Cavity ties of 50mm are available in medium duty satisfy AS/NZ 2699-2000. Their rounded ends prevent injury and central hole to assist bond in mortar. 100mm cavity ties in heavy duty cater for larger cavities. These ties satisfy the AS/NZ 2699-2000.
50mm acoustic cavity ties, available from NovaPlas , are the standard medium duty Ni-Ties with each end over moulded with a resilient material. The resilience reduces air and structure borne noises while also reducing impact or vibration in masonry walls. 50mm acoustic cavity ties have the following benefits:
- Ni-Ties will not corrode in areas near the sea or industrial zones because they are chemically resistant and are an alternative to galvanised ties.
- Ni-Ties have rounded edges and are light in weight. This makes handling safe and quick.
- With Ni-Ties chances accidents are low eliminating cuts from sharp edges.
- Ni-Ties comply with existing fire ratings for low and medium density housing.
- Ni-Tie high strength and stiffness make them suitable for areas subject to intense natural conditions such as high wind, earthquakes and cyclones.
- Ni-Ties eliminate the problem of electrolysis in steel frame houses when using dissimilar metals.
- Ni-Ties have acoustic properties higher than metal ties and the Ni Tie acoustic cavity provides further reduction of noise and vibration transference.
- All Ni-Ties are packaged in UV stabilised bags.
50mm face fixed stubbie ties available in medium duty satisfy AS/NZ 2699-2000. These ties are suitable for plywood braced and insulated walls. Every tie is chemically inert.
When fixing Ni-Ties to timber 1 x 10-12 x 45mm (type 17) should be used. When fixing Ni-Ties to steel 1 x 10-16 x 25mm (Tec) should be used.
50mm side fixed veneer ties in medium duty satisfy AS/NZ 2699-2000. Two fixings should be used to prevent rotation while in service.
Ni-Ties are colour coded to assist in identifying classification in the wall and are suitable for steel and timber stud, brick veneer homes or buildings.
When fixing to timber 2 x 10-12 x 45mm (type 17) should be used. When fixing to steel 2 x 10-16 x 25mm (Tec) should be used.
