Blown, misted and inefficient glazing not only costs money in loss of heat but it can quickly damage the internal finish of your VELUX window.  When you come to replace your glazing its a good chance to upgrade.  We use upgrade conversion kits to allow a modern equivalent to be installed greatly improving the sound and heat insulation.
