SPRAY FOAM INSULATION

---

 Yes. Building codes provide for the use of spray polyurethane insulation in the Foam Plastic section. This section of the code also describes the use of thermal barriers. 

Not only is Icynene safe, with home energy bills soaring over the last few years, installing Icynene spray foam insulation has got benefits all year round, and can also save you up to 50% on your energy bills. 

 Normally, spray polyurethane insulation is installed at the same point in the construction cycle as other types of insulation. That is, it should be installed after the rough plumbing, electrical wiring, and heating and air conditioning ducts have been installed. If you decide to seal the entire exterior shell with spray polyurethane, spray insulation may need to be applied in some areas before the ductwork is installed. 

The product may also be applied in existing homes during retrofit / renovation.

 Yes. Building codes provide for the use of spray polyurethane insulation in the Foam Plastic section. This section of the code also describes the use of thermal barriers. It seems like the radiation of heat through the windows would make the attic hot. Windows in a conditioned attic are similar to windows in your home. They are holes in the insulation. The energy they allow through them will have to be made up from your heating or cooling system. Consider removing them or covering them from the inside in some manner and insulating them. 

Not practically. Spray polyurethane application requires complex equipment and a skilled installer with training in the safe and proper installation of the polyurethane system. 

 Great question as we hear this a lot. Unfortunately for you DIYers, spray polyurethane foam (SPF) equipment is not for rent. Installation of SPF needs to be done by a well-trained installer. It's not as easy as it looks. There are some small kits on the market, but they are made for very small projects like sealing joints and cracks. 

Closed-cell spray polyurethane foam (SPF) is an excellent option for you. Closed-cell SPF is listed as a Class 5 Flood Damage-Resistant Material per FEMA. This means it is "Highly resistant to floodwater damage, including damage caused by moving water. These materials can survive wetting and drying and may be successfully cleaned after a flood to render them free of most harmful pollutants." It is the only insulation material that meets this classification. You can read all about it in the FEMA Technical Bulletin 2. It would be an excellent idea to install closed-cell SPF into your walls the next time you have to open them up.

No it's not, 24 hours after spray foam has been applied there will be no toxic chemicals present, as the gas is made inert. This makes it perfectly safe for humans or animals to be present in the sprayed area . 

 A two-part mixture is applied by trained professionals to the surface to be insulated. The spray mixture expands rapidly to fill all cracks and voids, completely and permanently adhering to wood, masonry, metal, concrete, and most other construction materials. 

Insulating the underside of a trailer with spray polyurethane foam is much like insulating the underside of a home in the crawlspace. It is a good idea and should help with the energy bills especially if there is no insulation there presently. 

To help reduce outside noise through a wall, either open or closed-cell spray polyurethane foam is a good choice. The most important choice is to use the correct type for your climate zone. 

In a hurricane zone spray foam can increase the wind uplift resistance of the roof deck, thus protecting your roof from hurricane damage.

It is not recommended to spray or pour spray polyurethane foam in a wall cavity because the expanding force may cause damage to the interior or exterior sheathing. The best solution is to install the foam when either the interior or exterior sheathing is removed during a remodel. 

Typical bulk insulation products can qualify for the tax credit including pour in place and spray foam technologies.

To apply the homeowner will need a manufacturer certification statement along with the IRS form 5695 for residential energy credits.

Please always check with your CPA for current tax credit laws, as the government constantly updates regulations and credits.
