Typar vs. Tyvek: What Is The Difference Between Them?

Are you planning any exterior remodeling and is questioning a house wrap?

Probably you are investing a lot of money in remodeling, repairing structures or building. You might be wondering if you need a house wrap for a construction project!

Yes! It is a basic requirement for you. Especially, if you are living in a part of the country, where weather conditions are harsh, you have to make sure that your local building structure or any new siding doesn’t get damaged. And you can save yourself from future worries by simply using a house wrap.

Besides climate, all exterior finishes always allow some water to penetrate and this water affects the roots of your house making a big mess for your construction project. House wrap protects your home form this water to enter into the roots and cavities of any structure.

House wrap always serves as a multi-purpose by wrapping itself around your building. It also stops air and keeps your wall safe from moisture.

House wrap is very effective in keeping your building breathable. It does so by allowing water vapors to pass through.

The most commonly used house wraps are Typar and Tyvek. These water-resistant barriers (WRB) are the replacement of the early use of asphalt-treated paper.

House wraps are very light-weighted material making it easy for contractors to apply!

You want to choose the best one among Typar vs Tyvek. We will discuss and compare both house wraps in detail!

Why Choose The Right One Between Tyvek and Typar Home Warp?

Always be careful about the selection and installation of a house wrap. A wrong selection of it will only bring you disasters and misfortunes. Like you might be thinking that why to care about any specific house wrap and just select any of them because my siding does not like anyway. This is completely wrong.

If you will not select your house wrap carefully, your WRB can leak and easily get into the cavities of your building walls and roots. And by the time you will know about it, the damage will be more severe.

There are different installation requirements for house wraps. If you select a wrong one, it will be impossible for you to install it properly, whether you choose a typar or a tyvek.

Remember that many of the claims about Tyvek or Typar are just misleading and you can end up buying a wrong one! The wrong choice will only protect your home for some time but the results will be mold growth and the damaged form of your house walls.

It doesn’t matter if you are doing a DIY project or going to hire a contractor, always choose your house wrap be being very careful.

What is Typar?


Typar is a very well-known house wrap and will protect full protection to your home from all kinds of water, dust, cold, wind and it also claims to protect the building structure from ultraviolet radiation (UV).

Typar is a polypropylene. It is designed in such a way that it reduces the risk of damage due to any moisture or any growth in the cavity of your building walls.

Technical Background

Whether covering a breathable layer made up of polypropylene is a typar building wrap.

Tyvek vs Typar: Side to Side Comparison-2021

First, have a better understanding of which one is best and under which circumstances

Uses for Each One

The main thing to know about tyvek is that this material is highly recyclable and recycling is very healthy for our atmosphere. Tyvek is very durable under any construction environment. Tyvek will help maintain the effectiveness of a wall.

If you want to wrap many irregular shapes or have different styles around corners then tyvek is great for you because it is lighter and it is easy to handle. This factor will also reduce the installation price of your house wrap.

In the case of Typer House wrap, Typer fibers are coated with a perforated film. Typer offers a great deal at the industry level and keeps the best balance, preventing all moisture-related problems. Thus, increasing its efficiency. Its tear strength is very good and maintains a good resistance against climate change.

Now, let’s compare both of them!

1. Permeability range

Permanence is very important while selecting one of them. Both manufacturers claim that their permeability range falls between the ideal range that is 10-20. But keep in mind that it also depends on the conditions and weather of the location where you are starting your project. The permanence of any house wrap can always be calculated by following 3 main factors.

  • Weather.
  • Building Structure.
  • Location.

While comparing Typar and Tyvek, there is a very small difference between permanence power. But you should always have expert advice as their permeability can increase or decrease spending on the above factors.

We can say that perm rating is a combination of water hold out and breathability. An ideal permanence will have good breathability that will allow water vapors to escape and will also maintain its efficiency for blocking water from outside.

2. Drainage Plane and surfactant resistance

Don’ underestimate these two while choosing a house wrap. A low surfactant resistance can easily decrease the long-term durability of house walls impacting a house wrap’s performance itself. Same as surfactant resistance, the drainage plane is also important.

To prevent your walls from mold, one important factor is controlling rain. Water drainage planes used in house wraps are designed in such a way that that it prevents rainwater from entering by directing the water downwards and outwards. They are always located behind the claddings.

Surfactants are surface-active agents and these agents lower surface tension of a liquid. This will allow water to deeply penetrate the house wraps. Soaps and chemicals that are used for power wash sidings also contain surfactants and can easily damage house wraps with no surfactant resistance.

Tyvek home wrap has a drainage plane and It can easily manage a lot of water as compared to Typar. Typar doesn’t have any drainage planes and thus lowering its efficiency against holding water back.

