Balcony Tiles Lightweight Porcelain Paving Slab

The Compact 20 Porcelain Balcony Tile is a durable, 20 mm thick porcelain paving option crafted specifically for terraces, balconies, rooftop applications, and patios. The 300 mm by 300 mm size is highly appropriate for low-threshold doorways and small spaces, and its lighter weight per square metre enhances movement and eases edge cutting.

Characteristics & Advantages

Ultra-Thin Design: With a mere thickness of 20 mm, Compact 20 tiles allow for low edges or doorsills while maintaining high quality.
Lightweight but Sturdy: At approximately 44 kg/m², these tiles offer structural strength without adding excess weight to balcony or roof decks.
Resilient Porcelain Construction: Porcelain is stain-resistant, frost-proof, and virtually non-porous, making it low-maintenance and ideal for outdoor settings. UV stability ensures colours remain fresh over time.
Slip-Resistant R11 Finish: The surface offers enhanced traction in wet or exposed conditions, helping prevent slips and falls.
Flexible Installation: Suitable for laying on adjustable pedestals or bonded with polyurethane adhesive on flat roofs or balconies. It can also be installed over mortar beds using standard SBR bonding techniques on patios.
Compact Format Advantage: Smaller tile size reduces waste in bespoke layouts and allows easy handling—even in tight or awkward spaces.

Typical Applications

Ideal for residential or commercial balconies, rooftop terraces, low-threshold transitional areas, conservatories, and patios. The tile’s compact profile is perfect for applications where height clearance is limited, while offering a sophisticated porcelain finish.

Care & Maintenance

Routine sweeping and light rinsing with clean water are usually sufficient to keep the surface pristine. The dense, vitrified porcelain resists staining from dirt, debris, and household chemicals, reducing the need for cleaning agents. No sealing or resurfacing is required due to its non-porous nature.

Why Choose Compact 20 Porcelain Tiles?

With its slim profile, durable composition, premium R11 slip finish, and ease of handling, Compact 20 Porcelain is the ideal choice where a refined, low-height exterior surface is required. Whether installed over pedestals, bonded aggregates, or mortar bedding, it delivers elegant, resilient flooring with minimal fuss and maximum visual impact.

Features & Benefits

Elevated Base with Drainage: Rainwater can flow beneath the raised base, preventing buildup and moisture damage.
Dimensionally Stable: The tile, which has a thickness of about 22 mm, resists bending and cracking even under normal foot usage.
Minimal Maintenance: It only needs a fast rinse to maintain its nice appearance; no sealing is necessary.

After almost a year of deliberation and with limited options due to placement we decided on the grassflex tiles and 100% made the right choice. Great quality! Thank you

Absolutely amazing customer service from Fraser Brown! We had a delivery of outdoor tiles this morning, and our construction team was struggling to figure out how to use the levelling discs supplied. Fraser immediately stepped in and provided a direct WhatsApp number so the team could send videos and speak to him directly. The issue was resolved within five minutes. A huge thank you to Fraser for such responsive and hands-on support — truly appreciated!

A great experience with Castle Composites! We purchased the EPDM Rubber Tiles in ‘Sunburst’ for the kids’ play area section of our garden. Fraser was a wonderful help - from the first phone call enquiring about the product, showing us samples at the warehouse, liaising throughout the ordering and production process (and for helping with a later change to increase our order quantity within the same batch), to ensuring smooth delivery, Fraser’s customer service was fantastic and very much appreciated. The play area is now fully installed in our garden and we are delighted with the finished product. Thank you!

Excellent service from a great company with fantastic staff and a wonderful product. We have just used Castleflex tiles for our large patio and are very pleased with the end result. They look great and were easy to lay.
