<p>This conservatory has a roof formed with a Vitral patent glazing system which has been fitted over the top of the oak rafters. Vitral is one among several high performance yet affordable glazing systems on the market. Two of the lights are openers and hinge from the top of the panel. Note the use of Lindab galvanised steel guttering, so much nicer than plastic! (Photography: Duncan McNichol)</p>
