Thermal Insulation in Pitsmoor, Sheffield
Hillside Victorian stock overlooking the city: that is Pitsmoor, and it shapes how we spec thermal insulation here. Around Pitsmoor Road the openings are sashes with decorative heads. Most enquiries here come from owner-occupiers doing one or two rooms at a time, so we price per opening rather than per house. We cover S3 continuously — Pitsmoor sits within reach of the Ring Road (A61), which is also the reason a lot of these calls are about noise.
How we would spec this
| Service | Thermal Insulation Secondary Glazing |
|---|---|
| Performance target | U-values from 1.868 W/m²K |
| Recommended product | vertical-sliders |
| Best fit windows | Original single-glazed sashes, Steel-frame Crittall-style windows, Leaded-light casements, Stone-mullioned windows |
| Local window type | sashes with decorative heads |
| Common objection | Wouldn't full double glazing be warmer? |
Survey notes from the area
A properly sealed secondary glazing unit with Low-E soft-coat glass reaches U-values as low as 1.868 W/m²K — comfortably meeting current retrofit building-regs requirements.
Because the primary window stays put, the whole retrofit sidesteps the historic fabric damage caused by ripping out old sashes.
Openings in Pitsmoor are typically sashes with decorative heads, so we template to the reveal rather than assuming a standard size.
Pitsmoor carries no conservation designation, so the specification is decided purely on performance.
A modern secondary unit with Low-E glass and a 100 mm cavity actually outperforms most existing sealed double-glazed units — and it works on windows you legally can't replace.
We will tell you when secondary glazing is the wrong answer — it happens, and it saves everyone time.
Aluminium systems are powder-coated to any RAL colour at no extra lead time.
Cavity depth does more for acoustic performance than glass thickness, and we design for it first.
We survey with a sound level meter where noise is the driver, so the target is a number rather than an impression.

Common questions
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.
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.
Will it help with condensation on my sash windows?
Almost always — the room-side pane raises the surface temperature of the glass you touch, which stops warm interior air condensing.
What U-value can secondary glazing achieve?
As low as 1.868 W/m²K with Low-E soft-coat glass and a 100 mm cavity — comfortably meeting current retrofit building-regs targets.
Can we do one room now and the rest later?
Yes. We template and price per opening, so a later phase is quoted at the same rate — there is no penalty for splitting the work.
Will it get in the way of curtains or blinds?
Rarely. Reveal-fixed units sit inside the existing recess; where the recess is shallow we face-fix and reposition the blind, which we flag at survey rather than on the day.
