Want to find out more about our energy efficient window and door ranges?

uPVC casement windows are a type of window style known for their quality and modern functionality. Our windows are designed with a multi-point locking system that works with Kubu, providing enhanced security for homes. The term “uPVC” stands for unplasticized polyvinyl chloride, a durable and low-maintenance material used for constructing window frames. uPVC casement windows are equipped with double-glazed or triple-glazed glass, which not only adds to their security but also helps in reducing heat loss, making them energy-efficient.

There are several advantages to choosing uPVC casement windows. First and foremost, their multi-point locking system ensures superior security. Along with this, the double-glazed uPVC construction is not only energy-efficient but also helps in reducing heat loss, contributing to energy savings.

uPVC casement windows come in various styles, allowing you to offer your customers a wide range of options to suit their specific preferences and project needs. With their durability and modern design, these windows are an excellent choice for any type of window opening and are sure to enhance the overall look of any home.

Casement windows are designed to provide a high-quality solution for generous fresh air and natural light, as they can be easily opened to allow for proper ventilation.

As a trade customer looking for the right uPVC window manufacturer for your business, a few key considerations should guide your decision process.

The ability to offer a variety of options allows you to meet the specific needs and preferences of your customers.

Along with the variety of products, evaluate the manufacturer’s production capacity and efficiency. Reliable manufacturers should demonstrate the capability to handle bulk orders promptly and maintain consistent quality across large quantities. Ask about lead times for bulk purchases and whether there is flexibility to accommodate urgent orders, aligning with the often time-sensitive nature of trade projects.

Explore the manufacturer’s commitment to quality control and compliance with industry standards. You can request information on certifications and product testing procedures to ensure that the uPVC windows meet or exceed regulatory requirements. A manufacturer such as Emplas with a robust quality assurance process will deliver reliable and durable products.
