There are a few different types of roof thermal insulation available. These include XPS, Mineral wool, and Polystyrene. Let’s discuss the pros and cons of each type of material. Then, decide which is best for your home. There are a number of benefits to each, so it’s important to choose the right one for your roof.
XPS
XPS roof thermal insulation provides a highly efficient and effective means of insulating a roof. As an extruded material, XPS does not require the use of excipients, making it easy to install. XPS roof thermal insulation is also available in continuous layers, which can be installed over a metal roof.
One advantage of XPS insulation is that it can be recycled and reused with a new roofing membrane, saving the cost of replacing the existing insulation and hauling it to a landfill. Additionally, because XPS can be used over again, it can contribute to a sustainable design strategy by helping to qualify for credits in the U.S. Green Building Council’s LEED program.
Unlike EPS, XPS insulation is hydrophobic and has a homogeneous closed-cell structure. In EPS, the voids are responsible for a larger amount of water absorption. This is because EPS is filled with air instead of a blowing agent, resulting in less thermal resistance. The more dense an EPS product is, the lower the voids.
Extruded polystyrene is an ideal roof thermal insulation for a wide variety of roof types and styles. Its unique properties make it suitable for a variety of roof designs and types, including white single-ply roofing and metal roofing systems. Its low water absorption makes it an ideal solution for these types of roofs.
Mineral wool
Mineral wool roof thermal insulation is a cost-effective way to reduce heating bills and preserve warm air. Mineral wool is typically laid between the rafters of a house and secured with metal brackets and ropes. Mineral wool is also easy to install and has a long service life of 70 years, so it doesn’t need to be replaced often. Mineral wool can be a pain to lay on your skin, though, so wear gloves when working with it.
The material itself has excellent thermal properties. Its thermal conductivity is around 0.25 BTU/ft.2 @ 100 degF (24 degC), and its density is around 4.4 lbs./m3. The insulating qualities of mineral wool make it the perfect choice for roof thermal insulation.
Another reason mineral wool roof thermal insulation is such a great choice is that it’s a sustainable option that can reduce your energy bills while reducing your carbon footprint. Mineral wool insulation is available in a variety of thicknesses, and the R-value of the material is 15 or higher, which makes it more effective than fiberglass insulation. Whether you’re remodeling your house or building a new one, mineral wool is a great choice.
The process of manufacturing mineral wool requires specialist equipment and materials. It starts with glass cullet and quartz sand that are heated to high temperatures. These materials are then sprayed with a special solution of tackifiers and polymers. Then they are formed into a mat. The material is then mixed with polyol and isocyanate and cured in a spraying process.
The advantages of mineral wool are extensive and often include fireproof qualities. In addition to its excellent thermal properties, mineral wool also prevents noise. It is also durable and resistant to mold.
Polystyrene
Polystyrene roof thermal insulation can be an excellent choice for roofs in colder climates. It is lightweight and durable and exhibits consistent thermal performance. Another advantage is its low cost. It is also moisture-resistant and bacteria-free. In addition, this insulation is easy to install.
Polystyrene insulation is made of cellular polystyrene, which makes it a perfect fit for roofs. This type of insulating material is lightweight and provides effective water resistance. It is compatible with most types of commercial roofing systems. It also meets ASTM C578-04 and CAN/ULC-S701-01 standards.
Extruded polystyrene is manufactured from foam beads in a mould and then heated or steamed to expand the beads. The beads then fuse together, forming a closed cell structure. This material is suitable for single-ply roofing, metal roofing systems, and many other roof systems.
Polystyrene insulation comes in a variety of board sizes and thicknesses. The material can be made as thin as a single layer or as thick as two. It can be installed on flat or sloped surfaces. It is often ballasted to ensure positive drainage. However, it must be protected from high temperatures and solvent-based products. Additionally, certain thermoplastic roof membranes need a separation layer to prevent heat from penetrating.
EPS, or expanded polystyrene, is widely used for roof insulation. Different densities provide different R-Values. The higher densities work best on concrete slabs. EPS also comes in crickets and is perfect for roofing applications. In addition, EPS is ideal for low-slope roof applications, such as flat roofs.
Polystyrene is a recyclable material. XPS is an example of expanded polystyrene, and Amoco Foam Products uses 50% recycled resin in its EPS.
EPS
EPS roof thermal insulation is an effective and affordable way to increase energy efficiency. Its recyclable properties make it environmentally friendly and it doesn’t contain harmful CFCs, HFCs, or HCFCs. Moreover, EPS roof thermal insulation has no formaldehyde content, so you can rest assured that the insulation you use will not cause a health risk to your family.
Another benefit of EPS roof thermal insulation is its durability. EPS can last for many years without losing its effectiveness. The material is lightweight, resistant to high temperatures, and offers excellent water resistance. Moreover, it is compatible with most roof systems. It is certified to meet ASTM C578-04 and CAN/ULC-S701-01 standards.
EPS insulation has long been known as “green” insulation. It contains recycled content, meets minimum performance standards, and is delivered directly to job sites. In addition, it has never contained ozone-depleting gases like CFCs. While many other insulation materials have had to phase out the use of CFCs or have reformulated their entire manufacturing process, EPS insulation has a proven track record and is one of the best options for roofing insulation.
EPS roof thermal insulation is compatible with almost all types of roofing membranes. Whether you’re installing it on an existing roof or putting it on a new building, EPS roof insulation can help you save energy and money. Foam-Control(tm) tapered roof insulation is compatible with built-up roofing, modified bitumen, and single-ply membranes.
EPS panels are also useful in insulating foundations. They can come in a range of densities and compression strengths, making them an excellent option to meet any design load requirements. One typical application is a floor with hydronic heating, which is critical to maintaining a comfortable temperature and a low energy bill.
