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, 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: The brown aluminium decking option exudes warmth and elegance, making it an ideal choice for homeowners seeking to create a cosy and inviting outdoor space.
• Sand Aluminium Decking: The grey beige aluminium decking option strikes a perfect balance between modern sophistication and timeless elegance, making it a versatile choice for a wide range of design aesthetics.
• Beige Grey Aluminium Decking: The sand aluminium decking option exudes coastal charm and relaxation, making it an ideal choice for homeowners looking to create a tranquil and serene outdoor retreat.
• Almond Aluminium Decking: The almond aluminium decking option exudes warmth and versatility, making it a popular choice for homeowners seeking to create a timeless and inviting outdoor space.

Composite Decking

At Raaft®, we offer composite decking crafted from a blend of recycled wood fibres and plastic. Our composite decking offers the best of both worlds: the natural look and feel of wood combined with the durability and low maintenance of plastic. 

This innovative material is engineered to withstand the elements, making it an ideal choice for balconies subjected to varying weather conditions. Here's why it's a top contender:

• Durability: Resistant to rot, mould, and insect damage, composite decking can withstand the harshest of weather conditions, making it ideal for balconies exposed to the elements. Its resistance to moisture, fading, and staining ensures that it maintains its appearance and structural integrity for years to come.
• Low Maintenance: Say goodbye to sanding, staining, and sealing. Composite decking requires minimal upkeep, usually just a periodic cleaning with soap and water.
• UV Resistance: Composite decking is engineered to resist fading and colour changes caused by exposure to sunlight. UV-resistant coatings or pigments are often incorporated into the material during manufacturing, ensuring that the decking maintains its vibrant colour and appearance for years to come.

Porcelain Decking

For those seeking a blend of elegance and resilience, Raaft®’s porcelain decking emerges as a frontrunner. Made from high-quality porcelain, this decking option offers unparalleled strength and durability, making it an excellent choice for balconies exposed to heavy foot traffic and adverse weather conditions. Here’s why you should consider it:

• Strength: Porcelain decking boasts exceptional strength and durability, making it resistant to scratches, stains, and fading.
• Low Maintenance: Like its composite counterpart, porcelain decking requires minimal upkeep, typically just a routine cleaning to keep it looking pristine.
• Versatility: With an array of colours, patterns, and textures to choose from, porcelain decking allows for endless design possibilities, adding a touch of sophistication to any balcony space.

Porcelain Tiles

If you're looking for versatility and affordability, porcelain tiles may be the perfect fit for your balcony flooring needs. Porcelain tiles offer a budget-friendly alternative to full-size porcelain decking or composite options, without compromising on style or durability.

These tiles are available in a wide variety of sizes and finishes, allowing homeowners to create a customised look for their balcony that reflects their unique style and personality:

• Affordability: Porcelain tiles are often more budget-friendly compared to full-size porcelain decking or composite options.
• Easy Installation: With interlocking or adhesive-backed options available, porcelain tiles can be installed quickly and without the need for specialised tools.
• Variety: From sleek and modern to rustic and traditional, porcelain tiles come in a myriad of sizes and finishes, allowing you to create a customised look for your balcony.

What is the best decking for a balcony?

The best decking option for a balcony depends on factors such as durability, maintenance requirements, and aesthetic preferences. 

Porcelain, composite, and aluminium decking are often preferred for their durability and low maintenance, while porcelain tiles offer a budget-friendly alternative.

What is the thickness of balcony decking?

The thickness of balcony decking can vary depending on the material and manufacturer. Typically, composite decking boards range from 0.75 inches to 1.5 inches thick, while porcelain tiles may vary in thickness depending on the specific product.

Should a balcony have a drainage?

Yes, a balcony should have proper drainage to prevent water accumulation and potential damage to the structure. Without adequate drainage, rainwater or other sources of moisture can pool on the balcony surface, leading to issues such as:

• Water Damage: Standing water can seep into the balcony's structure, causing rot, decay, and deterioration of materials over time. This can compromise the structural integrity of the balcony and lead to costly repairs.
• Slip and Fall Hazards: Pooled water on the balcony surface can create slippery conditions, increasing the risk of slips and falls, particularly during wet weather or when the surface is wet.
• Mould and Mildew Growth: Moist conditions resulting from poor drainage can promote the growth of mould, mildew, and algae on the balcony surface. Besides being unsightly, these organisms can pose health risks to occupants and contribute to deterioration of materials.

What are the building regulations for a balcony?

Building regulations for balconies vary between the UK and the US, as they are governed by different codes and standards:

United Kingdom Balcony Building Regulations

In the UK, building regulations for balconies are primarily covered by the Building Regulations 2010, which are enforced by local authorities. Some of the key considerations include:

1. Structural Integrity: Balconies must be structurally sound and capable of supporting their intended loads, including people, furniture, and any other intended use.
2. Safety Barriers: Balconies must have appropriate safety barriers, such as railings or balustrades, to prevent falls. These barriers must meet specific height and strength requirements outlined in building regulations.
3. Materials: Building regulations may specify requirements for the materials used in balcony construction, particularly regarding their fire resistance and durability.
4. Drainage: Balconies must have adequate drainage to prevent water accumulation and potential damage to the structure.
   
   

In accordance with the latest British Standard for balcony and terrace design (BS8579), it's strongly advised to utilise non-combustible materials for decking in elevated outdoor spaces like balconies and roof terraces. 

Experts advocate for the removal and replacement of any existing combustible materials in balcony construction to ensure the safety and well-being of residents. This proactive approach is considered the most effective strategy for preventing the initiation of fires and limiting the spread of external fires.

United States Balcony Building Regulations

In the US, building regulations for balconies are governed by a combination of local building codes, as well as national standards such as the International Building Code (IBC) and the International Residential Code (IRC). Some of the key considerations include:

1. Structural Requirements: Balconies must be designed and constructed to meet structural requirements outlined in local building codes, ensuring they can safely support their intended loads.
2. Guardrail Requirements: Balconies must have guardrails or balustrades that meet specific height and strength requirements to prevent falls. These requirements may vary depending on the height of the balcony above the ground.
3. Materials and Construction: Building codes may specify requirements for the materials used in balcony construction, including their fire resistance, durability, and resistance to weathering.
4. Access and Egress: Balconies must provide safe access and egress, particularly in emergency situations. This may include requirements for stairs, ramps, or other means of access.
5. Inspections: Balconies may be subject to periodic inspections to ensure compliance with building codes and regulations, particularly in multifamily residential buildings or commercial properties.
