LP siding wood shed
LP® siding gives wood sheds a deeply embossed cedar grain pattern that looks authentic and offers superior moisture resistance.

When buying a new wood shed, there are many things to consider. One of them is, “What kind of siding is best?” While sheds made with T1-11 are less expensive than sheds with LP® siding, will it actually save you money in the long run?

While this may not be the first thing you think of, but the type of siding your wood shed is constructed with is a major factor.

LP® manufactured wood siding is the best choice for wood sheds. Our LP® Smartside siding is weather resistant, does not need yearly staining or painting (once painted), rot, decay and insect resistant, and paint jobs are more durable with LP® Smartside siding.




Why Using T1-11 Siding on a Wood Shed is a Thing of the Past…

T1-11 wood sheds siding
T1-11 is a cheaper solution for a strong wood siding for a shed, but it will cost you more in the long run.

Wood sheds used to be made with T1-11 siding, also known as plywood.

While T1-11 siding is cheaper, it cannot stand up to the elements of mother nature as well as LP® wood siding and requires yearly maintenance. Even with regular maintenance plywood is extremely susceptible to water damage. Conversely, after painting, LP® siding requires very little maintenance.

 Advantages of LP® Smartside Siding

  • Rot, decay and insect resistant
  • Easy to paint and maintain
  • Attractive, natural look of wood
  • Very durable; Hardboard protective face on the surface
  • Outer coating of wood pulp, resin and linseed oil, leading to a near-moisture proof board.

Advantages of T1-11 (Plywood)

  • 100% Natural
  • Cheaper

Disadvantages of LP® Smartside Siding

  • Higher costs

Disadvantages of T1-11 (Plywood)

  • Require yearly maintenance
  • Prone to wicking water, which leads to rot
  • Poor painting properties. T1-11 is rough and paint doesn’t stick very well, which can lead to warping and peeling paint.
  • Professional maintenance recommended to keep wood at its best

Louisiana-Pacific Corporation, commonly known as “LP”, is an United States building materials manufacturer. Today, LP® is the world’s largest producer of OSB and manufactures engineered wood building products.

LP® Siding is the Best Choice for a Wood Shed

As you can see from my above pro and con list, LP® siding is the better choice for a wood shed unless you just happen to really, really love T1-11 siding.

These days, all the rage is over “natural” products. However, LP® Smartside siding is actually more natural than it may initially appear. It is still pure wood, but with an added layer of protection. It’s simply a product that has taken natural materials and processed them into a maintenance free wood.

If you’d prefer to have your maintenance done up front, then choose LP® siding.

If you prefer to maintain your wood shed, year after year, adding coats of paint, layers of primer and insect repellent, then choose plywood. In the end, they will both end up with the same amount of added layers. Plus, the expenses of maintaining the T1-11 siding will end up costing you more money!

As the old saying goes, “Work smart, not hard.” Smartside siding is the “smart” choice, so you don’t have to “work hard.

my 20 year old t1-11 shed shows minimal weathering /wear. I painted it when it was built and that is it.There is no rot ,warping ,or pealed boards.

Hi JP,
That is good to hear. It is possible to get good wear out of t1-11 wood siding, but it usually requires much more maintenance year after year. Some climates are worse than others as well. Thanks for visiting our blog!

Is this the siding that Duro shed uses & if so where can I purchase a piece?

Good Afternoon Roger,
I am not 100% sure on that. Not sure what type of siding Duro Shed uses. You can purchase LP siding at most home improvement stores such as Lowes or Home Depot.

Read this and went to Home Depot webpage. Their T1 11 plywood is more expensive than their LP product (+$10/panel). The LP is not as thick and when looking at it looks like pressed wood. What am I missing?
Tks. John

Will the LP Siding hold with nails as good as the T-111? Does it strengthen the building as mush as T-111?

Posted on January 1, 2016 at 3:20 pm

Posted by bdeitsch

Good Morning James,

LP siding is as strong or stronger than T-111. LP siding is an engineered panel product made of wood strands oriented for strength and exterior rated adhesives.”

LP siding is also a rated panel meaning it has testing behind certifying its use in residential construction. This translates into a very strong, rated panel for shed construction.
Nailing the panel in lace is the LP recommended installation method and will hold as good or better than T-111 when following the LP recommended fastener sizes and spacing.”

