Aluminium or uPVC Windows: Which One Is Right for Your Home?

• Pro: It’s durable

Aluminium windows are resistant to rust, are weatherproof and do not swell or crack when exposed to heat. However, these windows may not be very suitable for coastal areas as aluminium has a tendency to corrode and discolour due to oxidation in the presence of salt-laden air. In conducive conditions (away from salty air or spray or with suitable protective paint), the lifespan of aluminium windows is more than 45 years.

• Pro: You get it in multiple colours and finishes

Aluminium windows are available in various styles like casement, fixed, sliding and tilt-and-turn windows. Most windows can be fabricated as single-, double- or triple-glazed units.

The aluminium sections are finished with a durable powder coating or anodising (coating a metal through electrolysis) because aluminium does not take to normal paint easily. The powder coating imparts an attractive look and does not discolour, corrode or peel easily. One can get the paint coating in any colour and it is available in various finishes like like satin, gloss or matte.

Tip: Note there are more colour options available in aluminium than uPVC windows. Also, make sure you go for a powder coating with high UV resistance otherwise the windows may discolour after long exposure to the sun.

• Con: …and requires periodic maintenance

Although aluminium is a hard-wearing material, it may require some periodic maintenance. These windows tend to rattle in high winds, which could loosen their hardware, such as screws. Ensure that the screws are tightened regularly; also they may need a fresh coat of paint after a few years.

uPVC WINDOWS

• Pro: It’s strong and can take tough conditions

uPVC is a strong and durable material. It comprises uPVC multi-chambered air-filled sections known as profiles that are reinforced internally with galvanised steel sections to strengthen them. It is resistant to UV rays. It does not rust, corrode or flake and is also suitable for coastal areas (unlike aluminium, which may corrode or discolour).

• Pro: It allows high security

Multiple-lock systems and shootbolt locks can be successfully installed in uPVC windows to provide enhanced security.

• Pro: uPVC is easy to maintain

uPVC doors and windows are easy to maintain; routine cleaning includes a quick wipe with a damp cloth. For deeper cleaning a light solution of soapy water is sufficient. Additionally, uPVC windows are designed with a built-in rain track with a slope that does not allow water to seep indoors.

Most uPVC window systems come with good hardware that ensures ease of operation and swift movement of sliding windows on rollers.

• Pro: It provides good thermal insulation…

Double- and triple-glazed uPVC windows are a great solution to achieve an energy-efficient home. uPVC is a poor conductor of heat and does not allow any heat loss or heat gain within the interiors.

Pro tip: This is one of the most important aspects that differentiates uPVC from aluminium windows. Note that the windows are meticulously sealed with sealants and rubber gaskets that close off any air gaps present.

• Pro: …and blocks out noise

If you want a soundproofed home, install insulated double- or triple-glazed uPVC windows. They work as effective acoustic barriers that significantly cut down noise from the outdoors. These windows are recommended for homes that are located near main roads with heavy traffic.

• Con: It has a shorter life

uPVC is primarily a synthetic plastic polymer, which has an average life span of about 25 to 30 years. This is less than aluminium windows. Also, some homeowners don’t find uPVC attractive because of its plastic look.
