Better Ventilation

Casement units open outward, which allows for improved ventilation and airflow compared to more traditional options like sliding sash windows. This design also maximises the amount of natural light entering the room, enhancing the overall ambience of your property.

Excellent Energy Performance

Casement windows can be more energy-efficient than other types of windows because they seal tightly when closed, reducing air leakage. This tight seal helps provide better insulation and minimise heat loss, contributing to lower energy bills.

Enhanced Security

Casement uPVC windows are very robust. With durable multi point locking system hardware and a high quality construction, these windows are built to withstand forced entry attempts.

Easy to Operate

Casement units are easy to operate for any homeowner or guest. They open and close effortlessly each time, thanks to their modern mechanisms.

Versatile Design

uPVC casement windows come in a variety of finishes and designs, allowing you to choose the perfect look for your house. Whether you prefer a contemporary or traditional aesthetic, there is a design to complement your property’s existing décor.

By choosing casement windows, you are investing in a premium, durable solution that enhances your house’s natural light and security.

Compatible with Triple & Double Glazing

When considering glass options for casement windows, it’s essential to understand the benefits and features of both double glazing and triple glazing.

Double glazing involves using two panes of glass with a layer of gas or air between them, significantly improving thermal insulation compared to single-pane windows. This double glazed glass helps in reducing heat loss, lowering energy bills, and enhancing the overall comfort of your house. For casement windows installation, opting for double glazed uPVC windows can be a smart choice due to their balance of performance and cost.

Triple glazing takes insulation to the next level by incorporating three panes of glass and two insulating layers of gas or air. This configuration provides superior energy performance, reducing the U value – a measure of heat transfer – even further than double glazed windows. When discussing installation with casement window suppliers, it’s important to consider if triple glazed aligns with your energy goals and budget.

Frequently Asked Questions

Explore our answers to some of the most common questions about uPVC casement windows.

Casement units are windows that open outward, usually with a crank mechanism. They are hinged either on the left or right side and are often used as a replacement for traditional sliding windows. These windows can be side-hung, opening like a door, or top-hung, with the hinges at the top of the unit.

Another similar style is flush casement windows, where the glass is level or “flush” within the window frame.  A standard casement window’s moveable parts stand out.

Our casement units are made from robust uPVC. This material is known for its durability, increased security, energy efficiency, and its sleek appearance. uPVC has become a popular choice among homeowners as they stand up well against inclement weather and do not warp, rust or rot like more traditional materials do. Compared to other materials like aluminium and timber, uPVC tends to be more aesthetically pleasing and boasts better thermal performance.

Cleaning and maintaining casement units is relatively easy. Simply wipe them down with a soft cloth and mild soap and water as needed. This method ensures there is no damage done to the uPVC window frames or mechanisms.

Yes, casement units can be very energy-efficient if they are installed correctly and made from high-quality materials. Look for windows with low-E coatings, double-paned glass, and insulated frames to maximise energy efficiency and meet the latest building regulations.

The lifespan of casement units depends on several factors, including the quality of the materials, the installation process, and how well they are maintained. In general, high-quality casement windows can last anywhere from 20 to 30 years or more.
