Understanding Shiplap and Loglap Cladding
What is Shiplap Cladding?

Shiplap cladding is characterised by its long, horizontal boards that overlap each other, forming a smooth and weatherproof surface. Known for its clean lines and simplicity, it offers a classic look that works well with modern and traditional architectures. An option like the 16x125 T&G Tanalised Treated Shiplap provides superior durability due to its pressure-treated properties, making it a popular choice for resisting the UK weather.
What is Loglap Cladding?
Loglap cladding brings a more rustic charm, with its half-log design mimicry providing the aesthetic of a log cabin. The boards overlap similarly to shiplap but create a more pronounced shadow line, offering texture and depth to your façade. It suits projects aiming for a natural, outdoorsy appearance. However, maintenance should be considered, as the rounded profile can make cleaning slightly more complex than shiplap.
Key Considerations for Choosing Between Shiplap and Loglap
Appearance
-
Shiplap: Offers a sleek, seamless look ideal for modern styles.
-
Loglap: Provides a textured, rustic appearance, excellent for a countryside or natural theme.
Installation & Maintenance
-
Shiplap: Known for its easy installation process due to the simple overlapping design. It's also relatively straightforward to maintain.
-
Loglap: Installation can be more intricate due to its shape, and it may require slightly more labour in maintenance due to debris collection in the rounded profiles.
Durability and Weather Resistance
Both claddings offer satisfactory protection against the elements; however, depending on the treatment level of the wood, the longevity and maintenance may vary. It's crucial to consider treated vs untreated timber. Treated timber, like the 16x125 T&G Tanalised Treated Shiplap, offers greater resistance to rot and decay.
Budget
-
Shiplap: Generally, more cost-effective and favoured for budget-conscious projects.
-
Loglap: Typically a bit pricier due to the intricate profile but offers unique aesthetic advantages.
Beyond Cladding: Selecting Compatible Materials
OSB vs Plywood

Both OSB vs plywood are excellent for structural uses. OSB is often used in wall sheathing due to its affordability and strength, whereas plywood offers superior surface smoothness. For projects involving cladding, consider the 18mm OSB3 Board.
Roof Felt vs Roof Shingles

Roofing choices affect both appearance and longevity. For a traditional, cost-effective option, consider the Polyester Shed Roofing Felt - Charcoal Mineral. Alternatively, for a more robust, visually appealing finish, the Hexagonal Reinforced Fibreglass Roofing Shingles stand out with excellent durability.
Timber Project Planning
When planning your project, size and quantity decisions are critical:
Choosing Timber Framing Sizes
The dimension of framing should align with the structural demands and aesthetic desires of your project. For garden buildings and similar structures, ensure compatibility with the chosen cladding type to maintain structural integrity.
Choosing Decking Board Quantities
Calculating the needed decking boards involves assessing your space, considering board sizes, and accounting for potential waste. This helps avoid underordering or wastage, optimising budget and resources.
Choosing Plywood Thickness
When selecting plywood, particularly for base layers beneath cladding or roofing, its thickness plays a role in stability and support. Ensure your choice meets the load requirements for your specific project.
Decking Kits vs Individual Materials
Opting for a decking kit can streamline construction and ensure material compatibility. Yet, selecting individual materials might allow customisation to exact dimensions and preferences if your requirements are unique.
Making the Final Decision
Before finalising your order, ask yourself these questions:
- Does the cladding style fit with my overall design vision?
- What is my budget for both materials and installation?
- Am I prepared for the level of maintenance each cladding requires?
- Have I considered how the chosen cladding will interact with other materials (e.g., roofing, framing)?
By addressing these considerations, you'll minimise potential pitfalls.
Balanced Recommendation
Choosing between shiplap vs loglap cladding boils down to personal preference and project specifications. If your primary focus is a smooth finish and simplicity, shiplap is ideal. However, if rustic charm and a prominent aesthetic are your goals, loglap is worth the investment.

FAQs
What is shiplap cladding?
Shiplap cladding is a method of joining wooden boards with a rabbet or groove cut into their edges, creating a tight-fitting structure. This technique not only enhances the aesthetic appeal of buildings but also provides a layer of protection against weather elements.
What is loglap cladding?
Loglap cladding consists of overlapping timber boards that mimic the look of logs or large timber sections. This style is often favoured for its rustic charm and offers a traditional appearance suited to various architectural designs.
Which type of cladding is more cost-effective?
Generally, shiplap cladding tends to be more affordable than loglap cladding. The cost difference can be attributed to the materials used and the complexity of installation. However, prices can vary based on type, quality, and supplier.
Is shiplap or loglap easier to install?
Shiplap cladding is often considered easier to install due to its interlocking design, allowing for quicker assembly. Loglap may require more effort in achieving proper alignment and securing its rounded edges.
How do shiplap and loglap compare in terms of insulation?
Both shiplap and loglap cladding can provide effective insulation, but the thickness and treatment of the timber can influence performance. Shiplap’s joints can offer a tighter seal, potentially enhancing thermal efficiency.
What maintenance do shiplap and loglap cladding require?
Both types of cladding need periodic maintenance to prolong their lifespan. Regular cleaning, sealing, and the application of wood preservative can help protect against moisture, rot, and pests.
Which cladding style suits modern versus traditional homes?
Shiplap cladding complements modern architectural styles with its clean lines and versatility, while loglap cladding works beautifully with traditional or rustic designs, enhancing the overall warmth and character of older homes.
Can I paint or stain shiplap and loglap?
Yes, both shiplap and loglap can be painted or stained, allowing homeowners to achieve their desired look and protect the wood. It’s essential to choose suitable finishes that will adhere well and offer long-lasting protection.
What are the aesthetic differences between shiplap and loglap?
Shiplap has a more uniform, rectangular appearance with crisp edges that suit contemporary designs, while loglap offers a more textured, rounded look that evokes a natural, rustic feel, making it ideal for those seeking a traditional aesthetic.
