What is the recommended insulation thicknesses and densities for rigid polyurethane insulation for hot water piping application?
A contractor build two houses with 2 by 6 walls. He sprayed 1.5 inches of foam into the walls of one house and used standard fiberglass insulation for the other house.
The house with polyurethane insulation always had lower electric bills. They believe this is do to the fact that the foam is the worlds best insulation and it seals all air leaks.

Where could one find some Polyurethane Foam Insulation?
Polyurethane foam insulation is the most popular insulation on the market today. It is easily installed, it is sprayed into the walls where it coats and hardens. All home improvement stores carry it.
What raw materials are needed to make the insulation?
Common raw materials used to make insulation include fiberglass (made from silica sand), mineral wool (made from rocks like basalt or diabase), cellulose (made from recycled paper), and foam (made from petrochemicals like polystyrene or polyurethane). Each material has different properties and benefits depending on the application and desired performance characteristics.
What is two-component polyurethane?
All polyurethane contains two chemicals: a diol and a diisocyanate. (There's also a catalyst called DABCO and a few other items in there to modify the finished polymer, but for now let's stick with the two important ones.) A two-component polyurethane brings you the diol and the diisocyanate as two separate packages. There are a couple of two-component systems available to someone who doesn't own a plastics plant: car paint, where you put hardener in the paint to make it dry, and sprayed foam insulation. The way most of us get our polyurethane is as single-component systems, because diisocyanate is very poisonous. Polyurethane varnish, Gorilla Glue, and polyurethane construction adhesive all work the same way: the diisocyanate is missing parts. If you add water to it--whether through the air or by moistening the surface--the diisocyanate picks up what it needs and the urethane reaction commences.
What is foam blown polyurethane used for?
Foam blown polyurethane is used for insulation in buildings, appliances, and vehicles. It helps in regulating temperature, reducing energy costs, and providing structural support. Additionally, it is also used in packaging materials for protecting fragile items during shipping.
Can you spray paint polyurethane foam?
It is not recommended to spray paint polyurethane foam directly as the chemicals in the spray paint can cause the foam to deteriorate or melt. It is better to use a primer specifically designed for foam surfaces before painting.
What is the dimensions of batt insulation?
Batt insulation comes in a variety of widths, lengths and thicknesses.
What are the benefits of using sprayable polyurethane for insulation and coating applications?
Sprayable polyurethane offers benefits such as excellent insulation properties, seamless application for tight spaces, moisture resistance, and durability. It can provide energy savings, reduce air leakage, and protect surfaces from corrosion and wear.
Is polyurethane rigid insulation popular?
no

What is polyurethane foam insulation?
It is polyurethane that has been expanded with air when liquid, and formed into sheets, often 2-3 inches thick.
What does an R-Value tell you?
It is the measure of insulation against heat/cold afforded by varying thicknesses and composition of construction insulation materials. The higher the "R" Value the better the insulation characteristics.
What material is a cool box?
Usually polyethylene (casing) and polyurethane foam (insulation).
What purpose is polyurethane foam used for?
Polyurethane Foam as it can be cast, carved and sculpted, finds its uses in many applications in seating, insulation, seals and gadgets, automotive bushings, wheels and tires and more. They are used in filters of air purifiers; Self adherent polyurethane foam paddings are of great surgical use as supports and dressings. Polyurethane foam is used in seating, insulation, adhesives, carpets, plastics and even on vehicles. It is mainly used for insulation purposes as well as fire protection.
What is the recommended type of insulation for a 2x8 ceiling?
The recommended type of insulation for a 2x8 ceiling is typically fiberglass batt insulation. It is easy to install and provides good thermal performance for the space.
What type of insulation is recommended for a ceiling?
The recommended type of insulation for a ceiling is typically fiberglass or cellulose insulation. These materials are effective at reducing heat transfer and improving energy efficiency in a building.
What type of insulation is recommended for a crawl space?
Closed-cell spray foam insulation is recommended for crawl spaces as it provides a high level of insulation and helps to prevent moisture issues.
What are the benefits of using spray polyurethane foam roofing for commercial buildings?
Spray polyurethane foam roofing for commercial buildings offers benefits such as energy efficiency, durability, seamless installation, and insulation properties.
