RESIDENTIAL WALL FOAM INSULATION -Existing Wall Injection Foam- MINIMAL INVASIVENESS MEANS AIR TIGHT R-VALUES and LOWER CONSTRUCTION COSTS

There are many ways in which injection foam  can be used, including as insulation, sound proofing, sound deadening, condensation control, sealant, caulking material and void fill. These spray foam applications apply to construction, HVAC, cold storage, plant and facilities maintenance, roofing, truck, trailer, bus and RV insulation, marine flotation and insulation, pool and spa insulation, stage, film props and special effects.

FAQ: Injection Foam Insulation, existing walls:  Questions

What is  Residential Wall Foam Insulation?
Injected insulation is a hybrid belonging to one of the oldest groups of synthetically produced thermosetting plastics. Phenolics, as they are referred to, were first synthesized in 1907. Today, phenolic plastics are well known for their durability, structural integrity, and extraordinary fire resistance. Phenolic plastics are used in electronics, automobiles, machine parts, fire-proof coatings, adhesives, tools, and thousands of other commercial and household items. When made into a foam insulation, phenolics are one of the safest and most efficient thermal and acoustical insulation products available.

Where can Wall Foam Insulation be used?
Practically any wall void or cavity that requires insulation can be filled with Retro Foam.

It is ideal for use in: basement Walls, wythe cavities, outside walls, interior walls cement block cores, Interior & Exterior wood and steel stud wall systems,
pre-cast concrete panels, pipe chases, Filling property line voids between high-rise buildings, Retro Foam is the best choice for existing commercial building and residential home insulation!

Does Existing wall fill foam emit any toxic gasses during installation or when subjected to high temperatures?
No. When tested in accordance with the Federal Hazardous Substances Act, Retro Foam by-products of combustion are significantly less toxic than those produced by the burning of white pine... a common wood used extensively in residential home construction. When tested for hazardous materials as listed in the EPA's Emergency Planning Community Right to Know Act under sections 311 & 312, test results show no toxic materials were detected, and combined formaldehydes were again undetected at a level of 0.0007%.

Is wall foam insulation fire resistant?
Yes. Most architects and engineers agree that it requires more than one specific type of test to determine the fire characteristics of our insulation product. The ASTM E-84 tunnel test, although an excellent method for testing surface burning characteristics of a product, does not necessarily give an overall picture of how that product will act under different fire conditions. Existing wall foam can be installed in interior wall and exterior wall cavities, and has  been subjected to all applicable fire tests in redundancy in order to obtain the most accurate profile possible. It has performed in every case with astounding results.

Can wall foam insulation improve the fire ratings of a wall system?
Yes! For many years existing wall injection spray foam has engaged some of the most reputable independent laboratories in the country to test our Foam product. Using the ASTM E-119 procedure, fire tests were performed on many different standard and custom wall designs. Two identical walls were constructed - one empty, the other filled with Tripolymer foam. In every test, the choice of product we use on a filled wal,l showed an increase of fire ratings from 50 to 150 percent! Injection foam insulation does not melt or vaporize like other foam insulation materials when subjected to the ASTM E-119 testing. Because of it's unparalleled fire resistance, our wall fill foam has been approved by many state and local building and fire departments as the only foam-in-place insulation product to be used to increase fire ratings on existing non-compliant wall systems.

Is our foam corrosive?
No. Unlike urea formaldehyde type foams that rely on strong mineral acids for setting and final curing,  Existing wall injection spray foam is created by using synthetic cross linking compounds, producing a self neutralizing, non-corrosive foam product.

Can wall spray foam insulation be used to insulate and reduce sound transmission in steel or wood stud drywall construction?
Yes. Existing wall injection spray foamis are installed in over 15 million square feet of wood and steel stud drywall annually, providing customers with the safest, highest quality thermal and acoustical foam insulation available.

Can wall foam be used to insulate Cement block wall systems?
Yes. wall foam has been used for over 34 years as a core fill insulation in all types of block type construction.

When can wall foam be installed in new Cement walls?
Any time during or after construction has been completed! By using the top-fill method or via the more common side fill pressure injection system, Existing wall injection spray foam will completely fill all empty cores and joints in all interior and exterior walls.  

Can wall foam insulation be used to reduce noise through walls and ceilings?
Yes. Our Existing wall injection spray foam has an STC rating of 53 in a standard wood frame 2 by 4 wall with a single layer of gypsum board on either side.

Does wall foam insulation  expand after it is installed?
No. Unlike polyurethane which expands anywhere from 20 to 100 times its original liquid volume, Existing wall injection spray foam is totally expanded once it leaves the installation equipment. No further expansion occurs after it has been installed keeping your walls safe from "hydraulic expansion damage"!
