Ventilation grilles

Neaco modular grilles are ideal for ventilation applications, from ground floor ventilation grilles to upper floor ventilation and ceiling ventilation grilles. Unlike many metal grating products, our systems are available a range of profiles which vary in terms of surface area percentage, thus offering different levels of ventilation according to choice. For example, the Neatdek ‘T’ bar profile provides a 74% surface area for applications requiring a lower degree of ventilation, in contrasts to the Flat Bar profile which maximises ventilation with greater space between grille bars providing more airflow.

KEY PERFORMANCE FEATURES

Patented swage-locked construction between the bars enables high structural efficiency.
Corrosive-free for maintenance-free durability, with a design life up 120+ years.
Engineered for slip-resistance which can be further enhanced with optional serrated surface.
Manufactured from A1 Fire Rated aluminium

Grille Profiles

Flat Bar

Flat BarUtilising a proven design concept, our Flat Bar system provides a lightweight, economical solution.

Flat Bar is available in two standard thicknesses, but can be application engineered to meet bespoke requirements.

Fire Rating: Zero fire rated
Surface contact area: 10.6% (3mm Flat Bar) or 16% (5mm Flat Bar)
Materials used: load-bearing bars in Aluminium Alloy 6082 T6 & swage bars in Aluminium Alloy 6082 T4
Recycled content: 85-100% (finished product is also 100% recyclable)
Ni Bar

Ni BarN-I Bar’s ribbed surface makes it an ideal choice for environments in which non-slip qualities are important.

Fitted in the same way as Neatdek and Flat Bar, N-I Bar boasts a high strength-to-weight ratio and a particularly attractive appearance.

Fire Rating: Zero fire rated
Surface contact area: 21%
Materials used: load-bearing bars in Aluminium Alloy 6082 T6 & swage bars in Aluminium Alloy 6082 T4
Recycled content: 85-100% (finished product is also 100% recyclable)

Neatdek

Neatdek

Neatdek pioneered the concept of open and closed construction with an innovative ‘T’ bar profile with minimal gaps (widths of 5mm or 8mm) between bars.
The system is available with a plain surface or a specially engineered anti-slip surface. It can also be cambered slightly to assist drainage.

Fire Rating: A1 fire Rated and fully compliant with Class 0 of Part B
Surface contact area: 74% (8mm gap Neatdek) or 84% (5mm gap Neatdek)
Materials used: load-bearing bars in Aluminium Alloy 6082 T6 & swage bars in Aluminium Alloy 6082 T4
Recycled content: 85-100% (finished product is also 100% recyclable) Free air rate 25% (8mm gap Neatdek) or 16% (5mm gap Neatdek)
Serrated Options

Serrated OptionsTwo of our ventilation grille profiles – N-I Bar and Flat Bar – are available with serrated options to provide sure footing in hazardous conditions with an anti-slip surface.

Serrated N-I Bar achieved the highest slip resistance in independent testing.

Fire Rating: Zero fire rated
Surface contact area: 21%
Materials used: load-bearing bars in Aluminium Alloy 6082 T6 & swage bars in Aluminium Alloy 6082 T4
Recycled content: 85-100% (finished product is also 100% recyclable)

FEATURES & BENEFITS

STRONG & DURABLE

STRONG & DURABLENeaco ventilation grilles feature our patented swage-locked construction which provides high structural efficiency. The system is lightweight (1/3 of the weight of steel) yet high in load-bearing capacity for ground-level ventilation which is subject to pedestrian traffic.

The grilles retain a high residual value and the aluminium is fully recyclable. Aluminium is extremely durable and has a design life up 120+ years.
MAINTENANCE-FREE

MAINTENANCE-FREEAluminium is corrosion resistant, so unlike other metals it will stay rust-free. Its maintenance-free qualities give it a clear advantage over other materials which get damaged by weathering and temperature fluctuations.

Aluminium retains its colour extremely well, unlike GRP which is prone to bleaching with prolonged exposure to sunlight. Aluminium’s absence of moss and lichen is another clear advantage over GRP.
FIREPROOF

FIREPROOFIn the BS 476 Fire Test Series aluminium is rated 0 (the highest possible) in the categories of Non-Combustibility, Ignitibility, Fire Propagation and Surface Spread of Flame. In the EU’s harmonised Euroclass system, aluminium has an A1 Fire Rating – the highest achievable score for non-combustibility.

Neaco’s ventilation grilles are manufactured from aluminium and have been fully tested to comply with the requirements for Class 0, as defined in Approved Document B, ‘Fire Safety’, to the Building Regulations 2000. These performance levels make Neaco’s ventilation grilles the stand-out choice to satisfy fire safety requirements.
ECO FRIENDLY

ECO FRIENDLYAluminium’s natural attributes are ideal for sustainable development. It is non-toxic, corrosive-free and has an extremely high residual value.

Aluminium is 100% recyclable with no downgrading of its properties and very little energy required for re-melting. It can be recycled over and over again without loss of performance – there is no difference in quality between virgin and recycled aluminium alloys. It can also be up-cycled if necessary. Its lightweight handling also saves on manpower.
SAFE UNDERFOOT

SAFE UNDERFOOTThe working qualities of aluminium make for ease of fabrication. This has enabled Neaco’s design team to incorporate anti-slip surfaces into our ventilation grille systems for ground-level installation which is subject to pedestrian traffic.

The resulting slip resistance is another quality which makes the products safer than other materials, which eventually become slippery underfoot. In addition to ribbed surfaces, we also provide serrated options to further increase slip resistance.
EASY INSTALLATION

EASY INSTALLATION All Neaco ventilation grilles are designed to be fast and easy to install, minimising time on site. Panels are 1/3 of the weight of steel for easy handling.

The panels are fitted without welding, providing low-energy construction which eliminates mess, noise, pollution and waste. Neaco can supply a team of fitters and we also offer full technical support for your construction and installation requirements.
