• Winblok® Screen
    the decorative solar facade

"Walls you can see through"

“Walls you can see through”, became a phrase that described Winblok® The Total Window System, the load bearing, modular concrete surround, with its attendant Winvent Aluminium glazed Window range. The introduction of Winblok® as a replacement to walls and windows helps modulate the sunlight, however presents a heavily sculpted appearance in the external façade.

The potential to ‘wrap’ the Winblok® load bearing wall with a finer ‘decorative solar’ screen on the external face; and to glaze the internal rebated face with the Winvent fixed or opening glazed inserts; presents a unique opportunity to “dress up” facades with a softer skin on the external load bearing envelope. This lends the architect an open flexibility allowing structural load, light and love; to wrap the building.

We introduce to you our latest addition to the Winblok® range:

Winblok® Screen - the decorative solar facade”

The full Winblok® Screen range

The Winblok® Screen is designed to suit the 600 x 600mm module Winblok® (WB66-260), manufactured from lightweight, high density, low permeability, reinforced, precast concrete - cast in high quality moulds. The finished product has a smooth external facing 'offshutter' finish, and an internal struck face. Winblok® Screen may be painted or left untreated and is fixed to the Winblok® frame on site with SPM40SG Neutral-Cure Hybrid Sealant.

squircle

Winblok® Squircle Screen

(WB66-SQS)

This screen, although an orthogonal grid in origin, presents as an organic ‘bone like’ softened grid, neither square nor circle, a Squircle. A softer and quieter rhythmic façade is generated in a continuous wall of these screens.

nest

Winblok® Nest Screen

(WB66-NS)

Taking a cue from the ‘Birds Nest’ Beijing Olympic building, we have designed an asymmetric fractal screen that may be fitted in a single or random orientation, generating subtle variations in the progression across the façade.

louvre

Winblok® Louvre Screen

(WB66-LS)

The louvre screen draws on the more conventional shutter aesthetic if fitted in the horizontal format. However, it may also be fitted vertically (say on east or west facades) or used to orientate the view from within in a particular direction. This screen is better suited to act as a rain screen in its horizontal format, as it has a continuous drip along the top edge.

solid

Winblok® Solid Screen - Plain

(WB66-SSP)

The Solid Screen - Plain, presents an opportunity to ‘blank out’ the facade where necessary, resulting in a standard wall panel. With its external facing, smooth off-shutter concrete finish, it creates a familiar modern concrete look.

solid

Winblok® Solid Screen - Timber

(WB66-SST)

The Solid Screen - Timber is inspired by 'timber off-shutter concrete architecture'. Timber engrained solid concrete screens, allow for blanking out the facade, with a randomly designed ‘timber off-shutter’ look. Place them vertically, horizontally, or alternatively.

The Winvent® range

Specifically designed and engineered to integrate perfectly with Winblok® Screen

winvents
winvent-top-hung

Winvent® Tophung

The aluminium Top-hung projecting out Winvent® is supplied factory glazed (silicone flush glazing). 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.
Fly screens and burglar bars may be factory fitted as additional accessories.

*Note: This Winvent Tophung does not open 100% when installed behind the Winblok® Screen. The Architect is to specify the PC colour and glass type required.

winvent-top-hung

Winvent® Dual Tophung

The aluminium Dual Tophung projecting out Winvent® is supplied factory glazed (silicone flush glazing). 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.
Fly screens and burglar bars may be factory fitted as additional accessories.

The Architect is to specify the PC colour and glass type required.

winvent-fixed

Winvent® Fixed Frame

The aluminium fixed frame Winvent® is designed to match the opening Winvent® Tophung. Manufactured from superior quality aluminium extruded sections, which are epoxy powder coated finished. As with the Top-Hung, it is supplied factory glazed (silicone factory glazing).
Burglar bars may be factory fitted as additional accessories.

The Architect is to specify the PC colour and glass type required.

directglazing

Winvent® Fixed Direct Glass

We have developed one of the most cost-effective ways to allow light into the building. A pane of toughened safety glass (TSG) (no aluminium frame) is directly installed into the glazing rebate of the Winblok® concrete frame using our SPM40SG Hybrid Sealant.

We recommend using toughened safety glass (TSG) for this application, as this minimizes 'cracking' due to movement. The Architect is to specify the glass type required.

centralpivot

Winvent® Central Pivot

The aluminium central pivot Winvent®, designed for high level applications with a pull ring spring catch, is supplied factory glazed (silicone flush glazing) and 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.
Burglar bars may be factory fitted as additional accessories. Flyscreens cannot be installed on Central Pivots.

The Architect is to specify the PC colour and glass type required.

flyscreen

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.

glazedlouvre

Winvent® Glazed Louvre

The Winvent® Glazed Winlouvre 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. It may be fixed to Winblok® with the glazing rebate on the inside or outside of the building. Glazing may be 114mm blade widths of clear or obscure glass. Glazed Winlouvres may be used for ventilation in conjunction with Winblok® Winguard or special burglar bars in high security applications.

The Architect is to specify the PC colour and glass type required.

fixedlouvre

Winvent® Fixed Louvre

The Winvent® aluminium fixed Winlouvres provide permanent fixed ventilation for squash courts, switch rooms, ventilation ducting and other similar applications. They will however not totally exclude entry of wind driven rain. Aluminium Winlouvres are manufactured from extruded aluminum louvre blades carried on tubular mullions and mounted in an aluminium Winvent® frame.
Aluminium Winlouvres may be supplied with a Flyscreen and burglar bars attached if required.

The Architect is to specify the PC colour and glass type required.

burglarbars

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.

Please contact us to order or check stock availability within South Africa.

Winblok® Screen Application

The Winblok® cross-section has a glazing rebate on one face and a sloping soffit, reveals, and sill towards the ‘struck face’. We envisage that the best application of the Screens will be over the Winblok® System where the struck face is facing the exterior and the glazing rebate is on the inside face of the building. In this way, rain water that penetrates through the Screens will run off the bottom sloping sill, towards the exterior.

It also follows that the opening Winvent® sashes may open into the cavity behind the Winblok® Screen. All the Screens are designed to fit over the face of the Winblok® - not into them. Here the Screens present a primary face with the Winblok® concrete surround, taking a secondary structural role recessed behind the Screens.

Winblok® Screen 'Retrofit' Compatibility

We have also seen the opportunity to fit Screens over Winblok® WB66-260 (590x590x260mm) in existing buildings. Only applicable where the glazing rebate is on the inside of the building and the sill, with it’s ‘struck face’ is on the outside. A cost effective way of giving a face lift and modulating the interior privacy and light.

Winblok® Screen Design Consideration

The 600x600mm module Winblok® with a 260mm depth, has become by far the most popular size in the Southern African market. We have chosen this size to be the prime carrier of the new Winblok® Screen range. In designing the Screens, we have also recognised the degree to which security, together with solar and visual screening, needs to be integrated.

Rain screening also plays an important design consideration. Concrete, notwithstanding its environmental impact, remains the robust, easily maintained material of choice if used judiciously. With that in mind we have developed a lightweight, reinforced concrete, that will last for decades. We are also able to introduce muted colours into the product using pigments as permanent tints for bespoke projects.

We assist with drawing details, specifications and pricing consideration.
