Transform traditional spaces with maximum daylight while enhancing indoor comfort with great thermal efficiency.

The VELUX Heritage conservation roof window is designed to be in-keeping with heritage aesthetics of historic buildings. Slim and elegant and sitting flush to the slates, it blends beautifully into the roofing material.

Thoughtfully co-created with Architects and Conservation Officers, it enhances modern living, while maintaining the building’s original character.

Suitable for roof pitches: 20°-65°
  • Authentic top-hung design
  • Crafted glass-to-edge technology for a clean appearance

Harmonious integration in historic roof

The design of the Heritage conservation roof window alludes to the traditional cast iron window with a slim elegant profile, sitting flush to the roof and with a black external finish that blends in naturally with the roofing material for complete period authenticity.

It also features a vertical glazing bar in reference to traditional attic windows. This attention to design detail makes it the ideal choice for retrofitting and updating loft spaces in historic properties.

Modern comfort in heritage design

As the owner of a historic property, you can now create new spaces full of daylight and fresh air whilst respecting the character of the building. Although it looks traditional, there’s nothing old-fashioned about the Heritage conservation roof window. For optimal indoor comfort, its glass-to-edge technology lets in as much daylight as possible and delivers a high-energy performance.

For additional comfort, you can choose VELUX pleated blinds for flexible light adjustment in a stepless design that can be placed anywhere in the window.

High energy performance to keep energy costs down

The VELUX Heritage conservation roof window offers a guaranteed thermal efficiency U-value of 1.3 W/m2K to keep your rooms warm and cosy. ​

Moreover, the roof window glazing comes with premium features like safety glass and a toughened outer pane for extra security. The easy-to-clean coating prevents dirt sticking to the pane, a UV filter will protect your furniture from fading as well as rain noise reduction. In other words, everything modern life requires from a roof window.
