Innenraumlatten

Innenraumlatten, commonly known as interior laths, are thin, narrow strips of wood or other materials used primarily in the construction and finishing of interior walls. They serve as a base for plaster or other wall finishes, providing a stable surface for even application and a textured appearance. Historically, laths were made from wood, but modern versions may also incorporate metal, fiberboard, or synthetic materials, each offering distinct advantages in terms of durability, fire resistance, and ease of installation.

Wooden laths, traditionally used in Europe, are typically 10 to 20 millimeters wide and 1 to 2 millimeters thick, with a characteristic ribbed or corrugated surface. They are nailed or screwed to wooden studs or metal framing, creating a grid that helps plaster adhere securely while allowing for minor settling without cracking. Metal lath, often made from expanded metal mesh, is another common variant, prized for its strength and resistance to moisture and pests. It is frequently used in areas prone to humidity or where additional structural support is required.

The installation of Innenraumlatten involves securing the strips to the wall framing at precise intervals, usually 2 to 3 centimeters apart, to ensure proper coverage. Once the laths are in place, a mesh or fabric reinforcement layer, such as fiberglass mesh, is applied over the surface before plastering. This reinforcement enhances the wall’s strength and prevents cracks from forming as the plaster dries. The final layer of plaster is then smoothed or textured to achieve the desired finish, ranging from smooth walls to decorative patterns.

Innenraumlatten are widely used in traditional and historical restorations due to their ability to replicate older construction techniques. However, they are also employed in modern construction for their functional benefits, including improved insulation, soundproofing, and fire resistance. Proper installation and material selection are critical to ensuring longevity and structural integrity, making Innenraumlatten a versatile choice for both new builds and renovations.
