illbruck ME220 EPDM Membrane

• Suitable For: ME220 is an EPDM-based membrane used for sealing interfaces to provide airtight or weather tight seals
• Area of use: Airtight & Watertight: Class 4 (EN 12207) and Class 9A (EN 12208) performance. UV & Weather Resistant: Durable in harsh conditions, from -40°C to +130°C. Flexible & Strong: >300% elongation and >6.5 N/mm² tensile strength. Moisture Barrier: sd-value of 24 m for superior vapour control. Versatile Fixing: Supports adhesives, self-adhesive strips, or gasketed options. Fire Rated: Class E (EN 13501-1) | B2 (DIN 4102-1) compliant.
• Application Method: Substrate Preparation: Surfaces must be clean, dry, and free from dust or grease. Use primer on porous materials as needed. Adhesive Options: CT113 for porous and vertical surfaces OT015 for non-porous substrates – ideal for quick and clean gun application Use a seam roller to fully consolidate adhesive bonds. Overlap Requirements: 100 mm minimum on porous materials 20–30 mm on non-porous materials Gasketed Versions: Four gasket types (K01–K04) are available to suit different frame grooves. Self-Adhesive Option: Acrylic strip bonds to frames; butyl strip bonds to substrates. May require clamping strip for added security. Corners & Head Details: Use ME241 EPDM Corners for robust seals. Include a 100 mm membrane overlap and safety trim at window heads. Sealant Finishing: For exposed edges and overlaps, use OT015 adhesive at a 45° angle for water protection. Always install the membrane tension-free and consolidate all bond lines for long-term airtight and watertight performance.

ME220 EPDM membrane is used for
sealing the connecting joint between
a window or a façade and an adjacent
structure (e.g. a wall, concrete panel,
steel frame, etc.), or to provide an
internal air-tight barrier in a similar
detail. Where the membrane is
positioned in the cold zone however, a
vapour tight membrane such as EPDM
can increase the risk of condensation,
and a vapour open membrane such as
ME501 Duo Membrane HD is normally a
better solution.
If an internal and external membrane
is required, in order to meet the
principle of ‘inside tighter than outside’,
ME220 should be located as the inner
membrane and ME501 Duo Window
Membrane HD as the outer membrane.
This will ensure that the inner seal is
more vapour tight than the outer which
will facilitate drying out of any entrapped
moisture between the two layers.

Application Overview – ME220 EPDM Membrane

The ME220 EPDM Membrane should be installed with consideration of both internal and external joint details. Always size the membrane appropriately and allow for structural movement and loading.

• Substrate Preparation: Surfaces must be clean, dry, and free from dust or grease. Use primer on porous materials as needed.

• Adhesive Options:

  • CT113 for porous and vertical surfaces

  • OT015 for non-porous substrates – ideal for quick and clean gun application

  • Use a seam roller to fully consolidate adhesive bonds.

• Overlap Requirements:

  • 100 mm minimum on porous materials

  • 20–30 mm on non-porous materials

• Gasketed Versions: Four gasket types (K01–K04) are available to suit different frame grooves.

• Self-Adhesive Option: Acrylic strip bonds to frames; butyl strip bonds to substrates. May require clamping strip for added security.

• Corners & Head Details: Use ME241 EPDM Corners for robust seals. Include a 100 mm membrane overlap and safety trim at window heads.

• Sealant Finishing: For exposed edges and overlaps, use OT015 adhesive at a 45° angle for water protection.

Always install the membrane tension-free and consolidate all bond lines for long-term airtight and watertight performance.
