PRESENTATION OF THE COMPANY AND THE PRODUCT

THE COMPANY

STIFERITE s.r.l., with its headquarters in Padua, viale Navigazione Interna 54, has worked in the heat

insulation sector since 1963, the year in which the first machine in Europe for the continuous lamination of

polyurethane foam was installed in Pomezia (Rome). The product was called Stiferite, using the root of the

name of the company that was operating in Rome, Stifer, and the suffix ite, which refers to Isolanti

TErmici (Heat Insulation).

In 1968 the production was moved to the current headquarters in Padua and furnished with continuous

automatic machinery that has reached todays annual production capacity of about 9 million square

meters of heat-insulation polyurethane foam panels for the building industry.

The success of this product is also demonstrated by the fact that the Stiferite name has become synonymous

with polyurethane foam panels thanks to a constant collaboration with designers, customers and users who

have followed our work with enthusiasm, trust and constructive criticism.

Some of the recent successes to highlight:

In 2000 the launch of a new lamination line that is able to produce the new Stiferite panels in Polyiso foam

with D = 0,028 W/mK.

In 2001 received the certification ISO 9001:2000 for the development and production of insulation

panels.

In 2005 the development of a new environmental mission focusing on analysing and reducing the

impact of the productive operations and sharing environmental information with the public about the

product, also based on the application of the LCA methodology.

In 2007 STIFERITE develops a new line of panels with waterproof coatings characterized by a value of

heat conductivity at D = 0,024 W/mK. In July 2007 STIFERITE certified and registered the first

Environmental Product Declaration (EPD) for rigid polyurethane foam panels, referring to the Class S 60

mm thick STIFERITE panel, with the Swedish Environmental Management Council

In 2008 the newly adopted formulations for the Polyisio foam allows for the panels to be 80 mm thick ormore, with the heat conductivity at D = 0,026 W/mK.

In 2009 the study of the life cycle analysis of STIFERITE Class B 40 mm thick panels was published. It was

most widespread in the sector of insulation and waterproofing of coatings. An analysis by LCA of the

STIFERITE GT panels follows in this document.

THE GT PANEL AND PRO DUCT COMPOSITION

The STIFERITE GT panel is composed of Polyiso foam which is expanded by pentane and covered on

both sides by the special multi-layer coating Duotwin.

In the line of STIFERITE products, GT is the only panel that achieves excellent insulating performance (D

= 0,024 W/mk) without metal coverings. This is thanks to the Doutwin covering which is impermeable

to the gas contained within the cells and permeable for vapour.

STIFERITE GT is a heat insulating product used both for building and in industry. It is distributed through

traditional methods:

direct sales

wholesale of building materials

waterproofing and coverings companiesbuilding companies

prefabrication industry

transformation industry

Main applications:

Stiferite GT is mostly used for heat insulation of walls, floors and coverings.

Main features:

Beyond great insulation performance (D = 0,024 W/mK), Stiferite GT also guarantees excellent

dimensional stability, mechanical resistance, the ability to tolerate sustained temperatures up to 90-110

C and demonstrates good fire resistance.

Product composition:

The panel is made of polyurethane foam (88%W of which 6%W is pentane) and the multi-layer coating

Duotwin (12%w). The density of the Polyiso foam is 30 kg/m3.

Duration:

The polyurethane foams are the result of a stable and non-reversible chemical reaction that guarantees

consistency and lasting duration of its main characteristics and features. There is no evidence of physical

or chemical decay when the product is used normally. The actual duration of the insulation panel can

therefore be assumed to be equivalent to the life of the building or manufactured product where it is

located.

REPORT OF ENVIRONMENTAL PERFORMANCE

This section illustrates the main characteristics and results of evaluation of the environmental aspects

that were carried out from the viewpoint of the life cycle, according to the LCA methodology.

METHODOLOGY

The quantification of the environmental performance was carried out as set out by the EPD General

Program Instruction, according to the LCA (Life Cycle Assessment) and regulated by the international

standard ISO Series 14040. Since a specific PCR reference is missing, the study also considers the

document PCR Plastic Foam1.

The data refer to the production of 80 mm STIFERITE GT panels in 2008 and were gathered at STIFERITE.

The study also used the Boustead Model database for the general data selected. There is less than a 5%

contribution from the other general data in the final results.

Regarding the unit that the results apply to (working unit) to describe the panels' production, the

production of 1 m2

of panel was chosen. In order to make the total results as understandable as

possible, the results for the unit of heat resistance (R = 1m2K/W), mass (1 kg) and volume

2(1 m

3) are also

being presented here.

LIMITS OF THE SYSTEM AND MAIN HYPOTHESES

The analysis considered the entire productive system as illustrated in Figure 1, considering the single

operations which start with the production of the raw materials, then covers the production and

transportation of energy carriers and the final product, as well as the intermediary transportation

involved.

In the following diagram, the phases discussed using data coming from the company or from direct

suppliers (blue areas) can be distinguished from the data taken from reference databases (white areas).

