Glass Wiki
Laminated, toughened, low-iron, self-cleaning glass and specialist coatings.
Spontaneous breakage of toughened glass can look like an explosion — often caused by nickel sulphide inclusion, edge damage or installation stress. This reference explains common causes, how to tell them apart and what to do next.
Laminated glass reduces UV transmission but does not block it entirely. This reference explains how PVB interlayers filter ultraviolet light, what protection you can expect for furnishings and people, and limits of overhead glazing.
No — toughened glass cannot be cut, drilled or altered after heat treatment. This short reference explains why, what happens if you try, and how to avoid costly mistakes on site.
Self-cleaning glass uses a photocatalytic coating to break down organic dirt and a hydrophilic surface to help rinse it away. This reference covers how the technology works, realistic expectations and suitability for roof lights.
Low emissivity (low-E) coatings reduce heat loss through glazing by reflecting long-wave radiation. This reference explains how low-E works, hard vs soft coat, U-values and what to specify on roof lights for Part L compliance.
Low iron glass reduces the green tint of standard float glass and increases light transmission — useful for roof lights where clarity and daylight quality matter. This reference covers composition, performance trade-offs and when to specify it.
Laminated glass bonds two or more panes with an interlayer so the assembly stays together if broken. Essential for overhead glazing, balustrades and security applications — this overview covers construction, standards and roof light specification.
Toughened glass is heat-treated safety glass around four to five times stronger than ordinary annealed glass of the same thickness. Learn how it is made, where it is used in roof lights and why it shatters into small fragments when broken.
