Wishful thinking in this winter weather don't you think ? My she-shed has a rather large sliding glass door which faces north and will give wonderful bush views with light and warmth from the winter sun. However, in summer I don't want to lose the view by using blockout type window coverings to keep cool. I've already purchased light filtering panel blinds but I'm thinking of having the glass covered with that window tinting film used for windscreens. Would love to have advice or opinions from other workshoppers if anyone would be so kind. Thanks in advance. You wonderful people have no idea how much your help means to this old girl. Cheers.
