If you plan to convert your garage into a living area, whether to entertain your friends or to use as a man cave or even a spare bedroom, it is imperative to insulate the space. Without insulation, your garage will be vulnerable to both thermal loss and gain, which can make it an uncomfortable space to be in during inclement weather. Once you choose to protect this space from heat gain and drafts, you will find residential insulation comes in a myriad of options. Moreover, you have to select insulation based on what will be best for your needs rather than picking the cheapest material available. If you are deliberating on insulating your garage, below are a few of the materials that you can consider.


Undeniably, fibreglass is the most popular material in the market and is one of the readily available options when you are in search of residential insulation. This type of insulation comes in batts that have been pre-cut and will be attached directly onto the walls you are insulation. Additionally, you could also utilise fibreglass in loose-fill form since this is best suited to insulate crevices that the batts cannot cover properly. If you are not planning to cover the interior walls with the insulation, you should opt for the encapsulated variety so that the residential insulation is not exposed.


This type of residential insulation is growing in popularity for a couple of reasons. For starters, cellulose is an eco-conscious type of residential insulation. Since the material comprises recycled newspaper that has been pre-treated to make it fire-retardant. Secondly, the cellulose residential insulation is in a loose-fill form that is aerated to grow in size once it is installed. Since the cellulose puffs up, it can be used is spaces both large and small since it only gets to fill size once it is already applied where it is needed.

Rigid foam

As the name implies, this type of residential insulation is a foam-like substance that is hard to the touch. The materials that are used to manufacture rigid foam insulation are typically expanded polystyrene, polyisocyanurate and extruded polystyrene. Rigid foam insulation is typically higher priced than conventional forms of insulation but this is not without reason. The R-value of rigid foam insulation is high, and the degree of insulation that it will provide will depend on the thickness of the sheets. If your garage door has thin walls, then rigid foam insulation will be the best choice for your living space.
