Multi-read content how to insulate interior walls in an existing house

A large proportion of homes in Australia are poorly insulated. Unfortunately, this means that many Australians experience uncomfortable indoor temperatures all year round and pay more for their electricity bills. This is a particular problem in older homes where wall insulation is missing or has lost its effectiveness. Without proper insulation, you can lose up to 25% of your home’s heat in the winter and gain 25% more in the summer..

If your home is uncomfortably cold in the winter, unbearably hot in the summer, and hard to heat or cool, you probably need to replace the insulation in your walls. It’s one of the best ways to effectively regulate your temperature, lower your electricity bills, and help the environment. Installing insulation in new homes during the construction phase is simple and effective, but insulation can also be retrofitted in existing homes. If you think your wall insulation is missing or not working properly, be extra careful. Below, we cover some of the most important factors you need to know to start upgrading your home with insulation.

Why change the insulation of my walls?

Proper wall insulation will make a tangible difference to the temperature inside your home. Insulated walls are built to last for many years. However, insulation with a lifespan of 10 years or more may need to be checked for damage, mold or vermin. Over time, the R-value of insulation products can decrease, which means they become less effective at resisting heat flow. This is usually due to compression, moisture or movement creating gaps in the insulation. Rotten or damaged insulation must be completely removed and new insulation installed in the area.

What is the best wall insulation?

From fiberglass sticks and blown cellulose to spray foam and foil-backed insulation, there are many types of insulation. Below we review a fewmost popular productsused in wall renovation applications.

  1. Insulation mattress
  2. Insulation mattress
  3. is pre-cut bulk insulation for mounting between wall braces. They are usually made from glass wool (aka fiberglass), polyester, and rock wool. Electric batons are generally inexpensive, effective, and highly fire resistant. Dedicated sound kit
  4. also provides noise reduction effects. If you live in a home that doesn’t have insulated walls, your best option is to remove the plaster and install insulation board in the recesses.
  5. Cellulose blows
  6. Cellulose insulation blowing requires more installation effort than stick insulation because training is required before using the blower. Since cellulose insulation is made from raw paper, it has a lower fire resistance rating. Overall this product is quite effective but has a short lifespan and can be blown away leaving gaps between the insulation. The actual engineering required for effective blowing insulation is also often overlooked. If the insulation is blown in with bracing and compression material, it will be significantly less effective!
  7. spray foam
  8. Spray foam is more expensive than other options and must be installed by a professional. In general, spray foam has a longer life, is permanent, and does not sag or lose its R-value over time. Spray foam comes in two forms; collapsible cell structure. Cellular foam has air voids inside the material and takes up more space per weight. As the foam expands, it fills air spaces and prevents drafts. Closed-cell foam is more common and denser, so it has a higher R-value. Retrofitting existing walls with foam insulation is expensive, so we generally recommend installing fiberglass insulation boards.

Bats vs. Blown-In

Let’s see how stacked insulation boards hold up against blown insulation in several categories.

  1. When to install
  2. The perfect opportunity to install wall insulation panels arises during a major renovation or extension project with brick veneer or siding walls. When the wall covering is not removed, blown insulation can be used and small particles of insulation will fit into the cavity space. However, it is often an expensive way to insulate your walls.
  3. Easy to install
  4. Batt insulation can be installed as a DIY project or by a professional. The bats are easy to handle and are pre-cut to fit between the wall slats of most Australian homes. For hard-to-reach or hard-to-reach spaces, the stick can be easily cut into the correct shape. This is the most effective way to insulate your home. Blown-in insulation usually requires professional installation using specialized equipment. The recess can be accessed either by lifting the brick above the niche or by making a small hole on the outside of the wall.
  5. Assess
  6. In Australia, batts are a cost-effective alternative to blown-in insulation. Alternatively, mattresses can be installed as a DIY project, which can help cut costs even further.
  7. Effective
  8. The batts provide excellent resistance to heat flow and also provide acoustic benefits. They come in a variety of R-values ​​to meet your needs and budget. Insulation blowing is also very effective, but care must be taken during installation so that particles are not blown away. Also, if any moisture collected by the insulation blows away as it enters the recess, performance will suffer.
  9. Longevity
  10. Insulation whips are much more durable and long lasting than blowing in insulation. Flats are more likely to stay in place and continue to provide heat resistance long after the blown insulation has stopped working. Over time, blown insulation can settle or move down into the cavity, leaving air pockets at the top. These airbags allow significant heat gain and loss. This is rarely the case in bare spaces, but for walls blown insulation poses a major drawback.
  11. Fire classification
  12. In general, better insulation is better when it comes to fire safety. Blown-in cellulose insulation is made from raw paper and is therefore much less fire resistant. glass wool and
  13. Rock wool mattress
  14. has exceptionally high fire resistance and will not produce harmful fumes in a fire.

How to properly renovate wall insulation

Ultimately, the mattresses offer better value for money, exceptional durability and long-lasting performance. If you’ve decided to upgrade your walls with insulation during a major renovation, batts are the way to go.

In your renovation project where the recesses are exposed, the insulating bars are pressed between the spacers and can be fixed in place. It is important that the mats are not compressed and that there are no gaps left during the installation process. Insulation should be fashioned and installed behind all electrical and plumbing work and, if required, bars can be cut to size. A good rule of thumb is to increase your cup size by 10mm to ensure a perfect fit. Any cut can be used to fill gaps around windows and doors.

If you are going to install it yourself, be sure to read itDIY tutorialto ensure the best results. Improperly installed insulation will be less effective. Also make sure that you use the necessary safety equipment. Gloves, goggles and long-sleeved shirts should be used.
