Here are some key features and benefits of these windows:
1.Energy Efficiency: UPVC is known for its excellent thermal insulation properties. Casement windows, when properly sealed, help in minimizing heat loss during the colder months and preventing heat gain in warmer weather. This can contribute to energy efficiency and cost savings on heating and cooling bills.
2. Low Maintenance: Resistant to rot, corrosion and fading. Low maintenance and do not require regular painting or sealing. They can be easily cleaned
3. Durability: A highly durable material that is resistant to various environmental factors, including weather, pollution, and insects. These windows are known for their longevity and ability to withstand the elements.
4. Security: Casement windows often come with multiple locking points, enhancing security. The design makes it challenging for intruders to force the window open from the outside.
5. Aesthetic Options: Available in a variety of styles and finishes. Our Ranges of Rehau & Linier Casement windows are available in both a Chamfered / Bevelled Design or in Fully Sculptured.
6. Choose from different colours, wood-grain finishes, and hardware options to match the aesthetics of your property.
7. Ventilation: Casement windows provide excellent ventilation as they can be fully opened, allowing fresh air to circulate into the room. Please remember due to current building regulations 99% of all replacement windows will need to be fitted with Trickle vents / ventilation (unless you have another form of mechanical ventilation, approved under Building Regs).
8. Sound Insulation: UPVC windows offer good sound insulation, helping to reduce external noise, creating a quieter and more comfortable indoor environment.
9. Customization: Casement windows can be customized to fit specific size requirements and design preferences. This allows for flexibility in choosing the right windows for different architectural styles.
