Keyfix Non-combustible Stainless Steel Weeps can be specified for use in 102.5 mm and 215 mm wide masonry skins.
Description
Keyfix Non-combustible Weep Vents (NCW) are manufactured from Grade 304 stainless steel with an A1 non-combustible fire rating. Its design complements the Keyfix non-combustible cavity tray systems for perp joint adjustability, but can equally be installed over any stainless steel component, such as lintels or masonry.
Unlike weeps manufactured from other metals, the Keyfix NCW will not suffer from electrolytic corrosion associated with the use of dissimilar metals in a wet environment in conjunction with stainless steel. Zinc plated weeps must be placed on top of mortar bed to avoid bi-metallic / electrolytic corrosion between dissimilar materials.
Features and benefits:
- Classified A1 fire rated.
- High performance stainless steel.
- On site simplicity.
- Can be specified for use in 102.5 mm and 215 mm wide masonry skins.
