Choosing the right decking material for your outdoor space is crucial, especially if the area will be exposed to prolonged periods of direct sunlight. The hot rays combined with the UK’s variable climate can quickly damage deck boards that aren’t properly suited for the conditions. Finding a material with excellent UV resistance, durability, and low maintenance requirements ensures your deck will remain beautiful for years to come.
To guarantee the best choice for your deck, consulting with Finetune Fencing Farnborough experts is advisable. These professionals specialize in providing guidance on selecting decking materials that offer optimal UV resistance and durability, ensuring your deck withstands the challenges of the UK climate while maintaining its aesthetic appeal.
Types of Deck Materials
Wood Decking
Wood has a timeless, natural beauty and richness that can significantly enhance your outdoor space. There is an abundance of tree species to choose from, each with their own unique grain patterns, textures, and natural hues.
Pros:
- Warm, natural aesthetic
- Huge variety of wood species and appearances
Cons:
- Prone to UV damage, fading, warping, and rotting
- Requires extensive maintenance like annual sealing/staining
Composite Decking
Composite deck boards blend recycled wood fibers, plastic polymers, and other materials to create a durable, weather-resistant deck board. The composition varies slightly between brands.
Pros:
- Extremely low maintenance requirements
- High resistance to moisture, rot, mold, and UV damage
Cons:
- Higher upfront installation costs
- Limited color/style options
PVC Decking
PVC deck boards are made entirely from a tough, resilient plastic material that stands up well to outdoor elements. They resemble wood grains but require less maintenance.
Pros:
- Superior moisture, mold, and UV resistance
- Minimal required maintenance
Cons:
- Prone to scratches
- Lacks natural wood visual appeal for some
When evaluating how prone a material is to sunlight damage, assessing its UV resistance and color fading tendencies is crucial.
UV Resistance and Color Fading
Over time, exposure to harsh UV rays can cause decking material to become dried out, brittle, cracked, warped, or discolored. When deck boards lose their integrity from sun damage, it causes safety hazards and often necessitates full deck replacement. Checking a material’s inherent abilities to withstand intense sunlight without degrading is one of the most important considerations.
Wood Decking
Of the main three decking materials, wood is the most intrinsically vulnerable to sun damage. The natural wood fibers break down over time with intense UV exposure. Sealing and staining provide a protective barrier to shield it, but this requires removing and reapplying the finish every 1-2 years. Even with ideal maintenance, the color still naturally lightens to a weathered gray over the years.
Composite & PVC Decking
Both composite and PVC decking retain their color extremely well even with constant sun exposure. The polymer materials are engineered to encapsulate and protect the color pigments from fading. Both can last upwards of 25+ years before needing replacement (much longer than typical wood decks).
When installed in a particularly sunny location, PVC or composite boards are vastly superior decking options if maintaining a consistent appearance over decades is a priority. But another crucial consideration is how the UK’s unique climate impacts real-world performance…
Climate Considerations in the UK
The United Kingdom brings a distinctive set of weather conditions that impact outdoor decking: cool temperatures, abundant rainfall, humidity, and rapid fluctuations between sun and stormy skies. Selecting a deck board able to withstand the temperamental UK elements is key.
Moisture Resistance
Wet weather is nearly a constant. Deluges of rain combined with the ocean air creates exceptionally humid, damp conditions. Decking material without proper moisture barriers will be prone to issues like:
- Swelling
- Cupping
- Splintering
- Rotting
- Mold growth
Wood decking is particularly vulnerable unless meticulously sealed and cared for annually. Even then it still absorbs ambient moisture.
Composite and PVC options have exceptional resistance to water degradation issues. Their polymer construction resists swelling and retains structural integrity even after decades of rain exposure.
Temperature Fluctuations
The UK weather can shift rapidly from balmy sunshine to frigid sleet storms. Decking material needs stable temperature tolerances to avoid expansion/contraction damage like cracks or warping.
Wood expands and contracts the most with temperature changes. Composites have some movement but are more thermally stable. PVC deck boards retain original dimensions the best regardless of conditions.
When assessing decking for the UK, be sure to confirm moisture tolerance and stability across climate shifts before purchasing. Materials unable to withstand the elements will require frequent replacement or extensive repairs.
Maintenance Requirements
Another pivotal factor is the necessary upkeep the decking will need on a monthly/yearly basis to preserve visual appeal and functionality. High maintenance materials become labor intensive and expensive over their lifespan.
Wood Deck Maintenance
Without diligent care, wood decks deteriorate rapidly in sunny, wet environments. At minimum, they require:
- Thorough cleaning twice per year
- Sanding every 2-3 years
- Sealing or staining every 1-2 years
Yearly inspections check for:
- Splinters
- Warping boards
- Rot
- Insect infestations
Neglected wood decks can become unsafe and often need full replacement in 5-10 years.
Composite Deck Maintenance
One of the main appeals of composite decks is the minimal upkeep required. Suggested maintenance includes:
- Quick hose-down /mopping several times per year
- Inspecting periodically for mold, mildew, or debris between boards
Deep-cleaning with a composite deck cleaner every few years maximizes longevity.
PVC Deck Maintenance
Similar to composite, PVC decking needs little ongoing maintenance:
- Occasional soap and water cleaning
- Inspecting for scratches/damage
Its slick surface deters buildup of pollen/debris between boards. But also take care not to scratch the surface when moving furniture across it.
For low maintenance and reliable performance in harsh UK sun and rain, PVC or composite significantly outlast wood options.
Frequently Asked Questions
What is the most UV-resistant decking material?
PVC deck boards have the highest inherent UV resistance and experience the least color fading or damage issues over decades of sun exposure.
How often should I inspect my deck for sun damage?
Wood decks should be checked for splinters, warping, and rot every spring and fall. PVC and composite decks need only occasional inspection for surface scratches or debris buildup; full replacement may never be necessary.
Are there any eco-friendly deck options?
While wood is renewable, certain composite brands use recycled plastic, reclaimed wood fibers, and sustainable harvesting initiatives to produce eco-friendly boards. Check manufacturers for specifics.
Can I paint or stain PVC decking?
PVC decking cannot be painted or stained. The factory polymer color runs throughout the entirety of the boards. Painting it voids the warranty.
Which is the best deck material for a sunny UK garden?
For optimal durability across decades of sun, rain, and ever-changing weather, PVC or composite boards make the best decking materials for consistent performance in UK conditions with minimal maintenance needs.
