uPVC windows are the new normal. Yet for most homeowners in Hyderabad, the decision of which window to buy arrives in a rush — towards the tail end of construction, with the move-in date looming and the budget already stretched by surprises along the way. At Mason uPVC, one of the most common conversations our team has is explaining different window types, use cases, and how pricing actually works. This guide is for exactly that moment.
The Three Window Types You Need to Know
Windows come in many configurations, but most homes in South India work with three primary types: sliding, casement, and fixed. Understanding each one is the first step to making the right choice.
Sliding Windows: The Everyday Workhorse
Sliding windows, as the name suggests, move left and right on tracks. The most common variants are 2-Track (2T), 2.5-Track (2.5T), and 3-Track (3T).
- 2-Track (2T): Two panels of glass in an outer frame. Each panel slides, giving a maximum of 50% opening. The go-to for most standard openings between 3×3 ft and 5×5 ft.
- 2.5-Track (2.5T): Adds an extra track — typically used to fit a mosquito mesh panel alongside the two glass panels. Practical and popular for homes in Hyderabad and Visakhapatnam where ventilation matters year-round.
- 3-Track (3T): A less common choice, typically reserved for very large openings, especially sliding doors where the width or height exceeds 6 ft. Some homeowners opt for a third glass panel in the third track, extending the maximum opening to 66%. For large apertures where a 2.5T would suffice, the choice of a 3T often comes down to aesthetics — its heavier gauge sections simply look more substantial.
Casement Windows: The Aesthetically Superior Choice
If you care about how your home looks, casement windows deserve serious consideration. Inspired by the traditional outward-opening wooden windows of Indian homes, the uPVC casement window elevates that classic look with modern precision, weatherproofing, and longevity.
They are, however, more expensive than sliding windows — sometimes by 50% or more. The reason is straightforward: casement windows require more hardware. Every hinge, every multi-point handle, every mechanism that allows the sash to swing open and closed without sagging adds to the cost. But the reward is a window that can open to nearly 100% of its aperture — versus the 50% maximum of a sliding window.
A top-hung casement window is a variant worth considering for smaller apertures — it opens outward from the top, providing ventilation while keeping rain out. Particularly useful for bathrooms and compact spaces.
Fixed Windows: Façade First
Fixed windows do not open. Their purpose is visual — they bring light in, frame a view, and contribute to the exterior appearance of a building. Because they require minimal hardware compared to sliding or casement variants, they are also the most affordable type.
Combinations of two window types — say, a fixed panel flanking a sliding unit, or a casement beside a fixed light — are common and often the most elegant solution for achieving both function and aesthetics.
Why Can’t a Fabricator Just Give You One Price?
This is one of the most frequent questions homeowners ask. The answer comes down to material consumption per square foot, and it is less intuitive than it sounds.
That means the price per square foot of a small fixed window can be higher than that of a large sliding window, even though sliding profiles cost more per linear foot. The math of material consumption per unit of output changes the equation entirely. Add in hardware, glass specification, mesh requirements, and installation complexity — and it becomes clear why a single quoted rate is rarely meaningful until the actual openings are measured.
A Quick Reference Before You Decide
- Standard room windows (3×3 ft to 5×5 ft): 2T or 2.5T sliding is usually the right answer — functional, economical, and widely available.
- Living room or bedroom focal windows: Casement windows, if the budget allows. The opening quality and visual presence are hard to match.
- Large sliding doors (6 ft+ widths): 3T sliding, with or without a third glass panel depending on the aesthetic intent.
- Façade panels and stairwell lights: Fixed windows — clean, cost-effective, and low-maintenance.
