Insulation Materials: A Brief Guide Insulation  InsulationPost Reply
Insulating homes, offices, industries and other work or living spaces can save up a huge amount of money for domestic users & small to medium sized enterprises. It can benefit corporations and companies in terms of saving energy and costs too. Basically, Insulation materials are used to provide a blanket or shield around the building or structure that prevents conductive and convective transfer of heat, as a result, the covered area requires less electricity (gas, fuel & other means of energy) to heat up or cool down the insulated space. There are various types of insulation materials introduced by loft and roof insulation suppliers for saving energy, but are installed depending on the client’s customized demands. Although it is advised to get the insulation installed by a professional company, but in case of hiring a private labour, make sure to acquire a complete installation-guide from the manufacturer for the specific type of insulation material that you intend to install at your homes or workplaces.

Some of the most common types of insulation materials are widely available by in local markets and they all come with some pros and cons. For instance, blankets (batts and rolls) of Fiberglass or Mineral wool are relatively inexpensive, but are only suitable for studs and joist spacing that are relatively free from any hindrance. Concrete Blocks are placed on the inside of already existing buildings or on the outside of new constructions to increase R-value of walls. It requires specialized skills (or professional’s help) for installations. Foam boards or rigid foams can be installed in unfinished walls, roofs and ceilings and provide high insulating value for relatively little thickness. These rigid foams would not resist fire, therefore, these should be covered by gypsum board for fire safety when installed inside, and need to be covered by weatherproof facing if these are installed on the outer side of the building. Insulating Concrete Form (ICF) creates high thermal resistance is installed as part of the building structure only while the construction is taking place. Loose-fill or blown-in (fiber glass, cellulose or mineral wool) are blown into wall cavities, unfinished attic floors, irregularly shaped areas, or other hard-to-reach places, but require a special equipment for installation; insulating foam (sprayed foam) is sprayed, injected or poured in wall cavities and irregularly shaped areas or around obstructions but some foaming agents (such as CFCs – chlorofluorocarbons and HCFCs – hydro chlorofluorocarbons) are known to damage the ozone layer. Reflective system uses foil-faced kraft paper, cardboard, plastic film or polyethylene bubbles to prevent downward heat flow by reflecting heat back into the atmosphere, therefore, could be inappropriate for regions that have higher temperatures; Structural Insulated Panels (SIPs) are assembled or fitted together by construction workers to form walls and ceilings. The SIPs take less time to build and provide uniform and superior insulation compared to the traditional construction methods, but requires additional means for fire safety.
