LEED v4.1 By Credit Category

Thin brick weighs less than traditional brick and is designed to be thin, which saves energy and natural resources. Specifying METROBRICK® will help earn credits in green building certifications for LEED v4.1.

METROBRICK® & LEED V4.1 Overview

Please Note: The following are generalizations only. We do not currently have third party certification for some of these specific LEED credits.


Building Life Cycle Impact Reduction METROBRICK products have a 60-plus-year lifespan and can last the life of the building.

Product Disclosure {Source of Raw Material} | METROBRICK products contain pre-consumer recycled waste material. Additionally, 92% of all raw materials are extracted within a 50-mile radius of the manufacturing facility.

Product Disclosure {Material Ingredients} | METROBRICK has a Material Ingredient Disclosure verified by WAP Sustainability Consulting.

Product Disclosure {Environmental Product Declarations} | METROBRICK has taken part in an industry-wide EPD for ceramic products.

Construction and Demolition Waste Management | METROBRICK products are inert material after firing and can be reused or reclaimed as fill or roadbed material. The product’s sizing is such that there is little job site waste of material. The packaging material is recyclable.


Low Emitting Materials | Ceramic products are cited as an “inherent non-emitting source” for this credit. METROBRICK may be used for this credit without testing.

Construction Indoor Air Quality | METROBRICK products are VOC- free and are resistant to mold and mildew.

Indoor Air Quality Assessment | METROBRICK products are inert. They are VOC-free and formaldehyde free.

Thermal Comfort | The thermal mass of METROBRICK products allows them to aid in creating a more consistent indoor environment.


Integrative Process | METROBRICK Thin Brick used as part of an installation wall system can positively impact other building systems. The wall system that includes METROBRICK® should be evaluated as part of a project’s integrative analysis.


Certified Multi-Attribute Products & Materials | Green Squared is included in this pilot credit. METROBRICK G2 products meet the criteria of this credit because METROBRICK® is part of an industry-wide EPD.


Optimize Energy Performance | The thermal mass of METROBRICK products may help in the moderation of indoor temperature swings.

Environmental Documents

The materials and processes used in manufacturing METROBRICK Thin Brick align with third-party certifications on sustainability, including Green Squared®, Environmental Product Declaration (EPD) and Health Product Declaration (HPD).

Green Squared Certificate

METROBRICK products are Green Squared Certified, meeting criteria for product characteristics, manufacturing /raw material extraction, end of product life management, progressive corporate governance and innovation.

Environmental Product Declaration (EPD)

METROBRICK has taken part in an industry-wide Environmental Product Declaration – EPD. The EPD reports the environmental footprint of North American-made ceramic products across all major impact categories.
