Greenplast windows and doors manufactured with uPVC, as a substitute, are best alternative for wood and aluminium because of their features like high structural strength, high energy efficient, lightweight, recyclable, termite proof, washable, dust proof, sound proof, corrosion and UV resistant. The longevity and superior quality of this material has been conclusively proved for almost 40 years.
Together with Kommerling, German Technology & Profile Partner, Greenplast window systems are designed as per Indian tropical conditions. Koemmerling is the brand with a tradition within the Profine Group, having started the extrusion of window profiles since 1967. Besides aesthetic viewpoints, these include peak technical & physical performance values and an extremely long life while at the same time requiring minimum care and maintenance.
| Particulars | Wood | Steel/ Aluminium | uPVC Windows |
|---|---|---|---|
| Maintenance | Require regular Painting & Polishing | Nil | Nil |
| Corrosion | Termite & Rot Attacks | Corrosive | No Corrosion or Termite Attacks |
| Weather Proofing | Leaks & Droughts | Leaks, Droughts & Wind Rattle | No Leaks, No Droughts, No Rattle, Self- Draining |
| Sound Proofing | Average Subject to Wind Noise | Poor Subject to all noises | Excellent Sound Proofing |
| Ease of Operation | Difficult if not maintained | Not Smooth | Smooth/ Easy Gliding Action |
| Insect Screen | Optional | Optional or Included | Included with Sliding, Many options |
| Warranty | None | None | 10 years |
| Termite Proof | Affected by termites, extreme un-repairable damages to wood | Affected by Fungi | No Harm |
| Water Resistance | Water Causes extreme un-repairable damages to wood | 80% - 90 % | No Harm |
| Surface Quality | Requires regular up keeping | Anodizing wears out and Corrosion sets it. | The surface quality is maintained throughout its useful life. |
| Thermal Insulation | Fair | Poor being a metal it has a poor thermal insulation, and high thermal conductivity. | Very good, Heat losses are reduced due to wider profile depth & multi chamber section & Low K value. |
| Fire Properties | Poor | Excellent | Excellent |
| Dimensional Accuracies | Fair | Poor, they are fabricated locally, hence poor quality and non uniformity | Excellent, they are factory produced on sophisticated machine hence offer uniform quality control. |
| Conservation of Energy | - | Require 7.5 times the energy than that required to manufacture UPVC. | Excellent |
| Preservation of Natural Forest Wealth | Poor | Excellent | Excellent |
| Durability | Good | Good | Much stronger due to steel reinforcement profile. |
| Warping | Can Wrap | Can Wrap | Will not warp, last for a life time. |
