A Coastal Retreat Defined by Slim Sliding Doors in Mawgan Porth

Slim Sliding Systems Framing the Landscape 

To articulate the primary living space, IQ Glass installed a triple glazed slim sliding door system measuring 7m wide and 2.7m tall. Two fixed outer panes support two bi‑parting central panels that slide over the fixed units, opening the social space directly to the upper terrace and coastal panorama. Above this elevation, a frameless structural glass wall mirrors its width and height, formed from four triple glazed panes with silicone joints to create a continuous transparent façade.  

Across the main house, IQ Glass supplied three additional sets of slim sliders measuring 3.6m by 2.7m in a two track, three panel configurations. These units provide the central sliding leaf with two fixed outer panes, ensuring uninterrupted views while allowing flexible access. On circulation routes, IQ designed slim sliding pocket doors, including a 1.3m by 2.7m door that disappears into a wall cavity and a 1m by 2.7m pocket door positioned within the outer structure. These pocket systems help maintain clear wall lines while providing step free routes between internal and external spaces. 

Pool House Opening, Structural Transparency and Coastal Performance 

To the pool house and guest annex, IQ Glass supplied multiple sets of slim sliders measuring 1.8m by 2.7m in a two track configuration, with one sliding panel meeting a fixed pane. This provided a robust yet minimal coastal‑grade solution for a high humidity environment while opening the façade fully to the jacuzzi terrace and pool deck.  

A variety of aluminium casement windows complement the sliding systems, including top‑hung windows sized for ventilation and letterbox‑format openings designed to maintain privacy. These include units at 0.4m by 0.4m, 1.3m by 0.5m, and 1.3m by 1.1m. Multiple casement doors were supplied at 1m by 2m, 1m by 2.7m and 0.9m by 2.7m, two of which incorporate external timber slatted finishes to manage shading. All glazing not specified as triple glazed was delivered in double glazed low e units filled with argon gas for thermal performance.
