Windows Leicester
Replacement windows designed around your home, your style and your budget.
Whether your home is a grand country residence, a Victorian townhouse or a modern semi, changing your windows can transform the look, comfort and performance of the property. Gemini supplies REHAU window options for reliable everyday replacement glazing.
Gemini Windows and Doors can help you choose window frames, glazing layouts and opening options that feel right for the age, shape and look of your home.
Window styles
Choose the window design that fits the room and the building.
Replacement windows should improve your home without making it feel like it belongs to somebody else. The right design depends on the property style, room layout and ventilation needs.
REHAU casement windows remain popular for Leicester homes because they are simple, secure and versatile. Bay and bow windows can add shape and light to living rooms.
Colour choice can be kept simple with white uPVC, or made warmer with wood grain finishes such as mahogany or golden oak.
Energy efficient windows
A-rated windows that help keep warmth inside your home.
Windows can account for a significant amount of heat loss from a building. If old frames are draughty, poorly sealed or fitted with dated glazing, your heating system has to work harder.
Gemini Windows and Doors supplies energy efficient REHAU replacement windows with modern glazing and multi-chamber uPVC profiles. Standard windows are A energy rated as standard.
Choosing better windows can help reduce wasted energy, improve room comfort, lower condensation and reduce outside noise.
Security and structure
Strong replacement windows with built-in security features.
Every window should look good, but it also needs to feel solid when you close it. Gemini Windows and Doors supplies impact resistant, multi-chamber PVCu profiles engineered for strength.
Secure locking, strong keeps, correctly fitted frames and robust glazing options all contribute to a safer home.
- Internally beaded options for added security.
- Central reversing claws designed to lock securely.
- Optional locking hooks for additional protection.
- Security glazing options using laminated glass where required.
- Secure locking systems with practical night vent facility.
- Optional cranked handles with push button release.
