Since its inception our premium NS440 slat has consistently proven to be a high quality, robust and well accepted profile so therein provided the perfect solid platform on which to develop the “HDF” profile.
The development and introduction of the High Density Foam (HDF) offers remarkable advantages such as increased strength and security for a variety of application where there is a high wind or high risk. The HDF is injected into the slat profile during the manufacturing and roll- forming process under controlled conditions
HDF WIND LOCK SHUTTER SERIES
The HDF Wind Lock Shutter Series incorporated the HDF slat profile, restrained slat inserts and the heavy duty guides.
The increased density in the HDF profile allows the slat inserts to be firmly screwed into the foam with two 25mm long screws rather than being stapled or punched as per the procedure of normal residential slats
The restrained slat inserts are deigned to lock with a central channel that would require considerable force to disengage. The restrained Guide has been specifically designed to cope with the added forces that the HDF slat will place on it. The wall thickness and overall engagement has been increased to allow for the restraining insert
CYCLONE TESTING AND RATING
The HDF Wind Lock Shutter underwent cyclone tests at the Cyclone Testing Station, James Cook University, Queensland and was approved for a Category 3 Cyclone Rating
The test involves fitting the HDF Wind Lock Shutter to an air box facility which then stimulates the enormous wind loads that can be encountered under tropical cyclone conditions
There are two appropriate Australian Standards that have been satisfied
-Australian Standard AS/NZS 1170.2—2002 Structural Design Action Part 2. Wind Actions was used to determine the cyclonic wind loading for roller shutters fitted to a suburban house with an average roof height of 5m located in a sheltered Terrain Category 3 Region C cyclonic location. The design wind speed is calculated to be 47 meters per second (169.2 kl/h)
-The Australian Standard AS 4040. 3—1992 Methods of Testing Sheet Roof and Wall Cladding, Method 3 Resistance to wind Pressures for cyclone regions was used to an ultimate load pressure of 2.50kPa, which is needed to fulfil the requirements.
The HDF Wind Lock passed cyclic fatigue loads of 10,200 cycles at incremental increases to the final load supporting the final single cycle pressure of 2.5kpa for 1 minute. The shutter deflection only increase to a nominal distance of Choose from 240v electric— remote or spring loaded, backed up by the Nu Style 10 Year Warranty The HDF Wind Lock Shutters function the same as residential grade shutters and will also

Features and Benefits
Bush Fire Attack Level (BAL) 40
Premium strength and security
Wide span options available
Can be Powder coated 10’s of colours
During a bush fire one of the most common causes to a house fire is burning embers igniting the building itself.
The NSX profile Roller Shutters have been designed to meet a BAL (bush fire attack level) of 40 helping prevent homes from burning to the ground whilst others properties might not be so lucky.
The NSX Shutter has been extensively tested by the CSIRO under server bushfire simulated conditions and proved to be able to withstand a maximum radiant heat exposure of 40kw/m2 after 60 minutes. As no ignition or flaming was observed through the testing the NSX Shutter has received a Bushfire Attack Level (BAL) of 40
