Secondary Glazing for Churches
Historic churches carry the country's most fragile and most valuable stained glass — and the highest heat losses of any building class. The most common question we get is: "Will it damage the stained glass?" — the short answer is on this page, alongside the technical detail.
Standard spec for churches
Slim satin profiles finish invisibly behind stained-glass tracery.
A room-side pane shields historic glass from thermal shock — the leading cause of stained-glass cracking.
Faculty and listed-building consent packages included free with every quote.
"Will it damage the stained glass?"
Our slim profiles have installed behind Grade I stained glass in three Sheffield churches without a single reported issue.

Common questions
Will the frame be visible from outside?
No — the entire system sits room-side of the original window. From the pavement your frontage looks unchanged.
Do you fit around live commercial operations?
Yes — hotels, offices and restaurants routinely book out-of-hours or overnight installs so trading isn't affected.
Do you supply the acoustic performance data insurers ask for?
Yes — every acoustic-specified install ships with a performance report you can hand directly to an insurer or building-control officer.
How long does an install take?
A typical whole-house residential install is a single day; larger commercial jobs are phased so trading isn't interrupted.
Is there a warranty?
Yes — 10 years on the manufacture and installation, and a manufacturer's warranty on the glass units.
