Extruded Polystyrene Foam (XPS)
Expanded polystyrene (EPS)
Extruded polystyrene is produced from polystyrene, by extrusion. It can be manufactured in the form of the board in different sizes, edge, and surface shapes and with different compressive strengths, according to the intended use and the place of use. It is used for thermal insulation.
Extruded polystyrene foam (XPS) also known as the blue board. This insulation board is probably one of the most widely used foam board insulation products in the residential construction industry.
This is the product that I typically use to insulate basement walls. It’s reasonably priced, lightweight, and easy to use. This product is also used to insulate the outside of foundation walls and even under slabs.
Expanded polystyrene is made from the raw material of polystyrene. It is produced by using the pentane gas as a blowing agent so that the granules expand and stick to each other. It can be manufactured in the forms of the board in different sizes and with different technical properties according to the intended use and the place of use. It is used for thermal insulation.
EPS is acceptable for ground contact and can be treated to resist insects, it does absorb water. When applied as sheathing, EPS should be used over house wrap. Most EPS is unfaced, which means it is fragile and considered semipermeable, so it does not create a vapor barrier.
Rockwool products are ideal thermal insulation for industrial applications.
Rockwool insulation provides thermal and acoustical barriers for industrial and commercial applications.
Rockwool is a cost-effective insulation material that is especially suited to high-temperature insulation systems. It is made from recycled materials and rocks spun at high temperatures to create fibers that minimize heat transfer.
It can easily be molded or cut into the desired shape required for pipe sections, tank covers, or floor sections.
It can also be used for ovens in commercial or residential kitchens.
