Foamular 150 vs 250: Which is Best for Your Project?

Foamular insulation is an ideal choice for many home improvement projects. It’s lightweight, easy to install, and strong enough to provide reliable support. But how do you know which type of foamular insulation is best for your project? This blog post will compare the differences between Foamular 150 vs 250 so that you can make an informed decision.

What is FOAMULAR® XPS Insulation?

Insulation is an essential component of any building, as it helps to keep the interior spaces warm in winter and cool in summer, while also reducing energy consumption and costs. There are many different types of insulation available on the market, each with its own unique set of properties and characteristics. One popular type of insulation is expanded polystyrene (EPS) foam, which is often used in both residential and commercial construction projects.

Foamular 150 vs 250: What's the Difference?

One of the most well-known EPS foam insulation products is Foamular 150 and Foamular 250, made by Owens Corning. Both products are made from EPS foam, which is a type of plastic that is known for its insulation properties. However, there are some key differences between Foamular 150 and Foamular 250 that are worth considering when deciding which one to use in your construction project.

Foamular 150 is a lower-density insulation product, while Foamular 250 is a higher-density product. This means that Foamular 250 is more resistant to compression and therefore provides better insulation performance. The higher density also gives Foamular 250 a higher R-value, which is a measure of an insulation's thermal resistance. This makes Foamular 250 an excellent choice for areas of the home or building that require a high level of insulation, such as attics and crawl spaces.

Foamular 150, on the other hand, is typically used in exterior walls and foundations. It is easy to install and lightweight, making it a popular choice for many construction projects. It is also moisture-resistant, which helps to prevent mould and mildew growth, keeping the interior spaces healthy.

When it comes to cost, Foamular 150 is a lower-cost option, while Foamular 250 is more expensive. However, it is important to consider that Foamular 250 provides better insulation performance, which can result in cost savings in the long run through reduced energy costs. So, it's always better to invest in a higher insulation performance product that will eventually save you money in the long run.

Rigid insulation is a type of insulation that comes in large, solid sheets or panels. It is made from a variety of materials including expanded polystyrene (EPS), extruded polystyrene (XPS), and polyisocyanurate (polyiso). These materials have different densities, which can affect the insulation performance of the product.

XPS stands for eXtruded PolyStyrene. The same as with EPS, we differentiate between higher R-value high-density XPS and lower R-value low-density XPS.

The density of a rigid insulation product determines its strength and resistance to compression. The higher the density, the stronger the product and the better its insulation performance will be. That's why polyiso insulation is often used in commercial and industrial applications where high insulation performance is required.

The Rigid insulation boards are commonly manufactured in 2x4, 4x4, and 4x8 board sizes. And their thicknesses vary from: 0.5, 0.75, and 1.5 inches. 1.5 rigid insulation is made from closed-cell polyurethane foam or expanded polystyrene, both of which provide excellent insulating effectiveness as well as additional protection against water damage.

2 rigid insulation has insulation properties that provide an effective thermal break, meaning it will block heat transfer from one side to another inside the home. 2 rigid insulation has an R-10 R-value, which is why it's also referred to as r10 rigid insulation.
