Columns & Capitals

Design Options for Polystyrene Columns and Capitals

Polystyrene column surrounds are lightweight architectural mouldings designed to enclose existing structural posts and create a more substantial, finished appearance. They can be used around entrances, verandahs, patios and other exterior areas to add proportion, definition and architectural detail.

Capitals are decorative elements fitted at the top of column surrounds. They help create a considered transition between the column and the structure above and can be designed to complement traditional, Hamptons, Queenslander or contemporary architecture.

Thermatech manufactures column surrounds and capitals from high-density expanded polystyrene (EPS), finished with a durable exterior coating. Profiles can be custom-made in round, square, tapered and fluted styles to suit the dimensions and design requirements of each project.

Benefits of Lightweight Polystyrene Columns and Capitals

Lightweight EPS column surrounds and capitals offer several practical design and installation advantages:

• Designed to Enclose Structural Posts: Column surrounds are manufactured in sections to fit around suitable existing timber, steel or masonry posts. They are decorative components and are not intended to provide structural support.
• Lightweight Construction: EPS components are significantly lighter than comparable solid concrete or masonry features, making them easier to transport, handle and position.
• Durable Exterior Finish: When correctly installed, sealed and painted, Thermatech mouldings are designed for exterior applications and provide a durable, low-maintenance decorative finish.
• Custom Design Options: Columns and capitals can be manufactured in a variety of shapes, sizes and profiles to complement different architectural styles and project requirements.
• Consistent Architectural Detailing: Custom manufacturing allows column surrounds and capitals to be sized and repeated consistently across entrances, verandahs and building elevations.

Straightforward Installation for Experienced Trades

Compared with heavy masonry features, lightweight EPS column surrounds and capitals are generally easier to transport, position and install. Installation should be completed by suitably experienced tradespeople using appropriate access equipment, approved adhesives and good building practices.

1. Project-Specific Manufacturing: Components are produced to suit the nominated post dimensions and selected architectural profile.
2. Sectional Installation: Column surrounds are supplied in sections that can be assembled around suitable existing structural posts.
3. Jointing and Finishing: Sections are aligned, fixed and properly jointed to create a consistent finished surface.
4. Ready for Painting: Once installed and appropriately prepared, the finished mouldings can be coated with a suitable exterior acrylic paint intended for masonry surfaces.
