Wood Building Materials: What You Need to Know
If you’re planning a conservatory, garden room or any home extension, wood is often the first material that comes to mind. It’s strong, versatile and can give your space a warm, natural look. But choosing the right timber and using it correctly can be a bit confusing. This guide breaks down the basics so you can make confident decisions.
Why Choose Wood for Your Project?
Wood scores high on three key fronts: strength, insulation and aesthetics. Modern engineered timber, like CLT (cross‑laminated timber), can support large spans that used to need steel or concrete. At the same time, wood’s natural insulation helps keep rooms cosy in winter and cool in summer. And let’s be honest – nothing beats the look of real timber exposed inside a sun‑filled conservatory.
Picking the Right Type of Timber
Not all wood is created equal. Softwoods such as pine and spruce are great for framing because they’re affordable and easy to work with. Hardwoods like oak or ash are better for visible surfaces where durability and grain are important. When you’re leaning towards a sustainable choice, look for FSC‑certified timber or locally sourced timber that reduces transport emissions.
Before you order, think about moisture. If your conservatory will be exposed to a lot of rain, choose timber treated for outdoor use. Treated softwood or naturally durable hardwoods like cedar can handle damp conditions without warping.
Another factor is fire rating. In the UK, building regs often require a certain fire performance level for structural timber. Check the supplier’s data sheet – most engineered timber products now meet the required standards.
Once you’ve selected the timber, pay attention to the joints. Modern timber frame systems use metal brackets, pre‑drilled plates or glued‑in connections that keep the structure tight and reduce the need for on‑site cutting. These systems speed up build time and minimise waste.
Installation is where many DIYers stumble. Make sure the timber is stored flat and covered to keep it dry before use. When fitting, leave a small gap at the base for ventilation – this prevents moisture buildup that can lead to rot.
Finishing touches matter. A good quality sealant or oil penetrates the grain, protects against UV rays, and highlights the natural colour. If you prefer paint, use a breathable, masonry‑grade paint so the wood can still “breathe.”
Wood isn’t just for the frame. You can use it for cladding, internal fittings, or decorative beams. Pairing timber with glass, which is a staple for conservatories, creates a light‑filled space that feels both modern and timeless.
Finally, remember maintenance. A quick annual check for loose fittings, signs of rot or paint wear will keep your wood structure looking great for years. Most issues are easy to fix with a sandpaper, fresh sealant and a bit of patience.
Wood offers a perfect blend of strength, beauty and sustainability for any home extension. By picking the right type, treating it properly and staying on top of maintenance, you’ll enjoy a sturdy, gorgeous space that adds value to your property.
