Thermal Conductivity

Thermal conductivity measures how effectively building materials conduct heat. This article explains the significance of thermal conductivity (λ), its measurement using standards like ISO 8301 and ASTM C518, and how moisture can affect insulation performance. Understanding these factors is essential for energy-efficient building design.

Navigating Water Vapour Diffusion in Building Materials

Moisture management in buildings requires a deep understanding of the sd-value and MNs/g. These metrics help determine how materials resist and transmit water vapor, which is crucial in preventing condensation and structural issues. Learn how these values can guide better material choices for long-lasting, healthy buildings.

Sun protection glass: the glazing decision that stops your home becoming a greenhouse

A well-insulated window keeps heat in. A solar control window keeps unwanted heat out. These are different problems with different solutions — and confusing them is how beautiful north-facing glazing turns into an unusable room by November. Here's how to think about it.

Heat transfer and glass: why modern windows aren't the weak spot everyone thinks they are

Glass has a reputation as the thermal weak link in any building. That was fair in 1985. Here's what's actually inside a modern glazing unit, how much performance has improved, and what to look for when you're specifying or comparing windows.

Decarbonising Buildings Part 3: Is carbon actually the right metric to measure progress?

Policy and regulation are what turn good intentions into industry-wide change. But the carbon metrics driving that policy have real strengths — and some honest limitations. Here's what they capture, what they miss, and why the distinction matters.
