Transparent noise barriers - Hammerglass

CE marked noise protection solutions for roads, bridges and railways. Both the light weight and hard surface of Hammerglass make it a popular choice not only for new projects but also for glass replacements. The use of nanotechnology means that pollutants from exhaust fumes, oil and asphalt do not stick to Hammerglass as easily as they do to ordinary glass. The estimated lifespan is more than 40 years. Hammerglass noise protection systems are installed on bridge railings and traffic dividers, as well as on roads and railways in Sweden, Norway and Finland.

Our solutions are CE marked

Noise barriers at the roadside must be CE marked according to EN 14388 - regardless of whether they are made of wood, aluminium, glass or plastic. The only exception to the CE marking requirement are crash barriers built on site from loose timber. If, on the other hand, the elements are manufactured in a factory, the screen must be CE marked. However, the fact that a screen is CE marked does not automatically mean that it is a high quality product or that it meets the requirements that the customer wants to meet. The point of the CE standard is that it should be easier to set requirements since all products have been tested or calculated to the same standard. However, the requirements must be specified in such a way that they make sense in relation to the delivered product. Hammerglass noise barriers are CE marked according to applicable standards.

Reduce noise

The effect of a noise barrier depends on the height and thickness of the wall on the one hand and the speed of the passing vehicles on the other. An effective noise barrier is 4-6 meters high. We can assist you with acoustic calculations to determine exactly how high a particular wall should be based on local conditions. To increase the noise-reducing effect, the hammerfoam absorber can be installed in combination with hammerglass.

Posts and fastening systems

Hammerglass har en bred portfölj av stolpar och infästningslösningar anpassade efter hur skarmen skall placeras och monteras. Stolparna kan förankras in broäcken, på plintar eller på mur - och hållfasthetsberäknas utifrån höjd och lastpåverkan.

Hammerglass panels are usually 12 mm thick. Before the panels are cut to size, each section of the noise barrier for glazing is measured individually, making it possible to produce walls that follow the contours of the floor. This means that the noise protection wall does not have to be graded if there are differences in height. The height and design are tailored individually for each project.

If necessary, the panels are fixed with wire or through-bolts. The panels can also be patterned - usually opal or black - to prevent collisions with birds.

NOISE ABSORBING HAMMERFOAM

Hammerfoam is a complete noise absorbing system for installation on bridges or walls alongside roads or railways.

The system is based on a fully assembled Hammerglass floor or bridge solution and is complemented by a highly absorbent mat attached to the Hammerglass plate is clamped. The hammerfoam is attached to the side facing the railway track or the roadway. The vandal-proof Hammerglass plate is attached to the outside of the barrier, which is also sunk approx. 20 cm into the ground. Hammerfoam can also be used in combination with other materials - e.g. B.painted decorative panels - can be used as noise protection, such as the 400 m long weather protection at Rosengård station (Malmö, Sweden)

Hammerfoam is flame-retardant, UV-resistant and non-aging. It also resists chemicals and pressure washers used to remove graffiti. Hammerfoam does not absorb water.

SYSTEM MARK-2

A complete CE marked system with screw assemblies for installation in the floor or on walls, along roads or rails. Can be supplied up to 6 meters high.

Hot-dip galvanized square posts with a base plate for floor mounting. It can be installed on retaining walls or with ground anchors. The Hammerglass panels are clamped between an HFRHS post and a heavy duty clamp profile and secured with wire at the top if required. The Hammerglass panels are mounted on the inside of the posts (facing the street).

When mounting with bolt groups in the ground, it is advisable to bury the panels to a depth of approximately 20cm to ensure transmission to prevent noise under the barrier. For mounting along railway tracks, all shields are provided with ground bars and each section is grounded separately. A 45-degree bend at the top of the Hammerglass panels reinforces the structure while helping to effectively reduce low-frequency train noise. The Hammerglass plates can also come with patterns printed on them to prevent bird collisions.

SYSTEM BRIDGE-2

A complete system for mounting on bridge piers alongside roads or railways. Can be supplied up to 6 meters high.

Hot-dip galvanized posts for side mounting on bridge posts. The Hammerglass panels are mounted on the outside of the posts using an external backing plate and clip profile. If necessary, the panels are secured at the top with wire. The assembly is carried out from the inside of the bridge.

For assembly along railway tracks, all shields are provided with grounding rails and each section is grounded separately. A 45 degree curvature at the top of the Hammerglass panels reinforces the structure while also helping to effectively reduce low-frequency noise from trains.

Hammerglass panels can also be supplied with printed patterns to reduce bird collisions to prevent.

SYSTEM BRIDGE-3

A complete, CE marked system for mounting on a bridge to the side of the bridge girder alongside roads or railways. It can be supplied up to 6 meters high.

Hammerglass panels are clamped between an HFRHS post and a heavy duty clamp profile and secured with wire at the top if required. Normally the canopy is angled outwards to get the working width of the roadblock.

For mounting along railway tracks, all shields are provided with ground bars and each section is grounded separately. A 45-degree curve at the top of the Hammerglass panels reinforces the structure while helping to effectively reduce low-frequency train noise.


The Hammerglass panels can also be supplied with patterns printed on them to prevent bird collisions.

TRANSPARENT NOISE BARRIER WALL WITHOUT POSTS

Visibility without noise! Hammerglass' new CE-marked noise barrier, to be used in the Stockholm bypass area, is self-supporting. By bending the Hammerglass panels where a pole should be, the screen itself becomes so rigid that a steel pole between the glass panels is not required.

The barrier is designed with thin strips against bird collisions that cannot be seen from a distance but are still registered by birds. The result is an almost invisible noise barrier!

SECURITY FITTINGS

Depending on the location and design of the noise barrier, Hammerglass panels may need to be secured to prevent them from tearing out of their fixtures, tension in the wall and birds flying into the panels.

  • Hammerglass plates are secured with wire at the top
  • When installed next to the track, each shield is grounded with a separate ground bar
  • The curved top provides a high degree of stability and is often used along railway lines where high pressure is exerted by passing trains.
  • Printed patterns prevent bird collisions
  • Design and assembly
