2LB MEDIUM DENSITY CLOSED-CELL FOAM

 

Exotherm Spray Foam Systems specializes in closed-cell or 2lb foam insulation, which is a rigid insulating material with the highest LTTR (Long Term Thermal Resistance) of any insulation product.  It’s R-value ranges between 5-7 per inch, and when the required minimum thickness of 50mm is installed, it is both a vapor and air barrier.  We use Genyk Boreal Nature polyurethane foam, which is formulated based on renewable substances and recycled products.  Genyk Boreal Nature is blown with lavender water, generating a pleasant odour during the application and also has the highest R-value of any SPF on the market today.  2lb is the premium product for those looking for superior insulation and overall energy efficiency.  It is best used in walls, ceilings, floors, garages or anywhere it’s unmatched performance may be required.

 

WINDOW & DOOR
SEALING

 

Under insulated framework around windows and doors can greatly contribute to a homes energy loss and overall comfort.  At Exotherm, we use Great Stuff pro series window and door insulating sealant by DOW to stop the infiltration of air and moisture, which in turn maximizes energy efficiency.  This gun applied, low pressure-build formulation, which expands to take the shape of gaps, creates a durable, airtight and water resistant seal between a window or door frame and it's rough opening.  When properly installed, it is proven not to bow or distort the frame, becomes tack free within 3-10 minutes, and if need be, is trimmable within 60 minutes of being applied.  It bonds to vinyl, metal, wood and composite surfaces, cures in 8 hours and meets the stringent durability requirements as an air leakage sealant set out in CAN/ULC S710.1, CAN/ULC S711.1 and CCMC 13074-L.

 

0.5LB LIGHT DENSITY OPEN-CELL FOAM

 

Light density open-cell foam SPF is commonly known as half-pound foam.  It is a semi-rigid material with a sponge like appearance that expands during installation and creates small open cells.  Due to its ability to expand during application, it fills cracks, crevices and voids, while adhering to irregular surfaces or substrates to form an air sealing insulation.  Unlike medium-density closed cell SPF, it is not a vapor barrier.  When installed at 5.5 inches or more, it does however act as an air barrier.  Also, it provides sound reduction by blocking and absorbing air leakage.  At Exotherm, we use Genyk B-1050 open cell spray foam, which is also fully water blown.  It’s most commonly used in garages with living quarters above it, as these require R31 and 6-8 inches of half pound will do the trick nicely, which, as stated above, also creates an air barrier to keep out harmful gas emitted from vehicles.

 

 

BATTS

 

FIBERGLASS

 

Fiberglass is the most commonly used insulator, as it is one of the more cost effective and affordable of the available applications on the market. Fiberglass, which is made of plastic reinforced by extremely fine glass fibers, typically comes in either batts, or rolls, and helps to slow the spread of heat, cold and sound in structural assemblies. Batts have an R-value of R2-R3, and are installed between studs in wall cavities and ceilings. Since they are not an all in one system, they do require a vapor barrier on the warm side of the wall when installed.

 

ROCKWOOL

 

Rockwool, which is commonly referred to as Roxul, is also known as mineral wool or stone wool. It is an excellent insulator and sound dampener, and also possesses a very high melting point. It is made by heating rock until it is liquid, and then is spun into long, fibrous threads which are captured and tightly bound together. These strands, once made into baatts, retain heat by trapping pockets of air to slow heat transfer. Its common uses are for residential and commercial insulation, in temperature sensitive applications, or as a sound retarder. Althouh it does possess a slightly higher R-value of R3-R3.5, it is rare for an entire structure to be insulated with Roxul, as it is more expensive than the more commonly used fiberglass batt.

 

LOOSE-FILL

 

Loose-fill materials are commonly blown into attics and hard to reach places, through a hose that is attached to a specialized blowing machine. The two most common of these are fiberglass and cellulose, both of which are made of recycled materials. Cellulose, which is the oldest form of insulation, is slightly denser than fiberglass, thus giving it a higher R-value of R3.2-R3.8, respectively. It is made from 80% recycled newspaper, is very environmentally safe and is treated with flame retardants and insecticides. Fiberglass, which does have a lower recycled content at 20% recycled glass, as well as lesser R-value than cellulose at R2-R3, does however have less flammability than its counterpart, thus making it a more popular choice amongst homeowners. Both are a more cost effective solution to insulating an attic than spray foam, whether a new home, or topping up existing insulation.

 

LOOSE-FILL REMOVAL

 

Over time loose-fill insulation sags and settles, animals and insects are known to inhabit attics and help speed up this process as well, and also may leave the insulation overridden with feces. Due to this, many of our clients choose to remove their old loose-fill insulation, which is done through a hose by a high powered insulation removal vacuum into specialized bags, and install new insulation. Once removed it is taken to dump sites to discard of safely by our highly trained crews. Other reasons for this may include the removal of older insulation that before was not seen as such, but has now been deemed unsafe by many health officials, such as vermiculite or asbestos, or wanting to install spray foam or spray foam/loose-fill hybrid, both of which require the removal of the existing insulation prior to the new installation.

