Is Your Vinyl Siding Melting? Find Out The Cause And The Solution

Is Your Vinyl Siding Melting? Find Out The Cause And The Solution

Why is my vinyl siding warping?

It’s happening to homes across North America and homeowner’s are scrambling to fix their siding only to see it warp again.

It’s a relatively new phenomenon and while the vinyl siding might seem to warp out of the blue, it’s actually being caused by the sun reflecting off of windows that are coated with Low-E film. 

Low-E film is a reflective coating that’s applied to windows so they can reflect heat and make homes more energy efficient. 

However, under the right conditions the sun can bounce off the Low-E window and concentrate into a powerful beam that can reach temperatures well over 200° F.

So, most of the time when vinyl siding melts or warps it’s because that’s where a beam from a Low-E window has landed.

The reason why the siding warps is not because it’s a defective product. It was just never intended to be exposed to temperatures that high, as most vinyl siding will melt at just 165° F. 

Just one Low-E glass window can easily cause thousands of dollars in damage.

Most people don’t even realize what’s happening or why, they just see that large patches of siding have been warped or turf has been scorched.

This is a relatively new problem and it’s rapidly growing every year because most new homes are being built with Low-E windows.

Melted siding has now become so widespread that the major vinyl siding manufacturers have updated their warranties to exclude damage from heat caused by window reflections.

Making things even more complicated is that a lot of the time it’s a neighbor’s Low-E window that is causing the damage.

So if this is happening to you of your neighbor, do not replace any damaged siding or turf yet.

The window is the source of the heat beam, so that needs to be addressed first.

If you replace your siding or your turf without first fixing the window, you’ll just end up having to replace the same things again and again.

What’s the best way to stop my siding from melting?

The window is the problem, specifically the way the sun is reflecting off the Low-E coating.

Replacing the window may seem like the most obvious solution, but it’s not necessary. 

Getting a window replaced is costly, and most Low-E glass windows are relatively new, energy efficient and are otherwise in good working order. 

As long as you can block the sunlight from hitting the window in the first place, you can stop the heat beam from forming.

Do not install a product between the vinyl siding and the window as a means of protecting the house.

Anything that is in the path of the heat beam will get damaged, so installing something like a fence or umbrella would just mean constantly replacing something else instead of siding.

The key is to keep direct sunlight off the Low-E window.

Some people have put awnings over their windows as a way to block the sun from hitting them.

This solution can work because it blocks the sun from directly hitting the glass, but it does have some drawbacks. 

It’s one of the more expensive options, and awnings require a lot of maintenance.

They can easily get damaged by wind if they are left extended, so they can really only be used so long as you are home.

Retracting your awning every time you leave the house may mean that the sun can still hit your Low-E window and form hot spots.

So even with an awning you could still run into the same melted siding problems.

Planting some strategic trees as a means of shade would work, but again it’s not a practical solution.

It’s expensive and not everyone has the available space to be able to plant a large shade tree or trees.

Replacing melted siding with a heat resistant type of siding is an option, but it’s by far the most costly as it would mean having to replace the siding for the entire house.

The easiest and cheapest solution is to cover the window that’s causing the damage.

Painting over the outside of the window is cheap and easy and provides an immediate fix to the problem.

However, the entire point to having a window in the first place is to get natural light into your space.

Installing EZ Snap shade mesh over the Low-E window is the best way to fix a window while still keeping natural light.

EZ Snap works by blocking 90 percent of the sun’s heat and light from ever reaching the glass.

What does reflect off the glass gets filtered a second time on it’s way back out, ensuring that no hot spots can form from any Low-E glass reflections. 

To see how well the shade mesh works in action, here’s a review a customer sent in who had a Low-E window that was melting siding. The video shows both the before and after of how EZ Snap stopped the hot spots from forming.

EZ Snap can be installed on almost any size and type of window. 

Because EZ Snap uses an optical grade mesh, you still get to keep your view as well.

It’s also easy enough to install that you don’t need any previous experience.

Is the vinyl siding on your house melting or warping?

A more common problem than homeowners realize. It is almost always caused by the sun reflecting off a nearby window onto your vinyl siding.

New low e windows act like a magnifying glass, concentrating the sun’s energy onto a small area. Temperatures in these hot spots often exceed the melting temperature of vinyl siding, causes thousands of dollars in damage.

Typically, most vinyl siding products will start to melt and warp when they reach 160 to 165 degrees Fahrenheit. On darker colored siding, temperatures have been recorded of nearly 220° F in the area where reflected light is hitting.

Is melted vinyl siding a new problem?

Melted siding from window reflection is a problem that has become more common in recent years. The main reason is the increasing number of Low-E or energy efficient windows that are being installed in new homes or renovated homes.

Low-E windows are designed to reflect more heat away from the glass by design.

