FAQs

How much does SEALECTION™ 500 system cost?

SEALECTION 500 is considered to be more expensive than most conventional insulation; however SEALECTION 500 cannot be compared to conventional insulation. When using the SEALECTION 500 spray foam insulation system it actually air seals the building and eliminates energy robbing air leakage and the associated problems with moisture, mold and mildew, and condensation problems inside the walls. When calculating the actual cost, you need to consider the possible need to downsize the HVAC systems, eliminate building wraps, and eliminate a significant portion of the material and labor costs associated with an air sealing approach. It is erroneous to compare the cost of loose fill insulation to that of SEALECTION 500 spray foam insulation system. The invested premium to upgrade from standard fiberglass is an insignificant part of the overall cost of a home and your long-term energy costs. When you are planning to install an upgraded insulation package, remember that SEALECTION 500 is more expensive but it provides you with the best performance and comfort value. The additional upfront costs typically pay for themselves in energy savings within three years and will keep on saving you money every year thereafter. Your builder wants you to build the very best house; be patient and persistent if he is unfamiliar with our product, but ask for the product by name, SEALECTION 500.


Are there any issues around overheating of electric wiring?

There is no special requirement needed to encapsulate electrical wires other than what is required with all types of insulation. As with other types of insulation such as fiberglass and/or cellulose, when the properly rated size and type of electrical wires are used, there is no over heating of those electrical wires..


Are there any compatibility concerns with other building materials?

SEALECTION 500 is stable in the presence of most solvents found in binders, bituminous materials, wood preservatives, and sealers. It is resistant to facers containing plasticizers, fuel, mineral oil, weak acid, and weak bases, which are typically found in residential and light commercial construction materials.


Does SEALECTION™ 500 adhere to metal studs?

SEALECTION 500 adheres well to steel studs and other natural materials such as cement board, wood, etc. commonly found in residential and light commercial construction. Since SEALECTION 500 will adhere to almost all surfaces in the home, areas that do not require SEALECTION 500 insulation such as windows, doors etc. must be protected from over-spray.


Is it possible for a homeowner to install SEALECTION™ 500 on their own?

SEALECTION 500 insulation must be installed by an Approved Applicator with specialized proportioning equipment. The installer has been trained to work with the chemicals involved and has also been trained in the building science to provide the best installation possible.


At what stage is SEALECTION™ 500 system installed?

The SEALECTION 500 insulation system is installed after the windows, doors and roof are in, the electrical and plumbing inspections are completed, and after any other electrical or mechanical system located behind the drywall is installed. It is the last installation to take place before drywall is installed.


Does SEALECTION™ 500 Insulation support the growth of molds and mildew?

No, SEALECTION 500 insulation offers no food value therefore it cannot support bacteria or fungal growth. The effective air sealing characteristics of SEALECTION 500 prevents the movement of hot air to the cold parts of the walls. This effective air-sealing process prevents condensation from taking place within the wall cavities. The elimination of condensation within the wall assemblies prevents the growth of molds and/or mildew.


Does SEALECTION™ 500 contain Urea Formaldehyde, CFC or HCFC’s?

No. SEALECTION 500 does not contain Urea Formaldehyde, CFC’s or HCFC’s. This insulation is a semi-rigid urethane and an open cellular plastic foam, in which water is incorporated as the sole blowing agent. SEALECTIONTM 500 has obtained the seal of approval by the Environmental Choice Program of Canada (equivalent to US-EPA).


Are there health concerns with SEALECTION™ 500?

No, SEALECTION 500 is a “green” product. It meets off-gassing requirements of CGSB 51.23 92 for new residential construction. No toxic or carcinogenic products were detected.


How long does SEALECTION™ 500 stay flexible?

SEALECTION 500 remains flexible throughout the life of the building. As the building expands and contracts with changes of season and temperature, SEALECTION 500 will move with the changes without destroying the seal.


Can SEALECTION™ 500 be applied in an existing wall?

