Please refer to our <a href=/services/sprayfoam/>spray foam</a> insulation section and view the manufactures data sheets for more information.";
fader[0].msg[2] = "Yes. Mold and moisture problems are a common place with many insulation systems. Moisture can become trapped if the permeability of a surface is too low. Poly sheeting, which is often used in fiberglass and cellulose insulation systems, can trap moisture from escaping because of it's low perm rating.  It is also easy for a penetration to occur in the poly sheeting, for example, from a staple or nail. This penetration will cause moisture to flow in and build up if it does not have another way to exit. ccSPF insulation qualifies as a vapor barrier/retarder at two inches or more but doesn't trap moisture like poly sheeting.";
fader[0].msg[3] = "The ccSPF is a two component mixture that is sprayed onto a substrate by a certified <a href=http://www.sprayfoam.org/>SPFA</a> professional. The insulation is sprayed on a exposed surface usually after the electrical and plumbing services are in place. As the mixture comes together, it expands up to 100 times its initial volume in seconds, filling any cavities, voids, or gaps.";

Fiberglass and cellulose insulation lose their R-value during extreme temperatures and ccSPF does not. ccSPF is  mold &amp; moisture resistant unlike fiberglass &amp; cellulose. Fiberglass batts have an R-value of 3.5 per inch thickness. Cellulose has an R-value of about 3 to 4 per inch thickness. Spray foam insulation has an R-value of about 7 per inch depending on manufacturers specifications. Cellulose and fiberglass insulation can settle over time which can allow air flow to occur.

It is the last installation to take place before drywall installation. On existing homes, the spray foam insulation can be installed to the attic, roof line, and sub-flooring to seal in the house. It is more cost effective to leave existing interior wall insulation in place.";
fader[0].msg[11] = "An outlet can be easily added because ccSPF insulation can be drilled, scraped or shaven. Depending on the framework you use, you may even have space to add wiring or an outlet over the insulation after it is in place. Contact us today to learn more.";

Many systems employ an air exchanger, which pre-conditions incoming outside air to control humidity and energy efficiency. This type of design along with spray-foam creates a true Thermal Envelope.";
