When it comes to creating reliable and weather-resistant window and door systems, the role of the rubber gasket is often underestimated. This small yet essential component ensures airtight sealing, reduces energy loss, and protects buildings from dust, water, and noise infiltration. At ALTIMA India, we supply high-quality EPDM gaskets, EPDM seals, and rubber door seals that are engineered to perform in India’s varied climates.
In this detailed guide, we’ll explain what rubber gaskets are, the importance of EPDM material, different types of rubber seals, and why ALTIMA India is the trusted partner for fabricators, builders, and contractors across the country.
What is a Rubber Gasket?
A rubber gasket is a flexible sealing element designed to fit between two surfaces, preventing leakage of air, water, or dust. In the fenestration industry, gaskets are used in uPVC and aluminium windows and doors to ensure:
- Airtight closure
- Weatherproof sealing
- Smooth door and window operation
- Longer product life
Made from high-quality materials like EPDM (Ethylene Propylene Diene Monomer), rubber gaskets are known for their resistance to heat, UV rays, and harsh weather conditions.
Why Are Rubber Seals Important for Windows and Doors?
In modern construction, the demand for energy efficiency and comfort is higher than ever. Rubber seals play a major role in this by:
- Blocking Dust and Noise – A proper rubber door seal keeps outside dust and unwanted noise from entering.
- Preventing Water Leakage – EPDM seals ensure water doesn’t seep inside during heavy rains.
- Energy Efficiency – By preventing air leaks, gaskets reduce the need for excess cooling or heating.
- Extended Lifespan of Systems – Rubber gaskets reduce wear and tear on window and door frames.
Without the correct gasket, even the most expensive windows or doors can fail in performance.
Types of Rubber Gaskets for Fenestration
At ALTIMA India, we manufacture and supply different types of rubber seals to meet specific project requirements.
1. EPDM Gasket
The most widely used type in windows and doors. EPDM gaskets are known for:
- High resistance to UV light and ozone
- Durability in extreme temperatures
- Excellent flexibility for a tight seal
2. EPDM Seal
EPDM seals come in different profiles such as D-type, star-type, and push-type, designed for various frame systems. They ensure airtightness while allowing easy installation.
3. Rubber Door Seal
Installed around the edges of doors, these seals stop drafts, water, and noise from passing through. Commonly used in aluminium sliding doors and uPVC casement doors.
4. Window Rubber Seal
Designed specifically for uPVC and aluminium windows, these seals improve insulation, reduce rattling, and provide a secure closure.
Benefits of Using EPDM Rubber Seals
The choice of material defines the performance of a gasket. EPDM gaskets and EPDM seals are the most preferred because:
- Weather Resistance – Performs well in hot summers, monsoon rains, and cold winters.
- Long Life – Unlike PVC or cheaper alternatives, EPDM retains elasticity for years.
- Eco-Friendly – Recyclable material with minimal environmental impact.
- Versatility – Works with uPVC, aluminium, and even wooden window and door systems.
Rubber Gaskets vs Other Sealing Materials
- PVC Seals – Less expensive but degrade quickly in sunlight.
- Silicone Seals – Flexible but not as cost-effective for large-scale use.
- EPDM Seals – Provide the best balance of durability, cost, and performance, making them the industry standard.
This is why ALTIMA India exclusively supplies EPDM rubber gaskets for long-lasting performance.
Applications of Rubber Gaskets in Construction
- uPVC Windows and Doors – To ensure smooth sliding or tight casement locking.
- Aluminium Windows and Doors – To enhance weather resistance and noise reduction.
- Industrial Enclosures – Used in panels and machinery requiring airtight sealing.
- Commercial Buildings – For large-scale projects where energy efficiency is a priority.
- Residential Homes – Everyday use in keeping homes comfortable, quiet, and weatherproof.

Frequently Asked Questions (FAQs) About Rubber Gaskets
1. What is the difference between a rubber gasket and a rubber seal?
A gasket is a general sealing component, while seals (like EPDM seals) are designed for specific applications such as windows and doors.
2. Why are EPDM gaskets preferred in India?
Because EPDM material withstands India’s heat, dust, and humidity far better than PVC or silicone alternatives.
3. How long do rubber door seals last?
High-quality EPDM rubber door seals can last over 10 years with minimal maintenance.
4. Can I replace rubber seals in uPVC windows myself?
Yes, with basic tools. However, for large projects, it is recommended to rely on professional fabricators.
5. Why buy rubber gaskets from ALTIMA India?
ALTIMA India provides precision-tested EPDM gaskets and seals, available in bulk with nationwide supply for fabricators and contractors.
