Walltite insulation is perfect for walls, roofs, basement walls, and concrete surfaces. We can create a gap-free, moisture-resistant insulation system to increase your comfort and save you money.
Walls
Moisture and air movement are two challenges of wood walls with conventional insulation. Air making its way through conventional batt insulation within the wall stud bays substantially decreases its effectiveness to insulate. Moisture buildup, frost formation, and even rust can be prevalent on nails and fasteners within the wall sheeting during cold weather conditions.
Fibreglass insulation is reduced in effectiveness by humidity and wind (air movement). With our extreme prairie weather conditions, moisture, condensation, and wind are typically present. Walltite is a closed-cell insulation that allows no moisture or air movement in the foam itself. These qualities will allow your home to be as efficient as possible and stay energy efficient.
Roofs
Conventional roof venting system moves warm, moist air out of the attic area to help prevent condensation and frost build-up on the roof deck and rafter fasteners. When the weather warms, it results in moisture stains on ceilings from water dripping off these same areas after thawing. Warm air from the room below permeating the insulation at the room’s edge can also cause severe problems with ice damming, which can damage your critical roof deck and rafters.
Spray foam application on roofs prevents these risks, making it an extremely wise choice. By applying the product directly to the back of the roof sheeting, conventional venting systems are not required, dramatically lowering heat loss. This same system greatly increases your home’s ability to stay cool in the summer.
In conventional attics, the space gets extremely hot in summer, and vents are used to dissipate some of the heat. With Walltite, there is no need to vent since the heat from the day cannot penetrate and cause those extreme temperatures. Sprayed foamed roofs will generally keep the attic area between +/- 5 to 8 degrees Celcius difference from the room below. This makes your home more comfortable and energy-efficient.
To sum up, with the Walltite insulation system on a roof we spray insulation directly to the sheeting, covering rafters and fasteners, have direct to sheeting spray, covering rafter cords as well as galvanized fasteners, and no roof venting required. We can supply you with an insulation system for your roof that will outperform any conventional insulation giving you a strengthened building envelope as well as reducing your heating/cooling bill.
Cathedralized Attics
Cathedralized attic space is where the spray foam insulation is applied to the underside of the roof deck but the ceiling is going to be flat. This system is standard for any spray foam application that we do in residential construction. Regardless of a flat or sloped ceiling choice, the spray foam stays against the roof deck and the air space within is warm and conditioned. This allows your flat ceiling to operate the same as a suspended ceiling will in a basement. Merely a means to finish the interior and facilitate lighting and details, but not having to become part of the envelope. This allows for the complexity of the design and the use of extensive lighting, speakers, TVs, or bulkheads, all the while not compromising the seal and insulation stability.
Basements & Concrete Walls
Concrete walls and conventional insulation systems result in mildew, moisture, condensation, and even frost build-up. Conventional insulation allows for air leakage in joist ends and wood/concrete tie ins. Seams in the sheeting and perforations for mechanical systems all contribute to the problem. This allows the incoming cold air to move down the concrete, condense, and form water. Cold weather can then lead to frost in the joists and on the walls. With the application of Walltite, you can eliminate these problems before they have a chance to happen, preventing issues such as damaged drywall or flooring, or rotting wall studs.
Walltite adheres directly to the surfaces on the joists and the concrete wall, sealing all the perforations. This unique insulation system eliminates all the common problems associated with traditional insulation. You’re left with a dry, warm, healthy, energy-efficient basement and additional living space.
Under-Slab
Closed-cell spray foam insulation, namely, Walltite by BASF has been certified for use under concrete floors. This makes it an excellent choice to replace rigid board insulation when groundwater levels are not high. Instead of having to deal with a board that wants to move, twist, and break, instead, the spray foam is applied to the aggregate. After the rebar and heating lines can be installed with great ease as the spray foam can be walked on without worry about it becoming easily damaged. The system is seamless and fast to install, quickly laying down in locations that would be time-consuming to achieve with rigid boards.
The foam also works to seal moisture and soil gas control. This is an approved system to replace poly, concrete, or rubber liners in crawl spaces for new construction. The foam insulation provides insulation for the floor at the same time as sealing it off from moisture and gases as per code.
Between Floors
Oftentimes clients will opt to have the floor systems between levels to be sprayed with low-density foam which we call “half-pound foam” because the density is half a pound per cubic foot. This foam is an excellent sound deadener and has been tested to provide building code of Canada certified STC rated assemblies. For the average home or commercial space, the foam is applied either because there will be a secondary suite in the basement, or sound deadening is needed for a media room or exercise space. The advantage this system brings is an application to the underside of the floor, liquid applied around obstructions, adhesion to wiring, ducts, and framing members within the floor assembly.
External Concrete
Walltite spray foam has been certified and tested to be a replacement for the external dampproofing of foundations. This means that as little as an inch of foam can be applied instead of tar or membranes to achieve a seal to the outside of concrete footings, frost walls, and full-sized foundations. Obviously, this is a weather dependant installation, however, the benefit is to have an insulation and water seal all in one system.
Spray Acoustics
Spray-on acoustical treatment can be applied to nearly any substrate, including wood, steel, concrete, and drywall. Thicknesses between 1 and 5 inches can be used. We use K-13 which is a quality product consisting of fiber mulch, binding agent, and finished surface. The fiber mulch is specially treated for colour, fire resistance, and mold and mildew resistance. Many colours are available. The most commonly used colours being black, grey, light grey, white, beige, and tan. Custom colours are available but require minimum order quantities that add to the costs.
K-13 is applied by our licensed and properly trained applicator staff. A hopper/blower machine, hose with a spray nozzle, and adhesive pump to wet the mixture are used. The fiber can then be spray applied to the roof or walls with a smooth texture that absorbs sound waves. This reduces the echo in the room and “deadens” noise. K-13 is naturally tough when applied using the proper glue to fiber ratios. This makes it versatile for a range of interior applications, such as rinks, gyms, bars, industrial and commercial buildings, and warehouse facilities.
Low Density Spray Foam
Low-density foam weighs half a pound per cubic foot. This cellular foam is applied into wall cavities to replace batt insulation. The foam is usually “just-filled” to the depth of the stud wall and any excess shaved flush. A poly vapour barrier and sealants are still used behind the drywall as the foam does not have a core density to qualify for being a vapour barrier on its own. The immediate advantages are custom liquid install to irregular shapes, lower installation cost over closed-cell, better sound isolation properties, no sagging or settling, adhesion to the framing and structure, no internal convection air movements, better insulation performance at extreme temperatures.
Usually, the low-density foam option is a more budget-friendly way to proceed or when deep blind cavities in floor and wall systems need to be over-filled.
