Can I paint my grilles and registers?
It is preferable to leave Paltech grilles, registers and diffusers unpainted. Painting plastic can increase the dust and grime accumulation on the product, and make the product more difficult to clean. The unpainted finish will age much better than paint, and retain a high quality finish for many years.
If the product is to be painted, follow these basic rules:
- Always remove the product to paint – do not paint in situ
- Prime the surface with a good quality primer
- Use a good-quality household acrylic paint
- A sprayed finish gives the best results, but brushing will suffice
What are the fire requirements for supply grilles?
Fire hazard resistance of supply air outlets
BCA (2009), Part C1 , FIRE RESISTANCE AND STABILITY – Deemed to satisfy provisions states:
C1.10 (a) The fire hazard properties of any material ar assembly in a Class 2 to 9 building must comply with
- (i) for floor materials, wall coverings and ceiling lining materials, Specification C1.10a and
- (ii) for other materials, Specification C1.10…
(c) The requirements of (a) do not apply to a material of assembly if it is –
- (x) a face plate or neck adaptor of supply and return air outlets of an air handling system
When quoting or supplying air outlets, contractors also need to consider whether a specifier, builder or consultant has included other fire resistance provisions. These may be additional requirements to the NCC/BCA deemed-to-satisfy provisions. There may also be state or local regulations that vary the NCC/BCA deemed-to-satisfy provisions.
Paltech cone diffusers, Downjets, and MDO’s are made from ABS (Acrylonitrile butadiene styrene) polymers. In a review of the literature, Rutowksi and Levin (1986) conclude that:
(1) Many combustion products are generated during the decomposition of ABS.
(2) The principal gases which appear to be responsible for the observed toxicity are HCN and CO.
(3) The thermal degradation products of ABS plastics demonstrate a measurable degree of toxicity. However, the toxicity of ABS combustion products is comparable with the toxicity of the degradation products of other common polymetric materials.
