Your home can remain cool and comfortable despite outdoor temperatures thanks to the strategic installation of external Venetian blinds. These sophisticated shades not only enhance the aesthetic appeal of your property but also serve as an intelligent investment, significantly reducing energy costs by optimising natural light and maintaining ideal indoor temperatures. With this in mind, the cost for external Venetian blinds is well worth it, being not just window treatments but integral to a luxurious, energy-efficient home.
When it comes to choosing outdoor Venetian blinds that checks all the boxes in quality, few can compare them to the one manufactured by Horiso.
Features that are ahead of the curve in innovation and style
Available at A’besco, Horiso’s Australian-made external Venetian blinds are a smart, energy-efficient option for your external windows. Proven to reduce thermal heat gain by up to 93%, they can help you minimise energy use, optimise airflow and prevent UV damage to your interiors. They can also help you achieve a high environmental green building rating.
The tilting slats allow you to control light flow, minimising the need for artificial lighting. The durable aluminium component radiates heat and has low absorption and transmission – which can help keep your interior temperatures moderate year-round. They can even reduce eye irritation and improve computer screen visibility by controlling solar glare.
They are also made from high-strength, shrink-resistant and 100% reinforced Kevlar ladder braid components that will stand the test of time. This means they provide years of reliable operation with minimal maintenance. The pelmet is made from extruded aluminium, and they utilise stainless steel 316 marine-grade cables as well as high-quality PE slat coil. This makes them heavy-duty, commercially-graded and engineered.
Fast and specialised solutions for your home’s unique needs
Horiso external Venetian blinds are made locally and typically have a four-week lead time. This means there are no international freight delays, and you’re also supported in terms of parts and service. These blinds can also be tailored to your space’s specific needs and work within your budget constraints. Simply schedule a consultation, inform us of your needs, and we’ll supply you with the full details on the installation process, the cost of external Venetian blinds and how they provide the most return on your investment.
Choice of operating systems
These blinds are easy to operate, and you have the option of manual, motorised remote control, or fully integrated automation. With automated control, you can set the slats to tilt at certain angles at specific times of the day, so as to optimise air-flow and shade at varying sun angles.
Key Features
Easy to operate
Choose from manual, motorised remote control or fully integrated automation.
Ease of installation
Customise the system widths and lengths, and install on internal, external and double skin facades.
Energy efficient
The aluminium composition of these blinds reflects heat, helping keep interiors cooler in summer and warmer in winter.
Optimise natural light
The slats of these blinds can automatically tilt to optimise shading at varying sun angles.
High quality, durable components
Made from high-strength, shrink-resistant and reinforced 100% Kevlar ladder braid, these blinds have a slimline profile which makes them less prone to damage or denting.
Quality manufacturing
All steel extrusions and injection moulded parts are manufactured in Australia, while ladder braid, lifting tapes and aluminium coil are imported from Europe. The final product is fully assembled and tested in Sydney and comes with a five year manufacturer’s warranty (see Horiso terms and conditions for details)
Aluminium Slats
These crowned aluminium slats are made from a highly elastic alloy, which makes them flexible, scratch-proof and shock-proof. Double omega punching (which comes standard on external and double skin facade installations) combined with the ladder braids ensure the slates close smoothly and are aligned and stable in most weather conditions.
Horiso’s powder coating finishing processes and products are approved by Qualicoat, an internationally recognised powder coating licensing authority.
Standard Colours
Standard Widths
80 mm / 100 mm / 150 mm
Perforated Slats
The perforated slats are available in Horiso’s 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 which allow 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 allowed to pass through. This means that while solar heat gain and glare is significantly reduced, including harmful UV rays, natural light can still flow into your interiors.
Timber Slats
Horiso timber slats are manufactured from sustainably managed forests in both Western Red Cedar, Paulownia and Accoya® varieties.
Western Red Cedar
A robust timber under which can endure 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.
Timber Widths: 80mm X 4mm
Paulownia
A reliable, resilient, lightweight and straight grain hardwood timber for internal installation.
Timber Widths: 84mm x 5mm
Accoya®
Accoya® is a modified timber made using a process called acetylation: a cutting-edge patented technology which 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 get in touch with the team at A’besco to learn more about Accoya® slat sizes, colour stains and lacquered finish options.
Specialty Venetian Blinds in double skin facades
Horiso External Venetian Blinds are also suitable for installation in double-skin facades. Blinds installed between the two skins / facades can help optimise the management of solar energy as it passes through the facade – benefiting both the building and its occupants.
