What Is NusTherm™?

A practical coating solution for glass that's letting in too much heat

NusTherm™ is a glass heat reduction coating product line under Nusfun. It is designed for selected retrofit applications where existing windows, glazed roofs or curtain wall systems contribute to indoor heat gain, cooling load and comfort issues.

The coating is applied to suitable glass surfaces as part of a practical building upgrade pathway. It may help reduce solar heat transmission while maintaining natural light and visibility, subject to glass type, site conditions and application quality.

Key Benefits

A practical pathway for glass-related heat reduction

Reduce Solar Heat Gain

Designed to help reduce heat entering through selected glass surfaces, supporting improved indoor comfort in suitable applications.

Maintain Natural Light

Positioned for projects where clients want to improve thermal comfort without heavily changing the appearance of existing glass.

No Glass Replacement

Can support retrofit projects where replacing existing glazing may be costly, disruptive or difficult to justify.

Support Energy Upgrade Discussions

For buildings with high cooling demand, may form part of a broader energy-efficiency upgrade strategy.

How It Works

How NusTherm™ Works

Glass heat gain is influenced by solar radiation, glass type, orientation, shading, building design and air-conditioning operation. NusTherm™ is intended to reduce part of the solar heat transmission through suitable glass surfaces — combining a durable Protective Layer with an advanced Performance Layer — helping project owners consider a less disruptive retrofit pathway.

  1. Step 1 — Initial Discussion

    Understand the building type, glass area, heat issue, project goals and decision pathway.

  2. Step 2 — Site Assessment

    Review glass type, orientation, access, safety, existing shading and expected usage conditions.

  3. Step 3 — Pilot Area

    Where appropriate, apply a small test area to confirm appearance, handling and site suitability.

  4. Step 4 — Proposal

    Prepare a project-specific recommendation. Any energy-saving or ROI estimate should be treated as indicative unless supported by measured data.

  5. Step 5 — Application

    Application should be completed by trained or approved partners following Nusfun guidance.
