PUR Foam Materials

PUR (polyurethane) foam materials are specialized chemical products used primarily for filling, insulating, and sealing gaps in various construction tasks. You can apply them to door and window frames, holes in walls, or around pipes. They expand immediately upon contact with the air, perfectly covering the gap and offering excellent thermal and acoustic insulation in your home or on the construction site.

The final choice depends entirely on how you prefer to work and how often you plan to use it. At Geosantro, you will find foams like the "S-LINE HAND. 700ML", which is extremely easy to use by hand and ideal for occasional small jobs around the house. On the other hand, gun foams (like the STREET FIGHTER 750ML) offer much greater precision and speed, making them perfect if you are a professional or have a large area to cover.

A low expansion foam, like the S-LINE 750ML available in our e-shop, expands in a completely controlled manner and much less than regular foams. It is the ideal choice when you want to fill narrow gaps around sensitive materials, such as door and window frames. Because it doesn't expand uncontrollably, there is absolutely no risk of it applying too much pressure and warping or bending the frame while it dries.

B1 polyurethane foam is a highly specialized product that offers exceptionally high fire resistance and significantly slows down the spread of fire. It is absolutely essential in constructions with strict fire safety regulations or in sensitive areas where cables and pipes pass through in public buildings. Although it has a slightly higher price, it provides maximum safety and peace of mind in the event of a serious fire emergency.

Keep in mind that once polyurethane foam is completely dry, it is very difficult to remove. To make your life truly easier, we offer the "Purlogic Polyurethane Cleaner 500ml". You can use it immediately after applying the foam to clean your gun inside and out, as well as to easily remove fresh, uncured foam stains from surfaces, your tools, or even your work clothes.

Yes, proper and careful preparation always ensures much better results. First, you must thoroughly clean the surface of dust, dirt, and oils before you start. A very useful little secret used by professionals is to lightly spray the area with water before applying the foam. This moisture helps the foam expand correctly, stick even better to the application area, and dry much faster and more evenly.
