1. Fiberglass Insulation
Fiberglass insulation is one of the most common and widely used insulation materials for freestanding garden rooms. It consists of fine glass fibers that trap air and create a barrier against heat transfer. Fiberglass insulation is easy to install, affordable, and offers good thermal insulation properties. However, proper protective gear must be worn during installation, as the glass fibers can be irritating to the skin and respiratory system.
2. Spray Foam Insulation
Spray foam insulation is a versatile option for insulating freestanding garden rooms. It is applied as a liquid and expands to form a solid foam that fills gaps and cracks. Spray foam insulation provides excellent thermal insulation and air sealing properties. It also acts as a moisture barrier, preventing condensation and moisture-related issues. However, professional installation is recommended for spray foam insulation, as it requires specialized equipment and expertise.
3. Cellulose Insulation
Cellulose insulation is an eco-friendly choice for insulating freestanding garden rooms. It is made from recycled paper and treated with fire-retardant chemicals. Cellulose insulation offers good thermal insulation properties and helps reduce noise transmission. It is typically blown into cavities or walls for proper installation. However, it may require professional installation to ensure even distribution and proper coverage.
4. Reflective Insulation
Reflective insulation is a unique type of insulation material that reflects heat radiation. It consists of a metallic foil layer that reflects radiant heat away from the interior space. Reflective insulation is often used in combination with other insulation materials for enhanced thermal performance. It is particularly effective in hot climates where reducing heat gain is a primary concern. Proper installation techniques, such as proper sealing and installation distance, are crucial for maximum effectiveness.
