The Three Best Materials For Thermal Insulation

The thermal insulation is one of the most important factors for achieving a high level of energy efficiency and the installation of these materials became the standard part of the house building process. Any builder or any professional house building agency would stress the importance of energy efficiency and that the thermal insulation should be included in the process of building your house, especially if we want to keep our electricity and heating bills at the minimum.

Different materials show fantastic results in keeping your house warm and for this time, we have prepared the best three ones that you should use.


Among all materials, fiberglass is the one with the best characteristics when it comes to making your house warm. Due to its structure that is characterized by the micro strands of glass, fiberglass showed the best results when it comes to the thermal insulation.

These micro-glass strands are mixed with woven silicon, glass powder and really small pieces of glass to create the medium that effectively fights the cold during the winter and heat during the summer. However, the improper preparation and installation of this material may lead to serious lung injuries, eye irritation and skin damage.

However, if installed properly, the material is resistant to the flame and offers R values from 2.9 to 3.8 per inch, and makes your home much more energy-efficient.

Mineral wool

Although mineral wool actually encompasses more materials (glass, rock, mineral and slag wool), the most used type of this material for thermal insulation is the mineral wool. It consists of the molten glass, stone, or industrial waste that is structured in the form of the fibers, similar to the fiberglass.

However, the mineral wool is flammable, though the rock, glass and slag types are not due to the additional extracts that are added into the final structure. Still, the mineral wool can provide fantastic results when it comes to achieving the optimal energy efficiency and it is widely used as an insulation material. Especially in the areas where the fire is not present!

Polyurethane foam

This is a spray-like foam that uses non-chlorofluorocarbon gas as the main ingredient, which allows this material to be applied in the gas-like state. Being lightweight, the material is perfect for handling and on top of all, it will not burn, even at the high temperatures, but rather melt.

Unlike fiberglass, this foam is much cheaper but has lower R-value of only 3.6. Polyurethane foam can be used in the areas where no insulation exists at all and that is why it has been used widely as the replacing material for the fiberglass, which is the best thermal insulator.

What should you use?

This is a question of personal preferences. If you want to use the fiberglass, have in mind that is great, but requires extreme caution when working with it, as it can damage your health permanently.

On the other hand, the mineral wool and polyurethane foam are bit cheaper but do not offer resistance to fire, as well as a high level of eco-friendly rating. Choose what you can afford, just make sure to handle the materials safely and properly.
