Pyramid foam - what you should know about it
Not all pyramid foams are the same - and the differences in quality are often not immediately apparent to the customer.Before you buy, please read our guide on foam quality and also the guide on egg-box foam or pyramid foam to find the right article for your application.
Pyramid foam is mainly used to absorb sound within a room or to optimise acoustics. The mats can significantly reduce sound reflections from walls and ceilings and also reduce noise and reverberation in the room, which has a positive effect on the acoustics of the room.Just like egg-box foam, eliminates reverberation and supports direct sound.Pyramid foam is not a particularly strong insulation with regard to the outside – if you want effective insulation to the outside, it is best to use our or our 3-layer "sandwich" design: composite foam, bitumen, then composite foam once again.
For example, if your problem is the insulation of ceilings and walls, take a look at our online guide.In other respects, pyramid foam can be excellent for sound absorption within a room.The thicker the foam selected, the better you can dampen low frequencies (e.g. bass).
Pyramid foam is used to reduce reverberation
Unfortunately, sound insulation and sound absorption are often confused.With pyramid foam you can dampen sound - i.e. reduce reverberation and noise in the room.On the other hand, there are acoustic foams with a considerably higher weight, which are used especially for sound insulation - these include, for example, our composite foams.It is important to know this difference, otherwise you might spend money on your project for nothing.
We are always wondering why there are so many self-proclaimed "specialists" who sometimes spread false information on the Internet.We do not like to think bad of people, and so we assume that it is simply ignorance.With pyramid foam, you attenuate the reverberation - so you can significantly reduce disturbing reverberation in the room.The more sound absorbers you use, the less reverberation you will have in the rooms.If you are looking for products for sound insulation, then visit our category "Sound insulation" of the same name - where you will find suitable products to effectively reduce noise.There you will also find many other guides that will help you to define your requirements.
How to install pyramid foam
Foam is usually a very light material.Pyramid foam is also very light - the material consists mainly of air, due to the small pores.Installation is therefore very simple.Usually these acoustic foams are glued.You will find on our pages both non-adhesive panels and self-adhesive panels.For non-adhesive foams we offer adhesives – e.g. spray adhesives or assembly adhesives.
The adhesive is simply applied to the back and the panel is then pressed against the wall or ceiling – job done. In the case of self-adhesive panels, simply peel off a protective film on the back and stick the panel up. The adhesives adhere to almost all dust-free and dry substrates. In addition, our adhesive is almost odourless, so that you do not have to worry about any odd odours in the room. And because we produce everything in Germany and test the raw materials, you can be sure of consistently high quality.Please also refer to the guide "Installing foam" for further installation options. Compared to egg-box foam, pyramid foam has the advantage that the pyramids are flush with the edge of the foam panel.
Here is an example. You can't see where one foam panel ends and the next one begins. In this way, pyramid foam can be laid end-to-end and a harmonious overall appearance is created – contained within itself and aesthetically pleasing.
The acoustic properties are virtually identical to those of egg-box foam. However, egg-box foam is cheaper because the production process is not quite as complex and the machine running times are shorter. And in addition to the foam quality or panel thickness, the machine running time is also critical for the final price. The number of customers using pyramid foam or egg-box foam is very balanced, as both materials reduce reverberation very well and the appearance is indeed a matter of taste.
Many customers find the lower price of egg-box foam to be more important, while other customers value having a more uniform installation pattern. Some find the round shape of the egg-boxes more pleasing, others prefer the pointed pyramids. So it is a question of appearance as to whether you choose pyramid foam or egg-boxes. For room acoustics, both variants are virtually identical, as already mentioned.
Which colour is the right one?
We offer various colours. Please note the following points when making your selection:
1) Light colours also make the room brighter. A dark pyramid foam always absorbs light too. If you are not covering up very much, however, you can neglect this point – also if you have a room flooded with light: the colour has correspondingly less effect.
2) Normal white PU foams usually turn yellow after a few days. PU foam reacts with the oxygen in the air and with daylight (UV radiation) – a previously beautiful white foam that turns yellowish and unsightly within a few days. Such foams can often be found very cheaply on the Internet, but since customers are frequently dissatisfied with these foams, such articles are not included in our range. Do not buy such "scrap foams" – otherwise you will end up paying twice.
For this reason you only will find on our website pyramid foams of white colour made of Basotect – this is a special sound absorber that does not yellow.The price is higher, but you get a high-quality acoustic foam that won't annoy you in the long run.
3) Coloured foams give a more relaxed spatial appearance overall. For this reason, we have also included coloured or bright pyramid foam in our standard range in response to numerous customer enquiries. We also manufacture our bright pyramid foams with Micropor quality. This allows nice patterns to be created on walls or ceilings which are harmoniously matched to the room in terms of colour.
