The perfect solution for comfortable roof access when indoor headroom is limited or you need a nice spacious roof hatch. We can adapt the dimensions for comfortable roof entrance with enough headspace.

Rooftop revolution
The Three Wall Box is a breakthrough in rooftop access. An electric roof hatch, but different. Integrated between three walls, the Three Wall Box is the perfect solution for comfortable access to your roof terrace.
Innovation
Beautiful glass box for comfortable access to the roof terrace:
– Slides open up to 50% at the push of a button
– Attractive appearance: mechanisms and electronics hidden
– Good insulation: very low U-value
Always tailored to size
The dimensions of the Three Wall Box roof access are up to 6m2 with a maximum span of 2.4m, the height ranging from 0.4m to 1.5m. Need a larger span or surface? Take a look at our other roof accesses. In fact, the all-glass Sliding Box can be manufactured even larger. We would be happy to advise you on the ideal size for your project.
Box or rooof house for your roof terrace?
A rooftop house is not allowed on every roof. The Three Wall Box is the ideal solution for comfortable access to your roof terrace. In fact, this box may be used on roof terraces where the maximum permitted building height on the roof is 1.20 meters.
Wall mounting
Many properties have a wall that extends onto the roof. This is ideal to mount the Three Wall Box against. Both side walls can be made of wood frame construction or, for example, plaster blocks. For connection details, please contact us.
Always useable
Manual “override”: can also be opened manually in case of power failure.
