With over 250 size and glazing options, FAKRO not only offers the largest standard range of roof windows in conservation style but routinely manufactures them to bespoke requirements. In conservation areas, planners are increasingly favouring window positioning low within the roofline so FAKRO’s choice of 3 installation depths and scope to fit either to rafters or battens is a major benefit. No other manufacturer does this and for slates in particular, installing roof windows in such a way gives them a neat and unobtrusive appearance. For deeply profiled tiles too the facility to raise installation depth is similarly effective. For slates, an ELJ flashing is used with windows fitted 3cm lower than the standard installation depth.