Let’s talk about surfactant resistance. Strong power washing or cedar siding oils can be very dangerous for any house wraps. As Tyvek doesn’t have any surfactant resistance, extra oils or soaps can create a hole in your wall and thus reducing its water resistance power.

On the other hand, Typar is very strong surfactant resistant and will keep your walls dry while giving protection against soaps.

4. Thickness of material

Depth of wrap material is necessary to survive the life of a building! Any wrap must be enough thicker to have a maximum strength of resistance against any climate changes or other harmful chemicals.

Tyvek wrap is multiple times thicker. Because of its thickness, Tyvek offers good protection against water disturbance and increases the durability of material against the Heavy atmosphere

Typar’s wrap also has good depth and has an ideal permanence. But compared to Tyvek its material is thinner than tyvek making it a little less reliable. If the film of this wrap becomes damaged then it cannot resist moisture or water.

4. UV Rating

There are different claims and arguments about both wraps. Some suggest that for a better UV rating you should choose typar while others suggest that go with tyvek. A UV rating of a wrap depends on the flexibility of a material. Any house wrap will become damaged due to excessive exposure to ultraviolet radiations and its durability can eliminate.

If your project becomes delayed due to any reason and your wrap is left exposed to the sun for a longer period, sun rays will completely damage your house wraps and will no longer be able to perform.

Sun’s rays have different wavelengths and depending on it most of them are invisible to us. These radiations can be divided into 3 different groups:

  • UV-A(315-400)
  • UV-B(280-315)
  • UV-C(<280 nm)

A combination of UV-A and UV-B will always majorly impact your buildings house wraps and will cause their destruction by penetrating deeply into them.

It is always best to be careful about leaving house wrap exposed longer to the sun. But you should also choose the one having a maximum UV rating.

Tyvek provides 4 months of UV protection while Typar provides a 6- month rating of protection.

5. Resistance

A high resistant house wrap will save your house from all kinds of damages and will guard it against dust particles and water that will damage your wall cavities. This will eventually result in minimizing energy bills for your project and will keep your budget in balance.

There is two main resistance when it comes to a house wrap:

a. Air Resistance

Air resistance of a house wrap is its strength against the wind, stopping outside air from getting in and inside air from getting out. House wraps that have a significant level of air resistance help decrease your bills, and oppose soggy air from streaming into the pits.

b. Water resistance

House wrap water resistance is important because t makes it to be water-impenetrable to shield your home from water that gets behind the siding or cladding. In case water gets into the divider gap and can’t escape, it can create and cause shape or ruin. Less water resistivity of your house wrap can make it less feasible and decrease the essentialness capability of your home.

Both house wraps have good resistance against weather, water, and air but it is unpredictable which one has greater resistivity as it completely depends on the structure, climate, and the proper installation of your house wrap.

Tyvek house wrap claims to bear temperature that falls under -70°C to +118°C. But again, it completely depends on your area climate.

6. Durability

The durability of any house wrap depends on all the factors we discussed but the main factor that calculates the durability of a house wrap is its tear resistance. What is tear resistance? Tear resistance of a house wrap is its strength against strong winds and makes it hard to get ripped.

Many things can easily break or tear a house wrap including harsh weather, winds, bulky rainwater, and many other issues that can happen at your construction site. A house wrap needs to have a higher tear resistance to ensure the best functionality against heavy winds and water.

A higher tear resistance also keeps a house wrap in place after it’s installation thus making certain that water will not penetrate through your building from any spot. It is important to know about the tear resistance of both house wraps as it will have a major impact on the durability of your house wrap.

While comparing to Tyvek house wrap, Typar house wrap has nearly four times greater strength of about (ASTM D1117).

7. Cost

Being familiar with the prices of both house wraps are also important while selecting one of them because a house wrap should meet your budget requirement. Both houses wrap prices vary depending on the brands and areas where you are residing.

Always calculate your budget by 7% more than what you are expecting. This will save you from future worries and getting surprised by an excessive amount.

Prices of a Typar and Tyvek house wrap are the same and vary between $110.00 – $160.00. Installing a typar or a tyvek house wrap can cost you up to $800 starting from $250 depending on the Typar and Tyvek house wrap you buy. The average cost per square foot ranges from $0.41 to $0.97 for both house wraps.


Always make the best choice while choosing the house wrap. Form our comparison of Typar vs. Tyvek, you can now have a pretty clear understanding of both.

We will suggest you go with what suits you best but the main points to keep in mind is that typer wraps have very weak perm rating and they don’t have a drainage plane. But If you prefer surfactant resistance material with a high UV rating, then go with typar house wrap.

We hope that you gained enough information from this comparison and now have a clear idea of which one to use!
