Specialty Venetian Blinds

High performance, technically advanced venetian blind systems.
Specialty Venetian Blinds are External Venetian Blinds which can be specified for external or internal use with the primary benefit of reducing solar heat gain whilst maximising the use of daylight, contributing to higher human comfort and productivity levels.
The blinds are manufactured and engineered at our facility in Sydney using high quality aluminium slats and components which can be raised, lowered and tilted by motorisation or integrated automation control.

Key Features
Easy to Operate
System operation by manual, motorised remote control or fully integrated automation.
Ease of Installation
Customisation of system widths and lengths offer retrofit installation to internal, external and double skin facades.
Aluminium’s Innate Properties
High radiation reflection, low radiation absorption and low transmission values. Reduction in the energy requirements of mechanical heating/cooling systems.
High Wind Resistance
Head box, slats, cable guides and extruded aluminium base rails are engineered to withstand extreme wind loads.
Maximise Use of Daylight
More efficient cross ventilation can be achieved by slats automatically tilting to optimise shading at varying sun angles.
High Quality and Durable Components
high-strength, shrink-resistant and reinforced 100% Kevlar ladder braid.
Aluminium Slats
Crowned aluminium slats are made from a highly elastic alloy, making them flexible, scratch-proof and shock-proof. Double omega punching, (standard on external and double skin facade installations) combined with the ladder braids ensure smooth closing of slats, also retaining slat alignment and stability in most weather conditions and minimise excessive movement.

Horiso's powder coating finishing processes and products are approved by Qualicoat, an internationally recognised powder coating licensing authority.

Perforated Slats
Perforated slats are offered in our standard aluminium colour range. Custom colours can be requested using the RAL colour system (subject to minimum quantity requirements).

Perforated aluminium slats feature tiny circular holes allowing a small amount of light through the blind when it is closed or tilted. A large amount of natural light is excluded with a small percentage of light allowing to pass through. Solar heat gain and glare is significantly reduced including harmful UV rays. The small percentage of light that is allowed to pass through allows a partial view through the window to be maintained.
Timber Slats
Horiso selects timber for the manufacturing of timber slats from sustainably managed forests in both western red cedar, paulownia and Accoya® varieties.
Western Red Cedar
A dimensionally stable timber under most weather conditions and is not prone to shrinkage or swelling.
Due to its versatility, it can be used for both internal and external applications.
Light Stain
Medium Stain
Dark Stain
Timber Widths: 80mm X 4mm
Paulownia
A reliable and resilient light weight and straight grain hardwood timber for internal installation.
PT200 - Natural
NC300 - Natural
PT205 - Golden Oak
PT224 - Mahogany
PT150 - Limed White
PT230 - Antique Grey
PT215 - Dark Java
PT235 - Black Walnut
Timber Widths: 84mm x 5mm
Accoya®
Accoya® is modified timber in which a process called acetylation, a cutting-edge patented technology, enables it to resist rot, defy the elements and stay strong for decades. Accoya® wood is sourced from sustainable sources, including FSC® and Cradle to Cradle™ Gold environmental certification. It can be used for both internal and external applications.

Please make contact for more information on Accoya® slat sizes, colour stains and lacquered finish options.
Specialty Venetian Blinds in double skin facades
Horiso external venetian blinds are suitable for installation in double-skin facades. External venetian blinds installed between the two skins / facades maximise the management of the solar energy passing through the facade. Operational control of the external venetian blinds optimise the benefits for both the building and the occupants.
