Protect Your Thermally Modified Siding From Warping

Protect Your Thermally Modified Siding From Warping

Thermally modified Siding and rainscreen panels are used more frequently in modern construction. They are affordable, durable, and easy to install. But what should you do to protect your siding and rainscreen from warping?

Make Sure You Shingled Your Rainscreen Correctly

If your siding and rainscreen are not shingled correctly, it can cause extra pressure on the panel. Since the sheathing is put on first, the siding is drawn into the gap in between. This can leave you with a warped board that could warp further from moisture damage or heavy winds.

Build a Flashing Over the Butt Joints

You should build a flashing at the butt joints of shingling and install it over the butt joint of your siding and rainscreen panel. This will help reduce stress on your siding because it is attached to another piece of siding.

Install a Horizontal Eave Flashing

You should also install a horizontal eave flashing for weatherproofing to ensure no moisture buildup behind your thermally modified siding and rainscreen. If you have extra wide panels, you may want to use a Z-flashing to keep more water out from between your boards and prevent warping, especially if you live in an area with heavy rains or snowfall.

Install a Rain Cap

You should also install a rain cap to keep water out of the gutters. This will be weathertight and prevent any water that accumulates on your panels from leaking into your home. A rain cap and flashing measures for your rain gutter can help prevent the siding from warping and keep it in good condition.

Use High-Quality Siding Material

High-quality siding and rainscreen material are also essential to help prevent warping. You can find thermally modified siding made with polyurethane, which will be much more resistant to moisture and weather. Polyurethane is also more durable and will not break down.

Use Proper Sanding

Using proper sanding techniques will also help a lot. For the first coat of paint, you should use 120-grit sandpaper to eliminate any uneven patches and bumps on your siding. Then you should use an 80 grit to smooth out the entire surface. Once you have leveled it out and gotten rid of all the bumps and uneven patches, you can move on with the next coating.

Install a Good Water Shielding System

Once you have installed your siding and rainscreen, it is essential to install a good water shielding system for the gutters and downspouts, so water doesn’t leak through your siding or rainscreen. This will help keep moisture away from your panels and prevent warping.

Use Shingles That Have Backing

Shingles are used with exterior siding and rainscreen to help add extra protection and weatherproofing, especially if you need to go over a gap. The best type of shingle for this is one that has backing on it, as it will keep water out of your gutter or downspout and decrease the chance of leakage into your home.
