Soundproofing your home

If there’s anything harder to find in this age of technology it would be silence. Everywhere you go noise pollution abounds. Getting a good night’s rest can be extremely frustrating if you live near a source of noise, whether is be neighbours or traffic. On the contrary, we deserve to live a quiet life.  Many have turned their homes and offices into quiet havens that are soundproof. By doing so, they have purchased temporary peace and tranquility when the reach the confines of their homes or offices. Aside from the doors, walls that have some openings in it are entry points of noise. When these openings are not filled, sound may be travel through it. When you build a double wall, there is a gap in between. You can fill in the gaps by injecting foam insulation, in order not allow the sound to travel and pass through the walls. These are the areas that most likely cannot defend against noise. This can also have the effect of raising your home’s market value. If you ever decide to sell your home, buyer’s will take note of the soundproofing and this will be added points for them to choose your property over others. After all, who doesn’t want to move into a home that guarantees them peace and quiet? Contact us for more information about using foam insulation for...

Energy efficiency still important, regardless of rebates

With the high cost of fuel, electricity prices skyrocketing, and inefficiency of older homes. insulating is still a cost effective way to make your home more energy efficient.  In the short term you will be more comfortable in your home, and at the same time the heating and AC bills will drop.  Payback can be had in a few years.   We can insulate older homes with no insulation in the walls,  or in many cases add to the existing insulation in the walls, with either blown in cellulose or injection foam insulation.   We also offer infrared thermal scanning of your home, to identify problem areas of efficiency, including drafts, missing or low insulation in attics or walls, and duct leakage....

Thermal Bridging

A thermal bridge is created when materials that are poor insulators come in contact, allowing heat to flow through the path created. Insulation around a bridge is of little help in preventing heat loss or gain due to thermal bridging; the bridging has to be eliminated, rebuilt with a reduced cross-section or with materials that have better insulating properties, or with an additional insulating component (a thermal break) When insulating a basement wall with foam insulation, leave a space behind the studs, allowing the foam to provide that thermal break between the exterior wall and the stud.  If using batts,  put a layer of polystyrene insulation board along the exterior wall before you put up the studs and batt...

weatherstripping

Weatherstripping prevents air from leaking through gaps around doors and the moving parts of an operable window. Weatherstripping should be easy to replace. To be effective, it must close gaps completely. Weatherstripping should be flexible and spring back to its original shape. It should allow you to open and close windows and doors easily. Weatherstripping can be applied to the tops and sides of any door frame. V-shaped weatherstripping creates an excellent seal by making contact with the edge of the door. It maintains a good seal even if the door warps. At the bottom of the door, apply weatherstripping to either the sill or the door itself. When weatherstripping your door, use a durable material that can withstand traffic but is flexible enough to adapt to changes caused by humidity and...

Limit drafts around electrical outlets

Electrical outlets are a huge source of drafts entering your house.  By installing foam gaskets (available at most hardware stores) behind the cover plate, you will limit drafts from getting into your home through these areas.  In addition to the foam gaskets, you can also put the plastic safety plug covers in each outlet.  This will serve 2 purposes, to keep children safe from unexpected shocks, and also seal the plug holes, which can allow drafts...

Retrofit wall insulation

Cellulose, and Airkrete foam are a couple of  the most common types of blown- and sprayed-in insulation materials in the retrofit market in. And it is worth it. Retrofitting insulation into existing walls and attic space can achieve a 20 to 30 percent savings on heating bills. The learning curve and the inconvenience factor make most other blown-in applications impractical for a homeowner, and spray-in insulation should be left to the pro. Cellulose is composed of up to 85 percent recycled newsprint. The remaining content is commonly a mixture of borate and ammonium sulfate that functions as a fire retardant. These chemicals also deter rodents, insects, and mold.   Avoid materials containing formaldehyde and mineral fibers. Dry cellulose is very popular for blown-in insulation applications. Cellulose’s small particles fill voids and corners well as the material is shot into the walls. Dry cellulose offers an “itch free” installation, but respirators and safety goggles must be worn during the process. Cellulose dust is fine and tends to take a long time to settle. Airkrete cementitious foam is a magnesium-based product that is derived from seawater. Because of its consistency, foam is the most effective product for retrofitting into existing walls. Foam will work its way around any obstacle, providing a near-100 percent wall fill (cellulose, for example, may not fill completely around bundles of wires or pipe runs and leave random voids). Unlike bottled foam insulation used to seal small gaps around pipes and wiring, it does not shrink or expand.   Airkrete cementitious foam is the most costly insulation to retrofit, but is the most benign in regards to indoor...

Keeping the heat up by keeping the cold out

It is important to note that most homes in North America have substantial air leaks which can cause poor energy efficiency throughout the home. Many of these air leaks can be rectified quickly and cost effectively by paying attention to the major players, exterior doors and windows. More times than not, an air leak can be fixed with a simple door jam or caulking in a window...
