Casement glazing in Kimberworth, Rotherham
Casement glazing in Kimberworth is common for a simple reason: the area is victorian terraces and interwar semis, and side-hung opening lights on hinges, often with a fixed pane and a top-hung vent is exactly what that period built. The problem we are asked to solve is the opening light and the handle furniture project into the reveal, so clearance has to be designed in. Kimberworth is not a conservation area, so the decision is purely technical rather than a consent question. Most enquiries here come from owner-occupiers doing one or two rooms at a time, so we price per opening rather than per house. Our vans are in Rotherham most weeks; Kimberworth is roughly 1.5 miles out from the centre, comfortably inside the South Yorkshire coverage area.
Aluminium systems are powder-coated to any RAL colour at no extra lead time.
Every opening is templated on site — we do not price secondary glazing by the square metre.
Cavity depth does more for acoustic performance than glass thickness, and we design for it first.
Glass specification is decided after the survey, not before — the same room can need two different thicknesses.
What goes in, and why
| Window type | side-hung opening lights on hinges, often with a fixed pane and a top-hung vent (found across every period, dominant in interwar and post-war housing) |
|---|---|
| Underlying problem | the opening light and the handle furniture project into the reveal, so clearance has to be designed in |
| System we fit | hinged secondary units, or lift-outs where the original is rarely opened |
| Glass specification | 4 mm Low-E as standard, 6.4 mm laminated on road-facing elevations |
| Measurement | we record handle and stay projection at survey because that dimension, not the glass, sets the cavity depth |
| Heritage position | on interwar stock the casements are usually not protected, which widens the specification options |
Local detail that changes the job
Casement leakage concentrates at the meeting stile and around worn hinge packings, both of which a single sealed secondary panel bypasses entirely.
Handle and stay projection sets the minimum cavity, so we measure hardware rather than assuming a nominal gap.
Kimberworth stock is Victorian terraces and interwar semis and the prevailing glazing is sashes and casements, which is why casement glazing comes up here so often.
We record handle and stay projection at survey because that dimension, not the glass, sets the cavity depth.
Kimberworth carries no conservation designation, so the specification is decided on performance alone.

Common questions
Will the secondary unit foul the casement handle?
Not if the cavity is set from the hardware projection, which is what we measure on survey. It is the most common cause of a badly-fitting retrofit elsewhere.
Hinged or lift-out for a casement?
Hinged if you open the window regularly, lift-out if you do not — lift-outs are slimmer and cheaper but need somewhere to store the panel.
Can you cover a fixed light and an opener together?
Yes, usually with a two-panel unit so the opener stays accessible and the fixed light is sealed.
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.

Send a photo of the window — with side-hung opening lights on hinges we can usually tell you the likely system before we visit.
- Step 2
Survey in Kimberworth: we record handle and stay projection at survey because that dimension, not the glass, sets the cavity depth.
- Step 3
Manufacture to the templated sizes with your chosen finish.
- Step 4
Room-side install with no external access and no alteration to the original frame.
Room-by-room in Kimberworth
Casement glazing in Kimberworth — the short version
The opening light and the handle furniture project into the reveal, so clearance has to be designed in. We fit hinged secondary units, or lift-outs where the original is rarely opened with 4 mm Low-E as standard, 6.4 mm laminated on road-facing elevations, templated to your opening. A single hinged panel seals the whole opening including the fixed light, which is where most of the leakage actually is.
