Secondary Glazing in Deepcar, Sheffield
Most of the Deepcar housing stock is 19th-century stone cottages and terraces with stone-mullioned casements. It isn't formally protected but the era of the stock makes replacement double glazing awkward and expensive. A room-side secondary system is the standard answer.
What Deepcar homes typically need
Stone-built valley village on the Don.
Typical window: stone-mullioned casements.
Most common brief: cold deep reveals and damp corners in solid stone walls.
Deepcar isn't formally protected, so we can spec on performance alone — Low-E soft-coat glass and 6.4 mm laminated as standard.

Common questions
Can Low-E glass be combined with acoustic laminated?
Yes — most heavy specifications combine both, so you get acoustic gain and thermal gain in the same install.
How is the quote calculated?
We survey and template every opening on site, then quote in writing per opening — no per-square-metre pricing that hides oversize charges.
Is there a warranty?
Yes — 10 years on the manufacture and installation, and a manufacturer's warranty on the glass units.
Can I still open the original window?
Yes — every sliding, hinged and lift-out unit is designed to move clear so you can operate the primary window behind it.
How does this compare to replacement double glazing?
A modern secondary unit with Low-E glass and a 100 mm cavity outperforms most existing sealed double-glazed units — and it works on windows you legally can't replace.
