Loft insulation is typically made up of high-rated insulation materials and finishes. Exterior walls are always insulated to protect the building from cold weather. The question now is if you can use loft insulation inside your wall for their benefits.<\/p>\n\n\n\n
For most cases, it is not recommended to use loft insulation finishes\/materials for your walls. There\u2019s a reason why loft insulation uses highly rated insulation to prevent heat from escaping from your home since most of it runs through a loft. It would be costly and impractical to use the same insulation type for your exterior and interior walls.<\/strong><\/p>\n\n\n\n Read on as we\u2019ll be going into insulation in general and the various pros and cons of using loft insulation in your walls.<\/p>\n\n\n\n To put it simply, insulation rating is used to describe how well an object can prevent heat flow transmission. This is a good thing because we don\u2019t want the heat to escape from our homes during winter.<\/p>\n\n\n\n Insulation rating is simply derived from how well a material can deter the flow of heat through it. You may notice that some requirements, such as an insulation rating of R60, can\u2019t be achieved through one finish. Multiple insulations are needed, and their ratings are added together to reach this number.<\/p>\n\n\n\n If there is one particular benefit of using loft insulation for your walls is that it will indeed significantly reduce thermal bridging from happening. Thermal bridging is a term used to describe how heat tends to flow and concentrate into a path of least resistance. This is why heat tends to go towards your studs, joists, and other parts of your home that aren\u2019t fully encapsulated by insulation.<\/p>\n\n\n\n A situation where you can use loft insulation on your walls would be for walls near a boiler, for example. It wouldn\u2019t hurt, and it wouldn\u2019t be too costly to put up loft insulation on a section of a wall that the boiler is attached to. Loft insulation tends to have a very high fire-resistance value due to its density and material. It is also great for protecting older studs from deteriorating because of the heat from a boiler.<\/p>\n\n\n\n We\u2019ll now be going into the cons of using loft insulation in your walls. We\u2019ll be coming from a practical perspective for the points we listed below.<\/p>\n\n\n\n The insulation used for lofts is explicitly designed for it. A home can lose up to 25% of its heat through its attic. Walls don\u2019t need as much insulation because not that much heat goes towards them.<\/p>\n\n\n\n Loft insulation is highly thick and often quite challenging to install than other insulation finishes found inside a house. Using loft insulation in your walls will be extremely expensive, compared to the costs of installing regular insulation, and you wouldn\u2019t be getting more value to justify the higher prices.<\/p>\n\n\n\n As we mentioned earlier, installing loft insulation on walls would be challenging and won\u2019t have many additional benefits. It also doesn\u2019t work well because, most likely, you have utilities running through those walls that you may need to access. Having loft insulation like fill or blown-in will make it much more difficult for them to be accessed.<\/p>\n\n\n\n There you have it, loft insulation doesn\u2019t work well or isn\u2019t worth it for general wall insulation needs. These are one of the scenarios in which less is more to get the same results.<\/p>\n\n\n\n
