What is the best cladding for a garden room?

Comparing Different Types of Cladding for Garden Rooms

When choosing cladding for your garden room, several factors such as durability, maintenance, aesthetics, and environmental impact play crucial roles. Here’s a quick comparison of various cladding options to help you make an informed decision.

Recently treated garden room with OSMO oil

Canadian Western Red Cedar

Pros:
  1. Natural Beauty: Distinctive rich hues of orange and red make a garden room look fabulous
  2. Durability: Resistant to decay and insects due to natural oils
  3. Sustainability: Renewable resources with a low carbon footprint.

Cons:
  1. Maintenance: Requires periodic staining or oiling
  2. Cost: Generally higher compared to some alternatives

Exterior of garden room, Grey wood

James Hardie Plank Cladding

Pros:
  1. Durability: Resistant to fire, moisture, and pests
  2. Low Maintenance: Minimal upkeep required
  3. Design Options: Available in 20+ colours and textures
  4. Longevity: Will outlast traditional wood cladding.

Cons:
  1. Installation: Labout intensive as the cladding must be cut and fitted on site as the panels would be too heavy if they were clad in the factory like timber cladding. The ends also need painting after being cut to protect them
  2. Environmental Impact: Higher than natural wood due to cement content.

Larch

Pros:
  1. Natural Strength: Tough and durable
  2. Aesthetic Appeal: Ages gracefully with a warm appearance
  3. Dimensional Stability: Resists warping better than something like Redwood
  4. Cost-Effective: Generally less expensive

Cons:
  1. Maintenance:  Requires periodic treatments because it will begin to fade and lose its colour if not treated/oiled every 12-18 months like any natural timber cladding. However, that is a look that some people like, see here for an example of a silvered larch and how nice it looks: Witness The Transformation of a Lifetime.
  2. Stability: Larch boards will shrink and expand through the year and may distort or move

Charred Larch (Shou Sugi Ban)

Pros:
  1. Unique Aesthetic: Modern, rustic appearance
  2. Enhanced Durability: Resistant to pests and fire
  3. Low Maintenance: The charred layer protects the wood.

Cons:
  1. Maintenance: Requires periodic treatments because it will begin to fade and lose its colour if not treated/oiled every 12-18 months like any natural timber cladding.
  2. Higher Initial Cost: It can be labour-intensive as any cuts or exposed ends require charring after cutting

  Garden room with Thermowood cladding. Thermowood is an ultra-heated timber that reduces the risk of raking, warping and shrinking ensuring a long-lasting and visually appealing finish.

Thermowood

Pros:
  1. Dimensional Stability: Thermowood is an ultra-heated timber that reduces the risk of raking, warping and shrinking
  2. Durability: Improved resistance to decay and insects
  3. Environmental Benefits: Heat-treated rather than chemically treated.
  4. Mid-range Cost: It is a lot more durable than Redwood and Larch and cheaper than Cedar and the composite options

Cons:
  1. Colour Fading: Will silver off over time if not treated with oil etc every 12-18 months
  2. Aesthetics: It's a very traditional look and requires lots of doors and windows to break up dark brown boards of cladding, which I think can be too much on large sections, but that is a personal choice. Like any natural timber, it will silver off over time if not oiled once every 12-18 months.

Redwood Shiplap Cladding like this from Travis Perkins

Redwood

Pros:
  1. Natural Beauty: Pale golden hues, perfect if you are going to paint your garden room
  2. Cost-effective: One of, if not the cheapest ways to clad your garden room
  3. Sustainability: Renewable resource with a moderate carbon footprint

Cons:
  1. Durability: As it is a soft wood it is prone to twisting, warping and splitting. Most garden room companies will only give a 5-year guarantee rather than a 10-year guarantee.

Answering Your Key Questions:

What is the cheapest way to clad a garden room?

Larch and Redwood are generally more cost-effective options compared to cedar or specialized cladding like Charred Larch or Millboard.
