Some frequently asked questions about our insulations

Yes, we deliver to both commercial and private customers.
Deliveries to private customers are made against prepayment.

The minimum purchase quantity is variable, depending on the requested material.
The exact amount is specified in our offers.

You can use our contact form or send your order by email/fax to one of our contact persons.

We do not keep a price list because our material is not only available in sheets, but also as rolls and can be cut to meet customer requirements.

Yes, we can send samples in standard sizes on request.

The processing area on our water jet system is a maximum of 3,000 x 4,000 mm, but the cutting size is limited to the size of the different starting materials.

The tolerances depend on the respective material and its properties. It is therefore necessary to coordinate for the particular application.

We can send you safety data sheets on request.

The costs for cuts depend on the geometry of the article and the number of pieces required.

The sound absorption coefficient α is the ratio of absorbed sound energy to incident sound energy. For complete reflection α=0, for complete absorption α=1. Since the sound absorption coefficient depends on frequency, it is measured in third octave bandwidth in the frequency range of 100 to 5000Hz.

Polyurethane foam (PU) has an open cell structure and so is used as acoustic foam for sound absorption.

Polyethylene foam (PE), in contrast, has a closed cell structure with good thermal insulation properties. Because of its superior compressive strength, PE foam is often used for impact protection in vehicle interiors.

Melamine is a flexible, open cell foam made from melamine resin with excellent flame resistance and is most commonly used for thermal insulation and sound absorption.

Polyether polyurethane foam has the characteristics:

• soft feel
• flexible
• fine open cell structure

Polyester polyurethane foam has the characteristics:

• firm feel
• rough open cell structure
• and therefore a somewhat higher degree of absorption than polyether based products

In most cases, the materials are permanently attached to objects with a high-quality self-adhesive based on acrylate.

Depending on the installation situation (e.g. horizontally suspended), the dead load and the ambient conditions, some cases may require additional mechanical fixing of the sound insulation materials.

Powder-coated surfaces with lotus effect may cause adhesion problems. Talk to us if this occurs.

Heavy foils without self-adhesive system have a high dead weight and so are permanently attached using two-component polyurethane adhesive from our range.

Always make sure to read our instructions on processing for use.

We only use continuous filament (textile glass fibres) as man-made mineral fibres (MMMF).

The continuous filaments in our thermal insulation materials are produced from suitable raw materials in a process called mechanical drawing. This results in an almost uniform, generally round, cross-section, with a fibre diameter of 5 - 24 µ.

Under both German and EU laws, our continuous filament products are currently exempt from classification in a health risk category.

We cannot rule out that the handling of our thermal insulation materials may cause itching. As a precaution, we would recommend using appropriate protective equipment such as dust masks, goggles, long work gloves and use hand cream when processing and fitting our products.
