Choosing Between Log Lap and Shiplap Cladding

Cladding is a pivotal component in the world of timber construction, offering both aesthetic appeal and functional benefits for various structures. If you're contemplating adding or rejuvenating cladding in your next DIY project, you’ve likely come across log lap and shiplap cladding as popular options. This blog post explores both cladding types, helping you make an informed decision for your next garden improvements or timber building materials project.

Understanding Timber Claddings

Timber claddings are essential not only for their protective capacity but also for their contribution to the overall charm of wooden structures. The choice of cladding can impact the durability, sustainability, and aesthetic appeal of your structure. Whether it’s for protecting your shed, enhancing your decking area, or boosting your garden structures, understanding your options is vital.

Log Lap Cladding – A Traditional Favourite

Log lap cladding is cherished for its rustic appearance. It mimics the look of traditional log cabins, providing a distinct and cosy charm that’s hard to beat.

Key Features

  • Aesthetic Appeal: The rounded profile of log lap provides a traditional, rustic veneer, often chosen to emulate a more natural setting.
  • Durability: Ideal for outdoor settings, log lap cladding is famed for its robustness and protection against harsh weather.
  • Sustainability: Often sourced from sustainable forests, log lap supports eco-friendly building practices.

The installation of log lap is straightforward but requires precision:

  • Preparation: Ensure your base is level and strong, using tanalised timber framing like the 4x2 or 3x2 tanalised framing.
  • Nailing or Screwing: Use galvanised nails or screws to secure the cladding effectively.
  • Finishing: For aesthetic and protective purposes, consider treating your cladding with wood stains or paints suitable for outdoor use.

Shiplap Cladding – The Modern Marvel

Shiplap cladding, on the other hand, is synonymous with modern efficiency and sleek designs. Its smooth appearance suits contemporary builds perfectly.

Key Features

  • Moisture Resistance: The overlapping design of shiplap makes it highly effective against water ingress, maintaining the integrity of the structure it protects.
  • Easy to Paint: Shiplap offers a polished finish that’s easy to cover with paint, allowing you to customise your structure’s appearance.
  • Optimal Insulation: Helps in providing added insulation to exteriors, which can be crucial for energy conservation.

  • Overlapping Technique: Ensure each board overlaps precisely for optimal moisture resistance.
  • Sealing: Apply a waterproof sealant to prevent moisture penetration.

Considerations for Sustainable Woodworking

When considering either type of cladding, it's essential to factor in sustainability. Both log lap and shiplap can be sourced from sustainable timber resources, aligning with eco-friendly building standards.

  • Certifications: Look for FSC or PEFC certifications to ensure the wood is sustainably sourced.
  • Recycled Options: Some suppliers may offer cladding made from recycled materials, further augmenting eco-conscious efforts.

Adding Value with Timber Building Materials

Beyond cladding, incorporating timber building materials such as OSB boards, Plywood, and roof shingles can elevate the functionality and aesthetic of your project. Whether you’re working on a robust garden shed or a tranquil decking area, these materials are beneficial allies.

Enhancing the Roof with Roof Felt and Roof Tiles

For those looking to further safeguard their structures, employing roof felt or roof tiles is prudent. They add an additional layer of protection from the elements, ensuring longevity.

Your choice between log lap and shiplap cladding should consider both aesthetics and functionality:

  • If you're drawn to a rustic, cabin-like appearance, log lap is the way to go.
  • For a clean, modern look with excellent water-resistant properties, shiplap shines through.

Remember, both are excellent options that provide aesthetic and protective benefits worthy of your investment.
