Usage of Membran in Roofs by Order:

They are waterproofing covers produced through the modification of bitumen (asphalt) by Polymer-based plastics, and together with carrying equipments.

Bitumens are grouped as such:

1. Penetration Bitumens

2. Oxidized Bitumens

3. Polymer Bitumens

Polymer Bitumens are divided into two as Plastomeric and Elastomeric .

Plastomeric Bitumens are synthetic rubbers that are produced through APP modification, and that lengthens the life of the material by protecting it from the Ultraviolet impacts.

In this type of our membranes that are the ideal preference in the temperate zone Atactic Polypropylene (APP) with thermoplastic resin is used to increase the resistance of bitumen. And fiberglass or polyester felt is used as carrier to increase the physical strength of the membranes. It is easy to apply by torching and hot asphalt.

Elastomeric Bitumens , however , are synthetic rubbers that are produced through SBS modification, and that lengthens the life of the material by protecting it from the Ultraviolet impacts.

Styrene-Butadiene-Styrene (SBS-artificial rubber based polymer that has very highly elasticity) containing thermoplastic resin is used to increase the resistance of bitumen. This type SBS-added membranes that are highly resistant to aging, that have high utilization performance, protecting its stability in cold climates are used in cold climates and in mobile buildings desired to be highly elastic.

SBS gives the material a continuous elasticity even in low temperatures.

And fiberglass or polyester felt is used as carrier to increase the physical strength of the membranes. Cracking and breaking under cold weather conditions are not concerned. It is easy to apply by torching and hot asphalt.

Membranes are divided into two according to the carriers:

1. Membranes with Polyester Felt Carrier

The waterproofing membranes that are produced through using spunbond felt that weighs 150 gr/m 2 , 170 gr/m?, 180 gr/m 2 or 250 gr/m 2 are ‘ Membranes with Polyester Felt Carrier '.

They are available in thicknesses such as 2mm, 3mm, and 4mm.

2. Membranes with Fiberglass Carrier

The waterproofing membranes that are produced through using fiberglass that weighs 50 gr/m?, 80 gr/m 2 , however, are called ‘ Membranes with Fiberglass Carrier '.

They are available in thicknesses such as 2mm, 3mm, and 4mm. Both faces are coated with polyethylene.

Over the membranes to be used outdoor, natural stones – granule-shaped colored minerals are laminated. This type of membranes is called Slated membrane, and only one side is coated with polyethylene.

Another one-side polyethylene-coated product is Aluminum Folio .

Climatic conditions of the region where the membrane is to be used are primarily important in deciding to use which type of membranes.
