Product Details

Polyester Reinforced TPO Roofing Sheet

Polyester reinforced TPO waterproof sheet  is a type of polymer waterproof material that using polypropylene(PP) and rubber as main material, adding polyester fiber in the middle  as reinforcement to enhance product property. It maintains high tensile strength and  good durability, also can be recycled throughout its service lifetime.

Product advantage

1.Convenient operation: well adapted to wet substrate or  under different weather condition, after construction, the product can be exposed to  the air without any protective layer; Re-welding is 

operable.

2.Long service life: High aging resistance, tensile strength  and elongation.Anti-mildew  and alga.

3.High  sun rays reflection when using white color TPO.
4.Environmental  friendly:Product  contains  no chlorine, heavy metal nor harmful elements to the plant roots

Construction procedure  scheme:
 1.Mechanical  Fastening
 Construction procedure scheme: (see the sketch map→)
 

image017.png

 
1.Substrate  treatment –2.‚Paving  vapor barrier –3.ƒFastening  insulating layer– ④Paving waterproof membrane – ⑤Fastening waterproof membrane – ⑥Hot gas  welding waterproof membrane.

1)Clean and fix the substrate, make it flat,  smooth, dry, clean without  any hollow, sand, or  crack.

  • Paving  TPO membrane: pave the membrane according to the alignment line, keep the  membrane straight and  

   smooth without  over-stretch or wrinkle.

  • Membrane fastening under overlapping  area: Use fixings to fasten the membrane.

  • Hot gas welding: Use auto hot gas  welding machine or handheld hot gas welding gun and silicone rubber roller

   to weld the TPO membrane.


2.Full-adhibiting  Method
 Construction  procedure scheme:
 

image019.jpg

 
1.Substrate  treatment–‚2.Snap  lines for alignment –ƒ3.Paving  waterproof membrane–④Paint adhesive–⑤Rolling to exhaust gas-⑥Hot gas welding  waterproof membrane

1)Substrate adhesive can be painted on  substrate or on the downward side of TPO membrane. Paint the adhesive evenly  with no blank spot or pile-up (can adopt strip adhibiting method, spot  adhibiting method and border adhibiting method as well)
 2)Overlapping area shall adopt hot gas  welding method. Weld the long edge first and the short edge after. Full  adhibiting method is suitable for concrete substrate of various buildings. The  construction technique and key process are the same as other high polymer  waterproof membrane that use adhesion bonding method.
 Note:   TPO membrane with self-adhesive layer adopts pre-paving or wet-paving  methods.

 

  • Construction Attentions: At welding, clean the welding area, no water, no oil and  no contamination is allowed.Before a formal welding, testing welding shall be  carried out, to confirm the welding temperature and speed.

 

Storage

  • Flat-wise  storage ,the stack height should not be over 5 layers,

  • Up-right  storage, the stack height should not be over 2 layers.

  • Do not  contact with acid, alkali, oil and organic solvents.

  • Storage  temperature should not exceed 45℃, shelf-life is not  more than one year.
