Types of rigid insulation

Which rigid insulation should I Choose? How do you install rigid insulation? Rigid -foam insulation packs a lot of R-value into a thin package, but not all rigid foam performs the same.

Choose rigid insulation wisely, and consider the effect its characteristics will have on the performance of the your project, overall product cost, and the best way to get the bang for your buck. The most common insulation materials are fiberglass, cellulose and foam. Tip: The type of insulation you need depends on which type is currently installed and the required R-value. Rigid insulation is one of the best tools to reduce your energy costs.

Install it anywhere from the roof to the foundation. You can even place it under the foundation slab. Rigid foam insulation , also known as insulating boards, provide high R-values. They keep your home at a comfortable temperature without the need to crank your heat. Rigid fiber or fibrous board insulation consists of either fiberglass or mineral wool material and is primarily used for insulating air ducts in homes.

While all foam insulation products are derived from petroleum, some of the key differences include water resistance, R-value per inch, compressive strength, facings, permeability to water. EPS is the insulation used most widely in insulated concrete forms and structural insulated panels (SIPs). EPS has the lowest average R-value of the three most common types of rigid -foam insulation , around R-per inch.

It also is the least expensive. EPS is suitable for ground contact and can be treated to resist insects. When choosing rigid foam insulation , you have three main options: Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R- to R-) of any rigid insulation. This type of rigid foam usually comes with a reflective foil facing on both sides, so it can also serve as a radiant barrier. This post outlines some of the different types of rigid insulation , and highlights which might be the most suitable for your application.

Vacuum Insulation Panels. There are three main types of rigid foam insulation : expanded polystyrene (EPS), extruded polystyrene (XPS), and polyisocyanurate. Key differences are R-value per inch, water resistance, compressive strength, permeability to water vapor, facings, and of course, cost.

All foam insulation products are petroleum-derived. The basic types of foam board insulation include: polystyrene, polyurethane or polyisocyanurate. They include expanded polystyrene, extruded polystyrene, and polyisocyanurate unfaced or foil faced. DOW products has lots of information on their site about different foam board products here. Thermal Insulation for pipes, ducts and equipment.

Free 2-day Shipping On Millions of Items. There are three types of rigid foam insulation : Expanded polystyrene (EPS): This material is also known as beadboard. What is rigid foam made of?

It has an R-value of 3. Many of the types of rigid board insulation discussed above are used to create tapered insulation systems. Depending on the roof assembly, each type has coinciding benefits and drawbacks. Types of rigid foam board insulation include EPS (expanded polystyrene), XPS (extruded polystyrene) and polyisocyanurate. Rigid foam board is commonly used in both retrofits and new construction as a continuous insulation (not to fill in wall cavities).

The Best Insulating Rigid Foam. As well as having rigidity and durability, rigid foam also provides acoustic insulation by minimising the level of sound travelling through walls or raised floors, such as in flats etc. This option can be more expensive than other insulation types and requires the help of a pro, but it can also cut down on other home weatherizing tasks, such as caulking. When using rigid Insulation in residential and commercial properties the most common boards used would be Polyiso (polyisocyanurate), EPS or XPS. Each type of insulation board are very different and carry different R-values and compressive strength.

C578’s Types IV, V, VI, VII, X, XII and XIII. XPS complying with Type XII or XIII generally is not intended for use in roofing applications. If you are working with experienced contractors the job can go incredibly quickly.

You have to know about the various kinds of insulation types and make sure you are using the best material for the job, but once this decision has been made there is.
