When it comes to ensuring the durability, weather resistance, and airtight sealing of doors and windows, an EPDM seal is often a firm favourite. The versatile EPDM material delivers exceptional performance across a range of sealing applications, making it popular among door manufacturers, joiners, and facilities managers alike. In this blog, we explore the benefits of EPDM rubber seals, their different types, and why they should be your first choice for sealing needs.
What is an EPDM Seal?
EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber known for its outstanding resistance to heat, weathering, ozone, and aging. An EPDM seal is a flexible strip or gasket made from this material, used primarily to create airtight and watertight seals in doors, windows, and other building components, as well as in the manufacturing of a variety of internal and external units.
What are the Advantages of EPDM Seals?
EPDM seals provide many benefits over silicone or neoprene. EPDM sealing strips are often the preferred choice because they provide:
Superior Weather Resistance
EPDM seals withstand extreme temperatures, UV rays, and ozone exposure without degrading
Durability
These rubber seals reduce the need for frequent replacement, as they’re able to maintain their strength and elasticity over time
Excellent Air & Water Sealing
The rubber’s flexibility ensures tight seals that prevent drafts, water ingress, and noise pollution
Chemical Resistance
EPDM is ideal for industrial and commercial environments
Affordability
Despite its exceptional performance, EPDM rubber seals are affordable and easy to work with
Different EPDM Seal Profiles for Different Applications
We stock EPDM Sealing Strips in five popular profiles, commonly used to seal gaps around doors and windows and provide an effective barrier against air and moisture. They also help improve energy efficiency by maintaining indoor temperature control and creating an airtight and waterproof seal. Draught-excluding EPDM seals are also used to protect and seal panel or glass edges, preventing damage and improving overall structural integrity.
What are the Benefits of Using EPDM Seal?
Whether used in door manufacturing or retrofit, the choice of sealing material can significantly impact product quality and building performance. Here are the key benefits of EPDM seal:
Energy Efficiency: By minimizing air leaks, EPDM rubber seals help reduce heating and cooling costs.
Noise Reduction: EPDM’s sound-dampening properties create quieter indoor environments.
Enhanced Weather Protection: These seals prevent water ingress that can cause rot and corrosion in door frames.
Easy Installation and Maintenance: EPDM seals are flexible and can be cut or shaped on-site, simplifying installation and replacement.
What are the Key Considerations When Selecting EPDM Seals?
Before choosing an EPDM seal for your project, keep these factors in mind:
- · Ensure you choose a seal profile and size that match the gap or edge to be sealed
- · Consider exposure to UV, ozone, chemicals, and temperature extremes
- · Some EPDM seals come with adhesive backing for easy installation
- · Check compatibility with door materials and finishes
Why Choose EPDM Rubber Seal?
Offering a powerful combination of durability, flexibility, and resistance to harsh environmental conditions, EPDM rubber seals are a strong choice. Whatever the application, EPDM sealing strips provide a dependable solution.
