Balcony Decking Systems 101: Choosing the Right Foundation for Your Outdoor Space

When it comes to installing decking on a balcony or high-rise building, there are numerous factors to consider before getting started. The material you pick is critical for health and safety as well as structural integrity, and with many choices available, it can be tough to know where to begin.

Whether you're renovating an existing balcony area or planning to add one to your home, selecting the proper decking material is key. With so many different types of deck boards to pick from, health standards must be a top priority when selecting one for your project.

In this guide, we'll explore the decking options from Raaft® and address common questions to help you make an informed decision for your balcony project.

Balcony Decking System Materials

Balcony decking system materials play a crucial role in enhancing both the aesthetics and safety of outdoor spaces. Whether it's a high-rise apartment balcony or a cosy terrace, choosing the right decking material is essential for durability and longevity.

Moreover, adhering to building regulations, such as the preference for non-combustible materials, ensures the safety and well-being of residents. Ultimately, selecting the appropriate decking material ensures the creation of a functional and visually appealing outdoor retreat for relaxation and enjoyment.

Aluminium Decking

At Raaft®, we offer lightweight yet durable aluminium decking. Constructed from high-quality aluminium alloy, this decking option is engineered to withstand the elements, making it ideal for outdoor applications.

Durability:
Resistant to rust, corrosion, and rot, aluminium decking is built to last, even in the most challenging outdoor environments.

Low Maintenance:
With minimal upkeep required, aluminium decking is easy to clean and maintain, making it perfect for busy homeowners.

Heat Resistance:
Unlike some decking materials that can become uncomfortably hot in the sun, aluminium decking stays cool, ensuring comfort underfoot during the hottest summer days.

Raaft®’s aluminium decking is currently available in four premium finishes:

  • Brown Aluminium Decking: Exudes warmth and elegance, ideal for creating a cosy and inviting outdoor space.
  • Sand Aluminium Decking: Strikes a balance between modern sophistication and timeless elegance, suitable for a wide range of design aesthetics.
  • Beige Grey Aluminium Decking: Offers coastal charm and relaxation, perfect for creating a tranquil outdoor retreat.
  • Almond Aluminium Decking: Delivers warmth and versatility, making it a popular choice for timeless outdoor spaces.

Composite Decking

At Raaft®, we offer composite decking crafted from a blend of recycled wood fibres and plastic. This material combines the natural look and feel of wood with the durability and low maintenance of plastic.

Engineered to withstand the elements, composite decking is ideal for balconies exposed to varying weather conditions.

Durability:
Resistant to rot, mould, and insect damage, composite decking maintains its appearance and structural integrity for years.

Low Maintenance:
No sanding, staining, or sealing required — just occasional cleaning with soap and water.

UV Resistance:
Designed to resist fading and colour changes caused by sunlight, keeping the decking vibrant over time.

Porcelain Decking

For those seeking a blend of elegance and resilience, Raaft®’s porcelain decking is an excellent choice. Made from high-quality porcelain, it offers exceptional strength and durability, making it ideal for balconies exposed to heavy foot traffic and harsh weather.

Strength:
Highly resistant to scratches, stains, and fading.

Low Maintenance:
Requires only routine cleaning to maintain its appearance.

Versatility:
Available in a wide range of colours, patterns, and textures for flexible design options.

Porcelain Tiles

Porcelain tiles provide a versatile and budget-friendly alternative to full-size porcelain decking or composite options without compromising on style or durability.

Available in a wide variety of sizes and finishes, porcelain tiles allow for a customised balcony design.

Affordability:
More cost-effective than full-size decking options.

Easy Installation:
Interlocking or adhesive-backed options enable quick installation without specialised tools.

Variety:
Styles range from sleek and modern to rustic and traditional.

What Is the Best Decking for a Balcony?

The best decking option depends on durability, maintenance requirements, and aesthetic preferences.

Porcelain, composite, and aluminium decking are commonly preferred for their durability and low maintenance, while porcelain tiles offer a more affordable alternative.

What Is the Thickness of Balcony Decking?

Decking thickness varies by material and manufacturer. Composite decking boards typically range from 0.75 to 1.5 inches thick, while porcelain tiles vary depending on the product.

Should a Balcony Have Drainage?

Yes, proper drainage is essential to prevent water accumulation and structural damage.

Without adequate drainage, balconies may suffer from:

  • Water Damage: Moisture infiltration can cause rot and material deterioration.
  • Slip and Fall Hazards: Standing water increases safety risks.
  • Mould and Mildew Growth: Persistent moisture encourages unhealthy growth.

What Are the Building Regulations for a Balcony?

Building regulations vary between the UK and the US.

United Kingdom Balcony Building Regulations

UK balconies are governed by the Building Regulations 2010. Key considerations include:

  1. Structural integrity to support people, furniture, and intended loads
  2. Safety barriers such as compliant railings or balustrades
  3. Material requirements, particularly for fire resistance and durability
  4. Adequate drainage to prevent water accumulation

In line with British Standard BS8579, non-combustible materials are strongly recommended for balconies and roof terraces. Replacing existing combustible materials is widely considered the most effective approach to reducing fire risk.

United States Balcony Building Regulations

In the US, balconies are regulated by local codes and national standards such as the IBC and IRC. Requirements typically include:

  1. Structural load compliance
  2. Guardrail height and strength
  3. Material durability and fire resistance
  4. Safe access and egress
  5. Periodic inspections, particularly for multi-residential buildings
