What are the Different Types of Roof Insulation?

Maintaining a well-insulated house is crucial for homeowners living in a country like Canada. With regular extreme climate changes happening within a year, energy efficiency and keeping a healthy living environment need to be considered in all households. There are multiple areas inside houses and garages that can be installed with insulation materials. With the help from insulation contractors, it can be effectively determined which areas need to be installed with insulation materials. Some people do not realize that insulating their roofs can give multiple benefits to their houses. This article will focus more on the different types of insulation materials that may be used for the roofs of houses and garages.

The Main Purposes Of Roof Insulation

The roof of the house is one of the most essential parts of a house. It is the main protection against foreign materials from entering the house such as snow, rain, sun, air, and even dust. Roof insulation has multiple purposes for the houses and even adds support to the roofing material being used. By using the right type of insulation based on the material being used for the roofing of the house, it may help add strength to the overall roofing structure. However, the main use of roof insulation is to ensure that hot air may not escape or enter the house through the open spaces or gaps of the roofing material.

Insulation materials are used to seal these areas to ensure that nothing will be able to pass through them. Naturally, hot air is known to flow into areas where the temperature is relatively lower. This will clearly have an effect on the energy usage of the heating, ventilation, and air conditioning systems (HVAC) used in houses. Without proper insulation, HVAC systems will not be able to operate efficiently. Just like in summer when the temperature outside the house is much higher. During summer, hot air will try to flow into the house, which has a cooler environment.

If there is no insulation used on the roofing of the house, the air-conditioning system of the house will continuously run to ensure that the desired temperature set on the thermostat would be achieved. However, without anything stopping the hot air from entering the house, hot air pockets are continuously formed within the house which will make it hard for the HVAC system to reach the desired temperature. This will make the air-conditioning system continue functioning, which in turn would lead to more energy usage. This is why people say that installing proper insulation would generate savings on your energy bills.

Other Benefits Of Roof Insulation

As it can be seen, energy savings and added strength to the roofing of a house are the main purposes of installing insulation material on the roof. However, people should also consider the other benefits that they can also get with roof insulation. You may refer to the following list for these benefits:

  •       Roof insulation prevents water and moisture from entering the house through the roof. This is very important in relation to health reasons. The buildup of moisture and water can cause the formation of molds and mildews inside the house. Considering that the roofing and ceiling have various areas where molds and mildews can live but are not easily visible. Homeowners may find it too late when allergies and other sickness would affect the people living in their houses. Insulation will ensure that this problem will be avoided. However, people should also be careful with the type of insulation material they would use as molds and mildews are known to live in some types of insulation materials, especially if they are made from materials that are considered to be food for these molds and mildews.
  •       Dust is also a problem that may enter through roofs without insulation installed on them. Dust can also be the cause of health problems for people living in houses without proper roof insulation. Aside from allergies, dust can cause mild to severe health issues to certain people. For a house that has an attic built underneath the roofing, the homeowner may find it a nuisance that the attic would need to be cleaned regularly due to the buildup of dust inside it. This can be avoided by adding insulation on the roofing of the house.
  •       Insects and other pests may find holes or spaces on the roofing where they can easily go through to enter the house. This may cause some pest infestation inside attics, ceilings, or directly into the house or garage. Homeowners should ensure that pests will not be able to start living inside their houses and garages to avoid diseases and accidents from affecting their families. Proper roof insulation will effectively stop these pests from finding spaces that they would use to enter the property.

Different Types Of Roof Insulation

Knowing the importance of insulating the roofing of the house, people should also know which types of insulation materials would be effective in doing so. There are various types of insulating materials in the market, but there are only certain types that would be useful for roof insulation. Below are the most common roof insulation materials being used:

Wood Fiber Board

This is usually made from organic raw materials. The materials for these insulation boards may be composed of materials such as vegetable fibers mixed with fillers and binders, wood, or cane. To make this type of insulation material better in resisting moisture, it may be asphalt-impregnated or added with an asphalt coating. However, homeowners should make sure that the roof covering of their houses are compatible with asphalt-based coatings. If the roof covering is incompatible, then they should use uncoated insulation on the roof. The good thing with this type of insulation is that it is known to be durable, flexible, and can be easily cut and formed. These would make the installation faster. However, it may also deteriorate much faster when it gets in contact with moisture. Also, it has a poor resistance to fire.

Fiberglass Batt Blanket

This is the most common type of roof insulation being used for both roofs and attics. People prefer them due to their cheaper prices as compared to other types of insulation materials. It is usually made from fiberglass; however, there are kinds that use plastic fibers or mineral wool. This type of insulation material can easily be cut and shaped depending on the area that will be insulated. It is easy to install into areas such as ceiling joists and rafters. The insulation material is known to be moisture resistant. However, the backing material, which is usually made from paper, is known to be a good source of food for molds and mildews. It should be installed in a way that water and moisture will not be able to reach the backing material, so that molds and mildews will not be able to form and live on this area of the insulation material.

Structural Insulated Panels (SIPs)

This type of insulation is usually made from expanded polystyrene EPS or polyisocyanurate PIR. It can be installed in different areas of the house due to its availability in different thickness. The insulation material is made with prefabricated boards while having foam installed between the boards. This type of roof insulation became popular because it can be used as a replacement of a wood frame and can handle loads of 10-70 lbs/sq.ft. The material has a high thermal resistance which makes it energy efficient. However, the issue with SIPs is that it is vulnerable to water and moisture. They are basically not designed to get wet, which is why they should be installed carefully.

Spray Foam Insulation

Spray polyurethane foam (SPF) is one of the best types of roof insulation materials in the market. It is known to be one of the most durable and is able to effectively seal hard-to-reach areas that may have very small voids and cracks. The insulation material is applied by spraying the product on the surfaces. As the chemicals resin and isocyanate mix, the product eventually expands and hardens, creating a hard foam material. When applied properly, nothing can pass through without exerting a significant amount of force to break the insulation material. Even pests would need to claw their way through the material to be able to damage it. As the chemicals are being sprayed on the designated areas on the roofing, they are able to seep into very tiny spaces, which is very important as these are the areas that air and water will be able to pass through. The end result is an excellent insulation material for the roofing. However, the issue people may have with this type of insulation is that it is known to be toxic when inhaled or ingested, which is why a protective gear is required to be worn during the application process. To avoid mistakes or health issues from happening, it is highly advised that this type of roof insulation should only be installed by professional contractors.

Hire Professionals To Do The Job

Homeowners can definitely get a good value when they opt to install roof insulation in their houses. However, it is also important that this is installed properly to avoid wasting resources and also to avoid any accidents and any health problems during the installation process. To get the best results, homeowners should hire insulation contractors to do the job for them. This is important to note since these contractors have the necessary tools and techniques needed to efficiently go about with the installation of the roof insulation material.
