Steel Cementitious Air Tight System

The ASP Air Tight System is a system that is specifically designed to minimise air leakage, when the access floor is to be used as a plenum. This system incorporates the use of a clip on air tight stringer that acts as a barrier in between the panels to eliminate air leakage. This system is recommended for applications such as:

• General Offices
• Banks
• Learning Institutions
• Libaries
• Casinos
• 5 and 6 green star rated buildings and projects

Inbuilt Expansion Joint and Cut Out
The panel has a special expansion cut out, and the pedestal head is fitted with an expansion gasket designed to keep the panels separated by 0.3mm at all times. This eliminates the panels clicking or rubbing up against each other during expansion.

4 Corner Screw Panel

Screw hole in each corner to allow panels to be individually screw fixed providing greater rigidity as well as easier and faster access.

AT Cavity Insert/ AT Stringer
Clip insert for the attachment of the AT stringer to system.

Finishing Panels
Full bearing 600 x 300mm and 600 x 800mm panels designed to minimize small off cuts around columns and finishing off to the perimeter. The 600 x 300 panel may also be used when there is a necessity for a 300mm x 600mm air grille.

The ASP Ultrafix AT air highway is a ready made clipped on system that can be incorporated into any application requiring an under floor air highway or plenum detail.

The specialised sponge rubber creates an air tight seal to ensure that the zones are completely sealed. 

1. Inbuilt Expansion joint gasket
This patented inbuilt expansion joint gasket detail ensures that the panels are held 0.3mm apart

2. Pedestal head
Pedestal head is made of die formed aluminium to form a solid support to mount the access floor panel to

3. Clip on AT stringer cavity
Cavity for AT stringer attachment

4. AT stringer
0.8mm thick aluminium clip on stringer with 3mm sponge rubber

5. Screw Fix Locator
The panel is screw fixed through this locator on every corner

6. Steel thread rod
18mm x 150mm steel thread rod that gives a range of adjustment from 50mm +/- from the FFH

7. Sound Impact Buffer
A sound and imapct rubber washer encased in a steel housing pocket intended to eliminate metal on metal sound transfer to the slab

8. Adjusting and locking nut
Adjustment: Nut can adjust to the required length of the steel thread rod
Locking: Nut has an inbuilt vibration proof locking device, to ensure that once locked the pedestal height is static

9. Pedestal Tube
Provides rigidity and stability to steel thread rod

10. Pedestal Base
100mm x 100mm pedestal base that provides a solid weight bearing platform for the access floor. Pedestal base has 4 fixing holes

1. Air Tight Stringer Support Gasket
Support Gasket allows air tight stringer to continue to perimeters in order to keep air tightness

2. Pedestal Head and Welded Steel Thread Rod
90mm x 90mm steel flat head pedestal designed to provide a solid base for the panel, positioned as perimeter pedestals. A 18mm x 150mm steel thread rod that is welded onto the bottom of the pedestal head with an adjustment range of 50mm +/- from the FFH

3. Locking Nut
Nut has an an inbuilt vibration proof locking device, to ensure that once locked the pedestal height is staic

4. Pedestal Tube
Pedestal tubes provides rigidity and stability to steel thread rod

5. Pedestal Base
100mm x 100mm pedestal base that provides a solid weight bearing platfrom for the access floor. Pedestal base has 4 fixing holes

AT Stringer
AT Stringer clips into the AT cavity of the field pedestal to minimize the air leakage lost in between the panels. This standard AT stringer is used throughout the entire system. The top of the stringer comprises of 3mm thick sponge rubber to act as a barrier in between the panels to decrease the air leakage.
