Roofs that open.

A roof whose cover, fabric or polycarbonate, moves on tracks or rails so the space underneath can be closed against sun and rain or opened to the sky. The frame and foundations stay fixed; only the cover bays move.

Most installed projects fall between ₹280 and ₹2,500 per sq ft plus GST, and a moving roof sits higher in that range than a fixed one of the same area. The number of moving bays, the span, how often it opens, the power and safety chain, the membrane and the drainage decide where yours lands.

Manual suits a balcony or small pergola you will not move every day. Motorised is worth it on a large terrace or courtyard, or for anything opened daily. It needs a power point at the drive, and adding a motor later is not simple.

Fabric is lighter, cooler underneath, quieter in rain and folds compactly. Polycarbonate gives more daylight but gets hot in summer, is louder in rain and needs a UV-protected face. It is a structural choice made early.

Closed, yes from above: the cover sheds rain to gutters and downpipes, and the roof is designed for your site wind. It is weather cover, not a sealed room, so air moves at the edges.

A motorised roof stays where it is. If your site loses power often, ask for a manual override or a backup supply at design stage.

A roof or canopy made of a fabric membrane that is pulled tight between steel masts, frames and cables. The membrane is curved in two directions, a saddle or cone shape, and that curvature plus pre-tension is what makes it stiff. It weighs a fraction of a concrete or metal roof and can span large areas with few columns.

Most installed projects fall between ₹280 and ₹2,500 per sq ft plus GST. Where yours sits depends on the membrane grade, the span and shape, the steel and foundations, site access and the total area. A PVC car parking shade sits at the economical end; a large clear span in PTFE is well above it. We quote each project after a site survey, with steel, membrane, foundations and installation as separate lines.

PVC-coated polyester has a design life of roughly 15 to 20 years, longer with a PVDF top coat. PTFE-coated fibreglass lasts 25 to 30 years and beyond. Our membrane warranty runs up to 15 years depending on the grade.

Yes. Architectural membranes are UV-stabilised and waterproof, and they handle heat better than metal sheet because they reflect much of the sun instead of radiating it down. The structure is designed for the wind of your town and shaped so monsoon rain runs off rather than ponding.

Wind is the load a tensile roof is designed around. Our standard design basis is 150 km/h, checked against the figure IS 875 Part 3 gives for your exact site and raised wherever the code requires more. Uplift is checked as its own load case, and foundations are sized from it.

Coated membranes are fully waterproof and the panels are welded, not stitched, so the seams are watertight too. Every roof is given enough curvature and fall for water to run to planned drainage points instead of collecting on the fabric.
