lantern replacements

People are going off cheap, nasty and ugly roof lanterns and we are being asked more and more for large one piece all glass rooflights to replace their tired old fashioned and pastiche roof lanterns.

It is a design that more and more people are hating, too many roof bars to ruin the inside/outside view , take forever to heat up the room as you have to heat all the ‘dead space’ of the roof lantern. They also gather too much heat as they stick up and will overheat even when the sun is at a low level and can often ruin the view from a bedroom or landing with the roof lantern sticking up creating a visible barrier into the garden.

In truth getting the detail correct on lantern replacement projects is critical.
