What is the difference between NRC and CAC?
A product’s Ceiling Attenuation Class (CAC) indicates the ceiling’s ability to prevent airborne sound from traveling between adjacent rooms when the dividing wall does not connect with the structural ceiling. A CAC will range between 0 to 45 for ceiling panels. Ceiling panels that have high CAC ratings (30 or greater) and are good at blocking sound from ceiling equipment may not necessarily have a high NRC performance and may not necessarily maintain quality sound absorption.
What does a STC rating measure?
Why is the AC important?
How does the NIC rating differ from other acoustic measurements?
How does stone wool react to fire?
What is measured when testing to the EN 13501-1 standard?
- a material’s ignitability,
- the rate of heat release,
- the rate of spread of flame,
- the rate of smoke emission,
- the toxic gas emission,
- the presence of flaming droplets/particles and/or a combination of these safety
The highest classification a product can achieve under EN 13501-1 is A1. Products with an A1 classification do not contribute to the development and spread of fire. They generate neither smoke nor flaming droplets. Most Rockfon ceilings have an A1 rating.
Why is a product’s fire resistance response important?
Three criteria are measured:
R: Load bearing capacity
The inherent properties of stone wool ensure that fire-resistant Rockfon ceiling tiles provide excellent protection in the event of a fire.
Do ceiling systems in Australia need to be assessed for seismic design?
The three main standards pertaining to suspended ceilings in Australia are:
- AS1170.4:2007 - Structural Design Actions – Earthquake Actions in Australia
- AS/NZS 1170.0.2002 – Structural Design Actions – General Principals
- AS/NZS 2785:2000 – Suspended Ceilings, Design and Installation
How do Rockfon products contribute to indoor air quality?
Can Rockfon ceiling tiles aid the building certification process?
Can you clean a Rockfon ceiling tile?
The Rockfon MediCare range of healthcare ceiling tile products have a durable, highly water-repellent surface that resists diluted solutions of ammonia, chlorine, quaternary ammonium and hydrogen peroxide. They can also be disinfected periodically following a steam cleaning protocol defined by experts and using an adapted surface mop.
Does stone wool provide sustenance for micro-organisms?
- Escherichia coli
- Staphylococcus aureus
- Methicillinresistent staphylococcus aureus (MRSA)
- Stachybotrys chartarum
- Penicillium brevicumpactum
- Alternaria tenuissima
- Aspergillus Brasiliensis
- Sporobolomyces roseum
- Rhodotorula rubra
The Rockfon MediCare range are designed to meet the requirements of zones with different levels of infection risk in healthcare facilities. The products all meet low particle emission requirements and have a clean room classification of ISO Class 5 or better (ISO 14644-1).
Do Rockfon products absorb water?
This means it does not absorb water and nor hold moisture. This makes our stone wool ceiling panels and tiles humidity-resistant and allows them to remain dimensionally stable even up to 100% relative humidity (RH), and in temperatures from as low as 0°C to as high as 40°C.
Will the tiles sag in humid conditions?
Stone wool ceiling panels can be installed in the early stages of construction, when the windows are not fully sealed, without any risk of sagging. The moisture resistant characteristics of stone wool acoustic ceiling tiles means they will remain unaltered throughout the building’s lifecycle, maintaining their shape and physical characteristics.
Rockfon stone wool ceiling panels do not warp, curl or cup. They will not rot, and nor will they corrode. In fact, with virtually no organic content, they are naturally resistant to the issues associated with mould, mildew and microorganisms. Even in consistently ”wet” areas like kitchens, restrooms and leisure centres, the product will not sag.
Can the products be recycled?
One of the most valuable features of stone wool is that it can be made with materials that would otherwise be landfilled or downcycled. Overall, around one-third of our raw materials consist of repurposed waste from metals manufacturing, power plants and wastewater treatment. We can upcycle slag from the metal industry and sludge from water treatment plants for example, and even in small amounts old ceramics like broken bathroom sinks and toilets.
What does “design for disassembly” mean?
Using building materials that are modular and easy to dismantle also make it possible to reuse them when making changes to spaces, rather than having to dispose of them.
What is an EDP?
How does an EDP aid in the building certification and verification process?
The impact on the environment is considered by calculating the effect of a product from ‘cradle-to-gate’. In other words, it must account for upstream environmental impact (the raw material resourcing/extraction and their transportation to the manufacturing facility) and the impact of the production itself.
In order to communicate the environmental profile of Rockfon products, the company has taken steps to simplified their EPDs. You will now be able to find two EPDs; one for its high- density products and a second for its low-density products.
By using Rockfon specific EPDs, which are independently verified, a customer can achieve maximum credits in their LEED®, BREEAM® or DGNB® building certification efforts. The transparency and consistency of the Rockfon EPDs, according to the EN15804 standard, allows the customers to use the results and calculate the building’s life cycle assessment (LCA) that is required to gain elite-level certifications.
