What aluminium alloy is used for doors and windows in India?

The correct alloy for architectural aluminium doors and windows in India is 6063-T5, which offers the ideal balance of extrudability, strength, and corrosion resistance. This alloy is specified in IS 1285 and is used for all our door, window, and curtain wall profiles. It accepts anodising, powder coating, and PVDF finishes.

What is the difference between sliding and casement aluminium windows?

Sliding windows operate on a horizontal track and are suitable for most residential and commercial applications. They are cost-effective but have lower weather sealing performance. Casement windows are hinged and open outward, offering superior weather sealing, better ventilation control, and higher acoustic performance. Casement systems are preferred for ECBC-compliant buildings and high-rise facades.

Are your aluminium systems ECBC compliant?

Yes. Our double-glazed aluminium window and curtain wall systems can be configured to meet ECBC 2017 and ECBC-R 2021 U-value and SHGC requirements. We provide thermal performance documentation including U-value calculations and glass specifications for energy compliance submissions.

What finishes are available for aluminium doors and windows?

We supply aluminium systems in powder coat (any RAL colour), anodised (natural, bronze, champagne, black), and PVDF wood-grain and solid finishes. Powder coat is most common for residential projects. PVDF is specified for high-rise facades due to its superior UV and weather resistance over a 20-year lifecycle.

Can aluminium folding doors be used for large openings?

Yes. Our aluminium folding door systems can accommodate openings from 2.4m to 6m wide and up to 2.7m high in standard configurations. For larger openings, structural engineering input is required. The systems are suitable for residential living spaces, hotel lobbies, restaurants, and commercial facades.

6063-T5 Aluminium — Why It Is Specified for Large Projects

Aluminium alloy 6063-T5 is the international standard for architectural aluminium extrusions. It provides the optimal combination of extrudability, surface finish quality and structural performance for door and window applications. The T5 temper designation indicates artificial ageing after extrusion — producing a harder, more dimensionally stable profile than T1 or untempered alloys.
