9 March 2006 Tim Renouf Wren Industries P/L Unit 5, 19 Abbott St. SANDRINGHAM VIC  3191 Dear Tim, RENSHADE  foil insulation for windows We live in the Port Stephens area and have employed RENSHADE in a couple of ways to reduce the internal temperature in our house. Structure is a conventional brick veneer with a colourbond roof. A standard insulation foil building blanket backs the colourbond roof while the ceiling is further insulated with a foil product. Brick veneer walls are insulated with batts and foil sisalation.   Our remaining vulnerability to heat intrusion was the glass windows and doors. We have applied RENSHADE with the supplied Velcro fixings to our NE facing office/bedroom large sliding doors and window. is room receives full sun for a few hours in the morning and became unpleasantly hot with normal blinds fitted. After the RENSHADE treatment temperatures dropped significantly and the room is now usable throughout the day. During winter we remove the RENSHADE and store it. In the lounge area we have made chain-drive roller blinds to insulate glass block wall skylights, and   roller blinds are also fitted to other sun exposed windows to control heat at various times of the day.   RENSHADE makes up fairly easily into roller blinds, the edges being ‘hemmed’ for strength. e roller blinds exhibit a higher quality appearance than many conventional blind materials, although this will of course be a matter for personal taste. While working away from home this last summer my living accommodation was a west facing room in the Blue Mountains where temperatures regularly exceeded 35 degC. As a temporary heat reduction measure we attached RENSHADE to the flyscreen frames, achieving very good results - significantly reducing daily heat build up.   I felt quite guilty removing the RENSHADE when I departed, leaving a hot box for the next occupant.
