Application

For sealing interfaces to provide airtight or weather tight seals.


For interior and exterior applications ME220 EPDM is typically bonded to the glazed frame and backing substrate with illbruck OT015 EPDM Paste Adhesive. For interior applications, the ME220 VV self-adhesive variant is preferred.


OT015 EPDM Paste adhesive and Acrylic self-adhesive may require the application of primer and or the creation of an isolation layer before bridging across overspilled or smeared silicone sealants. When using a paste adhesive do not no exceed the proportions specified by illbruck. Consolidate all bonds regardless of variant in use by applying firm pressure and roiling over the top of the membrane with a seam roller. Do not apply in temperatures below 5°C and rising. 


 The self-adhesive version appended 'VV' may not suit some PVCu profiles when used as an external perimeter sealing membrane. Do not use the 'VV' version in areas prone to standing water or areas where prolonged wetting occurs without sufficient drying periods. Use the plain version bonded with OT015 where such conditions exist.

Description

An EPDM-based membrane used for sealing interfaces to provide airtight or weather tight seals. Used for weather sealing the exterior side of the connecting joint between a window or facade construction and an adjacent structure (e.g. wall, concrete panel, steel frame, etc.) or to provide an internal airtight barrier in a similar detail.


Features and benefits:

  • High resistance to mechanical damage.
  • Excellent movement capability in both transverse and longitudinal direction with excellent material recovery after elongation.
  • Excellent weathering, ageing and UV radiation resistance.
  • Excellent moisture vapour barrier.

Manufacturer guidance

In strict accordance with manufacturers' method statement. Application always starts at the cill or threshold. Do not over apply the specified paste adhesive. Window, door and curtain wall applications-Minimum bond to glazing frame is 20 mm. Minimum lap and bond to backing wall/substrate is 50 mm. When applied as linear construction joint seal the membrane should be applied equal distant over the joint with a 50/50 lap to the corresponding substrates and a minimum bond of 35 mm, 50 mm preferred.
