Silica – Nonwovens

Product Description: 

Silica Needlemats are made from special glass fibers with a filament diameter of 6-9 microns. They represent a modern product generation that, in any aspect, meets with all stringent requirements as to temperature consistency and environmental health standards. Silica glass fibers consist of nearly 95% SiO(2). Because of their low thermal conductivity they are the ideal raw material for the production of flexible insulation mats formed mechanically without the use of chemical bonding agents. These mats keep a very high chemical and physical stability up to 1,800 degr. F. (For application temperatures not higher than 1,200 degrees F, we recommend the more cost efficient E-Glass Needlemat).

The easy handling of the mats allow the cutting of the material into any desired shape and form.

Definition Basalt Rebar

From Wikipedia, the free encyclopedia

Rebar (short for reinforcing bar), also known as reinforcing steel, reinforcement steel,[1] is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and hold the concrete in tension. Rebar's surface is often patterned to form a better bond with the concrete.

The above description from the Wikippedia does not include Basalt, but nowadays, Basalt is available, as well.

Below are a few highlights utilizing Basalt instead of e.g. the commonly used Steel:


  • Higher specific strength
  • Approx. 10% of Basalt Rebar needed to achieve the same results as with Steel Rebars
  • Resistant to corrosion or deterioration caused by natural elements
  • Alkaline and acide resistant
  • Same thermal expansion as concrete, reducing the formation of cracks

Suitable Applications: 

  • Concrete
  • Highway
  • Construction

Basalt – CNC


Given the right form, basalt can be also machined with CNC equipment.

The picture illustrates a basalt board which we asked to get machined in a shop in USA.

This allows for a lot more applications and to venture into completely new markets.

E.g. Gaskets for motors, appliances, doors, ovens, or for  insulation of pipes, just to mention a few.

The board we offer can certainly also be dye-cut or cut with a "box cutter".

Basalt Mesh Fabrics

Mesh Fabric, made from Basalt fiber

As its preferred use is in outdoor applications, it is also considered to be a Geotextile.

Technically, not all meshes are woven; the first picture is a leno woven, but picture two, three & five are not woven;

Following advantages make this product superior over an E-Glass Mesh: 

  • Ecologically safe
  • Withstands very high temperature of molten asphalt
  • Very high strength and durability
  • Alkali-resistant and chemically inert
  • Corrosion-resistant
  • Will not damage tires if exposed to road surface
  • 2.7 times lighter than metallic mesh, for easier handling and reduced transport costs
  • Up to 47% increase in asphalt surface life on roads and highways.

Basalt Geo-Mesh is also ideal for soil and embankment stabilization and land-fill coverings, due to its high strength and environmental and ecological safety.

Meshes can be offered with and without resin coatings.

Standard constructions:

5mm x 5mm (1/4″ x 1/4″) squares

10mm x 10 mm (3/8″ x 3/8″) squares

Basalt Board

A Needled Blanket is compressed into a board with the help of a Phenolic resin. This value added treatment allows the material to be dye-cut or molded into almost any common shape.

While the board could be used in almost identical applications as the Basalt Needlefelt is used in, it also allows for additional markets, such as  in pipe wrappings, ladles, furnaces, or high temperature insulations, up to approximately 1,600 degrees F in general.

In highly competitive markets, this board can be used in conjunction with insulation materials of lower K-values, at lower cost. In those instances, the board serves as high temperature facing layer, with the purpose in lowering the temperature far enough for the second layer to withstand. In this example, the second layer could be a fiberglass Needlemat. In other instances, there may be even a third and a fourth layer.

In order to recommend the best insulation system, it will be required to know exactly about the environment this material will be facing.


  • Ovens
  • Kilns
  • Furnaces
  • Whiteware
  • Transportation
  • Refractory applications
  • In general for application up to 1,600 degrees F

Basalt Unidirectional Fabrics

Basalt Fabrics in general can be applied where E-Glass, sometimes S-Glass or Carbon Fabrics can be used, as well. As Basalt is more expensive than E-Glass, but cheaper than Carbon Fibers, typically it finds implementations, more suitable to its particular properties and fills an important gab when it comes to cost-performance ratios.

You can find a comparison to E-Glass, S-Glass or other materials by clicking here: Basic Comparison To Other Fibers.

Knowing how Basalt compares to other fibers allow to precisely engineer an optimal solution, which could also be in form of a hybrid (combining Basalt with other Fibers made from Glass, Carbon, Kevlar, etc.)

An Example of an Engineered FRP. 

In Fiber Reinforcement Products (FRP) the engineer chooses the fiber, based on the desired outcome. E.g. if lighter weight requirements at identical strength to currently used fibers are required or if higher strengths are necessary while staying within the weight specifications.

There are other examples relevant to durability, corrosion resistances, break strength, chemical resistances, thermal applications, etc.

Engineers often choose unidirectional fabric when strength mostly in one direction only is required. This then presents a more lightweight and cost attractive solution.

Standard offering: 

Weights: 5.9 oz/syd – 8.8 oz/syd

Widths: 23.6″

Length: 54.5 yd

About Multi Axial Fabrics

Multi-Axial Fabrics consists of a numerous amount of layers stitched together.

Each single layer may be of a different, individual construction, whereas it can be a woven fabric, a unidirectional fabric or any other version. The choice of materials may be different. E.g. it could be a combination of Glass & Basalt

, or Carbon & Kevlar & Glass.

In Multi-Axial Fabrics, often the manufacturer takes advantage of positioning the layers of fabric to where the main fiber direction points into a different angle to the previous or the following layer.

This allows for optimal utilization of the fiber properties, in most cases the strength requirements.

Following graph illustrates one example of a Muli-Axial Fabric:



A four layer Multi-Axial Fabric would be called a Quadraxial fabric. it Can have the main fiber direction of the layers point in 3 or four different directions (degrees).



The following graph illustrates the necessary stitching-assembly process.
