If you have heat problems in a room, exterior blinds are the answer. They give you all the advantages of a venetian - on the outside of the window. The fact that the sun cannot reach the glass means a great reduction in room temperature. An added advantage is that you can still look out the windows while being shaded from the sun. The venetians are supplied in 70mm slat width only and are stabilised with stainless steel rigging wires, tensioned by springs. The cedar slats are finished in your your choice of colour (we use 'Feast Watson' & 'Cabot's Ranchhouse Stains') or they can be treated with a clear wood preservative to maintain the natural colour. There are also power savings for cooling and heating.
