Ventilation and indoor climate of the future

By Nicklas Friberg, November 14 2018


In the past few years, the general public's interest in and knowledge of ventilation and air quality have increased. At the same time, major players on the market have started to understand that customised indoor climate solutions lead to great energy savings. Demand-driven ventilation is becoming more and more sought-after while the products have evolved and become more intelligent with new features. In the future, the public is predicted to become more interested in air quality and indoor climate, and knowledge also comes with a set of requirements.

In this blog post you can read my thoughts and ideas on how we will look at ventilation in the future.

How to choose a diffuser?

By Johan Land, October 31 2018


We all have our individual preferences in life and that certainly also counts for the indoor climate. The most visible part of a ventilation system is the diffusers making sure the air is distributed as gently and comfortably as possible, but which one should you choose?

What is a typical day of a ventilation installer like?

By Daniel Tingvall, October 17 2018



The duties of a ventilation installer are varied and challenging. As well as installing ventilation products, logistics and cooperation with other players in the construction process are an important part of the day’s work. I met ventilation installer Oscar Macaya (on the right in the photo) one morning on a construction site in the south of Stockholm to talk about his daily work.

How ventilation can facilitate the maritime green shift

By Michael Båring, August 31 2018

While climate has become a top priority in most industry sectors, the maritime green shift has been a slow-starter. However, with rising fuel costs there is a growing need to reduce energy waste. Installing high quality air-tight ventilation systems on ferries and cruise ships is one central measure to lower the use of energy in the maritime sector while at the same time reducing emissions and saving money.

High demand for energy efficiency improvements

Maritime is inevitably the most energy efficient way to transport goods and people. To reach the climate targets set by the EU, transport volumes will increasingly have to be transferred to sea-based alternatives. At the same time, as the cost of fossil fuel keep rising there is also an increasing need for the maritime sector to adopt new techniques, alternative fuels and work to increase energy efficiency.

The need for innovation is driven by economic logic, but increasingly by political pressure too. The Norwegian parliament for example recently passed a resolution to halt emissions from cruise ships and ferries in the Norwegian fjords as soon as technically possible and no later than 2026. Similar decisions will probably follow in other parts of the world in the years to come.

Distribution, the Good thinking way

By Dag Jarlson, May 18 2018


Adapting to changing customer behaviour is essential to stay ahead. With a new distribution concept, we aim to improve availability and speed of delivery while at the same time reducing the total need for transportation.

Demand for just in time deliveries is rising steadily. Customers place smaller orders more frequently than before and expect faster and complete deliveries. This is off course nothing to be surprised about. Minimising storage is key to lowering costs and on many construction sites for example there simply isn’t room for storing components. Lindab noticed this development early on and in 2013 we decided to analyse our entire distribution process in the Nordic countries. That work resulted in a new strategy which aims to make Lindab the frontrunner of availability and efficient distribution.

Corrosivity classes and warranties – a jungle to master

By Zeina Lindström, May 07 2018


It is easy to get dazzled by marketing campaigns with products that can handle the toughest environment when it comes to corrosivity (C5). Many believe these products have to be the best and that you really get quality products in place if you were to mount these.

What many people do not know, is that to technically be able to say that a product fulfills C5, the standard only demands 2 years of testing. If the product is approved after these 2 years, you can brand the product with the C5 standard. This becomes a bit irrelevant and meaningless, unless you are pleased with the product lasting for only 2 years of course. 

First you have to figure out what the environmental preconditions are, which corrosivity class, you are about to mount a product in (there are tables available with examples of environments in C1 to C5) and then check how long the warranty period is in that particular environment. It happens that technical data sheets state one thing, but when you check the warranty, it can actually exclude the environment that is used in the marketing campaign. What then happens is that you get a crash between the standard (2 years) and the warranties, where anything between 10-50 years can apply.

Roof drainage – much more than protection

By Caroline Svensson, March 27 2018


More rain increases demand on quality roof drainage systems, but also creates opportunities for new smart solutions.

Climate change is expected to lead to longer dry periods in Europe, but also a higher intensity of rain and snowfall. Daily precipitation could increase by 35 per cent during winter in most parts of Europe during the 21st century, according to the European Environment Agency. Although Europe is by no means unfamiliar with heavy rainfall and flooding, the projections do underline the need for safety measures to protect buildings from water damage and economic loss.

Protecting by connecting

By Enrico Audisio, March 19 2018

The cost of fires can be measured in lost lives, injuries and economic losses. By reaping the benefits of technological advance, fire protection can go from a reactive operation to an active. That will safeguard the value of our buildings – and protect lives.

Fire bear a huge price on society. The annual cost of fires in Europe is estimated to a staggering 126 billion euro each year, according to Fire Safe Europe, an organization committed to strengthening fire protection across the EU. More important, fire causes injuries and claim lives. While approximately 70,000 people in Europe are hospitalised with severe fire-related injuries each year, about 4,000 people are killed by fire during a year.

BIM – Digital transformation in practice

By Henrik Bengtsson, February 07 2018


While the term digitalisation often comes across as a bit abstract, the digital transformation in companies like Lindab is both real and concrete. Building information modelling, BIM, for example is a methodology that is revolutionizing the way new buildings are planned and constructed.

Constructing a modern building is a complex process full of potential pitfalls. If the various members in a project fail to find a common understanding, the entire venture risks taking more time than expected and costing more money than estimated. This is true regardless if we are talking about the construction of a private house, a school or a commercial building.

A certified step towards sustainability

By Torbjörn Bruzelius, January 31 2018


Lindab has managed to fulfil the highest criteria and is now certified by Eurovent for our duct systems Lindab Safe and Lindab Safe Click. I hope this recognition of our work will raise the overall production standards of ventilation and take us one step closer to a more sustainable future.

According to the EU, buildings are responsible for 40 per cent of all energy consumption in the member states. Ventilation is one important contributing factor and in any building, whether it be a school, a commercial property or a private house, the ventilation system constitutes approximately 30 per cent of the total energy consumption. Even though ventilation requires energy to work, poorly functioning systems often lead to unnecessarily high consumption. Duct systems that have not been assembled in a correct manner or fittings that do not fit are reoccurring problems that result in air leakage and high costs.
