A technical advice<\/a> for this model of box. Half-header boxes are suitable for closures with a transom length of up to 4 metres (i.e. a 4.19 m box).<\/p>\n\n\n\n

Installed in the factory on the joinery, the roller shutter is housed in the masonry, under a half-lintel box. This makes it invisible from both inside and outside. <\/p>\n\n\n\n

The bay unit guarantees perfect air tightness, as no stray air can enter through the shutter. <\/p>\n\n\n\n

Be careful, though, as installing a bay block shutter is more complex than a traditional roller shutter, and requires a great deal of expertise. As these shutters are inseparable from the windows they insulate, they must be installed perfectly, otherwise problems with closure and insulation will arise very quickly. <\/p>\n\n\n
