Benefits of Using XPS Insulation
XPS insulation is great for many reasons. It makes homes more energy-efficient. Knowing its benefits helps homeowners make smart choices.
Energy Efficiency
XPS insulation keeps your home’s temperature steady. It has an R-value of 4.6 to 5.0. This means you use less energy for heating and cooling.
Using XPS can save up to 40 BTUs for every BTU used. Adding more layers reduces heat loss. This makes your home more energy-efficient.
Moisture Resistance
XPS insulation absorbs very little moisture, just 0.3%. It’s perfect for places with lots of moisture, like basements. It keeps water out, protecting your home.
Durability and Longevity
XPS insulation lasts over 100 years if installed right. It works well in many places. Its strength is over 300 kPa, making it great for heavy loads.
Common Applications of XPS Insulation
XPS insulation is used in many places. It’s good for buildings in homes, offices, and factories. It helps save energy and keeps buildings strong.
Residential Construction
In homes, XPS is used in walls, roofs, and floors. It has a high R-value, which means it keeps homes warm in winter and cool in summer. This helps lower the cost of heating and cooling.
Commercial Buildings
Commercial buildings use XPS for keeping warm and dry. It’s great in cold places like storage rooms. XPS also keeps moisture out, which is good for buildings.
Industrial Uses
Industrial places use XPS for floors and foundations. It’s strong and can handle heavy things. It’s perfect for places that need to stay at a certain temperature, like farms or airports.
Comparing XPS Insulation to Other Types
Choosing the right insulation is key. We need to know the differences between XPS, EPS, and Polyiso. Each has its own benefits and costs. Let’s look at how XPS compares to EPS and Polyiso, focusing on R-value, moisture resistance, and where to use them.
XPS vs. EPS
EPS is cheaper, costing about 25 to 30 cents per square foot for a 1-inch panel. But, it has an R-value of 4 to 4.5 per inch. XPS is stronger and absorbs less water, making it better for underground use.
XPS vs. Polyiso
Polyiso has a higher R-value, from 5.6 to 7.0 per inch. It’s often used for roofs. XPS is better at fighting moisture, which is important for long-term use.
Performance Metrics
Here’s how XPS, EPS, and Polyiso compare:
| Material | R-Value per Inch | Cost per sq. ft. (1 in. thick) | Moisture Resistance | Compressive Strength |
|---|---|---|---|---|
| EPS | 4.0 – 4.5 | $0.25 – $0.30 | Lower | Variable, requires higher density for comparable strength |
| XPS | 5.0 – 6.0 | $0.42 | Medium | Higher |
| Polyiso | 5.6 – 7.0 | $0.70 | Medium to High | Higher |
XPS insulation is reliable for keeping things warm and strong. It’s not the cheapest, but it’s good at fighting moisture. This makes it a great choice for certain jobs.
