07 May An ultimate guide on the 5 most common thermal insulation materials
Today, the marketplace is full of ridiculous products; hence it is straightforward to be blinded by low quality and cheap thermal insulation materials. There some elements which have been in the market for quite some time and they are of high quality. However, Advanced Insulation and Fabrications who are commercial installation specials have in-depth research on the type of materials you need to purchase depending on your requirement or situation.
Here an ultimate guide on the best common thermal insulation materials worth investing for any small to medium-sized project.
Production of fibreglass makes it the most common thermal insulation materials. Its manufacture involves efficiently plaiting fine strands of glass into insulation materials hence enabling minimization of heat transfer. However, every insulation material has its downfalls, and fibreglass is no exception.
Its danger occurs when handling since its components (glass powder, woven silicon, and glass shards) can impact your skin, lungs, and eyes if you don’t wear highly protective gear. Fibreglass has R-values ranging from R-2.9 to R-3.8 per inch hence making it non-flammable.
2. Mineral wool
There are three different kinds of insulation when it comes to mineral wool. First, glass wool is made of recycled glass. Thus, its qualities are close to those of fibreglass. Second, rock wool is manufactured from basalt. Lastly, slag wool is made of slag generated from steel mills.
In cases of extreme heat usage, mineral wool is not the best because they are not fire-resistant due to lack of enough additives. When broad insulating areas, consider using mineral wool since it is not inflammable. It has R-value ranging from R-2.8 to R-3.5.
Cellulose is a form of insulation that is renowned for its eco-friendly nature. It is produced loosely hence consists of various materials such as paper and recycled cardboard. According to a recent study, cellulose can reduce fire perils because it has an R-value between R-3.1 and R-3.7. Besides, it has les oxygen in it due to its compactness.
When it comes to the best insulation for fire-resistant, cellulose holds the budge making it more environmentally friendly. However, one of its merits is that is causes allergies to dust allergic people.
4. Polyurethane foam
Polyurethane foam is a brilliant form of insulation, although not the best. It ensures the reduction of damages of the ozone layer since it uses non-chlorofluorocarbon (CFC) gas, which makes it’s a blowing agent. Polyurethane foam materials are light to handle hence has an R-value of approximately R-6.3 per inch of breadth. It works better when sprayed on areas with no insulation. Moreover, it is fire resistant, thus being an added advantage.
Polystyrene is an outstanding temperature, and sound insulation material since its thermoplastic foam is usually waterproof. It is manufactured in two types, that is, expanded (EPS) and extruded (XEPS). XEPS has an R-value of R-5.5 while EPS has R-4, thus making the two types diverse in terms of cost and ratings. It has a smooth surface; hence you will not undertake many insulation procedures.
When using the material, ensure that you use Hexabromocyclododecane (HBCD), which is a flame-retardant chemical because polystyrene is highly flammable.
Consequently, safety is the key and cannot be traded for anything. Always ensure you are in the right gear to reduce the risk of health damages. Always wear face masks, gloves, and eye protection before handling any thermo insulation materials.
