INSULATION

FAQ

Insulation is a material used to reduce heat loss or gain. It helps maintain a comfortable temperature in your home, improving energy efficiency and reducing utility bills. Choosing the right insulation depends on factors like climate, budget, and the area of application.

Insulation materials are selected based on thermal resistance, moisture resistance, and fire safety. Consider the R-value, which measures thermal resistance. Higher R-values offer better insulation. Also, assess the material's compatibility with your building structure and environmental impact.

Insulation types include fiberglass, foam board, and cellulose. Fiberglass is cost-effective and easy to install. Foam board provides excellent thermal resistance for walls and roofs. Cellulose, made from recycled paper, offers an eco-friendly option but may require professional installation.

Insulation: 3 things to consider before buying

When selecting insulation, R-value is a crucial factor. It measures how well insulation resists heat flow, so the higher the R-value, the better it insulates. Consider your climate and where you'll install the insulation. For example, lofts in colder regions may require insulation with a higher R-value compared to walls in milder climates. We recommend checking local building codes or consulting a professional to determine the appropriate R-value for your project.

Insulation comes in various materials, including fibreglass, foam board, and cellulose. Each has its pros and cons. Fibreglass is popular due to its affordability and ease of installation but can irritate skin and lungs if not handled properly. Foam board provides excellent thermal resistance but may be more expensive. Cellulose, made from recycled paper, is eco-friendly and offers good soundproofing but may settle over time. Consider factors like budget, environmental impact, and specific needs when choosing the material.

Moisture can significantly affect insulation's performance and longevity. When buying insulation for areas prone to dampness or humidity, such as basements or bathrooms, look for products specifically designed to resist moisture. Closed-cell spray foam is an excellent option as it acts as a moisture barrier while providing high thermal resistance. Alternatively, ensure proper ventilation and vapour barriers are in place to protect other types of insulation from moisture damage.
