INSULATION

Insulation Services

Our insulation crew has a wealth of experience when it comes to making your home cozy. From lowering your heating and air conditioning bills to mitigating outside noise and vibration, insulation is an essential step in building and renovating. We install only materials of the highest quality, and make sure we provide insulation suited for your renovation or project.

Calgary Drywall Ltd provides residential and commercial insulation services. We insulate your walls, your garages, and your basements. These services give you the opportunity to transform previously unusable space into family friendly spaces you can enjoy year-round!

Types of Insulation

With so many types of home insulation on the market, it can be difficult to choose the most appropriate for your walls, attic, or garage. They vary wildly in terms of R-value, cost, and installation time, among others. 

Common types of home insulation include blanket insulation, concrete block insulation, rigid foam insulation, insulating concrete forms, loose-fill, blown-in, rigid fiber insulation, sprayed foam, and structural insulated panel. Each have their advantages. 

Calgary Drywall Ltd is here to help you select the best insulation type for your home, taking into account R-value need, climate, and budget. 

For more information, please don't hesitate to contact us with all of your insulation installation and selection questions. One of our team members will gladly help you make the best decision for your home!

How Insulation Works

Heat flows via through three mechanisms: conduction, convection, and radiation. Conduction is the flow of heat through a materials, or solids in general. Convection is the flow of heat through liquids and gases, much like how convection ovens circulate hot air. Radiant heat, like the heat from the sun, is absorbed by solid objects.

Most home insulation reduces heat conduction. Some types of insulation reflect radiant heat, reducing its absorption.

R-Value

R-value is a measure of thermal resistance. The higher a material's R-value, the stronger its insulating properties. Thicker, denser insulation material tends to result in a higher R-value.

The R-value needed depends on the climate, as well as the area of the home. Different insulation materials are appropriate for different areas of installation.

Calgary, Airdrie, Cochrane, and most surrounding towns are in zone 7A. The insulation requirements for our zone are:

  • Attics - R49 to R60

  • Walls - R13 to R21, depending on wall dimensions

  • Floors - R25 to R30

  • Crawlspaces - R25 to R30

Blanket Insulation

Blanket insulation is one of the most common types. It comes in the form of batts, or rolls. It can be made of a variety of insulation material, however the most popular tends to be fiberglass. Mineral wool, natural fibers, and plastic fibers are also widely available. Blanket insulation is fitted between studs, joists, and beams, and is used to insulate walls, attic trusses, and floor joists.

A facing will often be attached to the insulation material to facilitate insulation installation and add a barrier against air or moisture. 

 

Concrete Block Insulation

Foundations as well as some walls can be built using concrete blocks. Several techniques exist to insulate those, upping the building's R-value. Concrete block cores can be filled with insulation material. However, the most efficient way to insulate concrete blocks is to insulate their exterior. Several new types of concrete are available, with a much higher insulating potential than conventional concrete, such as autoclaved aerated concrete, autoclaved cellular concrete, and concrete-wood mixtures.

Foam Board and Rigid Foam Insulation

Foam boards are a very versatile form of insulation. They can be used in almost any part of the home, and provide a high value of insulation compared to other materials of the same thickness.

 

Appropriate for interior as well as exterior application, foam boards are typically made of polystyrene, polyisocyanurate, and polyurethane.

Rigid foam insulation reduces heat conduction through build structure and frame.

 

Insulating Concrete Form Insulation

Insulating Concrete Form (ICF) systems are types of poured concrete walls. They consist of foam boards or blocks, often strengthened with rebar - steel rods. Concrete is then poured, creating an insulated wall.

However, ICF block systems need to be treated with insecticide and waterproofed. The webbing around the block core can provide access to insects or groundwater. 

 

Loose-Fill and Blown-In Insulation

Loose-fill insulation usually consists of small mineral wool, cellulose, or fiberglass particles. This type of insulation is mostly made of recycled material, and is well suited for insulation of hard-to-reach spots, such as attics, or wall cavities.

 

Due to the particles settling as they are poured or blown in, the R-value of loose-fill insulation doesn't change proportionally to its applied thickness.

 

To achieve the desired R-value, insulation thickness must be measured once settled. 

 

Radiant Barrier Insulation

Radiant barriers mitigate downward heat flow, and as such are suited for hot, sunny climates. Radiant or reflective barriers aren't a necessity in Alberta, where keeping heat in during the winter is our main concern when insulating.

Rigid Fiber Insulation

Rigid fiber board insulation is mainly used in the process of insulating air ducts, and is usually done by HVAC contractors. This type of insulation usually consists of fiberglass or mineral wool, and can withstand the high temperatures required in air duct insulation.

Sprayed Foam Insulation

Liquid foam insulation can be sprayed, blown, poured or injected into walls, attics, floors, or cavities. There are two types of sprayed foam insulation : closed-cell foam insulation and open-cell foam insulation.

Open and closed cell insulation is typically made with polyurethane. Closed cell foam is denser and filled with gas, while open cell foam is spongier and filled with air. Closed cell foam has a higher R-value, providing stronger protection against moisture and air, but is much more expensive than open cell foam. Open cell foam, while cheaper and very light, shouldn't be used in basements as it is poorly protected against groundwater.

Liquid foam insulation is installed by spraying, typically. Slow-curing liquid foam insulation can be poured. Thermal barriers and vapor retarders should be installed over the hardened foam. Certification is necessary, as well as protective equipment, to install liquid or sprayed foam insulation.

Foam insulation tends to have a higher R-value than batt insulation, however it is much more expensive. Pros and cons must be weighed before choosing a type of insulation, as spray foam isn't always the most appropriate choice - something our crew will gladly do! Contact us for more information.

 

Structural Insulated Panel Insulation

Structural Insulated Panels (SIPs) are prefabricated structural building elements used in ceilings, floors, and roofs.

 

They provide uniform and precise insulation, and offer an airtight result.

 

SIPs usually consist of foam board insulation between two layers of facing material.

 

SIPs should be treated with insecticide, covered with a fire-rated material, and protected from vapor.

SIP structures need adequate ventilation as they are relatively airtight.
