Inward foil surface emits or re-radiates 3% of radiation, with airspace * RENSHADE perforated surface area = 10%. Aluminium surface area = 90%* Inward radiant heat flow = estimated 85% reduction* Outward winter heat loss = reduction unspecified, but considerable* Effective typical summer period in southern Australia – October to March. APPLICATIONS * RENSHADE with Velcro (included): cut to fit and fixed against inside of glass (40x 22mm diam’ spots – upon request per 5m rolls) for vertical, angled and irregular shaped glass, + atriums, greenhouses, skylights.* RENSHADE Holland Blinds: chain-drive best suited for long drop windows.

For Holland Blinds take RENSHADE to blind makers.
BENEFITS* Estimated 85% reduction in radiant heat flow – direct sunlight, reflected heat or ambient air temperature* No glare, gentle filtered light. Less damage to fabrics/timber flooring. Assists computer screen reading.* See-through insulation - external view maintained with total privacy during daytime - impossible to see in. Reverse optical effect at night time - privacy requires use of internal blind.
* Airconditioning use will be considerably reduced or eliminated. Natural ventilation with cooler evening
temperatures plus ceiling fans will commonly be sufficient. Lower power costs for occupants and reducedstate/national summer peak load electricity demand - Reduces the need for expensive double-glazing. * RENSHADE sheets can be removed, rolled up, stored carefully and reused repeatedly but care is needed. * Transparent roofing is commonly too hot to sit under – RENSHADE is the answer. * Adequate winter light will penetrate RENSHADE to maintain plant growth.
