    Our Insulation Process

    Sydney is home to warm summers and mild winters, which means that insulation is an important component to your home no matter what time of year it is.

    When you call Cosy Insulation for residential insulation installation, one of our professionals will meet with you at your home to determine your insulation needs.

    We will measure the areas that you need insulated and figure out what type of insulation will work best. Some areas will need different insulation ratings than others, and our pros can help you figure out what you need. For example, roof insulation may need to be rated higher than insulation in inner walls.

    Once we know what type of insulation you need and how much you need, our professional installation crew can get it done quickly and efficiently.

    Our insulation services also include roof insulation, which ensures that your home has no areas where your cooled air can sneak out on a hot day.

    Removal of Insulation


    Over time, insulation can become contaminated with mold, mildew, and other harmful substances, leading to a decrease in indoor air quality. Additionally, outdated or damaged insulation can cause energy inefficiencies, resulting in higher utility bills. Due to these reasons, it is important to have a professional insulation removal service handle the process to ensure that it is done safely and effectively. Our team of experts is equipped with the knowledge and tools necessary to remove your old insulation and replace it with new, energy-efficient insulation. Let us help you improve the health and efficiency of your home.

    In order to expel the heat and moisture from your roof space, it is essential that fresh, external air replaces the super heated air removed by your Edmonds vent. This can be achieved by installing at least FOUR under eave vents per ventilator. Ideally, inlet vents are set into eaves which face the prevailing winds. For the best results, and improved home comfort, also install a Whirly Mate in the ceiling of your home to allow the trapped hot air to escape from inside your home at the end of the day, allowing cooler, fresh air to enter your home.
