Structural Glazing & Slim Sliding Doors in North Wales

At IQ Glass, we provide bespoke architectural glazing solutions for one-off luxury houses across North Wales. Our designers pair advanced engineering with refined detailing to maximise natural light, frame sea and mountain views, and create effortless connections between interiors, terraces and gardens. From ultra-slim sliding doors and structural glass roofs to large picture windows and elegant steel doors, every system is specified for coastal durability, thermal performance and year-round comfort; perfect for architectural glazing in North Wales. 

We work extensively along the coast and islands, including Anglesey (Beaumaris, Menai Bridge, Trearddur Bay, Rhoscolyn), Conwy and Llandudno, Deganwy and Penrhyn Bay, and across the Llŷn Peninsula around Abersoch, Llanbedrog and Pwllheli. Homes here face salt-laden air, driving rain and sudden gusts; we design façades to thrive in these conditions with coastal-grade hardware and fixings, marine-grade finishes, and weather-tested junction details engineered to the site’s wind loads. Solar-control and low-iron options preserve clarity and comfort without dulling the seascape. 

Large-Format Glazing for Exposed & Hillside Plots

Clifftop and upland sites are a hallmark of North Wales and demand careful planning for oversized panes and double-height openings. We coordinate structural connections, deflection limits and wind-load checks with your engineer, then plan access, lifting and install sequences around steep drives and narrow lanes. Our crews use the right mix of cranes, vacuum glass lifters and mini spider cranes, scheduling deliveries to hit safe weather windows; so even very large panes reach site and slot in cleanly. 

Where wellness spaces are part of the brief (pool houses, saunas and garden gyms) we specify corrosion-resistant hardware and ventilation strategies that manage humidity without fogging or condensation. Wide openings with minimal sightlines keep the focus on views, while seals and thresholds are detailed for genuine weather protection in exposed locations. 

Planning, Heritage & Sensitive Settings 

North Wales includes conservation areas and protected landscapes, from historic townscapes in Conwy and Beaumaris to listed farmhouses across Gwynedd and the Llŷn AONB. Our approach is to make glazing read as calm and recessive: slim frames, balanced proportions and junctions that respect local stone and slate. We support your design team with the technical information and coordinated drawings they need, helping make planning and building control under Welsh regulations straightforward. For heritage-led projects, our refined steel-look systems deliver today’s airtightness and thermal targets while respecting character. 

Comfort, Thermal Performance & Acoustics

 Minimal aesthetics only work when performance is robust. We pair slender sightlines with excellent U-values, airtight installation and proven weather testing. Along the A55 corridor or on exposed headlands, acoustic laminates and, where appropriate, triple glazing keep interiors quiet; on bright west-facing façades we balance g-values, shading and ventilation to control summer gains. We provide dynamic overheating assessments to meet current Welsh regulatory requirements and deliver comfortable, efficient homes through all seasons. 

 

Detailing That Belongs to North Wales

Materially, we lean into the region’s character: crisp glass junctions against local stone, deep-set frames within slate reveals, structural glass links that bring daylight into traditional plans without visual clutter. For contemporary replacements and exceptional one-off homes, we use structural glass walls and roofs to create pavilion-like living spaces; clean, coastal and timeless. 

Areas We Cover 

Our specialist teams deliver architectural glazing across Anglesey, Conwy, Denbighshire, Flintshire and Gwynedd, including the Llŷn Peninsula and inland toward Eryri. Whether you’re remodelling a period house or building a new coastal retreat, we tailor the specification to your site.
