Insulation keeps you comfortable throughout the year. You can use different types of insulation, namely thermal, acoustic, fire, and impact insulation. When planning roof insulation for your home in Brisbane, you will come across values, such as R1.5 and R4.1. Understanding what these values mean can help you choose the right material and type of insulation for your home.


The R-value represents a material’s thermal resistance. To compute for this value, experts divide a material’s thickness by its thermal conductivity, or its ability to produce heat. The higher the value, the more effective the insulation is. Other factors, however, may affect the efficiency of your roof insulation in your Brisbane property. Depending on the R-value alone isn’t enough. You should also consider the material and the way you installed it. For instance, insulation installed between studs may decrease heat loss but wouldn’t eliminate it because of air leakage.

Types of Insulation

  • Thermal Insulation—Maintaining an acceptable temperature at home or in an office uses a huge amount of energy. In fact, families and businesses spend a huge portion of their budget for this. To save on energy costs, homeowners and companies install thermal insulation. With this feature, your home will have less temperature gradient. This leads to a comfortable temperature inside your home, even if the temperature outside is extremely hot or cold.
  • Acoustic Insulation – Families living on a busy street or within a noisy neighbourhood will benefit from acoustic insulation. It controls the sound coming in your home so you can rest peacefully. You can also use this to manage noise between rooms. If your home office is beside your kid’s room, you can install this between the rooms to decrease distractions.

Kinds of Insulation Materials

  • Batts and Rolls – These are popular materials used for thermal roof insulation on Brisbane homes. You’ll find batts in R-values between R2.5 and R4.1.
  • Concrete Block Insulation – For unfinished homes, experts install these outside the wall. For existing homes, experts install this inside the wall.
  • Foam Board or Rigid Foam – This type of insulation is composed of polyisocyanurate, polystyrene, and polyurethane. Experts install this in ceilings, floors, unfinished walls, and unvented roofs with low slope.