We do not recommend that SEALECTION 500 be applied in existing walls. However, we have had good results in using SEALECTION 500 in the attic and in the crawl space (if applicable) without disturbing the walls in a retrofit application. The reason is that a large portion of your energy loss is caused by the “chimney effect” – hot air rises, therefore creating air movement within a house.


What is the R-Value of a SEALECTION™ 500 insulated wall or ceiling?

R-Values of insulating materials are measured in laboratories and are designated a nominal R-Value per inch. In the wall or ceiling of a building most factory-made insulation materials suffer a reduction in performance due to air leakage and infiltration. The insulating value of many building components may be as low as 50% of the nominal R-Value of the insulation they contain. By contrast, the insulation of a wall containing SEALECTION 500 insulation will perform closely to that of the laboratory tested R-Value of the material, and it seals the wall cavity from air infiltration as well. The SEALECTION 500 insulation system is particularly suited for steel or wood frame construction. SEALECTION 500 expands 120:1 as it is installed, adhering to surrounding building components. It completely seals joints, crevices and voids, including difficult-to-insulate spaces such as steel stud “U” and “C” sections, double studs, and non-standard stud locations.


What is the R-Value of a SEALECTION™ 500?

The R-Values of SEALECTION 500 insulation is rated at R-3.8 per inch. In a nominal 4-inch wall, the R-Value is about R-13, in a 6″ wall about R-21.


Does SEALECTION™ 500 break down, sag or shrink?

No, SEALECTION 500 insulation is stable. It does not shrink or sag. The reaction that created SEALECTION 500 insulation is irreversible and it cannot break down into its constituent parts.


What are the advantages of SEALECTION™ 500?

As well as simplifying the construction process for the builder, SEALECTION 500 spray foam insulation eliminates the major causes of building envelope problems, air-borne moisture movement and entrapment. Blower door tests have shown that steel framed homes insulated with SEALECTION 500 spray foam insulation and with no polyethylene vapor barrier routinely measure under the 1.5 ACH50 rating for the most energy efficient home. Heating and cooling costs are typically reduced by 30 to 50%. Smaller and less expensive heating and cooling equipment (properly sized) can be used.

SEALECTION 500 is inert and stable over a long term. It will not settle or compact over time. It offers stable R-value and is chemically and physically stable under normal conditions between (-60F and 180F).


What is SEALECTION™ 500?

The SEALECTION 500 spray foam is a complete insulation and air barrier system that insulates and air seals walls, floors and ceiling cavities against air movement, including spaces around electrical outlets, baseboards, and where the walls meet windows and doors etc. This means that outside air (hot or cold) cannot seep through walls causing drafts or cold spots. It also means that hot humid air cannot enter the walls and condense on cold surfaces causing molds, mildew and premature decay.

SEALECTION 500 spray foam insulation is applied by Approved Applicators, which provides a truly effective method to construct energy efficient homes and buildings. SEALECTION 500 is a semi-rigid thermo-set polyurethane foam (see Product Specifications), which is a cellular plastic composed of millions of microscopic cells of which most are open. The application of the product is done at the job site by Approved Applicators, providing a custom installation of the insulation. The application technique and nature of SEALECTION 500 make a perfect fit to all cavities irrespective of size or shape.

By virtue of its low permeability to air, its adhesion to other building materials, and its flexibility, SEALECTION 500 becomes much more than just insulation. It provides superior air leakage and sound control for residential construction. SEALECTION 500 is a one step insulation, and air barrier system. SEALECTION 500 eliminates the labor intensive work associated with air-tightness detailing when insulating with conventional insulation products.

SEALECTION 500 is an significantly reduces air infiltration, unlike “loose fill” insulation, which does not air seal the building cavities. Air infiltration robs the insulation of its R-value. The superior air sealing characteristics of the SEALECTION 500 system provides virtually the same R-Value in the field as it does in the laboratory. Cold air in winter and hot muggy air in summer cannot pass through our SEALECTION 500 foam as it can through other insulating materials cheating those products of its performing R-value.
