One easy way to determine if there is insulation in the wall cavities, or if they are empty, is to remove an electrical receptacle cover. Turn off the power to the circuit. Take a kitchen butter knife and carefully slide it along the outside of the electrical box and in the open cavity. If there is any insulation, you should be able to feel it when you slide the knife on the outside of the electrical box.
By drilling a small 1 inch (2.5 c.m.) hole between the studs and installing cellulose fibre blown insulation. Our knowledgeable applicators, with specialized equipment to deliver the required amount of air pressure, will blow the dry insulation into the wall cavities tight enough so you will have little or no insulation sagging over years to come.

At Lambton Insulation we drill 1 inch (2.5 c.m.) holes between brick joints, starting one and half bricks from the corner, using a masonry bit. This may be followed by a wood bit if wood is present behind the brick. Once the cavity is opened, we use a stud finder to find the next cavity and mark it. Each successive stud gap is found and professionally filled with cellulose fibre blown insulation
Single storey houses require one row of holes near top of eve edge and under the windows. One and a half story houses require two rows. Full two storey houses will require two to three rows of holes.
Yes you can. At Lambton Insulation we lift up the vinyl siding and all the holes are drilled behind the siding. A special tool is required for this application. We place small blocks behind the siding to hold it upwards and start holes, approximately eight inches (40 c.m.) from the corner of house drilling holes between studs and filling the cavities with the same equipment as used in brick houses. Once the cavities are full the siding is replaced with no notice or interruptions on the exterior of the house.
Again, this process is done by drilling holes but, through the siding between every stud with a 1 inch (2.5 c.m.) carbide drill bit, starting approximately.eight inches (40 c.m.) from corner of house wall.
This area can be done by the home owner using conventional batt insulation. Check you national building code for minimum R-values required. Lay the first layer between rafters and the second layer of batts crossed over the first layer. This will minimum heat loss between the cracks of the batts.
Lambton Insulation provides the customer with attic blown insulation, this save you time, and is less expensive, even with the labor included! This also provides a seamless layer of insulation through out the attic to reduce heat loss. There are a variety of different types of blowing insulation on the market today. They include cellulose fibre, fibre glass and rock wool blown insulation, just to name a few. (See Photo)
These areas are called knee walls and to insulate them, you can place an R-13 batt between the vertical inner wall studs, followed by an R20x23 batt, nailed across, for R-32 total.
To provide a total seal, we suggest spraying the wall areas with icynene foam insulation. The floor areas in the knee walls should then be blown with loose insulation to minimum code or better.
In the basement or crawl spaces of your house, all outside walls need to be insulated with Icynene or Poly-Urethane foam insulation. This type of insulation provides a total seal to keep out that cold air that is cooling down your floors. Batt insulation does not work in this situation because it will not form a seal in the header areas. Ground temperature in southwestern Ontario is approximately 54 to 55 degrees Fahrenheit (12 to 13 degrees Celcius) and basement walls need to be insulated to the floor when heating above these temperatures or you will be spending your hard earned dollars heating the outdoors.

Do not insulate the underside floor areas with batt insulation or you may end up with moisture problems, which could result in wood rot on floor joists.
First of all, you must comply with building codes in your area. Here are the steps required:
Icynene Foam (see photos)is a two part system consisting of Polyicynene MDI and Polyicynene Resin. The two are supplied to a 1:1 proportioning unit, which hydraulically supplies a mixing gun with equal amounts of each material. Triggering the gun allows the material to be released to the substrate, where it reacts from the mixture and expands to 100 times liquid size, turning into a foam material (Icynene Insulation) which fills all cracks and open cavities in seconds.
Icynene foam insulation is an open celled foam insulation which helps to seal the building envelope. This allows the owner to manage the interior air, using controlled ventilation and eliminates 99% of the unwanted outside air-pollutants. Icynene foam insulation has no CFCs, HCFCs or formaldehydes and is incapable of supporting bacteria or fungus. In fact, Icynene foam insulation is endorsed by the Envirodesic® Building Program, which is sanctioned by the Lung Association.
Nothing performs like Icynene for filling cavities, nooks, and crannies.
A blower door test can be done to see if all cracks around the windows, doors etc. have been total sealed. This gives our customers total satisfaction. It also ensures the house will meet R-2000 standards (1.5 air changes per hr.).
Just remember you can buy appliances anytime, but you can only insulate once!
Poly-Urethane Insulation is applied in the same manner as Icynene foam insulation, but expands to only 30 times its liquid size. This enables the foam applicator to put on lighter thickness in such places as barns and drive sheds to deterrent rodents from tunneling or distroying the product. It also provides a total seal to the substrate. (see Figure).
Poly-urethane insulation for flat or low slope roofs provides a seamless membrane on the exterior part of the roof. This reduce the chances of leaks combined with a elastomeric coating over the foam insulation, which ensures years of satisfaction to come. It provides you with a new roof plus insulation all in one.
