A cornice is a kind of decorative construction material which is installed along the seam where the wall and the ceiling are combined. It is usually applied in the following four kinds of situations:

1) Use cornices when the house is not high enough for a complex ceiling design.

2) When the materials or colors of the wall and ceiling are different, there will be a clear borderline. And in order to cover this boundary, many people will install cornices in a similar style.

3) Apply cornice to retouch some of the flaws. For instance, when the wall is not flat because of inaccurate measurement, or when a curved line found at the junction of the ceiling and wall, then cornice works.

4) When parts of water pipes or electric wires are paved in the ceiling, cornices can cover them to some extent.

Due to the different materials, the appearance, texture, price of cornices will be different accordingly. Plaster cornice was the most popular option in the past, while now it’s time for Polyurethane Cornice, a relatively newer material for ceiling cornice. Why it becomes the best choice? Follow me and I will show you how PU cornice stands out from them.

1. Common traditional ceiling cornices

Plaster Cornice

Based on plaster powder, plaster cornice is considered as the most common and versatile type of cornice. It is cheap and exquisite with sound insulation and heat insulation functions.

Though popular it is, the installation of plaster cornice usually needs to be operated by professional workers. And there is glass fiber inside, resulting in a low safety performance. Besides, plaster ceiling cornice is heavy and easy to break during transportation. Most importantly, with poor moisture resistance, once the air humidity is high for a long time, plaster cornice is prone to yellowing and deforming. So plaster cornice may not be a good option in humid areas.

Wood Cornice

Wood ceiling cornice is often applied in Chinese style and European classical style decoration. It is a high-end and friendly-environmental option. Wood cornice is mainly made of solid wood, which is a complex process and requires much attention to details so that the price is relatively higher than plaster cornice.

Same as plaster cornice, wood is not waterproof itself. So if the waterproofing arrangement is not done perfectly, wood cornice may have obvious cracking, deformation or paint drop. Furthermore, solid wood fears moth and is difficult to maintain, thus making it a choice of the few.

Plastic Cornice

Plastic cornice that made of PS (polystyrene) or PVC (polyvinyl chloride) is the cheapest solution for those who have a limited budget. It is also a popular choice that features low cost and low weight. However, it is not a good option because it will look a bit cheap and you’ll see the obvious joints.

2. What’s Polyurethane Cornice and Why choose it?

PU, which stands for Polyurethane, is a new material for cornice. It is no exaggeration to say that polyurethane cornice has all the advantages of the other types of cornices while avoiding all their disadvantages meanwhile.

PU cornice is a foam cornice which is light enough to be conveniently installed by only one person, thus saving installation, use and maintenance costs. For the same volume of ceiling cornice, the workload of PU cornice is only 1/3 to 1/5 of that of solid wood and plaster and PU can save nearly 80% construction costs.

Though thin and light it is, it is still beautiful and exquisite and has a strong stereoscopic effect. The surface can be painted in various colors of water paint and oil paint which can last for a long time. Moreover, it can vividly imitate stone, wood and metal. Whichever style you like, PU Cornice can meet your preference.

Since Polyurethane is a polymer material that is molded at a high temperature, it can bear a temperature from -20℃ to 120℃. And it is stable and durable enough to resist deformation, crack, yellowing and corrosion. It is also waterproof and can even be directly washed. Last but not least, it is environmentally friendly with no emissions.
