Flat roof insulation
The flat roof can be a critical area, with losses of up to 30–35% of the building’s energy if not properly insulated. You can minimize energy loss by using THERMOTOP PIR boards in the thermal and waterproofing process of walkable, non-walkable, or green terraces.
THERMOTOP PIR boards stand out due to:
Very low conductivity coefficient (λ=0,021 W/mk)
High thermal resistance
High dimensional stability (does not settle, does not contract, and maintains its thermal properties long-term)
High compressive strength, between ≤ 130 kPa and ≥ 170kPa
Eliminate thermal bridges due to the "L" type joint
They have low weight, being easy to handle and install
Do not allow moisture penetration
They are compatible with all types of waterproofing membranes (bituminous, EPDM, PVC, etc.)
Chemically inert and safe to use
Do not develop mold, fungi, or other microorganismsDownload documents
The flat roof can be a critical area, with losses of up to 30–35% of the building’s energy if not properly insulated. You can minimize energy loss by using THERMOTOP PIR boards in the thermal and waterproofing process of walkable, non-walkable, or green terraces.
They contribute to increasing thermal comfort, reducing energy bills, and protecting the structure against humidity and temperature variations in the long term.
THERMOTOP PIR boards used in the waterproofing process ensure the durability and performance of the terrace.
