ISO 14025. EPDs rely on Life Cycle Assessment (LCA) to provide information on a number of environmental impacts of
products over their life cycle. Exclusions: EPDs do not indicate that any environmental or social performance benchmarks
are met, and there may be impacts that they do not encompass. LCAs do not typically address the site-specific
environmental impacts of raw material extraction, nor are they meant to assess human health toxicity. EPDs can
complement but cannot replace tools and certifications that are designed to address these impacts and/or set
performance thresholds – e.g. Type 1 certifications, health assessments and declarations, environmental impact
assessments, etc. Accuracy of Results: EPDs regularly rely on estimations of impacts, and the level of accuracy in
estimation of effect differs for any particular product line and reported impact. Comparability: EPDs are not comparative
assertions and are either not comparable or have limited comparability when they cover different life cycle stages, are
based on different product category rules or are missing relevant environmental impacts. EPDs from different programs
may not be comparable.

Manufacture

Processed glass and aluminum extrusions are manufactured within the same manufacturing facility in Barranquilla,
Colombia and are internally transported to the ES Windows facility for final fabrication into window products. Once all
products have undergone quality inspection, the aluminum extrusion is cut to customer specifications and the frame is
assembled including the addition of a gasket and silicone sealer. The finished window product is then packaged and
distributed to the customer.

Environment and Health During Manufacturing

ES Windows is committed to reducing its environmental impact and to the health and safety of its employees. Through
their core values, ES Windows places a responsibility to be accountable for their actions and interactions with the
environment and stakeholders. This is emphasized in the code of conduct which includes respecting human rights and
the rights of employees in addition to protecting the environment and surroundings through sustainable production
processes. To reduce energy consumption, ES Windows has installed a solar panel system to offset energy needed
from the local grid. For the efficient use of water, saving devices are used, water consumption is monitored, leaks are
analyzed and repaired, and awareness campaigns are utilized to make employees aware of sustainable objectives.

Product Processing/ Installation

ES Windows’ products should be installed by qualified contractors, adhering to best industry standards and according
to all applicable building codes in the local jurisdiction. The installation and use stages are outside the scope of this
EPD.

Packaging

Shipments of window products are delivered to customers at the project site in cardboard packaging. ES Windows
requests that customers dispose of the packaging materials in the appropriate disposal/recycling streams in
accordance with their local guidelines.

Conditions of Use

ES Windows’ products are intended primarily for construction applications for commercial and residential building
projects.

Environment of Health During Use

There is no harmful emissive potential. No damage to health or impairment is expected under normal use
corresponding to the intended use of the product.

Reference Service Life

This EPD does not cover the product use phase and therefore makes no specific claim as to the typical reference for
service life.

Extraordinary Effects

Project, Fixed and Single Hung Window According to ISO 14025 & EN 15804
Windows and Doors

Mechanical Destruction: No danger to the environment can be anticipated during mechanical destruction.

Re-use Phase

Reuse or recycling of processed glass and aluminum framing should be considered where feasible.

Disposal

ES Windows’ products are not considered a hazardous material, so it may be disposed via typical, non-hazardous
waste stream classifications and disposable routes; nevertheless, ES Windows encourages the repurposing of
products due to their ease of reuse and reuse versatility. When not suitable for reuse, recycling options are typically
available and should be investigated rather than introducing the product to the waste stream. Aluminum is 100%
recyclable and should be recycled where outlets are available. Glass is considered a non-combustible material and is
not suitable for waste to energy.

Estimates and Assumptions

The major assumptions for the development of this EPD are listed below:

• Ecoinvent v3.5 database with cut-off allocation processes is used as the primary database source for
conducting the LCA in SimaPro.

• Certain raw materials are not entirely modelled but selected from the ecoinvent v3.5 database.
• Certain materials, for which the Safety Data Sheet (SDS) was not provided, or which had missing components,

were modelled as proxy chemical compounds in approximation with similar products and/or best available
practices.
• The LCA results in this EPD are for the Project Window as this product has the highest environmental impact
amongst other windows under consideration for developing this EPD. This is therefore considered to be
representative of other window products under consideration since its impacts are on the higher spectrum of
these product lines.

Cut-off Criteria

Processes whose total contribution was less than 1% of the product mass or contribute less than 1% to all considered
impact categories were excluded.

All material flows that exit the system and whose total contribution was more than 1% of the total impact in that impact
category were included.

For the processes within the system boundary, all available energy and material flow data have been included in the
model.

Background Data

Primary data was collected from the manufacturer from the 2018 calendar year, representing the latest data available.
Each dataset used was taken from SimaPro databases, either ecoinvent v3.5, US-EI 2.2 or US LCI. These databases
are widely distributed and referenced within the LCA community and are either partially or fully critically reviewed.

Project, Fixed and Single Hung Window According to ISO 14025 & EN 15804
Windows and Doors

Data Quality

Throughout the creation of the LCA models, a variety of tests and checks were done to ensure the highest of quality of
the completed analysis. Checks include an extensive review of the model and the background data.

To ensure precision, completeness, consistency and representativeness of the data, first-hand industry data and
reliable LCI data from ecoinvent v3.5, US-EI 2.2 and US LCI databases were used. Processes and data used are
representative of the global geographical range and the standard or best available practices.

Period Under Review

First-hand industrial data collected from ES Windows is representative of ES Windows’ production for the 2018
calendar year. However, data used from the LCI databases in SimaPro has a wide temporal range from 1979 to 2020.

Allocation

Unit allocation was used to determine the manufacturing inventory for window and door products. This methodology
was selected because the manufacturing process is primarily an assembly process and does not vary significantly
across products of different type, dimensions, and mass.

Comparability

A comparison can only be possible if all data sets to be compared were created according EN 15804 and the building
context, respectively the product-specific characteristics of performance, are considered.

Results

Results are reported based on characterization factors from the US EPA Tool for the Reduction and Assessment of
Chemical and Other Environmental Impacts (TRACI 2.1 impact categories). Additionally, impact categories taken from
the University of Leiden (CML) methodology are reported to facilitate the use of this EPD outside of North America.

LCA results are presented per the declared unit (1.5m x 1.3m). Note that, at this point, the reported impact
categories represent impact potentials, i.e., they are approximations of environmental impacts that could occur if the
emissions would (a) follow the underlying impact pathway and (b) meet certain conditions in the receiving environment
while doing so. Life Cycle Impact Assessment (LCIA) results are therefore relative expressions only and do not predict
actual impacts, the exceeding of thresholds, safety margins, or risks.

LCA Interpretation

It is evident from the results that raw material extraction (A1) is the most impactful stages across most of the impact
categories in the life cycle of Project window products.

Though not the primary driver of impacts, the manufacturing (A3) stage also has a considerable impact across a few
impact categories.

Amongst raw materials, the anodized aluminum trim and the processed glass drive the raw material impacts across all

Project, Fixed and Single Hung Window According to ISO 14025 & EN 15804
Windows and Doors

impact categories.

For the manufacturing process, electricity usage has the highest contribution to the manufacturing impacts across
most of the impact categories. Use of support materials also has a significant contribution to the manufacturing
impacts.

Since the cut-off methodology was used for this LCA, the end-of-life impacts (C4) are positive for this product and
recycling offsets were not considered for recyclable materials.
