Once the framework of your new home build is erected, you need to decide on what insulation will be the best solution for your new residence before the exterior materials can be assembled. The great thing about a custom home build is that you not only have the final say regarding the insulation supplies to be employed but you also get to choose where you want them installed.
With that in mind, most homeowners tend to focus solely on either the interior or the exterior part of the walls but not both. However, this could lead to some challenges down the road. To ensure that you are making the right decisions, here are some answers to questions that you may have regarding wall insulation for your custom build.
What Is R-value?
"R-value" is a term you will constantly hear when discussing residential insulation. It simply means the overall resistance a material offers against the flow of heat. Hence, it is a term that connotes the thermal efficiency of the insulation products you are considering. To measure this value, the weight, type and thickness of the insulation are taken into account.
It is worth noting that the R-value that would be ideal for your house is dependent on your location. Since some parts of Australia experience more severe radiant heat than others, the professionals providing you with wall insulation services are best placed to guide your decision.
Should you insulate both your interior and exterior walls?
Although insulating the interior of the walls does provide you with relief against thermal gain, you can enjoy additional benefits when you invest in insulating the exterior parts too. If you reside in a location that is vulnerable to extreme temperature drops during the winters, insulating the exterior part of the walls can help decrease the amount of cold that seeps into your home. As a result, you will not be entirely reliant on artificial heating once the winter months roll around.
Insulating the exterior of your walls also comes with the benefit of minimising the formation of condensation on these surfaces, which can prolong the lifespan of your window and door frames, not to mention the reduced risk of water damage and mould infestations. Therefore, while the insulation on your exterior walls can be viewed as a bonus addition, it can prove invaluable for the long term.
When it comes to the types of insulation you can purchase for your home, you have a multitude of solutions to consider. Polyurethane foam is a top solution for insulating the interior of the walls since it has low density while providing high thermal insulation. Alternately, fibreglass batts are perfect for the exterior of your walls, as they are pre-treated for pest resistance.
