Climate changes can cause uncomfortable living conditions. It is a known fact that hot air tends to move from a hot place into a colder area. With proper insulation, a barrier keeps hot air from leaking out during winter, while during summertime; hot air is blocked from seeping into the building. This is important as bills increase with the use of heating and cooling systems. With proper insulation, you may not need to use such systems since heat flow is controlled. One of the best locations to put insulation is in the roofing of the building. In this article, you will get to see more information about roof insulation and some of its common forms.
Forms of roof insulation
- This is the most common type of insulator.
- Facings are attached on some to act as barrier for vapor and air.
- Suited to be installed in wide and large areas.
- It can easily be cut for smaller areas.
- Material can be made from minerals, plastic fibers, natural fibers, or fiberglass.
- Can be installed on floors, ceilings, and unfinished walls by fitting it between joints, studs, and beams.
- The insulation material is a foam board that can be placed inside or outside of a wall.
- This requires specialized skills from experts to install on unfinished and new walls.
- This is added to increase the wall R-value (the measure for which how well an insulator can reduce the flow of heat).
- Can be made from materials like polystyrene, polyisocyanurate, or polyurethane.
- Useable in any part of the home.
- Used on exterior wall sheathings, interior sheathing for basement walls and exterior wall sheathing.
- Provides good thermal resistance and reduce heat conduction.
- Compared to other insulation forms, this works by reflecting radiant heat.
- Usually installed in attics to reduce heat during the summer.
- Aluminum foil is used as radiant barriers.
- This is not a good option for areas that have cool climate all throughout the year.
- Composed of either fiberglass or mineral wool material.
- Used primarily to insulate air ducts.
- This is a good option for areas affected by high temperatures.
- Has a thickness range of 1” to 2.5”.
Loose-fill and blown-in
- Composed of small particles of mineral wool, cellulose, and fiberglass.
- The insulation material comes in small sizes which are blown into the areas with small spaces like wall cavities, or unfinished attic floors.
- A liquid foam insulation that can fill into very small cavities.
- The process involves applying a mix of chemicals on to surfaces like ceilings, walls, basements, and other areas of the house or office that have cavities such as cracks or gaps.
- When sprayed on to the surface, the mixture of the chemicals is released as foam which seals the cavities. Installation is done by spraying the mixture of 2 parts: isocyanate and resin.
- The foam expands and hardens after some time.
- There are 2 types:
Open Cell Spray Foam
- It is a soft low-density material.
- Made for interior application like basements, attics, underside of roof decks, or wall cavities.
- Allows bi-directional drying.
- Allows moisture permeability for moisture management.
Closed Cell Spray Foam
- It is a rigid medium-density material.
- Suitable for both interior and exterior application.
- Improves the impact resistance of the wall.
- Strong protection against water damage.
Professional installation of insulation materials
Though there are processes that can be done by normal people, it is still highly recommended that you should be in contact with the experts regarding roof insulation. Before purchasing materials or choosing a form of insulation, Installation or application process can become complicated depending on the location and size. Furthermore, having a professional team proceed with the project implementation, you are assured that they are equipped with the much needed skills and tools.
With precision and accuracy, the process of applying can be done by anyone as long as the person has the proper tools and equipment. However, one must also be familiar with the steps and processes and must apply the product with precision and accuracy to avoid ruining or wasting the product. In addition, professionals are able to identify problems that may lead to health issues and future problems.
Cost of roof insulation in Newmarket, Ontario
When deciding to improve the insulation of your residence or office within Newmarket, Ontario, it is recommended that you contact a professional installer to first get some advice on your current situation. Getting their evaluation will be important to help you decide which would best fit your needs. A number of factors are needed to be considered when getting a roof insulation project. However, for those who just want to get an idea of a roof insulation costing, one has to consider the average costing of materials and labor. Let us use the following variable and information to get a sample quotation:
Project: Spray foam insulation of the attic of a house
- Total area to be covered: 1,600 sq.ft.
- R12, 2lb spray foam insulation: average price per sq.ft. for is CAD 1.40
- Labor & installation (preparation, installation, cleanup, & other materials needed): average price per sq.ft. is CAD 1.10
Based on the information above, you must first multiply the average price per sq.ft. of the R12, 2lb spray foam insulation to the total area of the attic. The amount would come up to CAD 2,240. Then the labor & installation cost per square foot is multiplied to the total attic area. This results to CAD 1,760. By adding both totals, the final project cost will be CAD 4,000. This is just an estimate quotation and may still change based on the actual location.
Based on the estimate it may be seen that installing a roof insulator may be costly but when done right, you can expect to have considerable savings on your energy bill even if your location experiences extreme climate changes. Improving the insulation also means you do not need to install energy saving equipment, like a solar energy system, to compensate for the heating and air-conditioning systems you have at your residence or office.
You should also remember the importance of talking with a professional team before you implement a roof insulation project. Experts can do the work evaluation and eventually the installation to keep a safer and healthier environment.
