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.

Borrowing more than you can afford or paying late may negatively impact your financial status and ability to obtain credit. Credit subject to status. Ts&Cs and late fees apply.
