The things about glass
nobody explains.
A technical data sheet with every quote, a glass suggestion based on your needs, samples on your desk and one technical contact for all your projects.
Solar control, acoustics, safety, regulations and selection guides.
Why ground edges on insulating glass?
Thermal stress breakage always starts at the edge. That is why we grind every pane that goes into a unit.
ReadUg versus g-value: why standard triple glazing does not solve summer
Why Ug alone is not enough for summer and what does the job, with figures for our triple-glazed units.
ReadWhat the numbers on glass mean
Ug, g, LT, Rw, Ψ, EN 356 and the other values you see on a quote or a technical data sheet, each in brief.
ReadInsulating glass units: installation, sealants and storage
Why acetoxy silicones must not touch the unit, rebate drainage, storage and transport.
ReadHow to reach Rw 42 dB on a window next to a road
Asymmetric panes, acoustic PVB interlayer, cavity width. What actually works.
ReadToughened glass: roller waves, spots and other things that are not defects
Waves in reflections, rainbow spots under polarised light, bow. What is normal, what EN 12150-1 allows and how to choose glass so that it shows least.
ReadToughened or laminated? When to choose which?
Impact, falls, break-ins, fire. A short guide by application, with EN 12600 classes.
ReadEPBD 2024: what the new directive asks of the building envelope
Limit values, the energy performance certificate and the role of the g-value in the calculation.
ReadA technical data sheet
with every quote.
For every insulating, laminated or toughened glass configuration, we send a technical data sheet with Ug, g, LT, Ra and Rw values to EN 673 / EN 410, from the calculator. On request, a BoQ item description too, ready to paste in.
- Technical data sheet with the quote, no waiting
- Ug, g, LT and Rw for fifteen make-ups, right here on the site
- BoQ item description on request
- BIM file for the glass on request, for your building model

Build your own insulating glass unit
A few questions: which way the windows face, large or small, and what matters to you. The tool suggests the glass.
Answer the questionsOrder a sample
Tell us which samples you would like and your office address: solar control, acoustic laminated glass, balustrade glass, satin and decorative glass. We send samples by post.
