2. Cavity wall - Wikipedia

   en.wikipedia.org/wiki/Cavity_wall

   Incorrectly installed cavity wall insulation (CWI) causes water to seep into a property's walls, causing structural problems and damp patches that may also manifest into mould. In some cases, the damp and mould resulting from CWI can cause health problems or exacerbate existing conditions, particularly respiratory conditions.

3. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   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 ...

4. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   The buildings are being constructed using a systems build with a steel frame and various prefabricated components. The blue plastic on the central building is the vapour barrier for the thermal wall insulation before the exterior cladding has been fixed. Building insulation materials are building materials that form the thermal envelope of

5. Housewrap - Wikipedia

   en.wikipedia.org/wiki/Housewrap

   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 ...

6. Exterior insulation finishing system - Wikipedia

   en.wikipedia.org/wiki/Exterior_insulation...

   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.

7. Cellulose insulation - Wikipedia

   en.wikipedia.org/wiki/Cellulose_insulation

   This settling could leave gaps in a wall as the insulation compacts vertically, or it could leave space between a floor and the insulation beneath it. [5] A dense-pack option can be used to reduce settling and further minimize air gaps. Dense-pack places pressure on the cavity, and should be done by an experienced installer.
