Window sills are essential to any window installation, providing structural support and serving as a base for your window. Among the materials available for window sills, two popular options are uPVC (unplasticised polyvinyl chloride) and laminated window sills. While both materials have their merits, they differ in properties, aesthetic appeal, durability, and maintenance. This article will outline the key differences between uPVC and laminated window sills, helping you decide on your next window installation or replacement project.
uPVC Window Sills: uPVC, or unplasticised polyvinyl chloride, is a type of plastic that is highly durable and rigid. Unlike traditional PVC, uPVC does not contain plasticisers, which gives it greater structural integrity. uPVC is widely used in construction for windows, doors, and other building materials due to its excellent weather resistance, insulation properties, and low cost.
Laminated Window Sills: Laminated window sills are typically made by layering a thin decorative surface material over a core substrate, such as MDF (Medium-Density Fibreboard) or particleboard. The laminate is usually made from melamine resin or similar hard-wearing plastic, which gives the window sill a smooth finish that can mimic the appearance of wood, stone, or other materials. The lamination process allows for various styles and designs, offering more aesthetic flexibility.
uPVC Window Sills: uPVC window sills are usually white and offer a clean, modern appearance. However, they are also available in a limited range of colours and finishes, such as wood grain or other faux textures, which can give them a slightly more traditional or decorative appearance. That said, the design options for uPVC are more limited than laminated sills, especially for homeowners seeking highly customised or premium finishes.
Laminated Window Sills: One of the main advantages of laminated window sills is their design versatility. They are available in various colours, textures, and finishes, including options that replicate the look of high-end materials like marble, granite, or natural wood. This makes them an attractive option for those seeking to match their window sills with the interior design of their home, whether that involves sleek modern decor or rustic traditional settings. The laminate can also be finished in a gloss or matte look, offering further customisation options.
uPVC Window Sills: uPVC is renowned for its durability and longevity. It is resistant to rot, corrosion, and warping, making it ideal for windows and window sills exposed to harsh weather conditions. uPVC window sills are highly moisture resistant, preventing issues like mold, mildew, and swelling—common problems with wood-based products. However, while uPVC is durable, it can be more prone to scratches and discolouration, especially if exposed to prolonged UV radiation from sunlight.
Laminated Window Sills: Laminated window sills are also designed to be durable, but their performance depends mainly on the quality of the core material and the laminate finish. High-quality laminate surfaces can resist scratches, moisture, and general wear and tear. However, cheaper laminates or poorly sealed edges can be vulnerable to water damage, leading to warping or swelling, particularly in humid environments. Scratches can be more visible on laminated surfaces than on uPVC, and repair options for damaged laminates may be limited.
uPVC Window Sills: uPVC window sills are low-maintenance and easy to clean. A simple wipe with a damp cloth and a mild detergent will usually keep them looking fresh. They are resistant to staining, mold, and mildew, making them a practical choice for homeowners who want minimal upkeep. However, uPVC can yellow or fade slightly if exposed to direct sunlight for long periods, although UV-resistant coatings can mitigate this issue.
Laminated Window Sills: Laminated window sills are relatively easy to maintain but require more care than uPVC. They are more susceptible to scratches and damage from sharp objects, so cleaning should be done with non-abrasive materials. While laminates are moisture-resistant, excessive exposure to water—particularly around the edges can cause delamination or damage. Regular dusting and gentle cleaning will keep the surface looking good, but laminated sills may require more attention if used in high-traffic areas or homes with pets or young children.
uPVC Window Sills: One of the standout features of uPVC is its excellent moisture resistance. Since it’s made from plastic, it does not absorb water, making it ideal for areas exposed to moisture, such as kitchens, bathrooms, or outdoor spaces. uPVC window sills are highly recommended for climates with heavy rainfall or fluctuating humidity levels, as they remain unaffected by changes in temperature and moisture.
Laminated Window Sills: Laminated window sills, on the other hand, offer a reasonable level of moisture resistance but are more vulnerable to water damage than uPVC. The laminate is waterproof, but the core material (often MDF or particleboard) can absorb water if the surface or edges become compromised. Prolonged exposure to moisture can lead to warping, swelling, or delamination, so it’s important to ensure that laminated window sills are well-sealed, especially around the edges.
uPVC Window Sills: uPVC window sills are generally more affordable than laminated sills. This makes them popular for homeowners or builders looking for a cost-effective yet durable solution. The affordability of uPVC, combined with its low maintenance and long lifespan, offers excellent value for money, particularly in high-traffic areas or homes with larger windows.
Laminated Window Sills: The price of laminated window sills varies depending on the materials' quality and the design's complexity. While entry-level laminated sills may be comparable in cost to uPVC, premium laminated finishes, especially those mimicking high-end materials like marble or wood, can be more expensive. The customisation options in laminates often come at a higher price, but they may be worth it for homeowners seeking a more decorative or tailored aesthetic.
uPVC Window Sills: uPVC is made from plastic, and while modern manufacturing processes increasingly use recycled materials, it is still less eco-friendly than wood-based or fully recyclable materials. However, uPVC window sills have a long lifespan, which reduces the need for replacements, and many manufacturers are focusing on increasing the use of recycled uPVC in their products.
Laminated Window Sills: Laminated window sills often use wood-based cores like MDF, which may come from sustainably managed forests. However, the laminate itself is typically a synthetic material made from plastic or resin, which can pose environmental concerns. While the environmental footprint of laminated sills depends on the materials used and the manufacturing process, many manufacturers are moving towards more sustainable practices, such as using recycled wood cores or eco-friendly adhesives.
Choosing between uPVC and laminated window sills largely depends on your specific needs and preferences. uPVC offers excellent moisture resistance, durability, and low maintenance at a more affordable price point, making it ideal for high traffic and moisture-prone areas. On the other hand, laminated window sills provide greater aesthetic versatility and customisation options, allowing you to match them with various interior design styles. However, they may require more care, particularly in environments where moisture is a concern. Both materials have their advantages, so the choice will come down to balancing practicality with design preferences for your home.

“Very impressed this time around!!! (disappointed with communication and delivery in first lockdown) and left a negative review which I updated after delivery. I can now understand all the good reviews before the pandemic. Still the cheapest by far and the products are spot on. I've just placed another order - Thank you keep up the good work” Jason Wright |
