The Evaya ev93D is Instaco’s room-darkening external venetian blind, purpose-built for Queensland homes and commercial projects that need serious light control — not just shade. The unique 93mm interlocking slats close out unwanted light almost completely while keeping a minimal stack height when retracted, making it the go-to external venetian for bedrooms, media rooms and any space where glare and light leakage are the priority, not just heat.

The ev80 and ev93D are driven by German Engineered, market leading, Geiger GJ56 Venetian Blind Motors, a perfect combination with no compromise. These are the most innovative, practical, reliable and quietest drive solutions in their class.
Built and Engineered for Australian Conditions
The ev93D is roll-formed and machined in Australia, chemically pre-treated and stove-enamelled for a finish that holds up under real Australian sun — not just a coating that fades after a season or two. Its aluminium construction resists the warping, cracking and corrosion that timber and PVC shading struggle with in extreme heat, while the UV-resistant Kevlar/aramid guidance system and UV-stable Texband lifting tape are engineered specifically for long-term sun exposure, not general indoor use. The slats’ Neoprene rubber inserts add genuine thermal reflective properties on top of the shading itself — so you’re not just blocking the sun, you’re reducing the heat it carries through. Built for Queensland conditions and beyond, the ev93D is designed to perform reliably through every Australian summer, not just look good in the showroom.
External Venetian Blinds With True Room-Darkening Control
Where the ev80 is built for versatile light and heat control, the ev93D external venetian blind takes it further — the “D” stands for its dedicated room-darkening capability. Every slat is roll-formed and machined in Australia, chemically pre-treated and stove-enamelled for genuine resistance to Queensland’s UV and heat, with a Neoprene rubber insert on each slat edge that cuts noise and boosts thermal reflectivity. Whether you’re blacking out a Brisbane bedroom or controlling glare in a commercial fit-out, the ev93D delivers precision without compromise.

The unique 93 mm slats have been designed to enhance wind stability and light control, with the D in its name directly referencing its room darkening capabilities. The clever contour of the slat allows each blade to interlock perfectly to block out unwanted light whilst at the same time allowing minimal stack heights when retracted. These features, when coupled with a Neoprene rubber insert on the front edge of each slat to prevent noise and damage whilst enhancing its thermal reflective properties, create one of the most technologically advanced automated louvre systems of our era.
In addition to these developmental design benefits, each ev93D is constructed with Hagofix slat attachment and guidance systems. The Hagofix system embeds a stainless steel connector into the rolled edge beading of the slat which then attaches to a spigot fastened to a Kevlar/aramid woven tape. This provides extremely secure fastening and stability and allows extensive and incremental control of blade angles. It also ensures that each slat cannot swivel or slide out of position. The UV resistant woven synthetic connecting element, with exact fold points, further acts to provide perfect closure and minimal stacking.
The ev93D is typically lowered closed (vertically at 0 degrees) and raised in the horizontal (90 degrees open) position. Stable, secure and refined operation is also guaranteed by the Zamac side pins which are mechanically riveted to the slats and engage in our range of extruded aluminium side guides. Each side channel has a patented keder insert to reduce any associated noise and friction. Similar to the ev80, the lifting system relies on a UV stable Texband tape which passes through Precision machined, punched and drawn holes along the length of the slats
