Description :

Quartz Alushield are elastomeric water proofing membranes, manufactured in an advanced continuous calendaring process by saturating and coating a composite carrier with a water proofing compound made of a special grade of bitumen, modified with SBS polymers. While the SBS polymers enhance the thermal, mechanical, and aging properties of the membrane compound, the mechanical characteristics of Quartz Alushield are established by the composite carrier made of non-woven Polyester armoured with Glassfiber filaments, which acts as the reinforcement that provides the membrane with the profound mechanical properties of the Polyester and the prominent dimensional stability of Glassfiber mats.

Major Features : 

• Substantial Dimensional Stability.
• Good Resistance to Chemicals.
• Superior Isotropic Mechanical Properties.
• Significant Compound Elastic Behavior.
• High Performance under a wide range of temperature fluctuation.

Uses :

Quartz Alushield can be used for roofing, waterproofing and vapour controling applications with high dimensional stability requirements and subjected to considerable movements induced by stresses , and to critical weathering conditions. Quartz Alushield membranes are particularly recommended for the following Areas of Applications :

• Vapour barrier layer under pitched roof tiles.
• Flat and sloped roofs protected applications for medium and large areas.
• Foundations and underground structures with critical site conditions.
• Protected waterproofing of roof decks or substrates subject to movements, such as metal decks, insulation boards, tiles, etc.

Surface Finish :

The lower surface of Quartz Alushield is laminated with a Polyolefinic film while the upper surface is covered with Aluminum finish.

Method of Application :

Quartz Alushield is usually applied by using a propane torch or a hot air generator as well as by mechanical fastening. It can also be applied using special adhesives in cold or hot applications.
The substrate surface must be clean, dry, smooth, and free from any irregularities. According to the surface conditions, a coat of Technobit Primer maybe required prior to the application of the membrane.
Quartz Alushield can be applied to the substrate fully bonded, semi bonded or loose laid, and the method of adhesion to the substrate shall be decided according to the waterproofing system design. Side laps should be from 8 – 10 cm, while end laps should be from 12 – 15 cm. For more information on application refer to Technobit application guide.

Storage & Handling :

Quartz Alushield rolls should be kept in an upright position in a flat, properly ventilated and sheltered storage area.
