UPVC (Unplasticized Polyvinyl Chloride) does not warp, rot, rust, or corrode. Unlike wooden frames that require periodic painting and are susceptible to termite damage, UPVC is virtually maintenance-free. It provides superior thermal insulation (keeping rooms cooler in summer) and cuts outside noise by up to 40dB when paired with double-glazed glass.

Yes! KST UPVC windows use multi-chamber internal hollow profiles combined with heavy-duty EPDM rubber gaskets that create an airtight perimeter seal when locked. When configured with Double Glazed Units (DGU, e.g. 5mm glass + 12mm air gap + 5mm glass), they attenuate street noise by up to 35-40 decibels and completely stop dust infiltration.

Absolutely. We exclusively use Grade-1 certified Toughened Safety Glass (12mm to 19mm) or Laminated Toughened Glass. This glass is 5 times stronger than regular window glass and resists severe human impact and high wind pressure. If accidentally broken under extreme force, it shatters into dull, blunt granular pieces that do not cause deep cuts.

For outdoor railings exposed to rain and humidity, we exclusively utilize SS 304 or marine-grade SS 316 fittings and spigots. These grades are immune to rust, peeling, and corrosion even in humid environments, ensuring your balcony railing looks pristine for decades.

UPVC windows are priced per square foot based on three main factors: 1) Frame configuration (sliding, casement, or tilt & turn), 2) Glass type (single clear, tinted, frosted, or double-glazed acoustic DGU), and 3) Color finish (standard architectural white vs. laminated wood-grain texture like walnut or golden oak).

After site measurement and design approval, standard orders take 5 to 8 business days for precision factory fabrication and toughening. Once on-site, a standard home installation is completed cleanly in 1 to 2 days without damaging your existing plastered walls.

Maintenance is exceptionally simple. For glass, wipe with a standard glass cleaner spray and microfiber cloth. For UPVC frames, use warm water with mild dish soap to remove dust. Lubricate the rollers and multi-point lock hardware with light machine oil once or twice a year to ensure whisper-silent operation.

Yes! We manufacture custom-sized pleated accordion nets, roller retractable screens, and magnetic flyscreens that can be retrofitted onto your existing UPVC, aluminium, or wooden window frames without altering the primary frame.

Yes. Our technical survey teams regularly travel across Firozabad, Agra, Tundla, Shikohabad, Etah, Mainpuri, Hathras, and Mathura. We provide free on-site measurements and consultation for residential and commercial projects.

We provide a 10-Year Comprehensive Warranty against discoloration, warping, and peeling on our UPVC window profiles, along with a 2-Year Replacement Warranty on sliding rollers, handles, and locking hardware.
