Technical purpose This EPD describes the potential environmental impacts of 1 lineal meter of glass wool insulation, CLIMPIPE
Section Alu2, with a thermal resistance equal to 1 K.m².W-1, a thickness of 33 mm and inner diameter of 15
mm . The intended use of this EPD is to communicate scientifically based environmental information for
construction products, for the purpose of assessing the environmental performance of buildings.
The Climpipe Section Alu 2 product is an ISOVER preformed glass wool pipe insulation, a pipe section with
a complete cylinder shape and with a longitudinal opening. Faced on its outer surface with an aluminum foil,
reinforced with glass mesh and polyethylene hot melt glue, which acts as a vapor barrier. An aluminium tape
is covering the longitudinal opening.
ISOVER glass wool products for technical insulation are CE-marked according to the EN 13172 (2011)
“Thermal Insulation Products – Evaluation of Conformity” and EN 14303 “Thermal insulation products for
building equipment and industrial installations. Factory made mineral wool (MW) products. Specification”.
The production site of Saint-Gobain Sweden AB, ISOVER in Billesholm, uses a small amount of natural and
abundant raw materials (sand, soda, limestone, feldspar) and high share of recycled glass cullets (more than
50% post-consumer recycled content of the glass). This material is converted by using fusion and fiberizing
techniques to produce glass wool. The products obtained come in the form of a glass wool pipe section.
On Earth, naturally, the best insulator is dry immobile air at 10°C: its thermal conductivity factor,
expressed in ?, is 0.025 W/(m.K) (watts per meter Kelvin degree). The thermal conductivity of mineral wool at
10°C is close to immobile air as its lambda varies from 0.030 W/(m.K) for the most efficient to 0.040 W/(m.K). For
technical insulation the thermal conductivity is declared for different temperatures.
With its entangled structure, glass wool is a porous material that traps the air, making it one of the best
insulating materials. The porous and elastic structure of the wool also absorbs noise in the air and offers
acoustic correction inside premises. Glass wool mainly containing incombustible materials and does not
react to fire.
Glass wool insulation is used in buildings as well as industrial facilities. It ensures a high level of
comfort, minimizes carbon dioxide (CO2) emissions by preventing heat losses through roofs, walls,
floors, pipes and boilers. It reduces noise and protects homes and industrial facilities againstfire.
Correctly installed glass wool products and solutions do not require maintenance and last throughout the
lifetime of the building (which is set at 60 years as a default value in the model), or as long as the insulated
building component is a part of the building. Glass wool 90-95% (REACH registration number 01-2119472313-44-0041)
