Aluminum vs uPVC Doors: Which is a Better Choice for Homes in Kerala?

If you’re building or renovating a home in Kerala, you already know one truth: our climate doesn’t spare anything. Between the heavy monsoons, salty coastal air, and humid summers, choosing the right door material is more than a style preference, plus it’s a long-term investment.

As one of the trusted aluminum and uPVC doors and windows manufacturers in Kerala, we get one question every single day: “Should I choose aluminum or uPVC windows and doors? Which is better for my home?”

The answer is, both aluminium and uPVC have distinct advantages for homes in Kerala, shaped by the region’s humid climate, coastal exposure, and modern architectural trends. This blog will guide you through the key differences and help you decide.

Kerala’s climate is tough on building materials. We sit right in the hot-humid zone, meaning months of heavy rain, constant moisture, and salty air drifting in from the coast. So choosing the wrong material would be long term liability.

Moisture: The long monsoon season means materials are wet for months. Wood absorbs this water, swells, and rots.

Salinity: Kerala has a long coastline. Salt air accelerates rust (oxidation) in metals.

Humidity and Bio-threats: High humidity creates the perfect breeding ground for termites and mold.

Now let’s see how uPVC and aluminium handle this:

uPVC doors resist corrosion, termites, and rust - making them ideal for areas with moisture problems and coastal exposure.

Aluminum doors are robust, strong, and now often come powder-coated or anodized, which prolongs life and resists corrosion, especially in coastal areas. However, cheaper uncoated aluminum can corrode over time if maintenance is ignored.

Maintaining indoor temperature and comfort is a top priority for Kerala homes.

uPVC doors excel in thermal insulation, keeping interiors cooler in summer and preventing heat ingress. This translates into lower electricity bills and greater comfort during Kerala’s hot, humid months.

Aluminum doors are naturally less insulative but modern designs with thermal break technology offer better insulation than older profiles.

Your choice of doors affects your home’s aesthetics.

uPVC doors offer a variety of designs, finishes, and colours. They can be crafted to mimic wood grain for traditional homes or sleek for modern builds.

Aluminum doors provide slim, elegant profiles and enable larger glass panels for a contemporary look, ideal for modern Kerala homes seeking clean lines and maximum light.

Low maintenance is a major need for busy homeowners.

uPVC doors require very little upkeep—just regular cleaning and minimal risk of discoloration, rust, or decay.​

Aluminum doors also offer durability and require little maintenance if finished properly. Uncoated aluminum in coastal areas may need more frequent attention.

Your budget and sustainability goals influence your choice.

uPVC doors are generally more affordable while still offering significant benefits in insulation and durability.

Aluminum doors are typically more expensive upfront, especially with premium finishes or thermal accessories, but provide long-term value and recyclability.

So, which door material truly deserves a place in your Kerala home?
Honestly, it depends on what you value most.

If your priority is better insulation, minimal maintenance, and long-term stability in humid or coastal regions, uPVC doors are the smarter choice. Their performance in Kerala’s weather is unmatched — especially options like our Wooden Finish uPVC Doors, which give you the warmth of wood without the swelling, rotting, or maintenance headaches.

On the other hand, if you prefer a more modern aesthetic with slimmer profiles and large glass areas, aluminium doors shine. Go for high-quality, thermally broken Aluminium Casement & Sliding Doors with premium powder-coated or anodized finishes to ensure excellent durability in Kerala’s climate.

For most homeowners, uPVC doors offer the most balanced solution — exceptional weather resistance, thermal comfort, sound reduction, and zero maintenance at a competitive price.

But for modern villas, apartments, and premium architectural projects, aluminium doors—especially Aluminium Casement & Sliding Doors—deliver a clean, contemporary look with outstanding strength.
