The borates in cellulose insulation provide added control against mold. Installations have shown that even several months of water saturation and improper installation did not result in mold. [10] It is a common misconception that the mere presence of crude borates in cellulose insulation provides pest control properties to the product.
Housewrap functions as a weather-resistant barrier, preventing rain or other forms of moisture from getting into the wall assembly while allowing water vapor to pass to the exterior. If moisture from either direction is allowed to build up within stud or cavity walls, mold and rot can set in and fiberglass or cellulose insulation will lose its ...
Cellulose insulation is environmentally preferable (80% recycled newspaper) and safe. It has a high recycled content and less risk to the installer than fiberglass (loose fill or batts). [27] R-Value 3.4 – 3.8 (RSI-0.60 – 0.67) per inch (imperial units) Loose fill insulation fills the wall cavity better than batts.
If the renovation is of a smaller nature, the renovation directive applies. Examples of renovation are post-insulation of a cavity wall and post-insulation of a sloping roof against the roof boarding or under the tiles. Note that every renovation must meet the minimum Rc value of 1.3 W/(m 2 ⋅K). If the current insulation has a higher ...
Exterior insulation and finish system (EIFS) is a general class of non-load bearing building cladding systems that provides exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system. EIFS has been in use since the 1960s in North America and was first used on masonry buildings.
A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction, refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials. [1] [2]
