Inwido Window Configurator App

The Problem

Inwido(, is one of Denmark’s leading window groups, and is part of Swedish owned Inwido AB, who are Europe’s leading providers of window and door solutions. The company provides its products through various channels, including direct sales, retailers, middlemen, small and large building companies, etc.

Ever since the beginning, the company functioned on a B2B model, but in the recent years they have been planning to reach out to and get in contact with the customers themselves.

Me and my team had to create a digital concept, which would generate leads for the company.

Qualitative research

Having a broad variety of people as target audience (people living in Denmark and owning a house), it was rather easy to find and talk to the right people. We interviewed people matching the profile. 

We found out that all of them have a hard time purchasing new windows, due to their lack of knowledge in the field. Furthermore, when the customers want to replace a  broken window, they are going to need a replica. In these cases it is crucial for them to see the product in real life.

Why a configurator app?

While the user styles his/her own window with a configurator, they get to know the supplier company’s available products and are able to see how the window would look with the chosen features. (Thus saving time on going to showroom and asking around)

Moreover, by completing a survey before using the configurator, the user will be recommended certain window types and features. 


The navigation of the web application is eased by using tabs for each step of the process. The user can quickly jump from one step to another if he/she wishes to. 

The user is able to hover and click on each part of the edited window. By hovering, they see which part is applied and by clicking, they get to the corresponding category. This solution helps the user edit specific parts faster, because they do not have to find the categories themselves.

When the user is done editing their window, the app gathers all information about the final product and compiles it into a brochure. The user can enter their e-mails and get the brochure sent to them right away. Thus, the solution additionally generates leads for the company.

Usability Testing

While prototyping, proper error prevention and clear naming were used. To find out how it works for potential users, Think-aloud tests were conducted. The goal was to find out, whether the interaction with the application is smooth enough and where can the application further improve.

Heuristic evaluation

A heuristic evaluation was conducted on the finished prototype based on Jakob Nielsen’s 10 Heuristic principles. All the team members named issues and recommendation regarding each principles and added a severity measure of 1 to 5. The results were discussed afterwards and last changes were made on the prototype.
