Cardiff 1960s new-town house casement windows — Rosac survey & install
Owners solving the cold-bridge draught complaint that defines original new-town spec. That's the search intent behind most 1960s new-town house enquiries for casement windows out of Cardiff. Casement replaces the original sliding aluminium naturally — top-hung above fixed pane matches the visual weight of the original horizontal slider without the cold-bridge. The porch canopy fixings are usually one bolt into masonry and one into the fascia — we test both before removing the old door. Chimney breasts eat a foot of internal width on both sides — bay window quotes account for it in the survey. The rear garden extension pattern (added 80s–00s) usually holds the tired patio door — replace it as part of the same job. The two-storey bay carries loading from the roof valley — reinforced steel corner cores accept it without deflection. External foil cills are colour-matched to the frame — replace as a set or the elevation reads two-tone. Gable-end glass panes are often 2.4m+ tall; we deliver on a dedicated glass lift rather than by hand. Listed status is documented on the deed pack — we check before quoting anything other than like-for-like heritage spec. Foil colour choice on a semi is a shared question with the neighbour; matched pairs read cleaner than solo swaps. Concrete cills on post-war stock are cast into the wall; the frame sits on them without needing timber packers.
Common 1960s new-town homes problems we quote casement windows for
- 1Original 60s sliding aluminium frames cold-bridge and ice up internally.

Who's asking
Second-time buyers upgrading original new-town glazing, and long-time owners doing full-property refurbs for retirement.
In Cardiff specifically that reads as city professionals, young families in the suburbs, landlords with HMOs near Cathays Park. The recurring driver for a casement windows enquiry is: Owners solving the cold-bridge draught complaint that defines original new-town spec.

Our casement windows spec for a 1960s new-town house
Casement replaces the original sliding aluminium naturally — top-hung above fixed pane matches the visual weight of the original horizontal slider without the cold-bridge. In Cardiff we see this on the Edwardian and Victorian bay-fronted houses in Cathays and Roath, 1930s semis in Llanishen, modern builds in Pontprennau around Cyncoed, Llanishen, Roath, usually paired with heritage-friendly frame profiles in conservation streets; traffic noise on the A48 ring; single-glazed bays losing heat in tall Victorian rooms on the same elevation. 10 miles from base, A470 the whole way — Cardiff installs run as smoothly as our home patch. Council area is Cardiff Council in South Glamorgan; commercial neighbours include Cardiff Bay, Capital Business Park and the Llanishen industrial belt. Nearby: Penarth 4mi, Caerphilly 7mi, Barry 9mi. Local vibe: capital city — everything from Edwardian conservation-area bays to glass-fronted Bay apartments.
What we typically find on survey
- ·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
- ·The top vent has been kept permanently closed with a wooden shim wedged inside the frame.
- ·The composite door slab has a hairline crack along the letterplate cut-out from a delivery boot.
- ·There is a paint bridge from the internal architrave to the frame that will crack the moment the new unit lifts out.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
- ·A previous owner has fitted a chain to the front door on top of the multipoint — a sign they never trusted the lock.
- ·The gap under the front door has been carpet-strip filled from inside — the exterior weather bar is missing.
- ·The old timber sub-frame under the current uPVC unit is still in place and is soft at the bottom left corner.
- ·Every south-facing frame has visible micro-cracking in the surface film — early sign of UV embrittlement.
- ·The sealed unit is a 20mm gap, not the modern 28mm minimum, so U-values are into the mid-2s at best.
- ·The top hinge on the front door has torn its middle screw out and been left to run on two fixings.
- ·The bottom track on the sliding door has a build-up of grit that the rollers grind through every open cycle.
- ·The frame drainage slots at the bottom are clogged with debris, so rainwater sits inside the chamber.
- ·A homemade timber threshold has been screwed to the concrete cill in front of the patio door.
- ·One sash sits proud of the frame by 2mm along the top rail — a factory manufacturing tolerance that never got addressed.
- ·The Yale night-latch on top of the multipoint is a sign the resident does not trust the primary lock.
- ·The front door threshold weather-bar seal is missing its rubber blade and the metal channel is bent.
- ·Condensation runs down the inside of every north-facing pane between October and March.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·The reinforcement steel inside the top rail of a wide sash has rusted through in one corner.
- ·The middle mullion sags visibly across the top rail on any window wider than 1.6m.
- ·The composite slab has swelled by 2mm on the hinge stile from years of morning-sun exposure.
- ·The bathroom pane is patterned glass from the original build, and the pattern is no longer a current stock line.
- ·There is a permanent green algal streak below the sill where water is bypassing the drip groove.
- ·The multipoint lock still throws but the internal handle has 40° of dead travel before engaging.
- ·The internal beads pop out with a chisel and a tap, but the external glazing gasket is bonded solidly to the frame.
- ·There is no drip groove on the underside of the cill — water tracks straight back onto the brick face.
- ·The internal reveal plaster is spalling under the cill where condensation has run for years.
- ·One kitchen unit has a defrost trace across the low-e coating — the argon fill has been gone a while.
- ·The multipoint gearbox on the front door still throws, but the hooks miss the keeps by 2mm on the middle throw.

