Wood nails; The perfect substitute for steel.
Although I don't think I need to remind you, the nails they are and have been one of the greatest utilities that we can find; since the invention of steel nail or of wire with its massive and really cheap production was built the development of the industrial era, buildings, houses, furniture … etc.
They have had a thousand uses throughout their history, but in the era of creative recycling and sustainable development they are the negative part that we do not see, it actually makes recycling overwhelmingly difficult if we talk about the wood sector.
In the market we can find different types of nails; larger, smaller, headless, more resistant or less, with different geometric shapes, and a multitude of materials such as plastic, although undoubtedly the metal nails and the staples They are the kings of DIY, well, until now!
An Austrian company (Lignoloc - Beck Fasteners) has invented something that I thought was not possible or at least not feasible; the wood nails. Obviously they won't be able to be struck with our newly purchased steel hammer, but they strike perfectly with a new special pneumatic gun system. So take note!… Because we can build a 100% recyclable wooden house based on nails made of wood.
First we want to leave a video that possibly more than one carpenter will be surprised:
Wood Nail Features
These types of wood nails they provide us with unique characteristics. The nail is made of beech, compressed with a special resin so that they are as hard as aluminum or typical wood staples. According to the manufacturer, they come in lengths of up to 65 millimeters.
They have high retention thanks to the lignin solder (It is like weld the wood). Thanks to the amount of heat generated by friction when it is nailed (pneumatically injected), the lignin from the nail tip welds with the surrounding wood to form an almost perfect substance-to-substance bond. The truth is that lignin welding is quite curious, so we leave the following video to see it.
It allows the fibers of the wood to intertwine, forming a dense matrix of intercellular material that later, when allowed to cool, would constitute a weld bead.
Advantages of using wood nails
Although it is evident that each material has its advantages, we want to shed some light on what advantages it can bring us using wooden nails in a construction or our daily work. First we want to leave a video that possibly more than one carpenter will be surprised:
- Quick and easy work with pneumatic nailers.
- Water absorption is almost nil, so there is no expansion.
- High clamping force thanks to lignin welding, due to pneumatic injection.
- High resistant to fungal infestation.
- No grooves or bleeding in the wood.
- More environmentally friendly with reference to other metal fasteners. Not counting recycling times, waste … etc.
- Installed significantly faster than typical wooden dowels.
- No pre-drilling is required.
- You do not need any use of glues - wood adhesives.
- Produced from native and certified beech wood.
- Better fire protection on wood frame than steel or metal fasteners.
- No thermal bridges, thus improving insulation values.
- Tensile strength, similar to aluminum nails (~ 250 N / mm²)
- Less wear on tools when subsequently cutting the different nailed pieces of wood.
Really the possibilities of using this type of nails in different fields such as interior cladding or wooden facades, in floors, saunas, any roof rehabilitation work or the works themselves and in the field of construction, ship building, coffins … etc.
They are infinite!…. No more saws or polishers breaking when touching the steel of a nail, 100% reuse, goodbye to thermal bridges or bleeding of wood. Anyway, it seems to us an exceptional idea.