 

SPRAY FOAM/LOOSE-FILL HYBRID

 

Another application becoming more popular amongst homeowners when insulating their attic is the spray foam/loose-fill hybrid. This is largely due in part to it being more affordable than an all spray foam application, and a more efficient solution than an all blown-in loose-fill scenario. In this application, if need be, the existing insulation is removed, then 2 inches of closed-cell SPF is applied providing an air and vapor barrier and sealing of the attic floor, then this is topped up to the required R-value with loose-fill fiberglass or cellulose. More and more people are opting for the hybrid application as they become more aware of the benefits of spray foam, but at the same time, don’t want to break the bank.

 

DRYWALL

 

Drywall, which is also often referred to as gypsum board, is made of calcium sulfate dihydrate (gypsum), with or without additives, and is extruded between thick sheets of facer and backer paper. The plaster is mixed with fiber, typically either paper or fiberglass and various additives that decrease mildew and increase fire resistance and lower water absorption. Drywall is used in the construction of interior walls and ceilings, and became popular in North America as a better and speedier alternative to lath and plaster. Our professional drywall installation crews work at an efficient pace to complete jobs in a timely manner, and our top-notch tapers complete the job in an unparalleled fashion, with a pristine level 4 finish. We offer full wall system packages (insulation, drywall), thus making the process much smoother for homeowners and builders, as our teams work together harmoniously to make sure the job is done right, and eliminating the need to subcontract the work out to a number of different contractors, who more often than not aren’t working on the same page.

 

VAPOR BARRIER

 

A vapor barrier, or vapor retarder, is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through the wall, floor, ceiling or roof assemblies of buildings. This is to prevent interstitial condensation, where moisture or water vapor moves into building cavities in 3 ways, by air currents, diffusion through materials, or by heat transfer. Vapor barriers slow the rate in which this occurs, and each different application has its own moisture vapor transmission rate that is established by standardized test methods. These tests separate each material into 3 categories, impermeable, semi-permeable, and permeable, the requirements of which are broken down in the NBC (National Building Code). When installing spray foam insulation, our installers are not required to install a vapor barrier as spray foam, when applied at 50mm or more, is an air and vapor barrier. When installing batt or loose-fill in wall cavities, ceilings or the attic, our installers will dutifully apply 6 mil polyethylene where required, as it is an approved vapor barrier.

 

THERMAL BARRIER

 

According to building codes across North America, spray foam requires a thermal barrier which separates it from flames in the case of a fire. Typically, this is ½” gypsum board, which is an approved thermal barrier, but in cases where drywall is not being applied, another approved thermal barrier is an intumescent coating. Our installers are certified by International Fireproof Technology Inc., the makers of one of the most popular applications available on the market, DC315, which has been designed and stringently tested for the global market. All approved SPFs can be found on their website with varying application standards, though most are usually recommended to have 24mils of coating applied, thus attaining a 15-minute thermal and ignition barrier. This is done with a specialized paint machine by our skilled applicators, and measured with a wet gauge to ensure the proper thickness is reached, leaving a greyish-white finish when completed. More often than not, this is used in commercial applications where SPF is often left exposed, but more and more homeowners are beginning to opt for this as well in certain areas of the home.

 

SPRAY-APPLIED THERMAL CORKSHIELD

 

One of the most green energy efficient products on the market right now is Vipeq's sprayed insulated cork material, or Thermal Corkshield. This revolutionary system, which is derived from 100% cork, offers many beneficial properties, some of these being: it is lightweight, mildew resistant, durable, flexible, fire-retardant, water resistant, and possesses acoustic and thermal insulation capabilities. The bark is removed from the oak tree every 8-10 years on average, and can be removed from the said tree many times over a 200+ year span, all without causing any damage to the tree, and while releasing large amounts of oxygen into the air during the trimming process. It is available in a variety of colors, and is perfect for those wishing to add an extra thermal break to their home or property, without the need to remove the existing exterior surface, whether brick, stucco, or siding, corkshield can be applied directly to the desired substrate, all while adding a refreshing new look to the structure. This application will provide an added layer of insulation to the building, and help to drastically reduce utility bills, as it will not go below 0 degrees, or above 30 degrees Celsius. This Class-B fire rated material closely resembles stucco, and is a quicker, more efficient and cost-effective solution than the aforementioned application, an its high elasticity properties allows it to contract and expand according to the weather, therefore it will not crack or bend like paint or stucco, and its high impermeability makes the diffusion of liquids or gases difficult. Corkshield will absorb the impact to whatever surface its micro suction cups adheres it to, therefore extending the life of your home, and providing peace of mind with a 10 year manufacturer warranty when applied by one of our certified technicians.
