2.product description


Housewraps is kind of air infiltration barriers, which can reduce air infiltration and improve energy performance. Housewrap can operate as air infiltration barrier while not forming an impervious vapor barrier. When housewraps are placed over the exterior surface of the wall sheathing, moisture vapor can escape from the frame wall cavity while reducing convective air movement in the insulation, thereby maintaining the composite R-value of the wall. The greater the exterior air movement, the greater the benefit.

Housewrap can be divided into two basic categories: perforated and nonperforated. Perforated products are either woven polyethylene, woven polypropylene, spun bonded polypropylene, or laminated polypropylene film. Compared with nonperforated wraps, these materials are more impervious to moisture vapor migration, and their "micro-perforations" allow vapor migration and diminish their vapor retarding properties.All the perforated housewraps, except the polyethylene films, are further coated with either polyethylene orpolypropylene for added air infiltration resistance.

In contrast, nonperforated housewraps are either spun bonded polyethylene or fiber-mesh-reinforced polyolefin. Water vapor can pass through these materials, while air infiltration is inhibited.

In addition to air leakage resistance, permeance, and moisture resistance, UV resistance and strength should also be considered. UV exposure time can range from 120 days to more than 1 year. We can add antioxidants and UV stabilizers to the housewraps. However, the housewrap should be covered as quickly as possible to avoid UV degradation, also other unrelated damage to the membrane can be avoided.

Strength of the housewrap is an important factor to consider as wind conditions or adverse jobsite handling can tear or puncture the material during and after installation. The strengths of housewrap can be judged on three levels: 

tensile strength, 

tea rstrength, and 

burst strength.

These are the material's ability to withstand damage from pulling and stretching; withstand tearing at nail and staple locations, and separation of material fibers, fabrics, or films. 

In northern heating climates, where interior vapor barriers are the norm, a highly moisture vapor permeable housewrap may be required. In hot ,humid, cooling climates, where an interior vapor barrier is not required, a housewrap with a low air leakage rate may be preferred. In low-wind environments, a low-strength material may be selected.

6. Zhengbang Frequently Asked Questions


Can you supply tarpaulins with specified size and weight?

Yes. We can manufacture with particular sizes and weight, but your order should be at least 10 ton, otherwise there will be too much waste in lamination. Our lead time is generally 1 month upon receiving your deposit, and minimum quantities will apply; please contact us for details. For immediate requirements, we can supply you with ready-made tarps in very rare occasions.

Why is there a seam on my cover?

There are seams on most tarps as in most cases only 1 piece without welding other pieces can hardly fabricate a tarpaulin of specified sizes. On some of the smaller tarps with sizes of 1 direction less than the width of woven fabric rolls, a seam may not be necessary. 

Do you offer a guarantee to the lifespan of your tarpaulins?

No. Because tarpaulins are subject to different weather and put to so many different applications, the length of time can’t be guaranteed. Generally speaking, a heavier grade tarpaulin and/or tarpaulin with UV stabilizer may last longer than an economy grade tarp. 

We cannot be held responsible for damage caused by wear and tear, or degradation through UV. Please also bear in mind that eyelets can come under a lot of pressure, and so any stress points should be reinforced. Even for heavy duty tarps, no guarantee is given to the eyelets. Please also avoid any sharp edges and constant friction, because this can reduce the lifespan of your tarps.

What intervals are the eyelets? Can I have smaller intervals?

Eyelets are on all 4 sides and spaced all around the hemmed edges with about 1 meter interval, or 1 feet or as per customer specification. However the cost might be a little higher if you want smaller intervals.

How long can I receive my order?

Generally standard orders of 1x40’ container are up to 5-7 working days to load the containers from date of order, but since there are also other orders, you may have to wait, and the general lead time is about 1 month. 

Are your tarpaulins guaranteed?

Yes, all our products are frequently tested in the process of production, and are guaranteed to be free from defect at the time of purchase. Therefore if your tarp has a defect due to a manufacturing fault, please report such problems to us with a digital photograph of the fault However, we will not accept any responsibility for the misuse of our tarps for warranty claims.

The tarpaulin I received is shorter than the size stated.

There are cut size and finished size in tarpaulin industry. Cut size is the industry’s standard way to manufacture tarps. When you lay an order of tarpaulins, e.g., 4m x 5m, we cut the woven fabrics rolls into 4m x 5m cloth, with many pieces combined, and that is the cut size. This material is then made into a tarpaulin. However, in the process of making the hems you will have to fold about 5 cm on each side, and every time when welding two pieces together another 5 cm will be consumed, and that makes the finished size at least 10 cm shorter than cut size.

What methods of payment do you accept?

We accept TT and LC payment. The payment is usually 30% deposit and balance at sight of B/L.
