7 Reasons to Use Styrofoam Crown Molding

When we think of crown molding, most people only think of the traditional wood option. Wood is the most well-known material for crown molding, and many homeowners are unaware of other alternatives. With the cost of wood escalating, more people are turning to alternate materials for their home DIY projects.

1. Price

Lumber in today’s market can be quite expensive. There is also a shortage of supplies in some places with a long waiting list, driving up both price and demand. Since the cost of lumber is on the rise, this affects wood crown molding as well.

Traditional crown molding is made of wood, which means that it may cost more than Styrofoam crown molding, which tends to be 28% cheaper.

2. Weight

Wood has quite a bit of weight to it. If you have high ceilings, you may find it challenging to hoist the crown molding up your ladder to install it. It may also pose a safety concern. Styrofoam crown molding, on the other hand, is lightweight. You will be able to carry it without issue.

3. Quality

Wood crown molding can change and warp when exposed to humidity, moisture, or extreme heat. Wood will expand in times of high humidity, leading to shrinking or gaps. If you have an older home, there may be issues with the foundation shifting, which also affects the crown molding.

Styrofoam is easy to install even if there are uneven spots or other issues that need concealing. It is durable when installed in areas of high humidity like a bathroom.

You can be very creative and dress up the look by adding ceiling medallions, window and door trim, trim for wainscoting and chair rails, or finishing on cabinets. It allows you to generate additional style while being cost-effective.

4. Pliable

Styrofoam is easier to bend and shape. However, it can also be more fragile. If your room has any curves or you have a unique project, Styrofoam will be less of a hassle and easier to manage. Wood, on the other hand, is not as pliable and won’t allow you to bend it if necessary.

5. Installation