How we actually fit it
- ·The trickle-vent covers are set with their vane orientation matched across a bank of windows for visual consistency.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise, checked with a spirit-level lip.
- ·The frame reinforcement is chosen for the wind load exposure of the elevation, not the smallest steel that fits.
- ·Foam gets a wet finger dressed into the internal reveal, not a dry-cut strip that pulls back later.
- ·The perimeter tape between frame and reveal is a compressible foam tape, not a plain butyl strip.
- ·The frame perimeter sealant is a low-modulus polymer where the substrate is going to move — plain silicone otherwise.
- ·The letterplate is fitted with the internal flap set to close under its own weight without dragging.
- ·The cylinder key gets a keyring immediately, so it does not sit unnoticed in a jacket pocket for the day.
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·The lead fitter leaves a handwritten note of anything the client should watch in the first month, not a printed generic checklist.
- ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
- ·The old frame's fixing holes in the brick are filled and made good before the new outer frame beads up to the reveal.
- ·The threshold is bedded on butyl mastic under the outer skin, giving the fitter a second waterproof line behind the perimeter silicone.
- ·The client is left with the manufacturer's paperwork in a labelled envelope, not a folded receipt tucked inside a drawer.
- ·The internal trim goes on with pin nails through the flange, not straight through the visible face.
- ·The dustsheet inside the room is a heavy canvas taped to the skirting, not a light plastic left loose.
- ·The client is walked through the finished job with a printed operation card, not a rushed verbal handover.
- ·The friction stay screws are torque-limited, not driven at full trigger — over-driven screws strip the stay chamber.
- ·Cavity closers get inserted where the old frame's cavity closer has failed — not omitted because it is unseen work.
- ·The threshold sealant runs the full width with a single tool pass, not stitched together in inches.
- ·The keeps for the multipoint are set with a strike plate template, not marked by eye against the closed door.
- ·Ground protection sheet goes down before the old frame comes out — not after the mess starts.
- ·The bead-in tools are rubber-faced, not steel — a steel tool marks the profile within minutes.
- ·Fixings are set at the manufacturer's spacing, not evenly spaced by eye — the corner loads matter.
- ·The old keys are collected and destroyed, not left in a bag on the drive.
- ·The door is closed, locked, and left overnight before final adjustment, so any settlement is captured before sign-off.
- ·The client is walked through the operation of every lock, every vent, and every restraint before the crew leaves.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
- ·The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.

Lime plaster reacts to modern silicone with staining; we use low-modulus polymer at the perimeter instead. Wide walkways in front of the property give plenty of room for lifts and staging — no kerbside pressure. Around Cardiff that usually means heritage-friendly frame profiles in conservation streets on Edwardian and Victorian bay-fronted houses in Cathays and Roath, 1930s semis in Llanishen, modern builds in Pontprennau, with Cyncoed and Llanishen the streets we are on most. Single-skin wall means the frame carries no thermal break at the perimeter — sealant bead depth matters more than usual. Frame colour on the front elevation is often deed-restricted to white, cream or a heritage green in conservation areas. Salt air pits cheap aluminium at the fixing points; genuinely marine-grade powder coating resists. Original 60s sliding aluminium frames cold-bridge — you can feel a two-degree temperature drop within a foot of the glass in winter.
