uPVC vs Steel Windows: A Practical Comparison

Many older Coimbatore homes still have steel windows, and replacing them is one of the most common jobs we do. Here's how uPVC compares with the steel frames it usually replaces.

Rust and corrosion

Steel's central weakness is rust. Once the protective coat is breached, corrosion spreads, stains the wall, and eventually seizes the moving parts. uPVC cannot rust at all, which is the main reason homeowners switch.

Insulation and sealing

Steel conducts heat and old steel windows rarely seal well, letting in dust and noise. uPVC insulates better and, with proper gaskets, seals tightly against dust and rain — a noticeable change in a busy or dusty location.

Replacing steel with uPVC

This is straightforward work: we measure the existing opening and make the new uPVC unit to fit it. Most homeowners notice the difference immediately in how quiet and dust-free the room becomes.

Questions

Frequently asked

Why replace steel windows with uPVC?

Mainly to be rid of rust, and to gain better sealing against dust and noise. Steel windows also tend to jam as they corrode; uPVC moving parts run smoothly for years.

Is replacing old steel windows difficult?

No — we measure the existing opening and build the new unit to fit. It's routine work for us in older homes.

Will uPVC keep out dust better than my old steel windows?

Almost always yes. Old steel frames rarely seal well; uPVC gaskets close the gaps that let dust in.
