There is an enormous selection of building materials available on the market today, and choosing the right materials can quickly become overwhelming. When it comes to insulation, you can choose from blankets to beads, boards and even blocks. From there, you have even more choices to make, such as the chemical makeup which can include various types of foam, fiberglass, and more.

Rmax simplifies the selection process in this article by breaking down a tried-and-true building component that they've been manufacturing for decades: rigid foam insulation.
Let’s start by answering the simple question: What is rigid insulation? Rigid insulation, like all insulation, is a building material used in construction that creates a thermal barrier to separate the inside of your building from the outside. Rigid insulation is often produced as rectangular-shaped boards that are installed in a modular fashion.
One way to define rigid insulation is by answering the question: What is rigid insulation not? Rigid insulation can be differentiated from other types of insulation by the following characteristics:
Dimensional Stability: Unlike beads, spray foam, or batts, rigid insulation holds its manufactured shape rather than conforming to its surroundings. This means it can be used outside the wall cavity since it doesn’t require a container to support it.
Compressive Strength: Other types of insulation like cellulose or fiberglass blanket carry virtually no compressive resistance, while polyiso rigid insulation boards typically boast a compressive strength of 20 psi or higher. This means you can walk on rigid insulation without damaging it.
Installation Method: Rigid insulation can be installed by fastening, adhering, or loose-laying modular boards to structural sheathing, studs, walls, or decking.
Now that we’ve established a basic understanding of what rigid insulation is, let’s answer the question: What is rigid foam insulation made of? There are three main types of rigid foam insulation that you’ll see in the construction industry:
Expanded Polystyrene (EPS)
Extruded Polystyrene (XPS)
Polyisocyanurate (Polyiso)
Each of these rigid insulation types is made of different raw materials (resins and additives), and each one has its own manufacturing process. The final product comes out looking very similar for all three varieties of rigid insulation: rectangular 4’x8’ boards in various thicknesses ranging from ½” up to 6”.
Polyiso insulation contains an additional component that is not included in EPS or XPS. That’s because the manufacturing process requires a facer on either side of the foam. Polyiso consists of a foam core that is sandwiched between two facers. The facers are made of a material like foil or fiberglass-reinforced cellulose. EPS and XPS, on the other hand, do not require a laminated facer and have a homogenous makeup.
Rigid insulation is versatile and can be used throughout the building envelope, including inside and outside of the wall cavity, roofs, attics, and foundations. Rigid insulation, like Rmax Durasheath®, is used on exterior walls under siding and wall finishes, on the interior of basement walls, and as protection to newly installed waterproofing on the outside of foundation walls for backfilling.
Rigid insulation is the go-to material in commercial roofing systems. It’s used to insulate the building from above and create a drainage slope on flat roofs. In fact, to meet current energy codes, many commercial roofs require more than five inches of rigid insulation above the roof deck and below the roof membrane!
A clear advantage that rigid insulation has over other types is its ability to be applied in a continuous manner. Continuous insulation is when your insulating material goes uninterrupted across the surface of your building. Rigid insulation is inherently a continuous insulator.
Additionally, the boards are often applied in two layers. When installed this way, joints are staggered and there is less opportunity for leaks to occur through the insulation joints. If you’re looking for insulation that enhances your building’s energy efficiency, rigid foam insulation gets the job done, by achieving a thermal resistance of R6 per inch for polyiso rigid foam insulations like Rmax Thermasheath®.
For an even bigger boost in energy efficiency, polyiso rigid foam insulation has another major advantage. It can be laminated to air and vapor barrier materials so that it can be installed in a single application. The Rmax ECOMAXci ® Wall Solution combines a fire-rated polyiso foam core with a 12 mil foil facer. When properly installed with joints sealed, it can function as an all-in-one air and vapor barrier, plus insulator.
There are many types of insulation boards available in the market. It can be difficult to decide which one is the best for your specific needs. In this article, we will discuss the different types of insulation boards, their pros and cons, and how to install them. We will also provide information on how to choose the right insulation board for your home.
Insulation boards are a construction material used to insulate buildings. There are many different types of insulation board available on the market, each with their own advantages and disadvantages. Here’s a quick overview of some:
These are a type of foam plastic, they are typically more expensive but offer better thermal insulation and soundproofing properties when used in rigid panel insulation. If your plan is to insulate cavity walls, external walls or generally looking for something with the best insulation properties we would recommend using PIR insulation board.
These are made of polystyrene, are one of the most frequently used types of insulation sheet. We often utilise this material as a form protective covering for household appliances.
This is another type where the edges are thinner than the sides. These are typically used in commercial applications, such as in the insulation of flat roofs.
These are a series of cut slots that allows for boards to fit tightly together without any gaps. You will normally need these for underfloor insulation, as the grooves provide good airtightness.
These are similar to tongue and groove edging, but with a small difference. Named after the process used to build ships long ago, today’s shiplap edged insulation boards have matching grooves that fit each board snugly against adjoining boards.
This is a popular choice for internal wall insulation, as it is easy to install and provides good thermal insulation. However, it is not as effective at noise insulation.

This is another option for internal wall insulation as well as flooring insulation. A rigid insulation board is more difficult to install than a foam board but offers better thermal insulation.
These are designed specifically for roofs and are available in a variety of materials, including fiberglass and polystyrene. They are easy to install and provide good thermal insulation.
This is a less common type of insulation board but can be used for a variety of applications, including underfloor insulation. It is available in a variety of materials, including fibreboard and cellulose, and can be installed either horizontally or vertically.
Cavity walls and roof insulation are both essential if you want to keep your home warm in the winter and cool in the summer, but what’s the difference? And which one should you choose for your home?
Insulation boards are a great option for cavity walls and roofs. It’s made of rigid foam, which has a very low thermal conductivity. This means it’s great at preventing heat from escaping your home, making it warmer in the winter and cooler in the summer.
Insulation board is also very lightweight, so it’s easy to install. And because it doesn’t absorb water, it won’t rot or mould like some other insulation materials can. Plus, it’s an eco-friendly option as it’s made from recycled materials.
So if you’re looking for an insulation material that’s effective, easy to install and eco-friendly, insulation board is a great choice.
There are a few things to keep in mind before opting for this type of insulation. First, insulation board is not as effective as other types of insulation, such as blown-in cellulose or spray foam.
Second, some can be difficult to install, and if not installed properly, it can actually create gaps in your insulation that will reduce its effectiveness.
Finally, insulation boards are also more expensive than other types of insulation. While it may have some benefits, such as being easy to handle and cut, these disadvantages should be considered before using insulation board in your home.
When shopping for insulation boards, it’s important to make sure you’re getting the right type and the right amount of coverage. Make sure you consider factors like R-value, thickness, size, and fire rating when making your selection
It’s also wise to shop around and compare prices so that you get the best deal possible. Be sure to check reviews from previous customers as well, as these can give you a better idea of what kind of product quality and customer service you can expect
Overall, selecting the right insulation boards is an important decision when looking to improve the energy efficiency of your home with extra insulation. With so many options out there, it’s important to do your research in order to find the best option for your needs.
