Comfort²Vie® Extensionsérie 7700

The flat-roofed house extension

The Confort²Vie® extension is the highlight of the conservatory range. This extension has everything to please: a flat roof design, increased thermal and acoustic performance and reinforced waterproofing. Its 70 range aluminium structure, its flat roof with self-supporting insulating panels and its EPDM membrane waterproofing make this extension Sepalumic’s flagship product.

The extra-flat roof with only 1.15° slope, a single-slope dome with triple glazing, flat ceiling interior finish, and lighting integrated into the ceiling are the key features of the Confort²Vie® extension.

Its aluminium structure, with a 70 mm section, has a thermal break, guaranteeing a very good insulation of the profiles. This system eliminates the cold wall effect in winter and reduces the effects of condensation.

Extension Confort²Vie®

To ensure maximum comfort, the flat roof is made of 164 mm thick insulating sandwich panels. This opaque panel consists of aluminium plates and a central insulation of extruded polystyrene. It provides good thermal and acoustic comfort. The waterproofing is provided by a prefabricated 3D EPDM membrane, which is appreciated for its waterproofing characteristics, its durability and its time saving installation.

Manufacturing and installation are optimised thanks to the technology of the insulating panels and their joint key and the customised 3D EPDM membrane, prefabricated in the workshop and ready to install. The result: no welding on site, no falls, safe installation without waterproofing work and no intervention by other trades.

This “living room” extension concept allows for all kinds of variations: extension of the dining room, integration of a kitchen, a living room.
