Low-E Glass Options for Aluminium Doors and Windows
Low-emissivity coatings can be considered when solar heat control or insulated glazing performance is part of the project brief. The coating and glass build-up must be selected with the frame, orientation and visual requirements.
What to confirm before selection
| Project objective | Clarify whether the priority is solar heat control, thermal insulation, daylight, appearance, privacy or a combination. |
|---|---|
| Orientation and shading | Review facade direction, external shading and the amount of direct sun reaching each opening. |
| Glass build-up | Confirm whether the coating sits within a compatible IGU or another approved project-specific glazing configuration. |
| Appearance | Discuss visible light, colour and reflectance expectations before final approval. |
| Frame and installation | Pair the glass with a compatible frame, seals, hardware and installation detail; glass alone does not define total performance. |
Final glass and frame selection remains subject to opening dimensions, profile compatibility, site exposure, structural and safety requirements, and the approved project specification.
Common questions
Is Low-E glass the same as tinted glass?
No. A Low-E coating and a body-tinted pane are different specification choices, although a project may combine compatible options.
Can Low-E glass be used in sliding doors and windows?
Potentially, subject to the selected frame profile, IGU thickness, panel weight, hardware capacity and approved glass build-up.
How should an option be selected?
Start with the opening, orientation, room use and performance objective, then confirm a compatible glass and aluminium system before quotation.
