Mouldex Exterior Mouldings is a nationally recognized supplier of architectural foam mouldings. Their stucco mouldings are used on many projects Canada wide, both residential and commercial.

Exterior mouldings for stucco and EIFS construction are made from, you guessed it, foam also known as EPS (Expanded Polystyrene).

Don’t let the word foam fool or scare you. Architectural foam mouldings are an economical alternative to wood, plastic and concrete for fabricating window and door trim, sills and cornices to name a few. You couldn’t get decorative details so affordably without foam. The cost is only dollars per linear foot depending on the size. They range from as small as 2″ to as large as 4′.

It is lightweight, moisture-resistant and suitable for exterior use because they are coated with cement. Our mouldings are always coated with two layers but certain applications can call for only one.

Below is an illustration on how an exterior moulding is produced.

For an in-depth look at how we produce our mouldings, we were recently featured on The Discovery Channel’s How It’s Made, here is our 5 minute segment.

And believe it or not, it is considered to be a green product. Have you ever thought of the implications of using trees in construction?

You can virtually have any shape imaginable. If you can draw it, it can be made although we have over 100 stock shapes that you can pick right off the shelf.

Buying mouldings can be overwhelming and it is best to consult with your stucco contractor or directly with us for advice. And once you have made your selections, we can create a 3D rendering of your home so you can visualize what it will look like once it’s complete.

Here are some general guidelines to follow when choosing exterior mouldings.

Start with your door and window trim and window sills…

And then work your way out. If your home is like most, your windows and doors occupy much real estate on your walls. It would be wise to set the style here and then incorporate the other elements like crown mouldings or wall bands.

We first suggest you determine whether you prefer predominantly round profiles or square. If you’re unsure, consider this. Round profiles project a softer tone while square can be the opposite. It is normal to match rounded trim with rounded sills but you can create some visually interesting effects by mixing the two. For example, match a round trim with a square sill or the other way around.

If your home and budget allows, think about adding;

Crown Moulding
Placed on the very top of your home, the majority of time under your soffits. It serves to hide the normally-bland inner corners of your home.

Wall Band
Wall bands can serve mutiple purposes. Most of the time, they’re used on areas of your home where two different materials like brick and stucco meet. They provide an transition between the two. They can also be used to hide expansion joints.

Pilasters can also serve multiple purposes. They can be installed on the vertical portions of window and doors, accompanied by a header over top. But our favourite is seeing them dress up corners in lieu of corner quions. Quoins are great, but very common.

Corner Quoins
Strictly for corners, they come in two main styles, single and stacked (one quoin placed on top of another in 8′ heights). As mentioned above, quoins have become a commonplace but people love them.

EIFS Columns are not structural by any means but the best way to describe them would be as wraps. If you have 4×4 metal or wood beams, surround them with columns. Standard sizes are 8″, 10″ and 12″ but can be made larger upon request with any moulding manufacturer.

In the ancient times, keystones were used to support arched structures. Today, in our application, they’re used strictly as a decorative element. Keystones are very inexpensive making them a great way to create focal points in your design.

This chart was created to maximize curb appeal. There’s no bigger mistake than having a small moulding on a large house and vice versa. Curb appeal is about being noticed for the right reasons.



Choosing the colour of your mouldings will likely be the last in the decision process and will greatly affect the look of your home. Most contractors and homeowners will agree to stay within a few shades of the wall colour.

If you’re looking for something bold, consider going darker than your walls. This will clearly define the separation between your mouldings and walls and give your home extra punch.

If subtle is more your preference, knock it down a few shades. This will leave your home in a state of harmony which is elegant if done correctly.

If you’re not sure if a bold or subtle look will suit your home, drive around your neighbourhood for inspiration. Notice the difference between the two styles and you’ll quickly realise which one is best for you and your home.

Regardless of what you decide, make sure to request colour samples from your stucco contractor and compare it against your wall colour.
