It’s often thought that bamboo flooring is just another type of hardwood. Yet, its differences and benefits are quite something. In this post, we discover what makes bamboo unique and why it’s such an appealing choice of floor for the home or commercial environment. The guide covers everything you need to know about the flooring including where it’s from, the types available, how it’s finished and how you can incorporate the style into a traditional or contemporary space.
What is bamboo?
Let’s start with a fact that might be surprising: bamboo isn’t a wood but a grass. And it’s not your typical type of grass either. The plant is super strong and very quick-growing. In fact, it reaches its peak height of 20 metres within just a couple of months, growing at amazing speeds of up to 1 metre a day during its growth season. The stem is fully matured and ready for harvesting within just 4-5 years making bamboo the fastest growing plant on our planet and one of the most renewable resources available.
But you might be thinking how can a grass possibly be strong enough for flooring? Although you’d normally associate grass with the soft and flexible green plant that spreads over our garden lawns and fields, bamboo is a much different material. Once fully matured, the plant acquires characteristics that are very similar to hardwood, becoming a highly durable material that offers even better stability than many wood floors. Bamboo’s intrinsic hardness means it can be used to make some of the strongest materials in the world including bridges, houses, furniture and of course, bamboo flooring.
Basically, bamboo combines the merits of hardwood with an astounding growing capacity, making it an all-round awesome material.
Where does bamboo flooring come from?
There are more than 1500 species of bamboo native to 5 continents of the world: Africa, Asia, South America, North America and Australia. The plant also grows in Europe after being introduced in the 1800s, leaving Antarctica as the only continent where the plant isn’t found.
Although bamboo populations are in abundance, only one species is truly suitable for flooring. This grows mainly in China and is called the ‘Phyllostachys Pubescens’ or is known as the Moso bamboo. It’s from these highly robust and accessible forests that Woodpecker bamboo flooring is sourced.
What about the pandas? Is bamboo flooring a threat to them?
It’s true that a panda’s diet consists almost entirely of bamboo. In fact, the plant is such a poor source of nutrition that the animal often needs to eat up to 20kg of bamboo every day, which can take up to 16 hours! Yet the Moso species of bamboo that we harvest for flooring doesn’t grow in the animal’s habitat and even has inaccessible leaves. Pandas live in the Central mountain ranges of China where they feed on smaller bamboo species with leaf growth on the lower areas of their stems. This means Woodpecker bamboo flooring poses no threat to the panda!
How is bamboo flooring made?
As bamboo is a hollow plant, the manufacturing process for flooring is significantly different to that typical of hardwoods. After the bamboo has been harvested, the green outer-hull is removed from each of the canes to access their inner stalks. This part of the plant is then cut into long strips known as fillets and these are milled on their outer sides to remove their natural curvature and create more versatile flat strips. The strips are then dried and boiled to remove moisture, natural sugars and starches.
There are two main benefits of the boiling process:
- The bamboo is less desirable to certain insects that can tend to infest the plant. This is a key benefit to homes in tropical locations that are prone to termite infestations.
- The bamboo is less likely to suffer expansion and contraction with humidity changes.
After the bamboo strips have been prepared, they can then be manufactured into one of two types of bamboo flooring. The waste fibres produced from milling the edges of the fillets doesn’t go to waste either but is used to create another different type of bamboo flooring…
What are the types of bamboo flooring?
There are three different types of bamboo flooring: laminated vertical, laminated horizontal or strand-woven. Each of these are produced differently, have a different look and varying benefits.
Vertically Laminated Bamboo Flooring
As shown in the diagram above, vertically laminated bamboo flooring consists of strips of bamboo which are bonded together at a vertical angle. The result is a narrow grain pattern which shows clear definition between each strip in the board but doesn’t display the natural nodes and patterns in the bamboo.
The overall appearance is uniform and consistent which usually makes this type of bamboo flooring a preference for modern interiors or vibrant themes that fit with an understated base.
Horizontally Laminated Bamboo Flooring
Horizontally laminated bamboo flooring is produced from strips of bamboo bonded together at a horizontal angle, revealing a wider grain pattern which shows the natural knuckles and growth rings in the bamboo more clearly than the vertical alternative. This type of bamboo is often described as having a more natural appearance as it shows the unique intricacies and shape of the bamboo cane.
To create planks that are thick enough to be used for flooring, three layers of the horizontally bonded flat strips are glued together, as shown in the diagram above.
Aside from appearance, the vertical and horizontal types of bamboo flooring are very alike in practicality. Each type has a similar hardness to oak flooring and is suitable for laying over underfloor heating. Both types are regarded as traditional simply because they represent the first ways in which bamboo flooring was made.
Woodpecker horizontal and vertical bamboo floors are finished with 5 coats of UV Lacquer for protection, durability and style. Discover them in our Oxwich collection.
Strand Woven Bamboo
Strand woven is considered a more contemporary type of bamboo flooring as it has evolved from the original manufacturing techniques to accommodate extra hardness and durability. This type of flooring is produced by coating raw bamboo fibres (the ‘waste’ fibres from milling bamboo fillets) in resins and then compressing these strips together under extreme heat and pressure. The compressed material is then transformed into flooring planks which are twice as hard as vertical or laminate constructions and one of the hardest types of natural flooring available today.
Strand woven bamboo flooring also looks different. The weaved fibres are evident within the planks, capturing a natural yet unusual look across the floor. However, this type of bamboo flooring doesn’t retain any of the natural features of the cane, such as the knuckles and growth rings. It also looks similar to hardwood with the weaved fibres alike to wood grains.
Strand woven bamboo is also suitable for underfloor heating. Discover this type in the Woodpecker Oxwich collection.
Is bamboo flooring available in different colours?
