Fiberglass (37)

Install fibreglass insulation for comfortable interiors. It has a low thermal conductivity to protect rooms from external temperatures, and works with other insulation such as membranes. The acoustic properties help protect privacy, and supporting acoustic insulation supplies are free of harmful chemicals. These building insulation supplies are durable and easy to shape. They are resistant to water, corrosion, and fire. Their surfaces also resist the growth of mould. Choose from blanket format or pre-cut pieces for convenient installation.
Fibreglass insulation increases energy efficiency by controlling loss of heat and keeping out the cold. Its plastic construction with tiny glass filaments and pure sand reinforcements increases the resistance to fire. Fibreglass is also resistant to mould and mildew. The insulation is easy to install, and some comes in blanket-like rolls suitable for long unobstructed spaces like attic joists. Pre-cut batts are easy to cut to size and install; their foam-like design enables them to friction fit between studs. Blown-in or loose designs are also suitable for irregular spaces, such as floors, attics, or walls. Other options include rigid boards to use between joists above basements or crawl spaces and ducts.

Flexible and soft fibreglass insulation is suitable for stapling between joists in the floor or rolling out between rafters in ceilings and attics. Options with high R-values (resistance values) have superior capabilities to restrict heat flow and are suitable for different applications. Insulation blankets also come in varying thicknesses and may have acoustic properties to reduce noise and fill empty spaces along walls, floors, and ceilings. Various building insulation products are free from potentially harmful substances such as formaldehyde, chlorofluorocarbon (CFCs), and brominated flame retardants, making them safe for home and commercial use. Eco-friendly insulation is made of recycled fibreglass and plastic materials to minimize environmental impact.

Foundation blankets insulate concrete basement floors and walls. They provide a continuous vapour barrier that also reduces air leaks around sills and header plates. Fibreglass insulation is available in packs of various sizes for renovation and new construction projects. Rona’s calculator tool can help estimate how much insulation to use for various projects. Consider installing rigid insulation such as those made from extruded polyethylene for use indoors or outdoors to act as vapour barriers in small insulation jobs and for packaging. Other construction supplies are also available including joists, hinges, and beams.
