The unique solution to rain noise from ANY hard surface roof structure
The type of roof
The roofing material greatly influences the noise levels rain produces. Metal roofs are generally noisier than asphalt or tile roofs because they create a hollow, resonating sound when raindrops hit them. To address rain noise, Silent Roof is applied to commercial buildings with profile metal roofing panels, which are particularly susceptible to this problem. However, Silent Roof can effectively reduce rain noise on any hard surface roof structure.
The Slope or Pitch
The roof’s slope or pitch can directly affect rain noise intensity. Low-pitched roofs often have more noticeable rain noise because they let rain hit the surface directly rather than disperse it.
How to control rain noise
Silent Roof offers a unique solution to rain noise: it is applied to the roof’s exterior surface, intercepting raindrops BEFORE they impact the roof. It makes sense to tackle the problem at the source rather than deal with the aftermath. Silent Roof does exactly that and can be applied to any hard roof surface without permanent fixings. Adhesives of any type are NOT used. Lengths of Silent Roof Material (SRM), are laid on the roof and linked together to form an overall mat covering the entire roof surface. We secure the installation to the roof using mechanical fixings only; our installations are extremely robust and reliable in varying climatic conditions, from the wind and rain storms of the UK and Europe to the heat of the Chihuahuan Desert of New Mexico, USA. A Silent Roof installation will not compromise the roof structure. Furthermore, a Silent Roof installation can be removed without leaving a scar on the original roof surface. This can be an important factor when lease restrictions are a consideration.
Avoiding Impact Noise
Rain noise, of course, results from raindrops striking the roof surface. This is inevitable you might think. This is where Silent Roof offers a unique solution to rain noise. Instead of engineering ways to deaden the resonating sounds raindrops produce when they strike the roof, Silent Roof stops rain from hitting the roof. This is what Silent Roof does. The unique Silent Roof Material shatters falling raindrops on its smooth upper surface, dramatically reducing the noise to a whisper.
How does it work?
The smooth upper surface of the Silent Roof Material (SRM), intercepts the raindrops which are shattered silently. The water then trickles through the SRM’s complex matrix. It then drips silently onto the original roof surface and flows into the drainage system. While you can’t stop the rain, Silent Roof significantly reduces the rain noise to a whisper. With Silent Roof, you can significantly minimise rain noise on any hard-surface roof. The material is black and is UV-stabilised. Its flexibility allows it to fit any surface, flat or curved. We have developed various methods to secure the material to different surfaces without damaging the roof structure.
A technical Description of Silent Roof Material (SRM)
The solution to rain noise. SRM is a flexible, three dimensional matting, produced from polyamide mono filaments welded together where they cross to form a tough, open structure. It has a flat back on one side produced from mono filaments in an irregular, two dimensional structure which is thermally bonded to the three dimensional structure. The material is UV stabilised.
Where is it used and how is it installed
Typically used to provide a solution to rain noise on profile metal roof structures and the like. These roof structures are covered completely with continuous lengths of black Silent Roof material. Each length is secured to its neighbour and anchored at the extremities and at intermediary points across the entire roof surface by retaining wires. Because of the material’s open lattice structure, it offers very little wind resistance and is therefore unaffected by inclement weather conditions. SRM can be used over transparent roof lights which are ‘blacked out’ prior to laying the covering of SRM. The above example is typical of situations that arise within the film industry.
100% Recycleable
As the construction of Silent Roof Material is made from a single component; polyamide, it can be 100% recycled.
