Rubber That Seals a Building Against Water, Wind and Movement.
Extruded EPDM glazing and weatherseal profiles, cellular expansion joint seals, building-services gaskets and vibration mounts for plant — extruded and moulded to your drawing in Nashik. The moulded line is ISO 9001:2015 certified. Compounded in-house, so the ozone and UV resistance a facade needs for twenty years is formulated rather than bought in.

Seven Product Lines on One Project
Extrusion Profiles
Glazing gaskets, wedge and H-sections, door and window weatherseals, cabinet and shutter seals. Die cut in-house, so a non-standard section is a drawing rather than a compromise.
Sponge & Foam Rubber
Facade and curtain-wall expansion joints, closed-cell backing, self-adhesive foam tape, acoustic isolation pads.
Gaskets
Flange and body gaskets for building-services pipework, pumps, tanks and plant.
Anti-Vibration Mounts
Isolation for chillers, air-handling units, generator sets and pumps — the plant that transmits structure-borne noise into a building.
O-Rings
Building-services pipework, valves, pumps and fire-main couplings.
Rubber Lining & Skirting
Tank, sump and pipework lining for water and effluent plant on infrastructure projects.
Bonded Components
Bonded acoustic and vibration pads where the rubber is vulcanised to a steel plate rather than glued to it.

Extruded weatherseal profiles, bubble and fin sections, glazing beads and cabinet seals.
CompoundEPDM · CR
Roof and waterproofing
Self-adhesive closed-cell tape, upstand and penetration seals, membrane termination tape.

On a Facade, Ozone Decides Before Temperature Does
External seals fail by ozone cracking and UV embrittlement, not by reaching a temperature limit. A twenty-year facade seal spends its life between −5 and +65 °C and still perishes, because sunlight and atmospheric ozone attack the polymer backbone. Every compound we mix is available; these are ranked for building duty.
| If the duty is | Compound | Service temperature | Note |
|---|---|---|---|
| External — facade, glazing, roof, weatherseal | EPDM | −40 to +140 °C | The default for anything exposed. Outstanding ozone, UV and water resistance; tested to ISO 1431-1. Never where oil or fuel is present |
| Structural movement, acoustic and vibration pads | Natural rubber | −20 to +90 °C | Best damping and flex-fatigue of the eight, which is what a load-bearing pad needs. Protected positions only — poor ozone resistance |
| Marine and coastal exposure, moderate oil, flame-retardant grades | Neoprene | −40 to +120 °C | The compromise where salt air, some oil and a flame-retardant grade are all wanted at once |
| Plant-room pipework carrying oil, fuel or hydraulic fluid | NBR | −30 to +120 °C | Generator fuel lines and hydraulic plant. Never on a facade — nitrile has poor ozone resistance and will craze in sunlight |
| High-temperature services, flue and boiler-room gasketing | Silicone | −60 to +220 °C | Where temperature genuinely governs. Low tear strength, so not for a section that is stretched over a frame |
| Abrasive water, low-cost protected duty | SBR | −30 to +100 °C | Internal and protected positions only. No exposure, no oil |
| Aggressive chemistry in effluent or process plant | FKM | −20 to +250 °C continuous to +200 °C | Rarely justified on a building. Specify on the medium, not the temperature |
| Hot oil and oil mist | AEM | −40 to +175 °C continuous to +160 °C | Rarely a construction duty. Listed because every compound is available |

Four Things We Will Not Quote
Rubber appears in parts of a building where the product is not really rubber, it is a certified assembly. We would rather tell you now than at qualification.
| Not supplied | Why | What we can do |
|---|---|---|
| Laminated elastomeric bridge bearings | A structural product type-tested and load-certified to IRC:83 Section IX, IS 15462 or EN 1337-3. We hold no structural product approval and a bearing sits under a deck. | Plain rubber bearing pads and acoustic isolation pads for non-structural duty, quoted against your load and area |
| Fire-rated and intumescent seals | A fire rating is certified against a specific tested assembly by a third-party laboratory to IS 3809, BS 476 or EN 1366. A flame-retardant compound is not a fire rating and we will not let the two be confused. | Flame-retardant neoprene grades where the specification asks for a compound property rather than a tested assembly. Third-party testing arranged on request |
| EPDM roofing membrane systems | Single-ply roofing is a warranted system with installer certification behind it. The warranty is the product. | Closed-cell EPDM tape, upstand and penetration seals, and termination detailing that goes with someone else’s membrane |
| PVC waterstops | PVC is not a vulcanised rubber and we do not extrude it — the same reason we decline polyurethane liners and polyurethane hydraulic seals. | Rubber waterstops and construction-joint seals in EPDM or natural rubber, where the specification permits them |

FREQUENTLY ASKED QUESTIONS
Technical & commercial questions
Which rubber lasts longest on an external facade?
EPDM, and it is not close. External seals fail by ozone cracking and UV embrittlement rather than by reaching a temperature limit, and EPDM resists both better than anything else we mix. Nitrile is the common cheap substitute and it crazes within a season in direct sun. We test ozone resistance to ISO 1431-1 at our NABL partner laboratory and will report it on the compound supplied.
Do you supply elastomeric bearings for bridges?
No. Laminated elastomeric bridge bearings are a structural product, type-tested and load-certified to IRC:83 Section IX, IS 15462 or EN 1337-3, and we hold no structural product approval. We do supply plain rubber bearing pads and acoustic isolation pads for non-structural duty, quoted against your load and area — but if your specification calls up a laminated bearing, we are not your supplier and will say so at enquiry rather than at qualification.
Can you supply sealing rings for concrete pipes and manholes?
Yes. Sealing rings to IS 5382 for water mains, gas mains and sewers, and to EN 681-1 for water supply and drainage pipe joints. Send the pipe standard, the joint type and the ring section — those are on our water and fluid management page, and the same team quotes both.
Are your seals fire rated?
No, and the distinction matters. A fire rating is certified against a specific tested assembly by a third-party laboratory to IS 3809, BS 476 or EN 1366 — it belongs to the assembly, not to the rubber. We supply flame-retardant neoprene grades where a specification asks for a compound property, and we will arrange third-party testing on request. We will not describe a flame-retardant compound as a fire-rated seal.
What is the minimum order for extruded profile on a project?
We deal in bulk, and on extruded profile the minimum is quoted per profile against total length rather than as a piece count — a curtain-wall package and a window run are not comparable quantities. Moulded components carry the standard minimum of 10,000 pieces per part number, per compound. Send the section and the metreage with the drawing and we will quote it.
Can you make a non-standard profile for a facade system?
Yes — that is most of what we do on this sector. Dies are cut in-house, so a section drawn for your system is a drawing rather than a compromise, and corner mouldings can be vulcanised to the profile so the joint is not a butt splice on site. Send the section drawing and the annual metreage and we will quote the die with it.
Request a Construction Quotation
Send the section drawing and the annual metreage, or the moulded part drawing and the quantity. Tell us whether the position is external or protected — that single answer decides the compound before anything else does. Our engineering team responds within 48 hours with a compound recommendation, dimensional confirmation and a quotation.
