Insulation material concept

Currently on the market there are many cheap and popular insulation materials. Many of these products have been around for a long time. Each of these insulation has its own ups and downs. Therefore, when deciding which insulation to use, you should be sure which one will work best in your condition. We've looked at differences like R-value, price, environmental impact, flammability, sound insulation, and more below.

1. Insulation materials from fiberglass (glass wool):
Fiberglass is the most common insulation used in modern times. Because it is composed of many very thin glass fibers arranged into a porous texture similar to wool and is bonded to bind the fibers together flexibly, the product has thermal, soundproof, and fireproof properties. good, environmentally durable, not corroded by chemicals, fiberglass can minimize heat transfer. The main disadvantage of fiberglass is skin irritation to NEW people when handling it. However, when proper safety equipment is used, fiberglass installations can be performed without incident.

2. Insulation material from rockwool fiber (rock wool):
Mineral wool insulation actually refers to several different types of insulation. First, it can refer to glass wool which is fiberglass manufactured from recycled glass. Second, it may refer to rock wool, a type of insulation made from basalt. Finally, it may refer to wool slag produced from slag from steel mills. Most mineral wool in Vietnam is actually made from rock wool.
3. Polyurethane foam insulation materials:
Although not the most abundant insulation, polyurethane foam is an excellent form of insulation. Today, polyurethane foam uses chlorofluorocarbon (CFC)-free gas for use as the blowing agent. This helps reduce the amount of damage to the ozone layer. They are relatively light, weighing about 2 pounds/cubic foot (2 lb/ft^3). They have an R value of approximately R-6.3 per inch of thickness. There are also low density foams that can be sprayed into areas without insulation. These types of polyurethane insulation tend to have an R-3.6 rating per inch of thickness. Another advantage of this type of insulation is its resistance to fire.
4. XPS foam insulation:
Polystyrene is a waterproof thermoplastic foam that is an excellent sound and heat insulator. It comes in two types, expanded (EPS) and extruded (XPS) also known as foam. The two differ in performance and cost ratings. The more expensive XEPS has an R value of R-5.5 while the EPS is R-4. Polystyrene insulation has a unique smooth surface that no other insulation has.
