Thermal insulation: three winning strategies from tennis

What if tennis explained good insulation better than a data sheet?

What if we told you that resisting, slowing down and sending back are not only tennis tactics but the three things that decide whether insulation genuinely works?

In this short, deliberately light-hearted video, tennis is used to make sense of:

• thermal resistance
• thermal lag
• heat reflection
• and why airtightness decides whether the comfort lasts

One simple comparison, plain explanations, and a concrete example with R'BULL insulation for a home that stays comfortable in summer and in winter.

Watch the video and win the match against thermal discomfort.
