IS IT SAFE?

IS SPRAY FOAM HARMFUL?

 

Most health and safety issues that arise around SPF are linked directly to the quality of installation rather than to the actual product.  As spray foam is a chemical compound, it requires special handling from preparation to the installation stage by trained technicians, anything less may pose potential health risks, even after installation is complete.  Manufacturers and professionals have established rigorous standards, guidelines and criteria for handling spray foam compounds, and failing to meet these can pose dangers for both service providers and homeowners alike.  Once installed properly by a certified technician, SPF becomes inert (non-reactive) and non-corrosive, posing no threat to one’s family, or workers.

WHAT IS SPRAY FOAM INSULATION

 

SPF is a two component application made from isocyanate and polyol resin, that are pumped through an advanced proportioner and heated.  Air systems pump these components from two separate drums, through a heated hose to a mixing spray gun, where they are then spray applied to a substrate (i.e. stud wall cavity).  When combined, these components generate heat and undergo an exothermic reaction, causing it to expand up to 30-60 times its liquid volume seconds after it is spayed.  Once in place, this provides a high thermal insulating value with virtually no air filtration.  All SPF used by Exotherm contains polyols consisting of soy oil, corn oil, castor oil and sugar as well as recycled materials which are beneficial to the environment, and are formulated without any Ozone Depleting Substances (ODS).

WHY SPF?

 

2lb polyurethane foam has the highest R-value (the measurement used to determine the transfer of heat) of any readily available insulation used in homes or buildings, with an average R-value of R5-R7 respectively.  0.5lb or half pound polyurethane foam, typically has an R-value of R3-R4, whereas in comparison, blown fibreglass typically has an R-value of only R2-R3.  This means that when properly installed, SPF amounts to savings upwards of 40-50% on heating and cooling costs, while also saving the environment by decreasing fossil fuel and other harmful forms of energy usage.  In typical residential homes, almost 60% of heat loss is related to moisture in the air, and SPF, which has the most complete and efficient results of any application available on the market, forms an effective air and vapor barrier, which will not absorb water, and prevents condensation.  By eliminating moisture, it prevents the growth of mold and mildew, which in turn, reduces the likelihood of rotting wood and allergic reactions to mold spores, all while keeping pollutants, dust and allergens outside, as well as pesky vermin and bugs.  Foam insulation blocks all three forms of heat transfer; conductive, radiant and convective heat, and completely seals a given area, enveloping all openings, holes and cracks, including hard to reach areas that conventional products such as fibreglass cannot accommodate.  This long lasting, quality solution that won’t sag or settle over time, also adds structural strength to any building in which it is applied due to its rigid texture once dry.  Studies have shown that wall assemblies using spray foam have racking strength 2-3 times higher than traditional wall assemblies, thus making it the practical, go to solution for residential, commercial or industrial applications.

 

 

EXOTHERM

WHY
EXOTHERM?

 

At Exotherm, all of our applicators are highly skilled, licensed and trained professionals.  We strive to provide 100% customer satisfaction, and all of our clients have the comfort of knowing that our products and services are backed by a third party warranty through CUFCA (Canadian Urethane Foam Contractors Association Inc.), the largest association of its kind for spray foam professionals.  This program proudly supports all Accredited Contractors and Licensed Installers with a 3 year, $50,000 third party warranty.  In Canada, the National Building Code (NBC), as well as the Canadian Construction Material Centre (CCMC), reference two standards that apply to the manufacturing and installation of SPF.  Under the CUFCA  Quality Assurance Program (QAP), the gold standard in this field for over 32 years, we ensure that our products and installation standards exceed those set out in CAN/ULC-S705.2 and Can/ULC-S705.1, respectively.  These guarantee that customers are receiving professional, expert installation, while providing them with peace of mind.  Our job isn’t done until the client is completely satisfied, and in the rare case where problems may arise, or a job isn’t finished to the high standards for which our company stands, we will send someone back to make it right, at no extra cost.  We go to great lengths to ensure that all doors, windows and any other areas susceptible to overspray are properly protected, and leave the work area as clean as we found it once we are finished
