Old High Mill

Swimming Pool Glazing in North Yorkshire

Old High Mill is a substantial leisure‑wing extension added to a historic property near Bedale, North Yorkshire. The homeowners envisioned a bright, durable and low‑maintenance pool environment that balanced high‑performance glazing with the mill’s rural context. IQ Glass were appointed to design, engineer and deliver a comprehensive glazing package capable of performing in a chlorinated, corrosive and high‑humidity environment, while maintaining minimal sightlines and seamless architectural integration.

The final glazing composition brings together ultra‑slim sliding doors, large‑format structural glazing, frameless rooflights and aluminium windows, forming a singular, light‑filled volume that opens directly onto the surrounding terrace and landscape.

Design Context & Key Challenges

 
Pool halls present extreme conditions: moisture, temperature fluctuation, chlorine vapour and continuous condensation risk. The glazing specification required marine‑grade finishes, enhanced perimeter sealing, warm‑edge spacers and hardware specifically tested for corrosion resistance.

Due to the restricted mill site, installation required:

  • Specialist crane lifts for oversized units
  • Multiple revisits to coordinate sequencing with other trades
  • Adjustments to thresholds, drainage channels, and interface pressings to ensure performance in a pool environment.

IQ Glass Solutions Provided

The main pool elevation uses ultra-slim sliding doors to give wide, easy access for poolside circulation and summer ventilation. Selected assemblies were specified with a marine‑grade coating to withstand the corrosive atmosphere typical of chlorinated spaces. Thresholds, drainage and perimeter details were coordinated to keep lines clean while managing splash water.

Beyond the sliding openings, fixed structural glazing creates expansive picture windows with crisp glass-to-glass junctions that align with the roof geometry so the pool hall reads as a single, clear volume. Vertical panes are tied into the roof glazing with silicone‑jointed connections, maintaining an uninterrupted sightline from water level up into the sky, for this swimming pool glazing in North Yorkshire.

Daylight is brought deep into the plan by a ribbon of frameless rooflights arranged as single and multi‑pane runs. The roof glazing was detailed for pool‑specific performance, with warm‑edge spacers, robust perimeter seals and concealed support to manage humidity and reduce condensation risk while keeping the interior evenly daylit.

Elsewhere, Sieger HD aluminium windows provide controlled ventilation and emergency escape where required. Hardware and hinges were selected for resistance to chlorine, and opening lights incorporate trickle ventilation and cills to suit the pool specification without adding visual clutter to the elevations.

Performance Considerations

 
  • Chlorine resistance: All hardware, metalwork, and exposed aluminium coated and tested for corrosion resistance.
  • Thermal Stability: Solar‑control coatings and insulated glass units to reduce heat gain.
  • Condensation Control:
    • Warm‑edge spacers
    • Deep perimeter sealing
    • Frameless rooflights designed for humidity management
  • Durability: Key oversized panes were heat‑soak tested to reduce the risk of spontaneous breakage.

Quality and durability measures were built into the package. Key oversized panes were heat‑soak tested to reduce the risk of spontaneous breakage, and crane lifts were used to place units safely without compromising edge quality. All visible aluminium was finished in RAL 7021 for a coherent exterior that complements the mill context and surrounding landscape. The finished pool hall is a clear example of swimming pool glazing in North Yorkshire, combining transparency, resilience and precise detailing.
