Why use insulation?
Reduce, reuse, recycle: this is our motto.
The whole point of insulation is to keep buildings cool in summer and warm in winter, and XPS is highly efficient at this, and can help reduce the amount of energy needed to maintain temperatures in buildings.
Green Buildings and Insulation
The buildings of the future must meet new and different challenges, they must not contribute negatively to global climate change, but they must be built taking into consideration that our natural resources are gradually exhausting at a fast pace.
A green building uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupant, as compared to a conventional building.
XPS vs. EPS
There are important differences between the different offerings of XPS and EPS insulations, look:
XPS
• Types: IV, V, VI, VII, and X
• Minimum R-values of 5.0 per inch
• Minimum compressive strengths ranging from 104 to 690 kPa (15 to 100 psi)
• ASTM C578 requires XPS insulation allow no more than 0.3 percent water absorption (by volume)
• XPS is manufactured through an extrusion process. Essentially, a molten material is extruded through a die where it expands into a uniform closed-cell rigid foam insulation board with no voids or pathways for moisture to enter.
EPS
• Types: I, II, VIII, IV, XIV, and XV,
• Minimum R-values ranging from 3.6 to 4.3 per inch
• Minimum compressive strengths ranging from 69 to 414 kPa (10 to 60 psi)
• EPS must allow no more than two to four percent water absorption (by volume), depending on the material type.
• EPS is manufactured with small foam beads placed in a mold and steam-expanded into a large form from which foam boards are cut.
