Mariners Court

The SA1 Waterfront development has without doubt become one of South Wales’ most enviable places to live. The main focal point is the vast expanse of water, Prince of Wales Dock, surrounded by quality residential and ongoing commercial developments that plan to serve the new growing community including restaurants, bars, retail, leisure and educational facilities.

Situated in a pedestrian-friendly environment of SA1, the Mariners Court scheme saw the construction of 79 spacious one and two bedroom modern apartments, in two blocks of five and three stories, created specifically with the over 55’s in mind.

A 25mm cavity was formed on the outside of the timber frame structure using timber battens, which was then encapsulated with 10mm sheathing boards onto which a layer of Wetherby Expanded Polystyrene in 30mm and 120mm thickness were fixed. Slip joints were added at each floor level to compensate for potential movement in the timber structure and Mineral Wool fire breaks were also added at each floor level to prevent potential spread of flame.

A layer of K&A basecoat and alkali resistant reinforcing mesh was then applied to the insulated render system which was finished using white and blue Wetherby Silicone 1.5mm ‘K’ decorative render. The final U-value achieved was a very respectable 0.14 W/m²K.

Due to its striking colour, Mariners Court is a very prominent feature on the entry route into Swansea.
