Application

OmniFit® Slab 35 is typically used for the thermal and acoustic insulation of a wide variety of constructions such as timber and metal stud partitions, timber frame walls, between rafters and timber floors.

Description

Knauf Insulation OmniFit® Slab 35 is a glass mineral wool insulation slab, designed for use in multiple applications in both timber and steel frame construction.

Offering thermal conductivity of 0.035 W/mK as well as acoustic insulation.


It is non-combustible, achieving the best possible Euroclass A1 reaction to fire classification and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.


Features and benefits:

  • Good thermal performance.
  • Provides a higher level of thermal performance than alternative flexible slabs.
  • Manufactured with ECOSE® technology, an innovative, bio-based binder that helps make the product soft and easy to handle.
  • Non-combustible A1 Euroclass Reaction to Fire classification.
  • Good sound absorption characteristics.
  • Multi-purpose product which can be used to insulate a wide range of applications, meaning less products on a vehicle and on-site.
  • Manufactured size allows friction fitting between common stud centres without any cutting and waste on-site.
  • Indoor Air Quality - Eurofins Gold achieved.


Standards and certification:

OmniFit® Slab 35 is manufactured in accordance with BS EN 13162, ISO 50001 Energy Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management systems, as certified by TÜV Nord. All our Glass Mineral Wool products have been awarded the DECLARE ‘Red List Free’ label. Having the ‘Red List Free’ label means that there are no ingredients in the product that are on the red list - including formaldehyde or phenol.


Real performance:

Glass and Rock Mineral Wool are easier to install correctly than other insulants such as rigid boards because they adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.


Handling and storage:

OmniFit® Slab 35 is easy to handle and install, being lightweight and easily cut to size, where necessary. OmniFit® Slab 35 is supplied in recyclable polythene packs (4-LDPE) which are designed for short term protection only. For longer term protection on site, the product should either be stored indoors, or under cover and off the ground. OmniFit® Slab 35 should not be left permanently exposed to the elements.
