COVERING MATERIAL FOR SHELTER
THE AMAZING PROPERTIES OF POLY FLEX EPDM WATER PROOFING FORROOFS OF ALL KIND
This Single-ply black membranes are light weight and has exceptional long lasting elasticity permitting the materials to withstand followings.
- Building movement.
- Expansion - Contraction of Building surface.- High resistance to Ozone and weather as they are known as "Crackless Rubbers"- Low Specific gravity - lightest among all rubbers.- Widest Temperature range from - 50'C to + 150'C.- Excellent Steam and Water Resistance.Even after 20 years EPDM Roofing Material maintains good properties and appearance.
MAIN ADVANTAGES OF "POLY FLEX™" EPDM WATER ROOFINGS
A.
THE SUPERIOR PROPERTIES OF EPDM WATER PROOFING.The life of any building is dependent of the designer recognising and considering all the factors relevant to its location, shapes, and function of the building. Reliable roofing is the most important part which devides the quality & ultimately the life of the building. An efficient roof sheeting should never allow even traces of water to pass through it at any given point and should maintain this characteristic over a long period of time. It should withstand slight moments of the structure, bad weather, chemical degradation and mechanical stress and strains.EPDM is the perfect solution which meets the stringent requirement of good water proofing roof sheet. In the long run it is a more for more economical than traditional water proofing systems.
B.
"POLY FLEX™" EPDM SHEET HAS MORE WATER PROOFING POWER THAN CONVENTIONAL MATERIAL.EPDM sheet (with a thickness of 1.2 mm) is 22 times more than asphalt and 59 times more water proofing than PVC sheet.
C.
"POLY FLEX™" EPDM SHEET WILL TAKE THE "MOVEMENT" OF THE STRUCTURE:-Since EPDM sheet can be stretched (approx. 400%), it will not tear, crack or split but returns to the original position, without damage to the membrane. The EPDM SHEET has an unfailing flexibility.
D.
"POLY FLEX™" EPDM SHEET WITHSTANDS EXTREMES OF TEMPERATURE:-Because of serviceability over a wide range of temperature (-50° to + 150°C), EPDM sheet does not embrittle in freezing weather nor soften in hot weather.
E.
"POLY FLEX™" EPDM SHEET MINIMAL EXTRA LOAD ON YOUR ROOF:-EPDM roof sheet is one of the highest roof membrane materials (with a specific gravity of approx. 1.15 kg/m²). It is highly suitable for light weight structures and puts negligible extra load on roofs to be water proofed.
F.
"POLY FLEX™" EPDM SHEET LASTS FOR MORE THAN 20 YEARS:-Presently in our country, asphalt based coating is employed in many buildings to protect the roof from leaking. However, the life of such waterproofing is limited and the coating has been replaced every 2 to 3 years. Because of expansional water & weather resistance of EPDM, the roof sheets based on EPDM are known to last for more than 20 years.
G.
LITTLE OR NO MAINTENANCE IS REQUIRED FOR THE EPDM WATER PROOFING SHEET:-As the EPDM Rubber Sheet does not deteriorate due to weather, heat, sunlight and oxidation virtually no maintenance is required for the roof.
[DURABLE!]
H.
RESISTANT TO MOST OF THE ACIDIC AND ALKALINE CONDITIONS FOR WIDE RANGE OF TEMPERATURE:As the EPDM rubber is highly saturated polymer, it has better chemical and environmental resistance than other available polymeric materials. This can be used in chemical plants for their drainage and canal systems to avoid seepage through the RCC / CONCRETE work which in turn can damage surrounding fields.


"POLY FLEX™" EPDM ROOF CAN BE FIXED IN TWO WAYS.
1.
BALLASTED In this method, the water-proofing sheet is simply fitted over the roof and fixed only at the perimeter with the help of contact adhessive. To prevent the covering from being lifted and blown away by strong winds, it is covered with ballast. The sheet should be loaded with ballast immediately after laying. Ballast should be round, washed stone 20-40 mm diameter (usually rounded river washed pebbles are used for this purpose).The ballast weight should be calculated by taking into consideration the design permissible loading capacity of roof.
2.
FULLY ADHERED SYSTEM: Bonding is appropriate when structures are too light or roofs are too steep for ballsting. This method can be bonded to smooth wood, concrete, steel, aluminum, rigid insulation, clean and free of Oil, Grease or other contaminants.In this method , the main area of covering is bonded to its substrate with slow curing adhessive . The surface regularities of the old roof must be removed before applying the covering.First the roof sheet is placed with in proper position , and adhessive is pured directly from the container or is applied with the brush or roller . The rubber sheet is than unrolled over the fresh adhessive layer and is roller worked until it is flat and free of wrinkles.SO IF YOU ARE LOOKING FOR A STRONG. FLEXIBLE WATER PROOF SYSTEM OR FOR ANY WATER PROOFING CONSULTATIONS KINDLY CONTACT OUR TECHNICAL DEPARTMENT.

INFLATABLE FLOATS
1)The functional, lightweight, foldable watersports boards are constructed from the same sturdy materials used in military/commercial inflatable boats, making them durable and UV resistant.

2)The greatest appeal of the boards is that they can fully deflate for travelling, allowing you to fit one easily into a large backpack.

3)You can then quickly inflate it with a hand pump when you're ready to surf.
[we might want to change the idea of inflating it with a pump because it is too time consuming. so i suggest we adopt the idea of sucking in external air to inflate the thing. yup. dont have to research on this cus i think we can just be very brief in our explanation, saying that we press some button to inflate the thing with external air. yeah. something like that lar.]

4)The fact that it's lightweight, soft and super buoyant.
