styrofoam crown molding?

Concerns are:

I never had any success cutting with anything other than my power miter saw(with an 80 tooth blade and slow speeds) or a hand coping saw. Used fine files for final shaping.

Stuff breaks very easily. Mandatory to have two installers minimum. Means two people to cut/carry/hold in place/nail. Three is even better.

Cutting to get good fits on corners. Cope cutting inside corners and miter cutting outside corners is the (IMHO) best method. Cutting foam is different from wood/MDF and requires a lot of attention.

Installing with nails. Hand nailing can create dents. Each nail should be started by hand and finished with a nail set. Very labor intensive. Nailing with an air nailer using too much pressure means a divot for each nail and the porbability the nail goes completely through the molding. But, any nail site will require putty. Smaller holes mean less/faster puttying.

Depending on the width of the crown, you might need a backer installed. Wood strip sized to be installed in the angle between wall and ceiling to support the crown and for nailing.

Foam crown is my third favorite, after painted wood and stained wood. Much better than MDF crown.

Close up of crown moulding
Still on the fence about installing crown moulding?  There are a number of reasons why adding a crown moulding feature can improve the look of your home.  Choosing plaster coated foam crown moulding is the smart choice over other types moulding for a number of reasons.  Here are a few:

1. Save Money

By far the biggest advantage of plaster coated foam crown moulding is that it is the least expensive form of crown moulding available.  Trimroc’s plaster coated foam crown moulding products are a better low-cost form of crown moulding while improving on durability and quality.  Additional savings can be achieved by installing it yourself.

2. Add Architectural Appeal

3. Increase Property Value

The home is often the biggest investment in any person’s entire life.  For the homeowner, keeping or increasing the property value of the home is of the utmost importance.  Incorporating a simple upgrade such as crown moulding can add as much as $10,000 to value of a home with a $2000 investment.  It is seen as a much desired upgrade and gives the home a feeling of increased value.

4. Easy to install and covers up messy DIY work

Plaster coated crown moulding is a great way to finish off a home renovation project.  It’s so lightweight and easy to install that any do-it-yourselfer can get it done in one weekend.  All it takes is some know-how with a miter saw and drywall compound.  It can be used to cover up a messy paint job where the ceiling and wall meet or cover up wavy or uneven existing drywall work due to its flexibility. Trimroc’s crown moulding comes with a smooth paintable plaster finish making it easy to customize further with whatever colour of paint would match the decor.

5. Hide speaker or electrical wires

Opening up a wall to run some speaker wires or electrical wires can be messy work.  Why not kill two birds with one stone and run the wiring behind the crown moulding and adding a nice architectural detail at the same time?

These are just some of the reasons to install plaster coated foam crown moulding.  Canamould has a huge selection of styles to choose from.  Get in touch with one of our specialists and we’ll help you find the perfect profile.

Crown molding styrofoam

NovaCrown moldings are so durable that when installed they will withstand the normal settling process as well as the transportation process of factory built homes from factory to site. This eliminates the need for costly and time-consuming touch-ups and repairs. Unlike MDF crown moludings, NovaCrown isn't affixed to the underlying framework of the structure so it isn't pulled and pushed as the structure is subjected to these various forms of movement. 

Moreover, NovaCrown mouldings are unaffected by changing temperatures and different climates so they never twist, warp, crack or rot even when installed in stable, factory environments then transported into extreme climates. 

When considering these benefits as well as its simplicity of installation and ability to streamline production lines, NovaCrown mouldings represent extraordinary cost savings that no other crown moulding can offer. 

If you are a home builder contact NovaCrown today to add incomparable efficiency to your business.

Foam Crown Molding

The Project

Our customer needed to create large, “built-up” crown molding that could be installed on the wall to be used as shelves. They did not want the weight of wood molding and had a limited budget. They contacted Universal to see about using expanded polystyrene (EPS) for the crown molding. EPS molding is sometimes mistakenly referred to as Styrofoam molding.

The Problem

EPS has texture, and even when coated with various hard coat products, the surface textures remain, although not quite as defined as the unfinished material. Other concerns the customer had were the strength of the material and how they would be able to install it on the wall.

The Solution

Universal Foam Products worked with the customer to finalize the design of the crown molding. The molding was wire cut from .9 lb Virgin EPS. The molding was then coated with ready mix drywall compound that was slightly watered down to create a consistency just thin enough that it could be brushed onto the EPS instead of needing to be troweled on. The compound was allowed to dry overnight and then sanded with both 150 and 220 grit fine sand paper to a perfectly smooth finish. The trim was then painted with one coat of latex semi-gloss paint. After the paint dried the crown molding was ready for installation.

A single strip of Incrediseal ¾” x 1/32” double stick foam construction tape placed across the center of the back of the trim. Two lines of “foam compatible” construction adhesive were applied above and below the tape to the back of the molding also. The trim was then pressed firmly to the wall. The purpose of the tape, in this application, is to hold the molding in place until the construction adhesive has time to set-up.

The finished product looks exactly like wood crown molding at a small fraction of the weight of wood.

Additional Benefits of EPS Architectural Moldings by Universal Foam

EPS is used for a variety of architectural moldings including crown molding, columns, capitals and bases, dental molding, balustrades, brackets and parapet caps. It can be finished smooth to look like painted wood or coated with a cementitious coating to look like concrete. Lightweight and easy to install, it is an excellent alternative to wood, plaster and concrete architectural shapes offering substantial cost savings as well.
