THE FELT INNOVATOR

COMFORTABLE SOUND INSULATION, IN A CLASS OF ITS OWN!

In residential construction, impact noise nuisance from floors separating houses is a source of annoyance. Especially (older) homes with wooden floors usually have lousy sound insulation. For acceptable living comfort, an improvement of both airborne sound insulation and impact sound insulation is an absolute necessity. The maximum load on the floor and the installation height are a major obstacle here. Nevima has developed a system in several versions for this purpose, which still provides excellent sound insulation with a limited installation height. Due to the unique composition, these Nevidek systems perform at least one class (+5 dB) better compared to the usual dry systems! In combination with the IVI Metal Ceiling, the new construction requirements can be easily met. All Nevidek cladding can be combined with underfloor heating systems.

Description

The Nevidek Dry-build System for floors is made up of a resilient layer of Nevidek Kokos 300 and a plating (top layer) that is provided with a liplast. The Nevidek Coconut 300 is made of bio-based coconut fibers and latexed on both sides. It is a durable, shape-stable and permanently elastic felt. At high (peak) loads, the fibers remain intact and even with prolonged (over) loading, no creep occurs. The Nevidek Coconut comes in 6 or 12 mm.

Depending on the application, there is a choice of three systems: Nevidek Basic, Nevidek Pro or Nevidek Pro Plus.These systems have a top layer of two interglued cementitious glass fibre reinforced mineral plates and are equipped with a 50 mm lip weld.

Nevidek Basic has a total installation height of only 24 mm! This consists of an 18 mm Nevidek Basic plate and 6 mm Nevidek Coconut. Good insulation values are achieved with a very thin system. For uneven surfaces, such as a plank floor, or for higher insulation values, the 6 mm Nevidek Kokos is replaced by the 12 mm one.

A class higher is the Nevidek Pro system. This is made up of a 24 mm Nevidek Pro plate with a 12 mm layer of Nevidek Coco.

For the highest sound insulation, the Nevidek Pro Plus system is chosen. This consists of a 24 mm Nevidek Pro plate and a 2x12 mm layer of Nevidek Coco.

The Nevidek Dry-build System has the following advantages:

• Dry processing
• High insulation values
• Limited installation heights
• Suitable for finishing after 24 hours
• Provides a flat surface
• Completely moisture-resistant (unlike plaster-bound
• products), so also to be applied if the premises have not yet been
• is completely wind and waterproof.
• Very hard, wear-resistant (even after several replacement of
• carpeting), dimensionally stable, flat and impact-resistant.
• Non-combustible (class A1), which makes the Nevidek Pro
• systems are even suitable for escape routes.
• Contains no quartz-containing substances.
• Very high improvements possible, on
• impact noise up to 19 dB and airborne noise up to 10 dB.

Applications

With Nevidek, high-quality floating floors can be made in a 'dry' version. The Nevidek systems have been developed for light load-bearing structures such as wooden floors. However, due to the composition, the systems are also very suitable for use on concrete and floors that are heavily loaded, such as in the hospitality industry. Most common floor coverings can be applied directly to the boards. Tiled floors can be used on the Nevidek Pro system in residential construction and on lightly loaded office floors (class A).
