FAQ — LOW‑E GLASS

1. What is Low‑E glass?

Low‑E (Low‑Emissivity) glass features a special coating that reduces radiant heat transfer while allowing visible light transmission.

2. How does Low‑E glass save energy?

Low‑E coatings reflect radiant heat, improving insulation (lower U‑value) and reducing solar heat gain (SHGC), which lowers heating and cooling loads.

3. Can Low‑E glass be used in insulated glass units (IGUs)?

Yes. Low‑E glass is most effective when incorporated into IGUs, where thermal performance and comfort are maximized.

4. What is the difference between hard coat and soft coat Low‑E?

Hard coat Low‑E is durable and suitable for monolithic applications, while soft coat Low‑E offers higher thermal performance within insulated units.

5. Does Low‑E glass reduce natural light?

No. Low‑E glass maintains high visible light transmission while controlling heat transfer.

6. Is Low‑E glass suitable for all climates?

Yes. Low‑E glass can be tailored with specific coatings and configurations for both hot and cold climates.

7. Can Low‑E glass be tempered or laminated?

Yes. Low‑E glass can be combined with tempered or laminated safety treatments depending on project requirements.

8. How do I clean Low‑E glass?

Use mild, non‑abrasive glass cleaners and a soft cloth. Avoid harsh chemicals, especially on coated surfaces.

9. Does Low‑E glass improve indoor comfort?

Yes. By reducing heat transfer and controlling solar gain, Low‑E glass helps maintain more stable indoor temperatures and reduces glare.
