China, August 30, 2023 – United Insulation, a globally renowned exporter of building insulation materials, officially declared that its whole range of Glass Wool and Rock Wool products has passed the U.S. Green Building Council's (USGBC) strict audit, obtained LEED v4.1 compliance certification, and been enrolled into the USGBC's official materials database. That implies United Insulation has become one of the very few and among the first insulation material suppliers in China who can always contribute high scores to LEED Platinum Level Projects.

What are USGBC and LEED Certification?

USGBC, which is short for the U.S. Green Building Council, is the most authoritative green building certification organization in the world. This organization is headquartered in Washington D.C. in the USA. The LEED system, developed by the USGBC, was adopted in more than 190 countries and regions in the world, and it is currently the most widely recognized green building evaluation standard internationally.

The latest release of LEED v4.1 in 2025 greatly increases the bar for building materials, with significant impacts on insulation materials in the following credit categories:

Low-Emitting Materials

Environmental Product Declaration (EPD)

Health Product Declaration (HPD) and absence of substances on the Red List

Raw material sourcing transparency and responsible sourcing

Recyclable content and lifecycle carbon emissions

Materials that pass the USGBC review will appear in an official LEED materials database, from where architects and developers can reference their respective contribution scores.

Why do high-end projects worldwide consider USGBC/LEED certification the "gold standard" in green building?

North America: Over 90% of high-end commercial projects in the US and Canada require or have a preference for LEED certification.

Middle East: Dubai, Abu Dhabi, and Saudi Arabia's "Vision 2030" projects: All require LEED Gold or higher.

Asia Pacific: Singapore BCA Green Mark, China Three-Star Green Building, and Hong Kong BEAM Plus have high mutual recognition with LEED.

Europe: Although BREEAM and DGNB exist, a growing number of multinational corporations - including Apple, Google, and Microsoft - are increasingly requiring LEED Platinum for their worldwide headquarters and data centers.

By 2024, the total area of LEED-registered buildings in the world has surpassed 600 million square meters, and insulation materials contribute 8-15 points on average to the total score. USGBC-certified insulation products can often help a project obtain an additional 3-7 points directly, which will be an important factor in determining whether a project reaches "Gold → Platinum".

How does United Insulation achieve high scores throughout its complete product line?

After a very intensive 8-month audit by the third-party USGBC, United Insulation's glass wool and rock wool gained the following top-tier ratings in the LEED v4.1 system:

Complies with low-VOC material requirements; VOC emissions well below CDPH Standard Method v1.2

Provides Type III industry-average EPD + factory-specific EPD: carbon footprint as low as 78% of the industry average

Issues a complete HPD health product declaration with zero substances on the red list (California Prop 65, REACH SVHC)

Rock wool is manufactured with ≥45% recycled raw materials, and glass wool contains ≥70% recycled glass.

Obtained EUCEB + GREENGUARD Gold dual non-irritating fiber certification

This makes United Insulation currently the only insulation material brand in China that achieves high scores immediately upon application; our clients can thus choose our products for LEED projects and directly score points with almost no additional supporting documentation.

A Commitment to Global Green Building Clients

 "USGBC certification means we're not just selling insulation materials, but genuinely helping our clients achieve LEED points, secure projects, and command premium pricing," said the Sustainability Director of United Insulation. "From today onward, any LEED project choosing United Insulation can more easily and economically achieve Gold and Platinum certifications."

 Currently, the company has signed strategic supply agreements for 2026-2028 with several LEED Platinum projects from Gensler (USA), AECOM, EAG (UAE), and the Public Investment Fund (PIF) of Saudi Arabia.
