Production of fiberglass mesh for construction

Dear Sir,

Please check the Elsevier Magazine Publishing Company for their Magazine called "Reinforced Plastics". once a year, they focus on the Construction Industry and the applications of Fibre-reinforced plastics. They also provide free copies to those qualified.

Best Regards,

Dear Mike,

Thank you very much indeed, for this information.

Best regards,

Mario

I have experience with fiberglass materials in a variety of forms (roven, chopped strand, woven, needlepunched, wet laid, and more). I do not understand specifically what you need for construction and machinery applications but will be pleased to assist you on a very timely basis in the CR4 Forum.

PS: Do you really want to go find copies of some Elsevier Magazine in a library and then read all of them to find construction issue which may (or may not) contain the information you desire? Seems like a time-consuming and laborious means to your answer. ;-)

First of all thank you very much for your time. Actually I realize the way how I phrased my subject caused confusion,. I will put in simpler form : I am interested in Technology (process and equipment) fibreglass mesh production. This mesh is used in constraction for Exterior Insulation Finishing System and for many other porposes.

I hope I made my self more clear. Maybe you could give more details in this respect.

Very best regards,

Mario

Are you looking to make a product similar to either of the pictures shown here?

This product is made from glass fibers that are thermally extruded and drawn with high velocity air. The fibers have very small diameter, are produced in large quantities at one time and collected on a moving belt. There are similar products made with chopped glass fibers but the fibers are larger diameter and can be very expensive. It depends upon your application which is the best fit for your need.

This product may have some insulating value but it is really meant to be used with other materials (stucco or other mineral-based products) to act as insulation.

Does this help? If you have a picture of a product, that will help. And, if I have shared the right product, that will help all of us provide you with more information.

This the product which I am interested in.

Regards,

Mario

Mario,

To the best of my knowledge, the most cost-effective means to produce these products is to extrude a performated film that is drawn through a tenter frame. When the material is still molten (or, still quite warm), the tenter frame stretches the material in both the machine (roll length) direction and the cross (roll width) direction. Depending upon the size and number of perforations and the amount of stretch, the aperture (hole opening) of the film can be adjusted to suit your needs.

A similar product can also be made by weaving fibers together in a loose construction. The crossing fibers, however, must be bound with heat, pressure and/or an adhesive. This process has benefits in making a very porous material but it does not have much strength and may be ery expensive.

There may be other ways to make this kind of product. Anyone else have any ideas?
