Featured in this case study: Construction, Qualitative, Business to business (B2B), Brand tracking, Advertising effectiveness
Saint-Gobain Glass commissioned DJS Research to explore market perceptions of its Planitherm product.
The primary objective was to understand the market’s views on the product, determine the most effective positioning, and identify the most compelling way to communicate the product proposition.
A key component of this project was the qualitative testing of the effective of the advertising concepts.
Concept advertisements were tested qualitatively with respondents in the North and South of England.
A total of 19 depth interviews were conducted, 10 in the South and nine in the North, each lasting 20–25 minutes.
All participants had recently purchased double glazing or were considering purchasing new windows.
Respondents were prompted to provide feedback on:
The ability of the ads to grab attention.
Clarity of the ad messages.
Differentiating qualities of the ads.
Relevance of the ads.
Motivating qualities of the ads.
DJS Research provided Saint-Gobain Glass with clear conclusions and actionable recommendations, identifying the most effective advertisement concepts, images, and language styles for communicating the Planitherm proposition.
"DJS Research have never let me down, and in recent projects they have pulled out every stop imaginable to get the job done within ridiculously tight timescales. I always know that if I work with DJS Research I will get results and recommendations that are accurate and actionable, with creative presentations and analysis."

At DJS Research, our researchers have a wealth of experience moderating qualitative research, putting research participants at ease and exploring experiences, attitudes and behaviours to unlock those ‘golden nuggets’ of insight.

We develop a bespoke approach to meet each client’s objectives, but some commonly used methods in our qualitative toolkit include:
We draw on behavioural science to understand why people do what they do, not just what they say they do. We go beyond a basic question and answer format to examine the all-important context for decision-making, for example spending time with participants at home, observing their day-to-day life or asking them to complete a diary. We consider the behavioural biases at play and apply relevant frameworks or models to guide our analysis and recommendations.
Ultimately, by uncovering and sharing real life stories and applying our knowledge of human behaviour, we deliver deeper insights that impact our clients’ decision-making.
