero structural mess.
Choosing the Right Material for Your Wallet
- Glass wool and Rockwool Batts
Glass wool is the highly affordable, traditional favourite that gets the job done cleanly. Rockwool costs a bit more upfront but is remarkably dense. If your home sits on a busy main road, near a loud school, or right along a noisy tram line, the incredible acoustic soundproofing from rock wool is worth every single extra dollar.
- Eco-Friendly Cellulose and Spray Foam
Cellulose is derived from shredded newspapers that have been processed for resistance to fire and insect damage. The material works marvellously in filling spaces around pipes and cables present within the walls. On the other hand, spray foam is the top-of-the-line solution and instantly fills up space with an air-tight seal.
Finalizing Your Project Path
- The Choice Between Do-It-Yourself and Hiring Professionals
Placing ordinary insulation rolls in an exposed wall frame is one of the most effective and easy-to-do methods to reduce labour expenses. However, when dealing with loose cellulose or spray chemical foams, do not use any machinery. Just one little error while using expanding foam may cause damage to your internal plasterboards.
Conclusion:
There are no quick fixes, as everything boils down to individual features of your house’s design and finances. Start off by selecting the appropriate R-value to tackle the constantly fluctuating climate in Victoria, and take into account the real conditions of your walls when choosing an insulation material that does not let cold air through and is not too expensive.
