Usage/purpose
ME501 provides a high performance seal to the perimeter joint between the window/curtain wall and the construction reveal. Due to the intelligent, variable vapour permeability (sd value), when used in an internal UK (warm) environment, it will be vapour-tight, and when used in an external UK (cold) environment it will be vapour open. This means that the membrane is suitable for interior and exterior use providing an air-tight and weather-tight seal whilst always complying with inside tighter than outside principles.
- Complies with principle of ‘inside tighter than outside’ in order to facilitate efficient vapour control
- BBA accredited alternative to EPDM in many applications
- Excellent drying potential (due to the membrane’s vapour permeability) avoiding mould growth and physical damage
- UV stable - will tolerate up to 12 months direct exposure prior to covering
- Fully compatible with illbruck Building Protection Membranes
- Weathertight against driving rain to 1200 Pa
- ME501VV self adhesive version also available