The south side of my house with T1-11 has

loads of peeling paint and some dry rot holes.
Two options:

I can scrape, sand and fill the 28′ of siding..
..Or I can I just put new T1-11 over the existing old T1-11? The rest of the 30 year old house is in good shape.

When installing the LP Primed Smartside siding on a shed, should it be installed using nails or screws? Where should you caulk?

Posted on August 4, 2016 at 4:55 pm

Posted by bdeitsch

Good Morning Jay,

Thank you for visiting our blog. That is an excellent question. Yes, you can install LP siding using nails and screws, but LP has certain recommendations based on the series of siding you have. I would highly recommend that you watch this Video – provided by LP! In terms of caulking, caulk anywhere you see daylight – such as seams and joints.

Feel free to give us a call at 855.853.8558 if you have any other questions. Have a great day!

Will the LP smartside deteriorate like the LP siding used on so many houses in the late 80’s if not carefully sealed on the bottom?

Posted on September 14, 2016 at 5:26 pm

Posted by bdeitsch

No, Lousiana Pacific is using a different compound of LP siding in new homes. However, we always recommend to seal all seams and joints. Basically, if you see light shining through a crack, you better fill it.

Can LP Smartisde be installed over open studs, or does it require additional sheathing underneath?

Posted on October 16, 2016 at 9:57 pm

Posted by bdeitsch

Good Morning,

Yes, LP SmartSide siding can be installed right over studs. That is actually how all of our sheds are built. Please let me know if you have any other questions!

Have a great day!

How about installing T1-11 over building wrap, over studs? Does the building wrap still function correctly? Trying to do an instulated addition on the cheap…w/ fiberglass batts

Posted on November 14, 2016 at 2:17 pm

Hello. I’m contemplating a residing of a concrete shed and am deciding between T1-11 and Smartside. I’m liking Smartside for all the reasons you point out, plus the fact that I find it is a lot cheaper at my local Home Depot than T1-11! I do have two questions though.

1. Does Smartside offer the same 8″ wide vertical design as T1-11?
2. I notice that Smartside is thinner. How might this affect durability and longevity?

Thank you!

Posted on December 1, 2016 at 4:58 am

Good Morning Jon,

Yes, LP Smartside panels come 8″OC. If you use the OSB strand product (Precision Series) it can be installed direct to studs 16″OC or you can use the fiber substrate (Foundation Series) but then you must use OSB sheathing underneath. Both require you to use a house wrap behind the panels. Both products have the same warranty. It just depends on what you want to use. I hope that helps! If you have any other questions, feel free to give us a call at 855.853.8558. Thanks for visiting our blog.

I have the old T 1 11 (from the 90’s) and have to paint it (can’t afford to replace.) To power wash, would you add something to the water? What kind of paint properties do you recommend?

Good Morning Bill,

Thank you for visiting our blog. We typically do not deal with customers putting LP siding over T1-11. I would reach out LP directly by visiting their website at LP Building Products

What about applying a Weatherguard instead of Paint?

Posted on June 13, 2018 at 1:21 pm

Posted by Brennan

We generally do not deal with Weatherguard, so can offer much advice here. Sorry about that.

We have a 20 year old T 1-11 garage that has rotten siding all around the bottom few inches. Is it practical to cut out the bottom foot of the siding and useing a Z strip replace it with LP siding and then paint it. Will the 8″ striations on the T111 match up with the LP Siding ok?

What this blog fails to point out is this. There are three completely different construction methods used to manufacture an exterior wood siding and yet, all three products are referred to and labeled as T1-11. Two of these T1-11 products are inferior to the all wood T1-11 product manufactured by Georgia Pacific.

See YouTube video “All T1-11 are not created equal.”

I built a 12’L x 8’W x 8’T three sided wood shed 16yrs ago in Spotsylvania, Virginia. I painted it once, that’s it. No rot, no peeling, no flaking. Still a very solid structure. If you buy T1-11, make sure it comprised entirely of wood.

Both the LP exterior siding and the all wood T1-11 are good products. Install correctly, seal and paint as you should and enjoy.

No, I do not work for, nor do I get any compensation for my comments or views about either product. Poor prep, poor installation and lack of maintenance can lead to the deterioration of any wood engineered product.

You may want to consider cutting up t111 , you may need to add some blocking on inside if open inside. Then slide a 3/4 ” drip cap up in place and
you can use pt boards as a mud sill or better what I used was a solid pvc board ,never touch it again.
