A healthy mind in a healthy body is important. We all know that. In order to achieve this, our homes must be a healthy place to live in. That is why this blog focuses on the indoor climate of your home and on how you can improve it.

The quality of the air inside our homes is very often not healthy. Studies show that the air outside is often healthier than the air indoors. A bad indoor climate can contribute to various health issues such as headache, skin disease, sleeping troubles, asthma etc.

Remember that, living and working combined, we spend 90% of our life indoors. Which makes it all the more important to have a good interior climate in our home and at the office.

What do you need to look out for if you want to have healthy air indoors?

Insufficient ventilation and too much heat are the two main issues which affect the climate inside buildings. They result in polluted air and a stuffy indoor climate. You should, therefore, attach sufficient importance to ventilation and to proper regulation of heat and light.


Good ventilation is key to a healthy indoor climate. That does not mean that you need a state-of-the-art ventilation system in your home. How much ventilation is required depends among others on the thermal insulation and on the airtightness.

New buildings bank a lot on insulation. They typically also have big windows and, hence, there is a lot of sunlight and sun warmth inside the house, which requires adequate ventilation. With renovated older houses, the issue may be smaller and a more modest ventilation system will often do.

Built-on roller shutters with a ventilation grid

A practical solution to ventilate your home is to install built-on roller shutters with an integrated ventilation grid. Wilms has developed Rolvent®, built-on roller shutters with the ventilation grid incorporated in the roller-shutter box.

The grid remains invisible from outside. You can set it in five different positions and thus obtain an adjustable ventilation at all times, even when the roller-shutter is closed. The system is windproof and waterproof and can be mounted on practically all types of windows.

Adjusting light and heat

The amount of sunlight entering the house also has an impact on the indoor climate. If there is not enough sun, the house may be cool inside. That is all right in Summer, but less so in Winter. Too much sun entering the house can become a nuisance, too. Many modern houses are so well insulated that they quickly overheat.

Roller shutters or screens with light and temperature sensors

A practical solution against overheating are roller shutters or screens which open or close triggered by a light or heat sensor. This is very convenient for people who are less mobile and may find it difficult to operate their roller shutters. It is also a good solution if you are away during the day and do not want to come home to an oven in the evening.
