Insulation is based on use of different materials. When it is thermal insulation for any building, there are materials that are low in thermal conductivity and hence they are known as excellent insulation materials. These materials are fiberglass, wool, rock wool, and polystyrene and these insulate buildings, but not as greatly as spray foam insulation or Polyurethane. This is the main reason they are selected for insulation purpose, as they protect the building.
Spray foam insulation
Insulation of a home or building is based on the thermal conductivity of gases. The gas has low thermal conductivity as its property and this way any plural component or single component insulation will be a good insulation material. The materials should have absence of convection through which the cold or hot air may not enter the insulated building from the environment. The spray foam insulation is one such material that is good investment for a home owner. The spray foam helps in sealing all the cracks and leaks of the buildings so that the air does not enter the building. Thus it will keep the energy bills low as the owner will need less power for heating or cooling the interior of the home. There are different equipment like the Gusmer Reactors and the hose and spray gun with which you can give proper insulation for a building.
Insulation and better home
Some benefits of this spray foam insulation:
- Saves the home from extra heating or cooling throughout the year
- Less noise within the house
- Cold spots and cool drafts are reduced to a great extent.
- The house gets better value for better protection and resale typically increases.
- Structural integrity improves due to less cracks and nicks.
- Less bugs, allergens and dampness inside the house.
- Built-in air barrier and moisture guard.
These features are present when the proper equipment like the Gusmer Reactors and quality materials are used for insulation.
Types of materials for insulation
There are inorganic materials and organic materials. They are:
- Fibrous materials – Glass wool and rock wool
- Cellular materials – Calcium silicate and Cellular glass
The organic ones are derived from petrochemicals. There are some that come from feed stock that can be renewable. These materials are polymers and these are cellular too. There are plants that contain fibers and when these are used for insulation materials, they are fibrous.
- Petrochemical materials (derived from oil or coal) – The materials are expanded polystyrene (EPS) OR Extruded polystyrene (XPS), Polyurethane (PUR) or Phenolic foam.
- Renewable materials (derived from plants or animals) – Cellulose, cork, hemp fiber, Wood fiber, Flax wool, cotton insulation and sheep’s wool.
- Some materials other than the above – Cellular glass, Vacuum Panels and aerogel.
Insulation for energy saving
The spray foam insulation has the highest rating among all the materials used for insulation. The other insulating materials may leave gaps in the walls but spray foam insulation reaches the area and then spreads, or cures, till it is dry. The result is that it covers the cracks and leaks with tight seals and hence the insulation will be complete. You will find your customers will not find any air movement through the insulated area and all the HAVC equipment will work better with less energy consumption. Resulting in helping customers save in energy cost at approximately 40% with proper insulation materials and the right kind of equipment.
