Glazing and Glass Performance
Windows are the weakest wall.
Modern glass fights back.
Find your footing with modern glass — what it can do for comfort, quiet, safety and efficiency — and specify glazing that earns its place instead of apologising.
Glass specs turn from jargon into your quiet strength.
- Decode glass specs — read performance data sheets without your eyes glazing over
- Balance light and heat — choose glazing that brightens rooms without cooking them
- Design for quiet — use glass build-ups that keep noise where it belongs
- Specify glass safely — know exactly where toughened and laminated glass are essential
- Cut energy waste — understand coatings and cavities that keep comfort affordable
- Question suppliers sharply — challenge quotes and technical claims with genuine understanding

A few hours from now, you could already see differently.
Glass specification was a list of coatings I pretended to understand. Learning U-values, g-values and the trade-offs between daylight, heat and glare gave me an actual decision framework. I now choose glazing to solve problems instead of copying the last project's spec.
Simple by design.

Answered simply.
Glass specs are alphabet soup to me — will this decode them?
Completely. U-value, g-value, low-e, laminated versus toughened — each becomes a decision you understand rather than a code you copy.
Will this help balance daylight against overheating?
That trade-off is the heart of the course, so your glazing choices serve comfort and energy instead of fighting them.
Do I need any prior experience?
No. Every course starts from where you are and builds up step by step, in plain language.
Is this software training?
No — software changes yearly. The thinking you learn here lasts a career.
How does it work?
Short video lessons with a small practice task after each. Any device, your pace.
