Timber Top Fixing Methods

With Top Fixed methods, the balustrade is attached to the top surface of a substrate. With the Aluma and Eclipse Vogue series, a baseplate is structurally attached to the base of the posts, which in turn is fastened down to the substrate. This method mostly gives the strongest connection to the substrate and gives a tidy appearance when looking towards the building.

Bullet Point FIXING METHOD 4.11.1 (for ALUMA and ECLIPSE VOGUE Balustrades)

TOP-FIXED TO TIMBER EDGE JOIST AND NOG AT 90mm CENTRES

The recommended high strength and economical method of Top Fixing for a timber deck. This method requires an internal nog to be placed at each post position. The fasteners are at 90mm centres, centred on the Edge Joist and nog.

Bullet Point FIXING METHOD 4.12.1 (for ALUMA and ECLIPSE VOGUE Balustrades)

TOP-FIXED TO DOUBLE (90mm) EDGE JOISTS

With fasteners at only 65mm centre’s, this method does not require additional nog’s to be placed. However, it is not as strong as specification 4.11.1, and therefore posts may need to be closer together.

Timber Side Fixing Method

With Side Fixed methods, the balustrade is attached onto the outside face of a deck or patio and is the most common method for decks that have a waterproof membrane on them. Additionally it does not use any of the deck space, which can be an important consideration on narrow decks and access ways.

 

Bullet Point FIXING METHOD 4.17.1 (for ALUMA and ECLIPSE VOGUE Balustrades)

SIDE-FIXED TO 90mm TIMBER EDGE JOIST WITH SCREWS

This method provides a stronger connection of the balustrade to the deck than method 4.16.1, as it allows for additional thread engagement of the screws into the double timber joists.

Bullet Point FIXING METHOD 4.18.1 (for ALUMA and ECLIPSE VOGUE Balustrades)

SIDE-FIXED TO TIMBER EDGE JOIST WITH BOLTS

Bolts provide greater strength than screws when side fixing to timber. However installation may be more difficult and it is imperative that full access to the inside of the Edge Joist is maintained to enable nut placement.

Proprietary Fixing Methods

Being specialist manufacturers of balustrade systems, Unex Systems have developed two innovative and propietory fixing methods for attaching framed and semi-frameless balustrades to decks.

Bullet Point FIXING METHOD 4.17.6 (for selected ALUMA and ECLIPSE VOGUE Balustrades)

THE #DKF BRACKET
AN INOVATIVE SYSTEM FOR SIDE-MOUNTING BALUSTRADE POSTS, WHERE THERE IS A DRIP-EDGE & WATER-PROOFING REQUIREMENTS.

fixing method image

Decks with water-proofing requirements typically require the balustrade to be side-mounted, with the posts supported out beyond the drip edge as illustrated in E2/AS1. Some of the technical advantages of this #DKF system are as follows:
a. The balustrade post can be leveled vertically without the need to use conventional shims & packers. Therefore, leveling of the posts does not risk interfering with any sealing process.
b. The larger substrate bearing area of the #DKF bracket significantly reduces the risk of crushing the cladding, when the balustrade is withstanding high-lateral loads.
c. The length of the substrate fastener does not need to allow for the thickness of the post and spacer. This can be particularly beneficial where the fastener length needs to allow for cladding and cavities etc.

Bullet Point FIXING METHOD 4.17.9 (for selected ALUMA and ECLIPSE VOGUE Balustrades)

THE #DKG BRACKET
NOW ARRIVED… THE #DKG BRACKET – AN INNOVATIVE SYSTEM FOR MOUNTING BALUSTRADE POSTS, WHERE THERE IS WATER-PROOFING REQUIREMENTS AND AN EXTERNAL GUTTER

Unex Systems has recently released the new #DKG gutter bracket, which enables the balustrade to be neatly side-mounted to the outside face of the deck where a drip edge and an external gutter exist. This has long been a common problem area for building designers, as many prefer an external gutter rather than an internal one. Combining an external gutter with a side-mounted balustrade was almost impossible…until the #DKG Bracket was launched!

Glazing Channel Fixing Methods

Bullet Point FIXING METHOD 4.111.1 (for ARENA Balustrades)

#AZM CHANNEL TOP-FIXED TO TIMBER

This method is used to attach the Arena #AZM Channel to the top surface of a timber substrate, for Panorama and Metropolis styles. Note, that a continuous 90mm wide members are required, which should be structurally attached to the supporting structure to provide a stable substrate.

Bullet Point FIXING METHOD F.16.01.AZS (for ARENA AZS® Balustrades)

ARENA AZS® SIDE-MOUNT CHANNEL TO 135mm TIMBER EDGE JOIST WITH SCREWS

This method is used to attach the Arena AZS Side-Mount Channel to the side of a 135mm thick timber substrate upstand, with a central row of fixings.
