General comment Clima Comfort insulation material utilizes a 4-layer underlayment, manufactured in the BMI factory in Ennepetal, Germany, and controlled within the laboratory facilities, to provide essential additional rain protection under the roof covering. Glued directly onto this underlayment is the insulation material, which is Kingspan's Kooltherm® K7 / Kooltherm® S7. This rigid thermoset cellular insulation is reinforced with glass fibre mesh fabrics and protected on both sides by a glass tissue-based facing. The final composite product is available in variable insulation thicknesses ranging from 60 mm up to 160 mm.
Material composition of the product:
Insulation (Kooltherm K7) ≈ 97.3%
Polypropylene Film ≈ 0.5%
Polypropylene Grid ≈ 0.5%
Polypropylene Non-woven Fabric ≈ 1.4%
Glue ≈ 0.3%
Material composition of the Kooltherm S7 insulation:
phenolic (PF) resin (63-73%)
catalyst and additives (15-20%)
blowing agent (5-7%)
glass fleece facings and reinforcement (7-15%)
For the placing on the market of the insulation product in the European Union/European Free Trade Association (EU/EFTA) (with the exception of Switzerland) Regulation (EU) No. 305/2011 (CPR) applies. The product needs a declaration of performance taking into consideration EN 13166 - Thermal insulation products for buildings - Factory made phenolic foam (PF) products - Specification and the CE-marking. For the application and use the respective national provisions apply.
BMI underlay and roofing membranes are manufactured exclusively in the BMI factory in Ennepetal, Germany and subjected to controls in the BMI laboratory facilities. Generally all permeables must comply with the EN 13859-1:2010 and most non permeables with the EN 13984:2013. There are a lot of other requirements, but this is both product and country specific.

The data quality is based on the principle that the data quality of the data of the processes that take place at the producer of the product must be higher than that of the other processes. For the processes at the producer, so at the factory in Ennepetal and Tiel, average product data have been used, retrieved from/ based on the ERP system. In addition to that as much as possible specific data from suppliers has been used. Every supplier was contacted. If no data were submitted background data was used.
The production process of the insulation does not deliver any coproducts. The applied software model does not contain any allocation. Production waste is sent to a waste incineration plant. Resulting electrical and thermal energy is looped inside module A1-A3 as the quality of the recovered energy is assumed to be comparable to the input energy. Environmental burden of the incineration of packaging and the product in the end of life scenario are assigned to the system (A5 or C3); resulting potential credits for thermal and electrical energy are declared in module D. Waste incineration with energy recuperation is assumed as end-of-life scenario.
For areas where accurate data was not available, such as transport or end-of-life scenarios, default values like for transport Lorry (Truck), unspecified (default) | market group for (GLO), EcoInvent 3.9.1 and for eol polyolefines (i.a. pe,pp) (i.a. pipes, foils) (NMD ID 57) for the main product and different eols for the packaging have been used. . For waste in A5 the European PCR for thermal insulation products EN 16783 was used, in which a standard percentage of construction waste of 2% is given under paragraph 6.3.5.3.
Kooltherm insulation EPD that has been used in the LCA calculation is based on the GaBi database (version CUP 2022.1.), generating an offset in the EPD.
