Insulation is the mechanism by which an object is enclosed or covered with a substance that acts as a barrier and reduces (or blocks) energy flow, primarily heat. -find out here It is used for the following purposes, in essence:
To decrease the loss of heat energy.
To keep objects from heating up nearby.
Some examples where insulation is usually used are given below:
Equipment-furnaces and ovens, fridges and freezers, water heaters, water pipes, etc.
On systems for commercial use.
Isolation can provide indoor comfort (by keeping your house cooler in the summer and colder in the winter) and energy conservation when done correctly.
It can be a challenge to decide and purchase the insulation that is best for your household. Any useful tips on how to buy the ideal insulation for your home are below.
- About whether to insulate. Identifying where the insulation will be mounted or used is the first thing to remember. A personal home inspection may be satisfactory, but it is always best to let the eligible individuals (such as your contractor) do the job.
Your household may need any or all of the following insulation, depending on your (or an expert’s) results:
Insulation wall / cavity wall. The insulation of the cavity wall prevents your house from being exposed to sudden outside changes in temperature. Studies show that heat loss can reach as much as 50 percent due to un-insulated walls, and cavity wall insulation may likely prevent 70 percent of this from occurring.
Insulation of loft / roof. Heat loss through the roof will hit as much as 25 percent because hot air increases. With proper attic or loft insulation, this can be significantly decreased.
Insulation duct / pipe. Leaky ducts or pipes may lead to an increase in the cost of your heating (or cooling). They can also burst (or freeze), so keeping them properly insulated is also critical.
Cylinders / storage tanks for water. In order to prevent them from being exposed to extreme cold or heat, hot water cylinders and cold water storage tanks often need to be insulated.
- About what to use. The following are typical insulating materials widely used in households:
Fiberglass / fibreglass mats / mineral fibre. The most popular and flexible type of insulating material that is manufactured from molten glass and spun into microfibers is fibreglass.
Fiberglass is usually pink or yellow in colour and comes in 3 forms:
Rolls-isolation blankets that may or may not have vapour barriers which prevent condensation from causing damage (such as mould) in cold areas.
Batts come in lengths ranging from 4 to 8 feet, similar to rolls.
This is loose insulation that can be ‘blown’ onto walls or ceilings.
About cellulose. Cellulose is another insulating agent that is widely used in households. It is a fibrous substance made of scrap or recycled paper that is shredded and treated with chemicals that will make it immune to fire and insects (like newsprint or cardboard). In the use of a machine, it is then applied (poured or blown-in) into place, either as loose-fill or wet-sprayed.
