Winslot® is always supplied as a complete architectural system, including the precast concrete elements and the Winvent® glazing inserts in the options available as one complete system.
This system has been painstakingly designed, tested and approved and is a comprehensive passive sun control facade system. Therefore specifying or pricing this system should always include the Winslot® elements plus the Winvent® insert. This is to ensure that the system will function correctly for many years and perform exactly as it has been specified by the architect, which in turn guarantees that the client is getting only the very best Winslot® solution for their project.
The Winslot® Concrete Components
Precast high strength, high density, low permeability concrete.
Our Winvent® range
Specifically designed and engineered to integrate perfectly with the Winslot® System.
Winvent® Top Hung
The aluminium Top Hung projecting out Winvent® is supplied factory glazed (silicone flush glazing), 4mm Float Glass as standard. Manufactured from aluminium extruded sections, which are epoxy powder coated finished. The handle is Injection Moulded, Glass Fiber Reinforced PA 6 Nylon in black. Weather seals are wool pile. The sliding friction stays are in 304 stainless steel.
All glass types may be specified for Winvent. Architect to specify appropriate glass type required per project. Fly screens and burglar bars may be factory fitted as additional accessories.
Please contact us to order or check stock availability within South Africa.
Winvent® Dual Tophung
The aluminium Dual Tophung projecting out Winvent® is supplied factory glazed (silicone flush glazing), 4mm Float Glass as standard. Manufactured from aluminium extruded sections, which are epoxy powder coated finished. The handle is Injection Moulded, Glass Fiber Reinforced PA 6 Nylon in black. Weather seals are wool pile. The pantograph sliding friction stays are in 304 stainless steel.
All glass types may be specified for Winvent. Architect to specify appropriate glass type required per project. Fly screens and burglar bars may be factory fitted as additional accessories.
Please contact us to order or check stock availability within South Africa.
Winvent® Fixed Frame
The aluminium fixed frame Winvent® is designed to match the opening Winvent® Top Hung. Manufactured from superior quality aluminium extruded sections. It is supplied factory glazed (silicone flush glazing), 4mm Float Glass as standard.
All glass types may be specified for Winvent. Architect to specify appropriate glass type required per project. Burglar bars may be factory fitted as additional accessories.

Winvent® Fixed Direct Glass
We have developed one of the most cost-effective ways to allow light into the building. A pane of glass (no aluminium) is directly installed into the glazing rebate of the Winblok® frame using our Neutral-Cure Silicone Sealant.
As a standard we supply 4mm Toughened Safety Glass (TSG) for the Fixed Direct application, as we have found that the TSG types of glass are most resistant to cracking when applied directly into the Winblok® Concrete Frame. Cracking of glass in the Fixed Direct Application is caused by expansion and contraction of different materials, as the glass is not 'protected' by an aluminium housing. Float and Laminated Glass types do not perform well when used in the Fixed Direct application. The Architect is to specify the glass type required.
Winvent® Central Pivot
The aluminium central pivot Winvent®, designed for high level pole action with a pull ring spring catch, is supplied factory glazed (silicone flush glazing), as a standard we supply 4mm Toughened Safety Glass (TSG) for this application. It is manufactured from aluminium extruded sections which has an epoxy powder coated finish. Weather seals are wool pile and the centre pivot hinge is a nylon friction bearing.
Due to the nature of this window type, we recommend Toughened Safety Glass (TSG) for this application. Burglar bars may be factory fitted as additional accessories.
Please contact us to order or check stock availability within South Africa.
Winvent® Bottom Pivot
The Bottom Pivot Winvent® inward opening is designed to be used where projecting out, or a Central-Pivot Winvent®, may be inappropriate. This Winvent® is supplied with a pull ring spring catch and comes factory glazed (silicone flush glazing), as a standard we supply 4mm Toughened Safety Glass (TSG) for this application. It is manufactured from aluminium extruded sections which are epoxy powder coat finished. Weather seals are wool pile. The Bottom Pivot is set 100mm from the bottom and has a ‘stop’ attached to limit the opening width.
Due to the nature of this window type, we recommend Toughened Safety Glass (TSG) for this application. Burglar bars may be factory fitted as additional accessories.
Please contact us to order or check stock availability within South Africa.
Winvent® Flyscreen*
The Flyscreen for the Winvent® is manufactured from an aluminium extrusion frame into which a fibre mesh is secured with a rubber gasket. It is top hung on the frame with glass-reinforced nylon hinges and opens inwards secured by a catch.
*The Flyscreen is only available as a factory fitted item.
Please contact us to order or check stock availability within South Africa.
Winvent® Glazed Louvre
The Winvent® Glazed Louvre provides an opening window where projecting out, Central-pivot or Bottom-pivot Winvent® are impractical. An aluminium louvre blade mechanism is mounted in an aluminium Winvent® frame. The blade mechanism and frame are epoxy powder coated. As a standard we supply 5mm Float Glass for this application. Glazed Louvres may be used for ventilation in conjunction with Winblok® Winguard or special burglar bars in high security applications.
Please contact us to order or check stock availability within South Africa.
Winvent® Fixed Louvre
The Winvent® aluminium fixed louvre provides permanent fixed ventilation for squash courts, switch rooms, ventilation ducting and other similar applications. They will not totally exclude entry of wind driven rain. Aluminium Fixed Louvres are manufactured from extruded aluminum louvre blades carried on tubular mullions and mounted in an aluminium Winvent® frame.
Fly screens and burglar bars may be factory fitted as additional accessories.
Please contact us to order or check stock availability within South Africa.
Winvent® Burglar Bars
Winvent® Burglar Bars are manufactured from 12 x 10mm solid aluminium bars, and factory fitted with countersunk pop rivets as an added accessory.

Winvent® is SANS-10400XA & SANS 613 Compliant
Our Winvent® Top-Hung and Fixed-Frame windows are compliant with both SANS 10400-XA (energy performance) and SANS 613 (air and water filtration/penetration).
We are able to provide the Simulated Energy Performance Rating Certification for all design permutations using the Winvent® Inserts in the Winslot® System on request – confirming compliance with SANS 10400-XA simulation and calculations according to National Fenestration Rating Council(NFRC) and ISO standards.
Winslot® Straight Assembly
Winslot® straight assembly is a vertical stack of straight blades consisting of sill, intermediate louvres and lintel that are held in place by left and right reveals spacers inset and built into the wall at each end. For long spans, a mullion can be used for additional support. The number of intermediate blades may vary according to the design. Stepped DPC must be built in to stop water penetration. The openings between the blades can be glazed with various combinations of Direct Glazing and Winvent® glazing inserts.

Sun Angles & Energy Efficiency
The diagrams below illustrate the effect of the solar control at summer solstice, spring/autumn equinox and winter solstice angles on a north facing façade at a latitude of 30° South with spacing of 5 brick courses. The Winslot® vertical components include Reveals, Mullions and Winvent® inserts, ranging in height from three to seven brick courses in 85mm increments.
