If you're a ventilation designer or installer, your role extends beyond designing or setting up a duct system. It’s your responsibility to foster a conducive indoor environment that’s comfortable, healthy, and productive. A significant element that often goes unnoticed in this pursuit is sound reduction. An essential product for a quiet ventilation system is the simple sound attenuator.

Creating a healthy indoor environment often brings to mind factors such as temperature, humidity, and air quality. However, one essential yet frequently overlooked element is acoustic. Unwanted or disturbing noise can significantly impact our comfort, well-being, and health, thus making sound reduction a vital part of creating an optimal indoor environment.

Temperature is an important part of the indoor climate when it comes to comfort and productivity. And to feel comfortable is a prerequisite for performing without hindrance. Both high and low temperatures can affect mental ability, work capacity, strength and mobility. This in turn can affect the frequency of accidents, work performance and comfort.
Volatile Organic Compounds or carbon-based chemicals are emitted as gases from solids or liquids. There are thousands of different gases produced from products like paint and perfume, but also generated from activities such as cooking and smoking. If exposed to VOCs, possible short-term symptoms and health effects may include headache, cough and dizziness as well as throat and skin irritation.
Relative humidity is a measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature. Both too much or too little relative humidity can cause discomfort. If you have really high humidity levels you may want to check your pipes and plumbing for water leaks. The optimal RH-level is between 40-60%.
Airborne particles are a form of air pollution, a piece of solid or liquid matter that floats in the air around us. Their ability to get stuck in the body and form depots depends on their size and whether they can pass through the mucous membranes of the airways. Some can enter the bloodstream and spread to other organs. A ventilation system can remove a majority of the particles from outside.
How does carbon dioxide indoors affect us, what is the recommended levels and how can we reduce too high levels? All of this and much more in the latest post in our blog series about good indoor air.
What constitutes good air? And how do we know if the air we breathe is good or bad? We have identified the level of carbon dioxide, particulate matter, relative humidity, volatile organic compounds as well as the temperature in a room as key factors. Thanks to digitization and sensor technique we can now measure most of these different parameters in indoor environments and visualize the invisible.
In a recent blog post, which you can read here, we talked about our ongoing steel journey and the offering of ventilation products in Recycled 75 steel. We also mentioned the fact that the world steel production is expected to increase from 1,950 million tonnes in 2021, to around 2,500 million tonnes in 2050. By then, 2050, the need for steel is expected to be covered by 50% with recycled steel, w
Lindabs journey toward reduced CO₂-emissions, first stop: decarbonised steel. In 2021, we partnered with SSAB on a future with fossil-free steel. And now, 2023, we have launched products in Recycled 75 steel.
Minimizing duct leakage is an underestimated energy-saving opportunity that can be achieved with no technical restrictions and with minimal effort. This has been well-proven through research, standards, directives, and legislation. It is crucial that the installer has the right education, awareness and that field measurements are performed to ensure minimum leakage and meeting the design values.
Lindab has installed one of Europe's best sound labs in Farum near Copenhagen. It has recently been expanded so that it can now be used for sound measurements on virtually all types of products. The laboratory is not only used by Lindab itself but also by external customers that require precise documentation of their products' sound attenuation/absorption, sound power levels, and pressure drop.
