| Tendency | Prompt uPVC | Wood | Aluminium |
|---|---|---|---|
| Surface Quality | It is maintained throughout it’s useful life | Requires timely maintenance | Anodizing wears out |
| Thermal Insulation | Very good, Heat losses are reduced due to wider profile depth & multi chamber section. | Fair | Being a metal it has a poor thermal insulation, and high thermal conductivity. |
| Fire Properties | Non-combustible | Poor | Good |
| Durability | Excellent | Fair | Poor |
| Corrosion & Termite Resistant | Good | Poor | Poor |
| Chemical Resistant | No effect | Rots | Corrodes |
| Warping | Will not warp | Can warp | Can warp |
| Maintenance Free | Good | Poor | Fair |
| Acoustic Insulation | The multi chamber sealed cavities and welded corners offers excellent acoustic insulating properties. | The mechanically joint corners render very poor result from acoustic insulation angle. | Fair |
| Dimensional Accuracy | They are factory produced on sophisticated machine hence offers uniform quality control. | Fabricated locally and manually, hence poor quality and non-uniformity. | Fair |
