Special Function Roof Windows

Every project has specific goals. Building a new bathroom? You’ll need water and condensation resistant windows. Designing a loft conversion above a flat roof? You might want security windows to reduce the risk of burglary. Whatever your project, we have the speciality roof window to suit.

Thermal Efficiency

Windows can be a weak point in a building’s thermal insulation - but not with Dakea. Our Energy range in particular, such as Better Energy and Vision Energy, are designed to maximise insulation efficiency. You can build warmer houses that use less energy. All our roof windows, even in our most affordable ranges, use low E-coating to reflect heat. They reduce heat loss through a building’s roof windows.

Security Windows

If security is a part of your project’s goals, consider selecting our most secure roof windows. With class P4A security glazing, a toughened external pane, and reinforced hinges - among other features - they’re a great addition to building security.

Moisture Resistance

If you’re building a bathroom or kitchen, it's important to consider the impact of moisture. Our range of PVC windows is a fantastic choice for areas prone to moisture. In addition, the thermal efficiency of our range will help to reduce condensation on windows. Why not use our window configurator tool to help you find the best roof windows for your project? Explore Dakea’s professional roof windows. We design and build for quality, a professional finish and affordable prices. In our expansive range, there is a roof window for every build.

Roof windows vs Skylights

At Dakea, our roof windows are all suitable for use within occupied rooms of the home or workplace as they offer quality insulation to keep occupied rooms warm. On the other hand, skylights are designed for unoccupied rooms such as lofts or garages. They promote good light and ventilation in these spaces.

At Dakea, we prioritise energy efficiency in our roof windows to help reduce heat loss and lower energy bills:

Ultima Energy Series

Our top-of-the-line energy-efficient roof windows featuring:

  • Triple glazing with U-value as low as 0.99 W/m²K
  • Argon gas filling for superior insulation
  • Warm edge spacers to minimize thermal bridging

Better Energy Series

High-performance roof windows suitable for most residential applications:

  • Double or triple glazing options
  • U-values ranging from 1.1 to 1.3 W/m²K
  • Low-E coatings to reflect heat back into the room

  • Wooden frames: Natural look, excellent insulation, suitable for most applications
  • PVC frames: Moisture-resistant, low maintenance, ideal for bathrooms and kitchens

  • Double glazing: Cost-effective, suitable for most UK climates
  • Triple glazing: Maximum energy efficiency, ideal for colder regions or north-facing windows
