#22 The Truth About Garage Door U-Values - Does Insulation Actually Matter

We all know the terminology. Insulated panels. Thermal performance. U-values. Thermal breaks. But how much do those numbers actually mean when you're standing in front of a customer's garage? And how do you know whether you're comparing garage doors properly? In this episode of the Garage Door Installers Podcast, James takes a proper look at the thermal performance of garage doors - from basic single-skin up-and-over doors through to insulated roller doors, sectional doors and side-hinged doors. Because the customer doesn't necessarily care that a door has a particular U-value. They care that their garage is freezing. They care that the room above the garage is cold. They care about making their garage more comfortable. And that's where understanding the product properly allows you to have a much better sales conversation. In this episode we cover: - What a U-value actually means - Why lower U-values represent better thermal performance - The difference between a panel U-value and a complete-door U-value - Why thermal bridging and seals matter - How different types of garage doors compare thermally - Real-world examples of heat transfer through a garage door - Why an insulated door doesn't automatically make a garage warm - When thermal performance really matters to a homeowner - Sectional doors and why they can offer excellent thermal performance - Insulated roller doors and the importance of looking at the complete system - Why side-hinged doors can produce very different panel and complete-door figures - How to avoid being misled by impressive-looking brochure figures - How installers can turn technical specifications into better sales conversations Got a topic you'd like us to cover? We're building the Garage Door Installers Podcast around the things that actually matter to people working in the industry.
