Known for its strength and ease of use, duropolymer coving is a lightweight alternative to traditional plaster coving, offering a similar aesthetic with less hassle during installation.
While Keaney’s specialises in plaster mouldings, duropolymer coving could be a more affordable option for those prioritising ease of installation and cost-effectiveness.
Overview of Duropolymer Material
Duropolymer is a polystyrene-based material, specifically designed to be both lightweight and durable. This material is high-density, meaning it can withstand significant impact without cracking or breaking like standard polystyrene. It's also shockproof, water-resistant, and environmentally friendly due to its recyclability. These properties make duropolymer an excellent choice for coving in environments where moisture or wear-and-tear could be an issue. Despite being a synthetic material, it can closely mimic the look of plaster or wood when installed and finished properly.
How Duropolymer Coving is Made
The manufacturing process of duropolymer coving involves compressing polystyrene into moulds to create various profiles and designs. The high-density polystyrene is processed under controlled conditions to ensure consistent quality and strength. After the moulding process, the coving is smoothed and prepared for installation. The result is a durable yet lightweight product that has well-defined edges, much like traditional plaster mouldings, but without the weight and fragility.
Benefits of Duropolymer Coving
Strength and Durability
Duropolymer cornice is remarkably durable despite its lightweight nature. It can withstand knocks, bumps, and general wear and tear far better than many other synthetic materials. This makes it particularly suitable for busy areas or spaces where there is a higher risk of impact damage. While not as robust as plaster, it is far more resistant to cracking than other materials, making it a good option for projects where longevity on a budget is important.
Lightweight and Easy Installation
One of the most attractive features of duropolymer coving is how easy it is to work with. Being lightweight, it is simple to cut, handle, and install, even in tricky areas such as high ceilings or curved walls. Unlike plaster coving, which often requires screws or additional support during installation due to its sturdy materials, duropolymer can typically be installed using adhesive alone. This makes the installation process faster, more cost-effective, and suitable for DIY projects.
Water and Impact Resistance
Duropolymer is water-resistant, which means it can be installed in areas with higher moisture levels, such as kitchens, bathrooms, and even some exterior applications. This is an advantage over plaster coving, which can be damaged by moisture over time. Additionally, duropolymer is shockproof, making it ideal for busy environments where bumps and impacts are likely to occur.
Eco-Friendly and Recyclable
For those concerned about the environmental impact of their building materials, duropolymer is a more sustainable option. It is recyclable and contributes less to waste compared to some other synthetic materials. While not as eco-friendly as natural plaster, the long lifespan and recyclability of duropolymer can help moderate its environmental footprint.
Common Applications of Duropolymer Coving
Residential Interior Design
Within the home, duropolymer coving is often used to enhance the appearance of living rooms, bedrooms, and hallways. Its lightweight nature makes it easy to install in homes where plaster coving might be too heavy or complex. Duropolymer coving comes in a range of profiles, from simple coved mouldings to dental block patterns, allowing homeowners to choose a design that complements their décor.
If you’re looking for more intricate patterns, it is best to choose traditional plaster. This material can provide finer details, often found on plaster ceiling roses or ornate designs of cornice and coving.
Commercial and Industrial Uses
In commercial and industrial spaces, duropolymer coving offers a durable and low-maintenance solution for adding some architectural detail. Its water and impact resistance makes it suitable for high-traffic areas such as offices, retail spaces, and hotels. Additionally, the material's ease of installation makes it a cost-effective choice for large-scale projects where both time and budget are important factors.
Duropolymer Coving in Renovation Projects
Renovation projects often benefit from duropolymer coving due to its lightweight nature. It can be easily retrofitted into older buildings without the structural concerns that can come with heavier plaster coving. Flexible duropolymer coving options are also available, making it ideal for non-standard room shapes. This adaptability makes duropolymer a popular choice in restoration and refurbishment projects.
Comparing Duropolymer Coving to Other Materials
Duropolymer vs. Plaster Coving
Plaster coving is often seen as the gold standard in decorative mouldings due to its historical use and premium finish. Plaster is highly durable and can last for centuries when properly installed and maintained. It also allows for greater customisation and intricate designs, making it the ideal choice for period properties or projects that require a high level of detail.
However, plaster coving is heavier and more challenging to install. It requires skilled labour, which can increase installation costs and time. Duropolymer coving, while not as long-lasting as plaster, offers a lightweight, affordable alternative that is easier to install and maintain. If budget or ease of installation is a priority, duropolymer may be the better choice, though plaster remains the superior option for durability and authentic appearance.
Duropolymer vs. Polyurethane Coving
Polyurethane coving is another popular alternative to plaster. Like duropolymer, it is lightweight, durable, and moisture-resistant, making it suitable for a wide range of applications. However, duropolymer tends to be slightly more durable due to its higher density, particularly in commercial or high-traffic locations. Polyurethane may offer more flexibility in design options, but duropolymer coving generally provides better durability for the cost.
Duropolymer vs. MDF Coving
MDF (Medium-Density Fibreboard) coving is commonly used in budget-conscious projects. However, it lacks the durability and moisture resistance of duropolymer. MDF can warp or swell when exposed to moisture, making it less suitable for areas such as kitchens or bathrooms. Duropolymer, on the other hand, offers water resistance, making it a better choice for environments with fluctuating humidity levels. Additionally, duropolymer is easier to install due to its lighter weight and flexibility.
Considerations Before Choosing Duropolymer Coving
Cost and Budgeting
Duropolymer cornice is generally more affordable than plaster coving, making it an excellent option for budget-conscious projects. However, it is important to consider the long-term costs of maintenance and replacement. While duropolymer is durable, it doesn’t have the same longevity as plaster, which can last for centuries. If your project prioritises long-term durability over initial cost, plaster coving is the better investment.
Aesthetic Preferences
For those looking to recreate the authenticity of period properties, plaster coving offers a smoother and more refined finish. Plaster mouldings can also be handcrafted to create intricate, custom designs that are hard to replicate with duropolymer. However, if you're aiming for a clean, modern aesthetic, duropolymer coving can achieve a similar look without the higher cost or installation challenges.
Maintenance and Longevity
One of the key benefits of duropolymer coving is its low maintenance. It is resistant to water, shock, and general wear and tear, meaning it can maintain its appearance without the need for frequent upkeep. However, it's worth noting that duropolymer, while durable, does not have the same long-term longevity as plaster coving, which can last longer with proper care.
Conclusion
Is Duropolymer Coving the Right Choice for Your Project?
When it comes to choosing the right coving for your project, the decision often comes down to budget, visual preferences, and installation requirements. Duropolymer coving offers a practical, cost-effective alternative to plaster, providing many similar benefits with added ease of installation.
