Future Material: Typar ???

[IndyDan]

While attending a home show, I found two products that may have some future hammock benefits:

First, is a product used for roof deck protection called “Deck-Armor” by GAF.

The second is a house wrap. The product name is Typar made by Fiberweb.

Fiberweb has a number of different product lines.

Has anyone used either of these materials?

how would something like this be different than tyvek? waterproof/breathable. it looks like it still has the stiff paper-like feel.

[IndyDan]

Good Point, warbonnetguy

If you wash tyvek and use a fabric softener (Downy), it does help eliminate some of the paper feel.

This link provides the comparison to tyvek. http://www.typar.com/pdfs/HouseWrap_comparison.pdf


I was thinking about using Typar for a winter tarp due to air barrier factor and strength. Other uses: undercover, side or end covers for tarp, or higher weight load capacity for a bridge.

I wonder if you can sew this material?

If I did the math right, it's effectively 3 oz per sq. yd.

Yup, it's listed as 3.1 oz/yd^2 in the pdf.

As for the sewing aspect, it should behave pretty similar to tyvek - they're both random-oriented strand based products. Perhaps different waterproofness and a slightly stiffer material, but I think they're inherently the same material.

Brian... at first glance it looked like Tyvek with reinforcement fibers when I looked at the video. Much like the rip stop fibers in rip stop nylon... I'm guessing. The terms waterproof, water resistant, and breathable are used so liberally(?) these days that I have a hard time figuring out just what they mean by them... kind of like large, medium, small, and extra large drinks.

I called three building contractors in the area (friends) and asked about the different between tyvek and typar. All three stated typar did a better job of stopping air infiltration and was stronger. All recommended the typar product.

I did a searched on typar and found its a Dupont product.

“Typar®, a spunbonded nonwoven fabric made of continuous polypropylene fibers, has high tensile properties and excellent water permeability.”

It has many more commercial uses than tyvek.

I sure don’t want to advertise this product with the trade name all over a tarp!

according to the video, typar has "optimum breathability" probably somewhere between mosquito netting and plastic sheet

This may not be practicable or workable material for main components (hammock bodies or tarps), but for reinforcement areas I think it could be a cost savings, strong and lightweight answer.

Example of use:

As a flat webbing material on the sides of a bridge hammock.
Or
Support material sew into a lightweight material.

I think (IIRC) that it's stiffer than Tyvek, so it may make it bulkier and less advantageous to pack, but as IndyDan suggested, it may work well in a pinch for reinforcement areas.
