Link Vents (Clip in & Screw in)

Glazpart is proud to launch a new range of plastic injection moulded trickle ventilators to meet the needs of today’s building designers, window fabricators and installers.

At the FITSHOW 2013, we launch the first of the “Link Vent” range of patent applied for trickle ventilators. Developed in 2 sizes the vents performance will be 5000 EQA and 2500 EQA. Equivalent area (EQA) is used instead of free area for the sizing of trickle ventilators as it is a better measure of a ventilators air flow performance.

The vents are designed to meet the requirements of building regulations, Approved document F1 2010 (Means of ventilation) whilst delivering a product to meet the needs of today’s ventilation and window markets.

Versatility

• Meets F1 requirements for new build and replacement sectors.
• Designed for use on all window types (UPVC, Aluminium and Timber).
• 1000’s of colour decoration options, delivered in any combination or packaging requirement.

Compact

• The Link Vent 5000 EQA delivers significantly more EQA performance compared to similar overall length traditional 4000mm2 (free area) ventilators.
• The Link Vent 2500 EQA delivers approximately the same performance of a traditional 4000mm2 in the length of traditional 2000mm2 (free area) ventilators.

Efficient

• 2500 EQA is delivered through a 204 mm x 13 mm slot size, reducing routing machine times and waste materials generated. For simplicity the 5000 EQA has 2 slots of the same size.

Use of ASA in this application delivers

• Excellent UV colour stability.
• Good mechanical properties.

Clever design

• Simple, user friendly opening of the vent finishes with a positive closing action.
• The innovative “link” allows the closure plate to be positioned to reduce draughts with the benefit of directing air away from occupants.
• The Link Vent 5000 closure plate is split to allow for partial (50%) opening and further ease opening of the ventilator.
• Rounded ends of the vent allow for installation on timber windows.
• Available in either screw or clip in fixing types.
• The screw fix design eliminates the need for end caps.
• The clip fix design Pawl’s allow for a fast, easy vent installation.

1000’s of Colour options

• Standard colours: White, Dark Brown, Black and Oak Brown.
• Stock colours: Cream, Anthracite Grey, Chartwell Green.
• Wood grain print effects for Irish Oak, Golden Oak, Mahogany and Rosewood.
• Paint spraying of ventilators from our stock to ANY RAL, BS colour a colour swatch matching service is also available.

Acoustics is specialist science covering the generation, control, transmission and detection of sound and vibration. Acoustics relating to buildings is changing and moving from the suppression of noise to the design of environments which enhance health inparticular mental health.

What is a Dn,e,w sound reduction figure?

A Dn,e,w figure reflects testing at every frequency and it is the only result recommended by the BRE for products such as trickle vents.

As there is no industry standard for presenting acoustic test results, be wary of unspecified dB figures being quoted. The unspecified figure may be the highest dB achieved at a frequency and may not be relevant o your application or source of noise.

A Dn,e,w result reflects the true performance of the trickle vent.

Frequently used terms for acoustics
1Hz is one wave cycle per second, 20 Hz is 20 per second, where the cycles are 20 times shorter and closer.

A ‘frequency band’ is a continuous range of frequencies between an upper and lower limit.

An ‘octave band’ is a frequency band where the upper limit is twice the frequency of the lower limit.

A ‘one-third octave band’ is a frequency band where the upper limit 2 times the frequency of the lower limit.

Intensity of sound is measured in Decibels (dB). This is a logarithmic scale in which an increase of 10 dB doubling loudness.
