Aluminium roof lanterns are glazed structures installed on flat roofs to maximize natural light and create a bright, spacious feel in rooms below. They are essentially an elaborate skylight, featuring a frame typically constructed from aluminium alloy and angled glass panes, creating a pyramidal or elongated prismatic shape. Aluminium is a popular choice for these structures due to its durability, modern aesthetics, and thermal efficiency.
Key features and benefits
- Modern Design: Aluminium's strength allows for slimmer, less intrusive frames, maximizing the glass surface area and the amount of natural light that can enter the room.
- Durability and Longevity: Aluminium is a robust material that withstands harsh weather conditions, corrosion, and warping, ensuring a long lifespan of decades with proper installation and maintenance.
- Thermal Efficiency: Despite aluminium being a good conductor of heat, modern aluminium roof lanterns incorporate thermal breaks, such as polyamide nylon, within the frames, significantly improving their insulation properties. Combined with double or triple glazing, this helps maintain comfortable temperatures year-round, reducing heating and cooling costs. Some systems boast U-values as low as 1.0 W/(m²K).
- Low Maintenance: Aluminium is naturally resistant to rust and corrosion and requires minimal maintenance, typically only needing occasional cleaning with soapy water to keep it looking pristine.
- Customization: Aluminium roof lanterns are available in various styles and sizes, including bespoke options. They can be powder-coated in a wide range of RAL colours to match any home's architectural style and decor, whether traditional or modern.
- Sustainability: Aluminium is a highly recyclable material, making aluminium roof lanterns a more environmentally friendly choice compared to alternatives like uPVC.
