A quoted slab rate is not comparable until thickness, density, facing, area, GST, freight and unloading are placed on the same basis. By the end, you will be able to convert offers to ₹/m² and ₹/m³, specify the product correctly, assess installation requirements and choose a supplier without confusing a rigid slab with a roll or mattress.
Key takeaways
- Budget ₹150–₹650 per square metre for common 25–50 mm slabs.
- Request density, thickness, facing, thermal conductivity, and fire-test details.
- Seal joints, avoid compression, and protect slabs from water during installation.
- Check batch numbers, packaging, test reports, and delivery damage before acceptance.
What resin bonded slabs cost in Delhi
A resin bonded slab price in Delhi is roughly ₹150–₹650 per square metre for common 25–50 mm products; dense, thick or specially faced slabs can exceed this range. Treat this as a screening figure, not a firm offer.
GST, cutting, packing, freight and unloading can add substantially, while low-density slabs consume truck space despite their low weight.
Convert every quote to a delivered, tax-inclusive price per usable square metre. For a per-slab quote, divide the slab price by length in metres × width in metres. For a cubic-metre quote, multiply the rate by the slab thickness in metres.
Divide a package or roll price by its usable area after allowing for damaged or unusable material.
| Offer | Stated terms | Comparable result for 100 m² |
|---|---|---|
| A | ₹360/m², plus 18% GST, ₹8,000 freight | ₹50,480 delivered, or ₹505/m² |
| B | ₹425/m², GST, freight and unloading included | ₹42,500 delivered, or ₹425/m² |
Before comparing, make both offers use the same fibre type, density, thickness, facing and area. Ask for slab length and width, thickness in millimetres, density in kg/m³, thermal conductivity in W/m·K, operating-temperature range, water-repellent treatment, fire classification, facing and dimensional tolerance.
Confirm resin treatment, number of slabs per pack, batch or manufacturing date, minimum order, delivery lead time and replacement terms. “Per slab” means nothing until those dimensions are stated.
The specification sheet to request before placing an order
A quotation is comparable only when it identifies the exact slab, not merely “resin bonded insulation.” If you plan to buy resin bonded slabs in Delhi, request these technical fields for every offer:
| Technical field | What the quotation must state | Why it matters |
|---|---|---|
| Fibre and grade | Glass wool or rock/mineral wool; product designation | “Resin bonded” covers different materials |
| Size and tolerance | Length, width, thickness in millimetres, and allowable dimensional tolerance | Prevents area and fit discrepancies |
| Density | Nominal density in kg/m³ and density tolerance | Changes stiffness, acoustics, weight and price |
| Performance | Thermal conductivity in W/m·K, operating-temperature range and fire classification | Catalogue values are not interchangeable |
| Surface and edges | Aluminium foil, tissue, black veil, reinforced kraft, wire mesh or unfaced; edge condition | Facing changes vapour control and installation |
| Treatment and installation | Water-repellent treatment, permitted compression and jointing method | Forced compression reduces thickness and performance |
| Evidence | Current report for the offered grade, showing manufacturer, test date, specimen thickness and test standard | A report for another density proves little |
The commercial section must state:
- Number of slabs, usable square metres, slab dimensions and packing quantity
- Unit rate, GST, freight, unloading, cutting, special facing, minimum order and returnable-packaging charges
- Delivery location, lead time, payment terms and replacement procedure for wet, crushed or incorrectly supplied material
Compare the delivered, tax-inclusive cost for the required usable area. An ex-stock rate per slab or cubic metre can hide freight, waste and unusable damage.
Where slabs fit, and how to install them without losing performance
Rigid resin bonded slabs suit flat or slightly irregular surfaces where insulation must retain a fixed thickness: HVAC ducts, plant-room walls and ceilings, equipment enclosures, partition infill and sandwich-panel cores. They are a poor choice for cavities that need stuffing, repeated flexing or an untested fire-rated assembly.
| Application | Why it fits | Main control |
|---|---|---|
| HVAC ducts | Stable thermal and acoustic lining | State permitted compression and joint method |
| Plant rooms | Rigid, clean-faced surface insulation | Protect edges from impact and moisture |
| Sandwich panels | Consistent core thickness | Match the tested facing, adhesive and fixing system |
| Partitions | Accurate infill between framing | Do not treat a product fire result as an assembly rating |
Install without forcing the slab into place. Measure the opening, cut with a sharp serrated knife, and wear eye and respiratory protection; a crushed edge loses thickness and performance.
