Contract uPVC Lipped Casement Windows
Lipped casement windows, also known as stormproof windows, are a popular choice for homeowners seeking a blend of traditional aesthetics and modern performance. Unlike flush casement windows, where the sash sits level with the frame, lipped casement windows feature a sash that slightly overlaps the frame, providing enhanced protection against the elements.
Fenea uPVC lipped casement windows provide an ideal solution for those seeking a combination of classic design, energy efficiency, security, and low maintenance. With advanced profiles like Liniar’s 70mm systems, homeowners can enjoy the benefits of modern window technology without compromising on style.
Superior Lipped Casement uPVC Windows
Fenea uPVC windows are manufactured using industry-leading profiles from Eurocell, Liniar and Rehau designed for superior thermal efficiency, security, and low maintenance.
Key features of our uPVC lipped casement windows include:
- Design & Aesthetics: The distinctive overlapping sash of lipped casement windows offers a classic appearance that complements various architectural styles. This design not only adds character to a property but also serves a functional purpose by improving weather resistance.
- Energy Efficiency: Our lipped casement windows are constructed using multi-chambered profiles, designed to provide exceptional thermal performance. The Liniar EnergyPlus range, for instance, incorporates a six-chambered profile that achieves unparalleled energy efficiency, allowing for cost-effective double glazing solutions. We can achieve U-values as low as 1.2 W/m2k (whole window), providing Part L compliance.
- Security Features: Security is paramount in window design. Fenea uPVC lipped casement windows are compatible with high-security locking mechanisms, offering homeowners peace of mind. The robust uPVC frames and secure hardware options ensure that these windows meet the Secured by Design standard.
- Low Maintenance: Crafted from high-quality uPVC, our lipped casement windows require minimal upkeep. Unlike traditional timber frames, they won’t warp, rot, or need regular painting. A simple wipe with soapy water is all that’s needed to keep them looking pristine.

Key Features Of Fenea Lipped Casement Windows
uPVC flush casement windows provide the aesthetic of pre-1932 timber windows but in a durable, energy-efficient material. This type of window is ideal where the style is required to suit the property or to comply with planning and conservation area requirements. A foil finish can be applied to mimic the appearance of timber, whilst we can also offer a mechanical joint rather than standard welded jointing to further match the style of timber windows.
Exceptional Thermal Efficiency
Our 70mm casement system is built with a multi-chambered profile that significantly reduces heat loss. Designed to achieve high energy ratings with cost-effective double glazing, these windows help lower heating bills and maintain a comfortable indoor temperature all year round with U-values as low as 1.2W/m2k.
Superior Weather Protection
The distinctive lipped design – where the sash overlaps the frame – offers enhanced protection against wind, rain, and draughts. This makes Fenea lipped casement windows ideal for exposed or weather-prone areas.
Slim Sightlines & Aesthetic Appeal
These windows offer slim sightlines without compromising on weatherproofing. The clean, sculptured finish adds timeless character to both traditional and contemporary homes.
Built-In Security
Designed with safety in mind, Fenea uPVC casement windows support high-security locking systems and feature internal glazing beads to prevent glass removal from the outside. They are PAS24 certified when specified with the correct hardware.
100% Lead-Free & Eco-Friendly
All the uPVC profiles used by Fenea are 100% lead-free and fully recyclable. Manufactured in the UK with sustainability at the forefront, Fenea windows are an environmentally conscious choice for any project.
Wide Range of Finishes & Styles
Available in a variety of colours, woodgrain finishes, and glazing styles, Fenea uPVC lipped casement windows can be fully customised to match your project’s requirements and planning stipulations.
Remember that Fenea can help ensure compliance with all aspects of your project specification:
- Part L: If the frame or window type cannot achieve the required U-value of 1.2W/m2k with double glazing, we can supply triple glazing down to 0.8W/m2k.
- PAS24 & Secured by Design: All our uPVC lipped casement windows can meet these standards as required.
- Part Q compliance.
- Acoustic glazing: We’ll ensure the glass specification meets your acoustic glazing report at the lowest cost.
- Part F: We’ll help you choose the best option aesthetically and to meet any planning requirements.
