Retractable roofs · Telescopic & sliding

Bays that slide into each other.

A telescopic roof is a row of arched bays, each slightly smaller than the next, that slide on tracks and nest together at one end. Closed, it is a full vault over the space. Open, it takes up the length of a single bay or two.

What is a telescopic retractable roof?

A telescopic retractable roof is a set of arched bays of stepped size that slide on floor or eave tracks and nest inside one another to open. It suits pools, terraces and openings where the parked roof has to take up as little length as possible.

How it is built

The frame, the cover, the drive.

  1. 01

    Each bay runs on its own track on steel rollers. Bays step down in size so they can pass inside one another and park in a short stack.

  2. 02

    Manual telescopic roofs run on a chain drive with rack and pinion, with a manual lock and rubber buffers at the ends. Motorised versions add a drive and limit switches.

  3. 03

    Every system is run through its full travel on our factory floor before it leaves. A bay that binds is far cheaper to find in the works than on a roof.

Where it works

  • Swimming pool enclosure
  • Villa pool deck
  • Terrace and sit-out
  • Industrial loading bay
  • Nursery and greenhouse
  • Covered walkway that opens

Typical specification

What goes into it. Confirmed at survey.

Cover
Polycarbonate with UV-protected face, or fabric bays
Track
MS C-channel or aluminium track, steel rollers
Operation
Manual chain drive with rack and pinion, or motorised
Ends
Manual lock and rubber buffers; limit switches when motorised
Warranty
One year on the complete system, in writing

The final configuration, frame sizes and drive are set at detailed engineering for your site, wind and use. Cost: most installed projects fall between ₹280 and ₹2,500 per sq ft plus GST; what moves the number.

Before you order

Settle these at the survey and the roof will work for years.

  • Travel distance

    Manual or motor is decided by how far the bays travel and how often, not by the area.

  • Parking length

    The nested stack still needs a clear length at one end. Plan it with the pool or deck layout.

  • Heat and yellowing

    Polycarbonate gets hot under a Delhi summer and yellows without a UV co-extruded face. Check the face is named on the quote, and plan ventilation.

  • Track level

    Floor tracks need a level, true base. On an existing deck we survey it first.

FAQ

Common questions.

All questions

  1. It is one of the most common uses. Closed, it keeps leaves and rain out and holds some warmth; open, the pool is fully outdoors. Plan ventilation, because a closed polycarbonate vault gets hot in summer.

  2. We run each system through its full travel in our works before it goes to site, then again after installation at commissioning.

  3. Not simply. The drive, track and controls are designed differently, so decide at the start.
