−	Nail laminated timber (NLT or also called nail-lam) uses standard dimension timbers (normally 2" x 4", 6", 8" or 10"). The individual members are laid on edge and nailed to the next timbers with a relatively high number of long, strong galvanised nails, which gives strength and weight enough to qualify as a massive wood panel product. In German it may be referred to as nail brettstaple translated literally as board stack but more commonly associated with dowel laminated timber (DLT).	+	Nail laminated timber (NLT or also called nail-lam) uses standard dimension timbers (normally 2" x 4", 6", 8" or 10").

In German it may be referred to as nail brettstaple, which is translated literally as a nailed board stack but more commonly is associated with dowel laminated timber (DLT) rather than nails.

−	In the US NLT qualifies as a heavy timber product as a result of the number and length of nails and is used for roofs and where slightly deeper, for floors as well as for vertical wall elements. Where used vertically as ~~shearwalls~~ or diaphragms it may have plywood or OSB added to one face to provide improved shear capacity. In the horizontal NLT panel depths of about 100mm can span in a single direction up to around 3.5 metres, increasing to about 8 metres if depths increase 3 fold. Due to their massive wood heavy weight nature they can be used as an alternative to concrete slabs or steel decks in commercial and institutional buildings, as well as residential buildings. Fire rating is likely to be similar to cross laminated timber (CLT) products (normally designed to FR 30,60 or 90 minutes), though in the case of NLT the metal connections should also be protected, for example through the use of sacrificial timbers for charring rate or gypsum board cover. The types and quality of timbers used will also impact fare rating, so in each case specific product designs should be checked against relevant standards, such as ISO 834, EN 1995-1-2, EN 1991-1-2 and in the US chapter 16 of NDS and AWC TR 10.	+	In the US NLT qualifies as a heavy timber product as a result of the number and length of nails and is used for roofs and where slightly deeper, for floors as well as for vertical wall elements.

−	The main advantages of the product are that it can use relatively low grade sawn timbers from a variety of species, which are readily available in standard dimensions and does not require complex machinery to create panels, which can even be made on site. Although it is classified as a heavy timber product it is in comparison, relatively lightweight and easier to handle than concrete and steel alternatives.

New page

Nail laminated timber (NLT or also called nail-lam) uses standard dimension timbers (normally 2 x 4, 6, 8 or 10). The individual members are laid on edge and nailed to the next timber with a relatively high number of strong nails, these give it the strength to qualify as a massive wood product.

In the US

placed on edge with individual laminations mechanically fastened together with nails or screws. The boards are nominal 2x, 3x, and 4x thickness. Width is typically 4-12 inches. NLT gets its strength and durability from the nails/screws that fasten individual pieces of dimensional lumber into a single structural element.
