Indoor environment

We are undertaking a LEED environmental assessment and have identified VOC’s as a potential credit for our project. Do Rockfon products meet certain standards?

We can confirm that Rockfon ceilings comply with Class E1 emissions in accordance with BS EN 13964 suspended ceilings in relation to VOC's - as detailed in e.g. BREEAM.

BS EN 717-1:2004 is referenced within BS EN 13964 as the specific test method for VOC emission and to be classified E1, products must demonstrate a steady state concentration level of ≤ 0.1 ppm (0.12mg/m3).

Rockfon ceiling tiles have a very low release of VOC's and many millions of m2 have been successfully used, and continue to be used, in all types of projects globally since 1962.

We can confirm that Rockfon tiles do not contain, nor have they ever contained, asbestos.

How do Rockfon products influence the indoor climate?

Although we cannot control the quality of the outside air or ventilation, we can ensure that our products contribute positively to the indoor climate regardless of where they are installed.

  • All our products fulfill E1 classification, guaranteeing that they exceed European Union requirements for formaldehyde emission.
  • The strict Finnish Indoor Climate label, M1 and the Indoor Climate Label have been attributed to a representative panel of our products, showing that they go beyond legal requirements for emissions in indoor environments.
  • Some of our products are classified ISO Class 5 or less, meeting cleanroom requirements for particle emissions.
  • We do not use photocatalysts, as scientific studies have found they can contribute to secondary emissions that are detrimental to human health. (WHO 1989, Wolkoff et al 1997).

Why is light reflection important for indoor climate?

Poor lighting can result in eye strain, fatigue and aching which in turn is likely to lead to deterioration in performance, particularly if work relies on visual equipment such as computer-based job roles. As this type of work is now common place, the importance of lighting for visual health and performance at work is likely to become increasingly important. Light is important to our wellbeing and performance.

The quality of modern artificial light has improved, but the most comfortable and economical light still comes from the sun, although not sufficient and often combined with artificial light. As a result, not only the amount of light, but also the quality of light is important. Both need to be adapted to the working circumstances in a room. The light reflecting capacity of a ceiling will not only contribute to a reduction in electricity bills but will also improve the quality of lighting conditions. Next to sunlight and artificial light we can make a distinction between direct and indirect light. Direct light will light directly, whereas indirect light is the result of light reflection. As the ceiling is the only surface in a room that is completely visible, the light reflection should be as high as possible to make effective use of the light.

A ceiling with the right combination of high light reflection and a good spread of light (light diffusion) leads to a uniform and accurate spread of light in a room, leading to a reduced need for light fixtures.

Thermal insulation properties of ceiling tiles

Better insulation of buildings is a profitable way to reduce the CO2 emissions; it is a low hanging fruit in combatting climate change. Insulation reduces today’s unnecessary waste of fossil fuels from buildings which are responsible for 40% of the EU and US energy consumption and a major contributor to man-made CO2 emissions. The developing countries - struggling with energy poverty and air pollution – also has a need for buildings that waste less energy and emit less CO2.

Although we are primarily designed for acoustic solutions, there are also situations where the benefit of the intrinsic thermal insulation capacity of ROCKWOOL base material, as a major component of Rockfon ceiling tiles, can be used efficiently.

This is the case when shopping malls build over parking garages as well as in flat-roof buildings or in old buildings with cold cellars. The Rockfon ceiling needs to be seen as part of the total thermal insulation solution taking into account building physics (e.g. condensation, avoiding thermal bridges, etc). We provide products specially designed for thermal insulation in combination with acoustic absorption.

Do your products contribute to BREEAM credits, specifically regarding VOC's in section HEA2.3?
