What is PVC & UPVC?

  • PVC (polyvinyl chloride) is a strong and lightweight plastic used in construction areas such as building or home designing; it is made softer and more bendable by the addition of plasticizers. If we do not add plasticizers then it is known as uPVC (unplasticized polyvinyl chloride) also known as rigid pvc or viny siding.uPVC is a superior material. Vinyl windows are made from rigid, impact-resistant polyvinyl chloride (PVC) with hollow spaces inside to make them resistant to heat loss and condensation.

Expansion & Contraction of Window profiles can lead to product deformation

Sunshine UPVC windows is manufactured from tropical formulation which makes it durable with minimal expansion and contraction

Aluminium has very high thermal expansion coefficient as compared to UPVC, leading to product distortion if not manufactured and installed appropriately.

Wood has inherent property to breathe / absorb moisture / expand & contract, eventually leading to distortion and gaps

Insulation from Heat

ShunshineUPVC windows provides superior insulation to your home from outside heat as UPVC is a poor conductor of heat

Aluminium (being a metal) is a good conductor of heat and therefore cannot provide insulation from heat

Wood is a poor conductor of heat, however improper sealing & bending can allow heat to pass

Low Maintenance

SunshineUPVC windows and doors require no painting, only routine cleaning

Aluminium windows and doors may require periodic maintenance over long periods of usage

Wooden windows need regular painting and polishing
