Unsulation boards PIR SOFT LE
INCREASING ENERGY EFFICIENCY REQUIREMENTS IN CONSTRUCTION PRESENT NEW CHALLENGES FOR INVESTORS AND CONTRACTORS.
To meet these growing demands, we offer the PIR SOFT LE insulation board, which is the key to achieving high thermal comfort while keeping heating costs low.
This board features an exceptional thermal conductivity coefficient of λ = 0.022 W/m•K, ensuring outstanding thermal insulation. The PIR SOFT LE board consists of two multilayer gas-tight laminate with an external layer of aluminum foil with a rigid PIR foam insulation core in between. The board is available in two versions: with straight edges (SE) or L-shaped edges on all four sides (LS).
Types of PIR SOFT LE

ADVANTAGES OF PIR SOFT LE unsulation boards
▪ Excellent thermal insulation – λD = 0.022 W/m·K,
▪ Easy and quick installation,,
▪ Outstanding dimensional stability under changing operating conditions, preventing the formation of thermal bridges,
▪ Resistance to fungi and mold due to the closed-cell structure with gas-tight facings,,
▪ No biological threats – rodents do not penetrate the rigid PIR foam, ensuring long-term durability of the material without the need for replacement.

APPLICATION:
PIR SOFT LE insulation boards are an excellent material for use as insulation:
- of three-layer walls,
- of flat roofs,
- of shed roofs,
- of floors,
- of terraces.


ENERGY EFFICIENCY
They help to build a facility which is provided with an excellent thermal insulation and protected against loss of heat. With use of PIR SOFT LE unsulation boards it is possible to achieve the same insulating power with a lower thickness compared to mineral wool or expanded polystyrene foam, which proves that Paneltech PIR SOFT LE unsulation boards are the most efficient out of all commercially available insulating materials.
