European Tilt and Turn Windows

European tilt-and-turn windows have seen a significant rise in popularity across Berkshire, Hampshire, Surrey, and the South East, offering homeowners a high-quality and elegant glazing solution for thermal efficiency, ventilation and security.

At Thames Valley Windows, we specialise in designing and installing European Tilt and Turn Windows from leading European brands, Internorm and Solarlux, renowned for their innovative, forward-thinking design, to offer energy-efficient, versatile, high-performance glazing options that combine sleek European aesthetics with exceptional durability and longevity.

European Tilt-and-Turn Windows are the standard in European homes. In this latest blog article, we look at the tilt-and-turn windows offer to UK homeowners.

What Are European Tilt-and-Turn Windows?

They open and close with a single handle that features a unique dual-opening mechanism, allowing the window to open inward from either the top or the side.

In tilt-open mode, turning the handle to 90 degrees, the top of the window tilts inward, providing secure, controlled ventilation —ideal for bedrooms and living spaces.

In open inward mode, turning the handle to 180 degrees, the entire window opens inward from the sides, offering easy access for cleaning and excellent airflow.

This dual functionality makes them the perfect glazing solution for modern living, providing flexibility, safety, and ease of maintenance.

A popular window choice for homeowners of high-rise flats, luxury apartments, and family homes with children, where accessibility and security are key considerations.

How do Tilt and Turn Windows Work

The mechanism is simple yet sophisticated. A single handle controls both functions:

One turn of the handle releases the top for inward tilting and secure ventilation.

A second turn allows the window to open fully from the side, just like a traditional inward-opening casement window.

This innovative design gives homeowners greater control over airflow and comfort, while the side-opening action also serves as a practical fire escape, compliant with UK building regulations.

Benefits for Berkshire, Surrey, and Hampshire Homeowners

European Tilt and Turn Windows are distinguished for their exceptional design, outstanding efficiency and unmatched quality that makes them a popular choice for properties across the South East:

Flexible Ventilation

The tilt feature allows fresh air to circulate safely without fully opening the window — perfect for overnight airflow or when you’re away from home.

Easy Cleaning

The inward-opening design allows both sides of the glass to be cleaned from inside the property, which is especially useful for upper floors and apartments.

Enhanced Security

When tilted, the window remains securely locked, providing peace of mind without compromising ventilation.

Energy Efficiency

Modern European Tilt and Turn Windows are manufactured with the highest-quality materials and engineered with meticulous attention to detail, featuring advanced glazing and thermal seals that help retain heat, reduce energy loss, and lower utility bills.

Design Versatility

Available in a variety of materials, finishes, and colours, these windows can complement any architectural style — from contemporary new builds to traditional homes.
Materials and Finishes

At Thames Valley Windows, our European Tilt and Turn Windows are available in a range of materials to suit different design preferences and performance needs:

Internorm uPVC Windows

Internorm offers homeowners across Berkshire, Hampshire, Surrey, and Oxfordshire a premium range of energy-efficient uPVC windows. Cost-effective solution for both contemporary and traditional homes, these windows combine exceptional performance with timeless style.

uPVC/Aluminium Composite Windows

Internorm’s award-winning triple-glazed uPVC-aluminium composite windows deliver outstanding energy efficiency and contemporary aesthetics.
They are an ideal choice for Passivhaus designs, self-build projects, and retrofit developments seeking cutting-edge thermal performance.

Timber/Aluminium Windows

Timeless and natural Internorm’s timber-aluminium composite windows blend natural warmth with modern durability.
They are a preferred option for homeowners, architects, and developers throughout Berkshire, Hampshire, Surrey, Oxfordshire, and the wider Southeast.

Perfect for both renovation and new-build projects, they offer long-lasting beauty and sustainability.

Choose from a broad palette of colours and finishes — classic white, modern greys and blacks, or woodgrain effects for an authentic traditional look.

Energy Efficiency and Thermal Insulation

Energy efficiency is at the heart of every European Tilt and Turn Window solution we design and install.

Our double or triple-glazed systems feature high-performance seals and insulating frames that reduce drafts, prevent condensation, and improve thermal performance.

Many of our European windows exceed UK Building Regulations for energy efficiency, helping homeowners across Berkshire, Surrey, and Hampshire create warmer, more sustainable homes while reducing heating costs.

Security and Safety Features

Security is always a priority. Our European Tilt and Turn Windows feature multi-point locking systems, reinforced frames, and toughened or laminated glazing for maximum protection.
The tilt position enables safe airflow while keeping the window securely locked — an ideal feature for family homes. Look for models that meet PAS 24 certification for enhanced protection against forced entry.

Ideal for Every Property Type

  • European Tilt and Turn Windows are suitable for a variety of home styles:
  • High-rise Flats & Luxury Apartments and Penthouses: Safe, convenient inward cleaning and controlled ventilation.
  • Contemporary New Builds: Minimalist frames with large glass panels for contemporary aesthetics.
  • Traditional Properties: Timber-effect finishes that preserve classic architectural character.
  • Family Homes: Ensure ventilation is secure to protect young children while maintaining airflow.

Maintenance and Longevity

Tilt-and-turn windows are built to last. uPVC and aluminium frames are virtually maintenance-free — wipe with soapy water to keep them looking their best. Timber frames may need occasional recoating to preserve their natural beauty.

Regular maintenance of lubricating hinges and handles will ensure smooth operation. With proper care, European Tilt and Turn Windows can last for decades.
