We manufacture to original Land Rover quality using original shape Land Rover aluminium profile and locks/catches. Our windows are made using E43R toughened safety glass – Omega Automotive has been manufacturing automotive safety glass and many other vehicle parts for many decades and supplies all around the World to various automotive firms.
Many old windows rattle, leak and are draughty – our replacement land rover defender windows will solve that – in addition if you order the tinted versions you will be reducing glare and reflecting some of the heat on a hot day. The tint is factory-prepared – the glass is actually tinted and not a stuck on film which can peel off – film is not simple to apply in any case as the glass has to be removed.
