Cleverseal Flame Retardant Seals
Did you know that Cleverseal Cinderseal Flame Retardant seals, are the market leader and has been specifically developed for protection against ember attack for most Australian garage doors types? Cleverseal Cinderseal is PA6 Nylon flame retardant material which self-extinguishes when ember contact is made. It achieves a flammability index of less than 5. It is deemed to comply with AS3959:2018 Construction of buildings in bushfire-prone areas.
What is BAL?
BAL is a term used to quantify the bush fire risk of a development. BAL stands for 'Bush fire Attack Level' and it is affected by your location, surrounding vegetation and he space between your development and this vegetation.

Cinderseal - Flame Retardant Sealing System (Bushfire)
The below table shows which Cleverseal Cinderseal project will suit in meeting selection for requirements of the latest Australian Bushfire Standard AS3959:2018.
Cleverseal Sealing Systems can be used on a range of door types both new and retrofit.
|BUSHFIRE EMBER PROTECTION||BAL 12.5||BAL 19||BAL 29||BAL 40||BAL FZ|
|Cinderseal Flame Retardant Nylon PA6 Bristle Brush BPL (Brush Pile Length)||1250||1500||2250||2500||2750||3000|
2500 / 2750 / 3000 are made up of 1250/1500 length combinations.
Nylon 66 Polypropylene are NOT flame retardant.
It also contains UV stabilisers. UV stabilisers? What are they?
Well here’s your science lesson for the day!
UV stabilisers in polymer, a component of our flame retardant brush, are used directly on the brush to prevent the various effects of photo-oxidation (the degradation of polymer caused by light).
Untreated Polymers get weathered due to the impact of heat and ultraviolet light. The UV stabilisers dissipate the absorbed light energy from UV rays. This reduces the absorption of UV rays by the polymer which reduces the rate of weathering.
Crikey! Can you run that past me again?! OK, here goes…
Basically, our Cleverseal Cinderseal flame retardant bristle brush seals, contain UV stabilisers, which prevent the brush from weathering, by deflecting heat and light. Our bristle brush filament self-extinguishes when ember contact is made. Cleverseal Cinderseal can reduce airflow into your garage by 96% if all 4 sides are sealed correctly.
Meaning, that your purchase will stand the test of time from the elements and provide a first line in protection for you or your customers garage door.
It's like Batman's budgie smugglers never fading while sunbathing at Bondi Beach in the heat of summer.
