Glass & Glazing

Specialist glass and glazing systems engineered for performance — warmer rooms, quieter homes, safer openings and lower bills, year after year.

The Glass

Self-cleaning Glass

Self-cleaning glass is coated with a microscopically thin layer of titanium dioxide that does two clever things at once. Daylight (specifically UV) breaks down organic dirt — leaves, bird droppings, atmospheric pollution — on the surface; and the same coating is hydrophilic, meaning rainwater spreads out as a thin sheet rather than droplets, washing the loosened dirt away cleanly without streaks.

Why It Matters

Cleans Itself With Daylight & Rain

It's the natural choice for any glass that's hard to reach or expensive to clean — conservatory roofs, roof lanterns, large picture windows, upper-floor windows and oversized glazed gables. The coating works automatically every time it rains, so the glass stays consistently clearer for longer with no maintenance from you.

  • Titanium dioxide coating breaks down dirt
  • Rainwater washes residue away cleanly
  • Reduces window-cleaning frequency dramatically
  • Ideal for roofs, lanterns & upper floors
  • Compatible with Low-E and double-glazed units
  • Permanent coating — never wears off

Coating, Not A Compromise

The self-cleaning coating doesn't affect thermal performance — sealed units perform in line with standard double or triple glazing. Combined with Low-E coatings on the inner surface, A and A+ BFRC ratings are achievable while keeping the glass cleaner for longer.

How To Verify

Ask whether the self-cleaning glass is paired with a Low-E coating in the sealed unit, and check the BFRC rating on the complete window. Confirm the coating is fused to the glass (not a film or spray applied later).

Self-cleaning Glass — common questions

Yes — the coating noticeably reduces how often the glass needs manual cleaning, particularly on overhead or hard-to-reach surfaces. It doesn't mean the glass never needs cleaning, but it dramatically extends the time between cleans and prevents heavy build-up.
It works best in locations that get direct UV light and rain — most outdoor glass. In heavily shaded or sheltered spots (deep porches, covered patios), the coating is less effective because it needs both UV and rainwater to do its job.
Titanium dioxide — a common, safe substance also used in sunscreen, food colourings and paints. The coating is fused to the glass surface during manufacture, so it doesn't release into the air or environment.
No — it's permanently bonded into the glass surface during manufacture, not applied as a film or paint. The coating performs for the lifetime of the glass.
Yes — typically 15-30% more than standard glass. The premium is well justified for hard-to-reach installations where the saving in cleaning costs (or risk of ladder work) quickly pays back. It's also a sensible upgrade for skylights, lanterns and roof glazing.
Yes — self-cleaning and Low-E coatings are applied to different surfaces of the glass, so a sealed unit can have both. We typically recommend this combination for roof lanterns and conservatory roofs, where you want maximum thermal performance and minimum maintenance.
