Yes in most cases you can. It is not recommend if your insulation is contaminated by vermin, moist, or mildewed.

Exterior walls in new homes should be insulated to R-15 or higher. In existing homes, insulation can be blown into uninsulated walls. Have a qualified contractor check the walls and determine the feasibility of blowing in insulation.

Existing homes can easily have insulation installed in most ceilings and under timber floors, space permitting. However, walls and vaulted ceilings can only be insulated during the recladding or replastering process.

Yes, you can nail Fullback over styrofoam insulation but you must nail the Fullback and siding panel into a stud. No, this practice will not void the Fullback warranty as long as it is installed according to the Fullback instructions. The instructions can be found on our website (www.fullback.com).

Instead of adding more insulation, you should consider adding a radiant barrier system. This will have a greater effect on your cooling bills because it reflects heat away from the attic before it can reach the insulation and ceiling below. Without a radiant barrier, your roof radiates solar-generated heat to the insulation and, if they are mounted in the attic, your air conditioning ducts below it.

Increasing the level of insulation from 2-3 inches (R5) to 8 -14 inches (R30) can save $95 to $145 per year for every 1,200 square feet of ceiling area. For rectangular space, measure the length and width to the nearest foot and multiply them together. Length x Width = Area x = If your attic is not rectangular, break it down into rectangles. Find the area of each. Then add the areas together to get the total. Install batts or blankets of insulation between the joists or trusses.

Yes, but the preferred method is removal. The Uniform Building Code allows two (2) roofs on commercial (flat) buildings and three (3) roofs on residential(steep) buildings. Removal allows for inspection of the substrate, and the elimination of any wet, rough, and/or unstable existing materials.

Sometimes yes, sometimes no. It depends if there is space between ceiling joists. You need at least 24 inches opening between joists for the air cleaner. If you have adequate clearance, an attic crawlspace installation is similar to the drop ceiling scenario. Cut the appropriate sized hole in the ceiling material and finish the edges with the supplied trim. You'll need to use mounting hardware to support the weight of the unit from a suitable part of your building's framework.

If you have more than 7 inches of insulation, the extra energy savings for adding insulation will usually not cover the cost to add it. Before you insulate, be sure to seal all openings, cracks and crevices where air can escape from your heated space into your attic (see brochure below). Before you start, you can have your home evaluated for air leakage and overall energy efficiency.

A Cooler House installs blown fiberglass and cellulose attic insulation. Honestly both products are good insulators. Cellulose is more dense than fiberglass and therefore is a better barrier for air movement through holes in walls and ceilings.

Insulation is a very important part of your home's defense against heat intruding into the living area. But in the case of an un-vented, super-heated attic, insulation cannot stop the heat from getting through. Remember that insulation is designed to RESIST heat transfer, not STOP it. The heat will eventually get through. The best solution is to have your insulation SLOW the transfer of heat long enough for your attic vents to remove it.

Look at the insulation without disturbing it. Commercial vermiculate can range in size from very fine particles to large (course) pieces nearly one inch long. Vermiculate attic insulation is a light weight, pebble-like, pour-in or add-on (loose) product and is usually light brown or gold in color. It's texture is often compared to "popcorn"and can often be re-shaped when pressed together with the fingers.

Either loose fill (typically fiberglass or cellulose) or batt insulation (usually fiberglass) will work well. Batts are easier to install yourself, while many contractors find loose fill easier and less expensive to install.

Seal up the largest air leaks in your house--the ones that whistle on windy days, or feel drafty. The worst culprits are usually not windows and doors, but utility cut-throughs for pipes ("plumping penetrations"), gaps around chimneys and recessed lights in insulated ceilings, and unfinished spaces behind cupboards and closets. Better yet, hire an energy auditor with a blower door to point out where the worst cracks are.

Different jurisdictions have different code regulations but generally speaking, Enviroshake® can be installed over one layer of existing asphalt shingles, provided the roof is structurally sound underneath. There is considerable cost savings since there would be no additional cost for removal and disposal of the shingles. There are considerable environmental benefits to this as well because the old shingles need not be put in a landfill. No.

The attic fan should be centrally located. The fan should be mounted at the rear part of your roof. The hole should be 24 inches down from the peak of your roof.

All RecoupAerator® models are fully insulated and may be installed in uninsulated spaces. It is advisable, however, to install the unit in a space that makes it convenient to clean and periodically maintain the unit. Electric baseboard heaters are individual room heaters. They are available in varying lengths and are fastened to the wall near the floor. Each room has its own thermostat that can be wall mounted or unit mounted. The unit operates on a 240-volt current and is hard-wired (i.e.

Yes! The load capacity of the trusses above attached, enclosed garages with ceiling acces typically have the same capacity requirements as the rest of the residential roof.

While the Ontario Building Code does prescribe minimum insulation values, upgrading or exceeding these minimum values does not require inspections by the municipality.

Regardless of how much insulation you have in your attic, adding RB will save on your heating and cooling expense, and keep you much more comfortable. Energy savings for heating and cooling can vary from 17% to 25% depending on a number of factors, including climate, building configuration, materials used, site, family size and lifestyle. Your RB dealer has been trained to evaluate your home or business and advise you of your savings potential.

Placing the radiant barrier material directly on top of the attic insulation is not recommended. This type of installation allows dust to accumulate on the foil surface facing the roof. In time, the accumulated dust will negate the radiant barriers' reflective effect. If this type of installation technique is performed, it is strongly recommended that a perforated product be used in this type of application. If not, problems could develop with mold due to condensation.

radiant barriers perform a function that is similar to that of conventional insulation, in that they reduce the amount of heat that is transferred from the attic into the house. they differ in the way they reduce the heat flow. a radiant barrier reduces the amount of heat radiated across an air space that is adjacent to the radiant barrier. the primary function of conventional insulation is to trap still air within the insulation, and hence reduce heat transfer by air movement (convection).

Ground source heat pump systems will reduce your heating and cooling costs regardless of how well your home is insulated. However, insulating and weatherizing are key factors in gaining the maximum amount of savings from any type of heating and cooling system.

Insulation is beneficial to the comfort of your home all year round and can save you hundreds of dollars each year through savings on energy consumption, so when considering installing insulation, there is no time like the present.

If you're a home builder, you can build faster for less. An insulation professional will save you time on the front end and back end of a job. Experienced installers can insulate your homes faster than framers or general contractors, so you can keep your craftsmen focused on what they do best. Plus, you can be sure the job will be done the right the first time, eliminating callbacks. A professional contractor's expertise can help you in other ways too.

You should also wear the recommended protective clothing and equipment, including a disposable dust mask approved for protection from fibre glass, safety glasses or goggles, a long sleeve shirt, long pants, and gloves. A hard hat should be worn when working in an area where there is a possible danger of head injury.
