After reading – http://www.yourhome.gov.au/passive-design/shading for the Eastern and western elevations > Adjustable shading is especially useful for eastern and western elevations, as the low angle of the sun makes it difficult to get adequate protection from fixed shading. Adjustable shading gives greater control while enabling daylight levels and views to be manipulated. Appropriate adjustable systems include sliding screens, louvre screens, shutters, retractable awnings and adjustable external blinds.
I added a shade cloth to the kitchen Hi-lite windows facing west as the glare in the kitchen was very bright. Originally I was going to set up a pulley retractable system but ended up too complicated for a small system. During winter, I will just manually retract these and use cloth pegs or some sort to hold the shade cloth instead. Now that this one works, I started on the shade cloths for the two other bedrooms.
Items used (most from Bunnings):
•2mm wire cable, 10m length (x 2 pack) – $14.41 = $28.81 – I would have only used one pack if it was not due to trial and error making the first shade cloth.
• 2mm Swage (x 9 pack) – $2.80ea = $25.20 (you can buy 2mm wire rope grips @ $6.27 for two then no need for Swage or Swage tool) though it does make the wire rope look bulky.
• Swaging tool to cut and crimp the swage – $39.95
• Galvanised Hook and eye turnbuckle (x 9) – $5.89ea = $53.01
• 12mm Eyelet repair kit off (with 100 grommets) off ebay ~ $15 (butterfly clips are useless.)
• 25mm key rings (5 in a pack x 2 packs) – $4.26ea = $8.52
• Plastic key tags with holder (x 3 packs) – $2ea = $6.00 (should have bought from Cheap as Chips instead of Bunnings, don’t buy from Reject shop – 4 for $2.50)
• Ramset 8 x 45mm DynaBolt Plus Hook Opening Bolt (x 9) – $1.15 each = $10.35
• 8mm masonry drill x 1 – $6.93
• Marine grade stainless steel 6mm pad eye boat yeach outdoor shade sail (x 9) off ebaybay – $12.99 for 4 (inc postage) and you can buy singles = $27.00
• Shade cloth (90% UV beige, 15 year warranty at $16.35 per linear meter, bought 4m = $65.40 ), as it came in 1.83width, I cut the cloth into half.
• 3mm drill
• 10g x 16mm Galvanised Hex Head Metal Screws
• Drill driver
Shade cloth – around 8 key rings, Marking the locations for the eyelets and measurements, size varies during to windows and air cond pipes. As it came in 1.83width, I cut the cloth into half. Folded the corners in ~ 3 to 4cm and 5cm size and used the eyelet to hold it in place.
Worked out to be ~$100 each window (exclude labour), seems expensive but overall made a difference in temperature in kitchen area and bedrooms. Our bedroom was 30 degrees Celsius (no fan or a/c switched on, during yesterday’s 38 degree heat).
Word of warning – better to buy extra swage and then returning unopen ones back to Bunnings than making multiple trips. Up to you if you wish to use 2mm rope thimble
