Buying Guide: Key Considerations For Epdm Rubber Extrusions And Seals

EPDM rubber extrusions and seals vary by geometry, tape adhesion, and environmental tolerance. Buyers should evaluate the following considerations to choose the best option for their project.

  • Material composition and density: EPDM seals offer excellent weather resistance and ozone protection. Higher foam density can provide better sealing against air gaps but may be stiffer, influencing installation in curved or tight corners.
  • Profile and size: Bulb, D-shaped, and ribbed profiles serve different sealing gaps. Ensure the profile matches the target edge or joint dimensions for an effective seal without excessive compression.
  • Adhesive backing vs. mechanical fastening: Tape-backed seals (3M 4011, 9485EK) simplify installation but might require surface preparation for optimal adhesion. Consider surface type and climate when selecting adhesive-backed options.
  • Temperature and weather tolerance: Exposure to heat, cold, sunlight, and moisture affects long-term performance. For outdoor or automotive use, prioritize UV and ozone resistance and low-temperature flexibility.
  • Application suitability: Marine, automotive, and RV contexts have specific requirements for water sealing, noise attenuation, and vibration control. Check manufacturer recommended applications to ensure compatibility.
  • Installation effort and maintenance: Some products are designed for quick installs, while others require cutting and precise fitting. Also consider replacement intervals and ease of removal if the seal needs upgrading.
  • Made in USA or regional supply: Local manufacturing can influence lead times and availability, which matters for projects with tight schedules.

Comparisons

For projects prioritizing ease of installation and quick sealing, tape-backed EPDM options (such as those from ESI and Tintvent) provide straightforward methods. If you need a longer continuous seal for expansive roof or marine runs, thicker EPDM sheets like RubberGard roofing material offer robust waterproofing, though installation may be more involved and require specialized tools. For gap-filled doors and windows, D-shaped and ribbed profiles from multiple brands deliver versatile options that balance compression and resilience. Always verify compatibility with your substrate, the intended climate, and the required service life when selecting between profiles and backing materials.

Consider obtaining samples or testing cut-to-length pieces when possible. This helps confirm fit, adhesion, and seal integrity before committing to larger purchases. In residential or light commercial settings, a combination approach—using tape-backed seals for quick returns and thicker sheets for roofing or marine contexts—can maximize performance while controlling costs.

Setting Blocks | The importance of using setting blocks & correct placement

What is a setting block?

  • Blocks made of neoprene, EPDM, silicone, polypropylene or other elastomeric material, used to support the bottom edge of a pane of glass when glazing it into a frame.

Principle functions of settings blocks:

  • Provide a cushion to support a glass pane’s dead load
  • Provide the proper glass bite at the cill
  • Prevent glass edges from touching the frame thereby preventing damage to the glass
  • Prevent glass edges from being immersed in water and facilitate drainage and drying

Important notes when installing setting blocks:

  • Glass-to-metal contact must be avoided at all times by using setting and location blocks having a hardness of 50⁰ to 90⁰ shore A durometer.
  • Only use blocks made of neoprene, EPDM, silicone, polypropylene or other elastomeric material.
  • Setting blocks should have a minimum thickness of 3mm and be at least 27mm in length per square metre of
    glass area.
  • When glazing laminated glass and/or sealed insulated glass units, drainage should be provided to prevent the glass edge being submerged.
  • Two or more 7mm diameter holes or 5mm x 9mm slotted holes, or larger, should be equally spaced in the c i l l s e c tion of s a sh or fr ame to a l low for ventilation/drainage of the cill section.

SETTING BLOCKS

There are four principal functions of setting blocks which are essential to understand if their installation is to be successful:

  • Provide a cushion for the glass panel to sit on and support the panels dead load

  • Enable the proper glass bite at the cill.

  • Glass edges are prevented from touching the cill frame because the setting block ensures there is the correct glass-to-metal clearance

  • Where applicable setting blocks can be used to retain drainage/weep baffles

In terms of design requirements and with a recommended hardness of 85(+/- 5) Shore A, thermoplastic, silicone, EPDM or neoprene are all suitable, although only EPDM or dense silicone should be used in structural glazing systems. Chemical compatibility with the various sealants used in structural glazing systems is of paramount importance and the setting blocks must be submitted to the sealant manufacturer for compatibility testing (according to ASTM C-1087 or similar) prior to system installation.

Setting blocks should not interfere with the installation of glazing gaskets and should allow any water in the cill to flow past freely. When setting blocks exceeding 19 mm are specified, the glass supplier should approve sizing. It is essential that any setting block is so designed that there is no shifting outward and inward in the cill gutter, otherwise there will not be constant glass support. Removable blocks should be wider – 1.50 mm each side – than the glass unit. If the glass unit were to shift outward or inward in the cill gutter the block contacts the glazing leg or stop before the glass.

Dimensions are relatively simple to adhere to. A setting block should not be less than 100 mm long. When the glass is more than 3.7 sq m, the setting block length should be increased by 25 mm for every square metre of glass area.

When it comes to the preferred location of the setting blocks, there are a number of points to bear in mind. The normal preference is for the two setting blocks to be at the quarter points, but there can be exceptions to this. Most commonly, if it is felt that the quarter-point location will lead to excessive deflection of the horizontal cill, the setting blocks can be moved equally towards the glass panel corners. The one important qualification is that under no circumstances should the outer end of the setting block be closer than 150 mm to the corner of the glass.

Once installed, the full thickness of the IG (insulated glass) unit should be resting on the setting block when the exterior glazing medium is compressed. To ensure this, the block should be a minimum of 28 mm wide for a 25 mm unit. The setting block should also have a minimum 6 mm from the bottom of the glass edge to the metal cill.

In structural glazing applications where the glass-to-glass joint is to be sealed flush with a silicone sealant, the setting block can be set back from the outer glass edge slightly to allow weather seal sealant cover. The rule is that the setting block must extend to a minimum of 50 per cent of the thickness of the outer pane of glass to offer adequate dead load support.

Finally when it comes to installation, the top surface of the setting block should he on a level plane. This provides proper support to the glass. It may be necessary for the bottom of the block to be sloped, to accommodate the outward slope of the cill’s web and to enable correct drainage.

EPDM Dual Durometer Seals

Dual durometer seals rubber products are extrusions with different areas of hardness. Typically, the harder rubber is used for attachment while the softer rubber is used for sealing.  Sometimes, different materials are used because of design considerations such product color schemes or the use of pressure-sensitive adhesives (PSAs).

epdm dual durometer seals

By fabricating dual durometer rubber into a single part, a product such as window seal can have areas with different physical properties to meet application requirements. With window channels, the harder window rubber attaches to the window frame and the softer window rubber faces the glass window. Durometer is not limited to window seals, however, and is used with both sponge and solid profiles.

Hebei Shida Seal Group is a IATF 16949 certified manufacturer, supplier, and exporter of custom dual durometer seals, EPDM seals and gaskets, dual durometer rubber extrusions for automotive, heavy truck, among other industries from Hebei, China.