That is why low e windows help cool your home. The problem is that reflected light off these windows is now more powerful than ever and it substantially increases the surface temperature of the objects it lands on, like vinyl siding or artificial turf.

Facts from vinylsiding.org:

Glass in double paned windows may on occasion slightly warp or deflect due to a difference in barometric pressure between the interior of the glass panes and the outside air pressure. This can create a concavity in the glass. Such a concavity is a normal response to pressure differences, does not affect the performance of the window, and does not constitute a defective window condition. However, the concavity may focus sunlight reflected from the window in a fashion similar to the effect seen when light passes through a magnifying glass. The heat generated by the focused reflected sunlight has proven sufficient to visibly damage and distort vinyl siding on nearby houses.

Any double paned window may cause this effect, but double paned low-e windows have a higher reflectivity quotient which can exacerbate the reflected light/vinyl distortion phenomenon…

A combination of contributing factors must be present before the effect occurs or causes damage to any nearby materials, including vinyl siding. The presence of the concavity in the double glass panes (resulting in the magnifying glass effect with a focused light beam) appears to be the primary cause of the heat generation, more so than the mere increased reflectivity of the low-e window.

The angle of the sun is also a factor. A low angle of sunlight (such as might occur in late fall, winter, or early spring) is more likely to produce the effect.

Other factors, such as proximity to the adjoining house, wind speed, air temperature, and the presence of buffering foliage are all said to have an impact on whether a damaging reflected sunlight effect does in fact occur.

Facts from The International Association of Certified Home Inspectors:

The intense reflection from low-E windows is reported to have caused other kinds of damage, as well, such as melted plastic trash bags and plastic garbage cans, melted plastic solar collectors, melted plastic parts of vehicles, and melted housewrap on new builds yet to be covered with siding.

Four house fires were confirmed to have been caused by such reflections, according to an investigation by the Consumer Product Safety Commission. In these cases, reflections from sunroom roof glass and skylights ignited nearby cedar shingles.

The hazard is not limited to property. One new high-rise hotel in Las Vegas reportedly gave off reflections hot enough to burn people using the hotel pool.

Windows with standard glass panes can cause similar damage in some situations, but this is rarely reported.

Top 3 Ways to Prevent Melted Vinyl Siding

The easiest and most effective way to stop reflecting sun rays from melting and warping your vinyl siding, is to block those rays.

There are a variety of ways to block reflections from windows. Depending on your situation, you most likely desire quick, easy and inexpensive options.  Here are three melted vinyl siding solutions:

1. EZ Snap™ Sunshade Mesh

Stops the Sun: Exterior window shades stop intense sun from passing through your windows and also stop reflection off the outside of the glass. You end up not only stopping the sun from melting the siding, but the exterior window shade also substantially cools the room with the window.

Easy & Quick Installation: A do-it-yourself exterior shade system like the EZ Snap exterior shades can be easily installed be someone with no previous experience.

Inexpensive: They are also very affordable, costing as little as $1.70 per square foot. If the offending window happens to be on your neighbour’s house, they are so affordable, you can offer to install the EZ Snap exterior shades for free for them. This saves them money on their air-conditioning bill and you instantly stop the sun from damaging your vinyl siding.

The solution to this problem is to stop the sun’s rays before they can hit the glass and reflect off of the glass surface. When you install the EZ Snap exterior shades on your windows, it is like planting an instant shade tree in front of the offending window.

EZ Snap stops up to 90% of the sun’s rays from reaching the glass. The remaining 10% that does get through is reflected back,  but must then pass through the EZ Snap mesh a second time. Again, reducing it a further 90%.

With 99% of the reflected light now eliminated, the problem of melted vinyl siding is also eliminated.

Added Sunshade Mesh Benefits:

  • Cools the interior of your home and surface of the glass.
  • Provides daytime privacy.
  • Reduces annoying glare inside and out.
  • Lowers your air conditioning bill.
  • Prevents birds from flying into the reflective glass surface.
  • Reduces the fading and damage caused by the suns U.V. rays.

2. Plant Trees

Although this is a natural and eco-friendly solution, planting trees and waiting for them to mature, obviously takes significant time and patience. Trees and other landscaping have potential to block reflection from windows, however, seasonal leaf loss and varying sun angles can result in poor results. There’s a good visual of different options around the 2 minute mark in this DIY video…

3. Replace Vinyl Siding with Hardy Plank

Like EZ Snap, replacing your vinyl siding with cement board product like Hardy Plank is a guaranteed fix. Unfortunately, replacing your siding is a time consuming and very expensive solution. A siding repair or re-install is also beyond the ability level of most do-it-yourselfers.

When replacing your vinyl siding with Hardy Board, in extreme cases, there’s still potential for the extreme heat to discolour or damage the painted surface of your new siding.
