With energy price hikes pretty much par for the course, finding ways to offset them is a top priority. We explore how insulation helps drive down your bills, and why spray foam is the best insulating material for heat overall…
What Is Insulation?
Insulation is a general term used to refer to a variety of products that prevent heat loss or gain, by providing a barrier between internal conditions, and the external environment.
The overall efficacy of insulation depends on a variety of different factors, including: age, type and overall quality of material.
The 4 Main Types of Insulation
Despite the diverse range of insulation materials on offer, their efficacy varies considerably. Let’s explore the most popular insulation methods available in greater detail:
- Fibreglass: Fibreglass may function effectively in the short-term, but over time, its overall performance is greatly reduced. This is due to the fact that it quickly sags and settles, leaving gaps between fibres that lead to additional air leaks. The fibrous nature of this material enables moisture to easily accumulate between layers, compromising thermal resistance in the process.
- Cellulose: Cellulose is simply shredded newspaper, and in terms of performance, leaves a lot to be desired. It also provides an excellent food source for rodents and pests, leading to all manner of additional problems, such as chewed wires and droppings.
- Rockwool: Also known as mineral wool, rock wool insulation is a far costlier choice, and is unable to insulate hard-to-reach places, such as around pipework and rafters.
- Rigid Boards: Rigid boards may offer increased structural support, but they still have to be cut to the appropriate size. This can be a laborious and time-consuming process. In matters of home improvements, time equals money; if you’re working with budget restrictions, then you’d be better off looking elsewhere.
