- construction foam is often used in construction, both on large construction sites and in the home, for compacting, insulating or fixing. It is a filling foam that can be filled into cavities or used to quickly fix building materials.
- Basically, when buying construction foam, you have to pay attention to the area of application, as the composition, colour and properties of the foam vary.
- In addition, the safety instructions on the foam can must be observed. You may need to buy safety gloves, safety goggles and a protective suit.
The Best Construction Foam: Our Choices
Buying and evaluation criteria for construction foam
In the following, we present some criteria that you should look for when choosing and buying building foam. They are intended to give you a few simple points of differentiation to help you make a decision when choosing building foam.
When choosing construction foam, you can use the following criteria to compare the various choices available on the topic of construction foam:
Construction foam cans or cartridges are available in different sizes. From mini cans with 150ml to cans with 750ml capacity, everything is available. However, the most common are the 500ml and 750ml cans.
In many cases, double packs or other packages with several cans are also offered if there is a need. Together with the foam volume, the quantity will give you a good guideline for choosing the right building foam.
In addition, you can also choose the colour of the foam, which is especially interesting if you want to use it on visible areas. Basically, building foam is available in the classic colours such as white, grey and beige. But construction foam is also available in black, pink, yellow, red and green. The colour of the foam can usually be found on the can.
It is important to note the volume of foam that you get out of a can. This is very individual and should always be read on the can or asked for.
The volume can vary between 8 and 30 litres depending on the can. If you know what you are using the construction foam for and how much space you may need to fill, it helps a lot to know how much you will get out of a can.
There are also important things to consider when it comes to temperature. Here, both the application temperature and the temperature resistance play a role. Here, too, the temperatures vary depending on the type of foam.
The temperature at which building foam may be processed is between -10 and 35 degrees. Building foam is resistant to temperatures between -50 and +110 degrees. You should also take another look at the can to be sure.
Accessories for building foam are very versatile. Basically, various adapters or attachments are offered for the existing cans and guns. But special guns or so-called foam presses are also available.
For the care of these utensils, there is also a selection of cleaning agents, such as cleaning cloths or liquid cleaner from the bottle.
Guide: Frequently asked questions about construction foam answered in detail
What is construction foam?
It can be used for insulation or insulating, but also for filling cavities or for bonding different objects.
What types of construction foam are there?
One-component construction foam only hardens if the area has been sprayed with water beforehand, whereas two-component construction foam dries without water. In most cases, a so-called hardener is needed here to ensure that the construction foam hardens.
Which foam do I use for what?
Two-component construction foam is particularly suitable for filling especially large cavities, as the volume increases more quickly after leaving the can and is larger overall than with one-component construction foam
What does construction foam cost?
|Price range||Available products|
|Low-priced (3 - 5 €)||Mostly own brands from DIY stores|
|Medium-priced (5 - 10 €)||Classic foams from various manufacturers that can be used in a variety of ways|
|High-priced (from 10 €)||Special foams that have special areas of application, for example|
What does construction foam adhere to?
When is construction foam cured?
construction foam is a versatile tool that can be used by both professionals and do-it-yourselfers on the construction site. Its ease of use makes it a good alternative to conventional insulation materials in many respects.
Whether sealing joints or holes created by a pipe bursting through, construction foam seals gaps large and small. Even in combination with water, there are some construction foams that provide a reliable seal.
Most foams also provide sound and heat insulation that lasts reliably for many years. Building foam also has very good adhesive properties and is suitable for assembling a wide variety of objects.
Building foam is available in different colours and is applied either with an adapter tube or a special foam gun. These are often included with the purchase.
It is important to follow the safety instructions on the flammability of the construction foam and also the instructions for working with construction foam. In any case, find out in advance how you can protect yourself and whether you need to buy protective clothing.
