Authorised DealerRhino is a Sarda Group venture and the first rock mineral wool in India produced with electric smelting rather than a coke-fired cupola furnace — a change that cuts the embedded carbon of the product by roughly a quarter without giving up any of the performance that makes rock wool the default choice for fire, thermal and acoustic insulation.
Sankalp Electro Infra is an authorised dealer for the full Rhino range. We supply it into building envelopes, pre-engineered metal buildings, industrial plant and the same commercial and industrial sites where we install solar — because a roof that has been insulated properly does more for a building’s energy bill than any amount of generation bolted on top of it.

Product RangeResin-bonded boards
Precision-cut slabs for flat and large curved surfaces — roofs, external wall insulation, internal partitions, floors and ceilings, sandwich panels and fire barrier assemblies. Fire-safe to 1000°C with high dimensional stability.
80–160 kg/m³, 25–120 mm
Rock wool stitched to galvanised or stainless steel mesh for boilers, furnaces, process vessels, refinery pipework and machinery enclosures. Thermally stable to 780°C and built to take vibration and thermal shock.
Flexible rolls
Lightweight rolls for metal roof and wall systems, false ceilings and lightly loaded cavities — the fastest way to add a fire-rated thermal and acoustic layer over a large area.
Lamella boards & strips
Fibres oriented perpendicular to the face, giving high tensile strength across the thickness — used where the insulation itself has to carry load or bond to a facade system.
Bulk fill
Unbonded wool for packing irregular voids, expansion joints and fabricated components where a board or roll cannot follow the geometry.
Pre-formed sections
Pre-formed pipe sections for process and HVAC pipework. Availability is being brought online by the manufacturer — ask us for current lead times.
