Crown Molding Types
The material of installing crown molding: The crown rail molding are manufactured of the following materials :
Plaster: Plaster crown moldings are usually for plaster walls. It can be cast into complex profiles that can’t be crushed out of wood. Installing plaster crown molding can be quite costly and needs more care as they are made up of very heavy material and cracks very easily.
Solid Wood: Solid wood crown moldings are available in many simple stock profiles and can be used for any installations. Natural wood is a conventional material that is hard to reproduce; it’s color and grade patterns add warmth to the room. The drawback of installing crown molding of solid wood is that there is a chance of shrinking and swelling with changes in the weather.
Flex: Flex is a rubbery material that comes in an array of profiles that can bend around a curved wall without the need for relief cuts while installing crown molding. Installing crown molding of flex is quite costly and special order is required for its installation.
PVC: This type of crown molding is good for exteriors, bathrooms and the areas where moisture is a matter of concern. The plastic polymers of this product do not get damaged when there lots of moisture. The slick surface of the PVC crown molding is difficult to paint neatly but its paint is required to cover the plastic sheen in the area of installation.
Polyurethane: Polyurethane crown molding is one of the less expensive materials, they are more stable, rot and insect repellent than wood. While installing crown molding of polyurethane keeps in mind that it is slightly softer than wood, it is good only for painted applications as it dents very easily.
MDF: It is a low-cost alternative to solid wood and is more stable. Medium density fiberboard crown molding leads to cutting and posing the same challenges of solid wood.
The use of crowns started off in the Greek period itself. There were several changes made in the usage of crowns from that period, which was around 2500 years back. The primary change is with the materials. In the earlier case, the heavy stones were used. But now more lightweight materials are considered. These materials are malleable and in some cases, wood is also used. While many people prefer to go with these options there are many others who choose to go for their own materials. The moldings might sometimes be taken from foam and from flexible polyurethane.
