Plastic architraves

Modern plastic architraves, commonly made from UPVC, are used to frame doorways, windows, and other internal junctions where clean lines and durable finishes are needed. These mouldings are lightweight, moisture-resistant, and quick to install, making them a practical alternative to traditional timber architraves. Plastic options avoid common issues like warping, splitting, or rot, particularly in high-humidity areas.

UPVC architrave products are available in pre-finished colours or plain white for on-site decoration. Builders typically use them for internal door frames, window reveals, or to conceal junction gaps between plasterboard and structural openings. Adhesive fixing or pinning to timber grounds is standard practice, depending on the surface. Whether you're working on a full refurb or a single-room fit-out, plastic architraves offer a low-maintenance option.

Plastic architraves - FAQs

1. What’s the difference between timber and UPVC architraves?

UPVC architraves are made from plastic, offering better moisture resistance and less maintenance than timber. Timber may require sealing or painting and may be more prone to movement over time.

2. Can I paint over a plastic architrave?

Yes, most plain white UPVC architraves can be painted with a suitable primer and topcoat. Pre-finished options are typically left as-is.

3. How are plastic architraves installed?

They’re usually fixed with grab adhesive or pinned onto timber grounds. As with any glue work, clean, dry surfaces ensure a secure bond.
