Insulation is an absolute necessity in many parts of the world, and a highly desirable product everywhere else. Building insulation is designed and manufactured to improve the comfort of the residents inside, and improve the efficiency of the heating and cooling processes used within the building. While the vast majority of building insulation is designed and installed for thermal purposes, there is also a market for other types of insulation, including thermal insulation, fire insulation, and impact insulation. There are a number of popular insulation materials on the marketplace for builders and consumers to choose from, from simple natural materials through to high-tech modern formulations.

Thermal insulation materials are by far the most common kinds of insulation products found in modern homes, especially in colder climates that require extensive heating throughout most of the year. Some of the most popular insulation materials that are used to create thermal comfort include glass wool, rock wool, cellulose, vermiculite, earth or soil, and polystyrene. Some of the factors that influence the choice of thermal insulation materials include their cost, availability, quality of construction, and effectiveness for particular climate environments. The effectiveness of thermal materials is often evaluated within a particular scale, known as its R-value. Whether people live in cold or hot climates has by far the biggest effect on the choice of thermal materials, as some products are designed especially for cold climates and others for warm ones.

There are two basic kinds of building insulation that are commonly used; reflective insulation and bulk insulation. While the majority of buildings use a combination of both of these materials, it is always a good idea to match specific materials to the form of heat transfer that is relevant within your building and your home – radiation, conduction, or convection. Some of the most popular types of thermal building insulation include spray polyurethane foam, concrete forms, structured panels, fibreglass blankets, wood fibre, cellulose fill, and cotton batts. For anyone planning to install insulation in their home, it is always a good idea to research a variety of these materials before making your final decision.