Also distinguishable is the subdivision in the three main phases (Upstream, Core and Downstream). The

limits of the system do not consider the usage phase of the product and the recovery treatments of

energy and materials for which production discards are designated.

As for the employment of the materials, the specific technical data of the product is referred to, while

the data related to the production process are allocated based on the total production. In particular, the

auxiliary activities including heating, lighting, consumption of materials, air emissions are also included

in the parameters of the system.

Figure 1 General flow chart of the production process for GT panels. The production system at STIFERITE is identified with the Core Process.

The dotted cells are qualitative

In the case oftransport, the study examined the one necessary for the semi-manufactured products and

used materials as well as the phases of internal movement and delivery.

The distribution refers to the distance to the regional capitals in Italy. The data can also be considered

for delivery to other areas.

In regard to the referenced energy mix, the data used for the main raw materials refer to the average

European mix, except for the production of coatings characterized by the French mix, while data relating

to the Italian energy mix were used for the production process.

The impacts due to scrap incineration are evaluated. It can be hypothesized that the manufacturedproduct, at the end of its life, will end up in a refuse tip. The possibility of the complete release of

pentane into the atmosphere is considered in a precautionary way. However this is normally prevented

unless the material is broken, crumbled or smashed.

USAGE PHASE

For this phase, it is possible to consider the following:

The performance of the material, presented in Table 1, refers to its main function and is essentially

traced back to its heat resistance.

The 80 mm thick STIFERITE GT panels are inert, undissolvable and non-metabolizable. Therefore their

characteristics remain unchanged over time and their duration coincides with the structure where they

are installed.

The physical chemical characteristics of the pentane in the panel makes the gas permanently entrapped

inside the panel until its disposal (UNI EN 13165).

ADDED INFORMATION AND REFERENCES

THE COMPANY'S ENVIRONMENTAL MISSION

STIFERITE S.r.l. has a management system which is certified according to the voluntary Quality Standards

UNI EN ISO 9001. Wanting to make the environmental performance of its products accessible to the

public, STIFERITE has published this environmental declaration about the product according to the EPD

standard.

STIFERITE points to the following as some of the actions taken to improve its own environmental

performance:

the reduction of gas expenditure for heating thanks to an improved level of insulation of the

manufactured products, illustrated by the LCA studies conducted over recent years;

sending scrap to the thermal-exploitation systems with the recovery of energy happening outside of the

company's system. For this reason, it is not counted within the parameters of the present EPD.

A heat efficiency improvement of its products and the issue of products to the market that conduct less

heat so that they increase the insulation level of the manufactured products and consequently lower the

energy expenditure.

GLOSSARY

Acidification [AP]: phenomenon in which the atmospheric precipitation has a pH which is lower than

average. It damages forests and farming, as well as aquatic systems and manufactured products. It is

caused by the emission of SO2, NOx, and NH3, that are then included in the indicators of Acidification

Potential (AP), expressed by the g SO2 produced.

Heat Conductivity [ ]: It is the amount of heat transferred in a perpendicular direction to the surface of a

unit area, due to a temperature difference, in a time unit. The movement exclusively comes from the

difference in temperature. In easier terms, it is the ability of the substance to transmit heat. Heat

conductivity presented as *D] represents the amount established for a life of 25 years by 90% of the

production with 90% statistical reliability.

Ozone Depletion Potential [ODP]: depletion of the ozone layer, having the property of blocking theultraviolet sunlight component, due to especially reactive compounds that originate from Chloro-

fluorocarbons (CFCs) or Trichlorofluoromethane (CFM). The substance used as reference for the ODP

(Ozone Depletion Potential) is Trichlorofluoromethane, or CFC-11.

Greenhouse effect [GWP100]: Phenomenon in which the infra-red rays emitted from the earth's surface

following solar heating are absorbed by molecules found in the atmosphere and re-emitted as heat,

causing a global warming of the atmosphere. The indicator used is GWP 100 (Global Warming Potential

calculated for 100 years) that primarily includes the emissions of carbon dioxide, the main ingredient in

the greenhouse effect, in addition to other gases which have lower infra-red absorption, such as

methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), that are expressed based on theirabsorption of CO2 (g CO2 ).

Eutrophication Potential [EP]: Nutrient enrichment of waterways that provokes imbalances in the aquatic

ecosystem due to excessive development caused by the lack of nutritive limitations. Eutrophication

Potential (EP) primarily includes phosphorous and nitrogen. It is expressed in equivalent grams of oxygen

(g PO43-

).

Photochemical Ozone Creation Potential [POCP]: The production of compounds that are able to cause an

oxidization reaction that produces ozone in the troposphere. The POCP (Photochemical Ozone Creation

Potential) is mostly COV (Unstable Organic Compounds) and it is expressed in grams of ethylene (g C2H4).

Heat resistance [R]: It measures the ability of something to transfer heat in a certain direction, by a given

thickness and surface unit. It is inversely proportional to heat conductivity and directly proportional to

the thickness. The declared heat Resistance [RD] represents the value established for a life of 25 years

reported by 90% of the production with 90% statistical reliability.