- Dry-fit each piece, leaving no open gaps. Use the supplier’s specified adhesive, pins or mechanical clips, and do not puncture a vapour-control facing without sealing the penetration.
- Butt joints tightly, stagger them at corners, and seal foil, tissue or kraft facings with compatible tape or mastic. Do not substitute an untested joint detail in a duct or panel system.
- Keep slabs dry, raised from the floor and covered from rain and direct damage. Replace pieces with delamination, wetting or broken edges.
- Inspect thickness, gaps, alignment, fastener spacing, facing continuity and penetrations before closing the work. Record batch numbers and photograph concealed areas.
Resin bonded slabs versus other insulation formats
Choose a rigid resin bonded slab when you need a self-supporting panel that holds its shape between studs, over a ceiling, inside a plant room, or around rectangular ductwork. Choose another format when flexibility, moisture tolerance, minimum thickness, or high-temperature performance matters more.
| Format | Better choice when | Worse choice when |
|---|---|---|
| Rigid resin bonded slab | You need clean joints, predictable thickness, acoustic absorption and easier mechanical fixing | The cavity is irregular, the slab must be bent, or compression would be needed to make it fit |
| Glasswool | You need a light, flexible fill for large cavities and services with awkward spacing | You need a firm exposed face, high resistance to handling damage or tight dimensional control |
| Rockwool | You need higher temperature tolerance, robust handling or strong fire-performance evidence for the specified product | Low weight, thin build-up and easy cutting are the priorities |
| Rigid foam board | You need high thermal resistance per millimetre, moisture resistance or a continuous insulation layer | Acoustic absorption, vapour-open construction or reaction-to-fire performance is critical |
| Lightly resin bonded mattress | You need to wrap equipment, fill uneven spaces or follow curved surfaces without gaps | You need a flat, load-resistant panel that stays dimensionally stable |
Do not treat “fire-resistant” as proof that a product is non-combustible or that a wall assembly is fire-rated. Check the exact product’s reaction-to-fire report and the complete assembly test.
Never force a slab into a cavity. Compression changes its thickness, thermal resistance and acoustic performance; ask for the permitted compression and jointing method.
How to check Delhi suppliers before accepting delivery
Do not pay against a catalogue image or the lowest ex-stock rate. A resin bonded slab supplier in Delhi should prove that the quoted material exists, matches your specification, and can arrive in usable condition.
1. Request a current test report or certificate for the exact grade offered. Check that it names the manufacturer, product designation, test date, specimen thickness and test standard. A report for another density or thickness does not verify your order.
2. Recalculate the delivered, GST-inclusive price for usable square metres. Add freight, unloading, cutting, special facing, minimum-order charges and returnable packaging. Ask whether the quote is per slab, square metre, cubic metre or pack; freight can rise sharply when low-density slabs fill a truck before they add much weight.
3. Put fibre type, density, thickness, thermal conductivity, facing, dimensions, edge condition and tolerances in the purchase order. Also state the replacement process for damaged slabs and who pays freight for rejected material.
4. Demand stock confirmation showing actual length and width, slabs per pack, pack volume, batch or manufacturing date, storage condition and delivery lead time. Inspect labels, seals, corners and moisture damage before signing the delivery note.
5. Treat “fire-resistant” as incomplete evidence. Ask whether the result concerns reaction to fire or a tested wall or ceiling assembly, including facings, adhesive, framing and penetrations.
Use this same checklist with Shiv Sales Corporation and with resin bonded slab dealers near Delhi; a familiar name does not replace batch, test and delivery verification.

Frequently asked questions
What is the resin bonded slab price in Delhi?
Common 25–50 mm resin bonded slabs cost roughly ₹150–₹650 per square metre. Dense, thicker, or specially faced products can cost more, so use the range for screening rather than as a firm offer.
What should you request from a resin bonded slab supplier in Delhi?
Request a specification sheet stating thickness, density, dimensions, facing, thermal conductivity, fire performance, moisture resistance, batch number, and applicable test reports before ordering.
Where can resin bonded slabs be used?
They fit building and industrial insulation applications where controlled heat transfer, acoustic performance, or fire resistance is required. Select the grade for the temperature, moisture, loading, and fire conditions at the installation site.
How do resin bonded slabs compare with other insulation formats?
Compare them by thermal conductivity, density, thickness, fire behaviour, moisture resistance, compressive strength, joint treatment, installation time, and total installed cost rather than price per square metre alone.
