Fiberglass cement felt for PIR insulation board facing excellent thermal insulation and fire resistance

What are Fiberglass cement felts?
Fiberglass cement felt is a type of material used in construction, particularly in the production of insulation boards such as PIR (Polyisocyanurate) insulation boards. It's made by saturating fiberglass mat with a cementitious mixture. This combination creates a durable and rigid material that offers excellent thermal insulation properties.

Here's a breakdown of its features and benefits:
1. Thermal Insulation: It provides effective thermal insulation, helping to maintain desired temperatures within buildings, which can lead to energy savings by reducing heating and cooling costs.
2. Fire Resistance: Due to the nature of its composition, fiberglass cement felt offers inherent fire resistance, making it a suitable choice for applications where fire safety is a concern.
3. Durability: The cementitious binder adds strength and durability to the fiberglass mat, making the resulting material resistant to wear, tear, and weathering. This durability contributes to the longevity of the insulation system.

4. Moisture Resistance: It is non-absorbent, the cement binder in fiberglass cement felt adds an extra layer of moisture resistance. This property is particularly beneficial in areas prone to moisture exposure, such as basements or exterior walls.
5. Dimensional Stability: Its shape and dimensional stability even under changing environmental conditions, ensuring consistent performance over time.
6. Ease of Installation:  Contractors can cut it to size as needed and affix it to various surfaces using appropriate adhesives or mechanical fasteners.
7. Versatility: It can be used in an insulating layer in walls,roofs, floors, and ceilings.