The natural colour of bamboo is a light, sunny golden shade which makes an easy complement for many interior styles. Yet, everybody has their own tastes and bamboo flooring is available in other colours to suit these. Alternative shades can be achieved by treating the flooring in a process called carbonisation or by staining the surface.
The carbonisation process involves steaming the bamboo under extreme temperatures. This causes the sugars inside the porous plant to caramelise and transform in colour to a coffee-like brown hue. The main advantage of carbonised bamboo is that the tone runs right through the entire product. This means that a small scratch or dent wouldn’t reveal a different colour deeper in the floor.
Something to bear in mind is that bamboo does lose some of its strength following the carbonisation process meaning it doesn’t rate as hard as its natural strand-woven alternative. Yet, tough finishes provide protection to the surface of the floor and ensure that carbonised bamboo is still more than practical for laying in all the typical areas of the home.
Bamboo flooring can also be stained to various colour shades, accommodating the stain on its surface just like a hardwood does. The bamboo’s natural features and textures remain visible from beneath the stain, capturing an appealing effect which can create real statement in the home.
How is Bamboo Flooring Fitted?
Just like hardwood, bamboo flooring can be fitted in a number of different ways and the fitting system all depends on the type of bamboo floor and the supplier! Woodpecker laminated and horizontal bamboo floors include a traditional tongue and groove joint – a system commonly used with solid wood floors and the most recognised fitting system to the trade.
The tongue and groove system enables each plank to be neatly locked together and glued either between the joints or stuck directly to the subfloor. Tongue and groove planks can also be secret nailed to a timber subfloor or joists.
Woodpecker Oxwich Strand Bamboo is fitted differently with a glueless clic system that enables the planks to be locked together and floated over an underlay without the need for any adhesive. This allows for a quicker installation which is also slightly less messy and allows to the floor to be used immediately after installation.
How is bamboo flooring finished?
Commonly used wood finishes are applied to bamboo flooring for extra protection and durability. A strong Lacquer finish coats Woodpecker bamboo flooring, adding a dull sheen to the surface which doesn’t take away from the floor’s natural look. Every floor in our Oxwich collection receives 5 coats of the lacquer, providing excellent resilience against scratches, spills and stains.
What are the benefits of bamboo flooring?
The most obvious eco-friendly benefit of bamboo flooring is its availability. The bamboo plant naturally regenerates within a period of 5 years, allowing up to 25% of a forest to be harvested every year without decreasing the size of a plantation. One of the main reasons bamboo is so available is because it grows well in soil of poor quality and is self-propagating: able to flourish well without chemical treatments. It also spreads easily, needing little water or care and is able to persevere in some of the most extreme climatic conditions.
What’s more, the bamboo plant isn’t actually killed during harvesting. One bamboo plant consists of several poles and new shoots grow from the mother plant every year. Harvesting the poles also helps to improve the yield of the forest: as the older stems are removed, the younger bamboo is given more space for growth.
Bamboo is the fastest growing plant on our earth and one of the most sustainable resources the planet knows of today.
Sourced from Well-Managed Forests
The Moso bamboo forests which are harvested for Woodpecker bamboo flooring are stringently looked after to ensure the sustainability of the bamboo. In fact, the bamboo reserves in China are so significant and well managed that the forests are growing at a healthy rate of 5% annually. Plus, we only source from Forest Stewardship Certified (FSC) plantations. Their goal is ours: to ensure that forests can meet the needs of the present generation without compromising those of the future. By making it our responsibility to source our bamboo with care, we can be can be confident that we’re bringing you a beautifully and ethically sourced floor to enjoy in your home.
Little Waste Involved in Manufacturing
The process of creating flooring from bamboo is one that involves minimal waste. All of the cane’s stalk can be manufactured with the milled strips producing vertical or horizontal bamboo and the waste fibres processed into the strand-woven type.
Durability is often an overlooked factor of sustainability. The longer a floor lasts then the lower the environmental impact in terms of replacement. All types of bamboo flooring offer excellent hardness which can provide a sturdy floor for more than a lifetime. In fact, the plant has an intrinsically strong molecular structure with a tensile strength that’s actually stronger than steel!
Bamboo flooring has a distinct look which is much different to that found in hardwoods. Many people prefer this more unusual appearance in their home and enjoy the idea that their flooring is sourced from exotic forests. As bamboo is available in its natural or carbonised colours, together with stained shades, there’s also a lot of flexibility when it comes to choosing the flooring, with a shade to suit any interior style.
Easy to Clean
While the finish of bamboo flooring adds protection and durability, it also provides a surface that’s easy to maintain. The flooring can be cleaned just like a hardwood with regular sweeping or vacuuming and the occasional damp mop using a suitable cleaning solution.
Bamboo naturally contains an anti-bacterial agent known as Bamboo Kun. This eliminates up to 70% of bacteria which attempts to grow on the plant making for floor that naturally helps to ward off germs in the home.
Suitable for Underfloor Heating
All types of bamboo flooring are suitable for laying over underfloor heating and have a tog rating well within the recommended limit which allows for good heat transfer.
Suitable for Almost Anywhere in the Home
Bamboo flooring can add edgy style to almost any room in the home including living rooms, hallways, kitchens, bedrooms and studies. The only room in which we don’t recommend laying bamboo is the bathroom. This is because, just like hardwood, bamboo is susceptible to expansion and shrinking with sudden changes in humidity. The regular fluctuations in temperature and moisture that are typical of the bathroom are a threat to destabilising the flooring and could result in cupping or gapping between planks.
We’ll finish off with some amazing facts about Bamboo:
- Thomas Edison’s first lightbulb used a bamboo filament.
- Bamboo survived the atomic bomb blast in Hiroshima in 1945 and was the first plant to re-green following the eruption.
