It shoots liquid foam deep into cavities, creating a long lasting seal, which insulates against heat, sound and moisture. Suitable for inside or out, it can be easily trimmed and sanded ready to be painted, filled or plastered.

No waste foam cans incorporating a unique internal valve system that means part used cans, can be saved and used again and has a longer shelf life compared with most conventional expanding void fill foams the unique safety valve will not clog or leak.The materials required to install timber windows will depend on the exact fitting situation and the type of building/ opening into which you are installing the window. Minimally expands 5-10% only on application putting minimal stress on the timber window or door frame.

Polyurethane foam is a popular choice for insulation and sealing applications due to its excellent adhesion to various surfaces. It comes in high-density and low-density options, allowing you to choose the right one based on your needs.Respirator or Mask: Ensure proper ventilation and prevent inhalation of potentially harmful fumes. The Silverline P2 Valved Safety Face Mask Dust and Mists is an excellent option for this. The range of products we actually manufacture is extensive, from chemical blending for admixtures and water proofers through water based sealant manufacturing to the highly advanced polymer engineering undertaken in manufacturing silicone and hybrid sealants and adhesives and a wide range of powder products. Its lower toxicity makes it a safer option for indoor applications. The Everbuild Exact Gap Expanding Foam is a good example of a latex foam product that provides a controlled application with minimal expansion. No waste hand held foam uses a unique straw applicator that much more comfortable and controlling than a standard foam straw these straws are also available separately. Avoid overfilling, as the foam will expand. Overfilling can lead to unnecessary waste and a messy finish.

Using the right tools is key to a successful project. For applying expanding foam, consider using the Bond-it Pro AG1 Expanding Foam Applicator Gun. It's designed to provide precise control, ensuring the foam is applied exactly where you need it. After use, the Soudal PU Expanding Foam Gun Cleaner Trade Red Tin can help keep your applicator gun in top condition, ready for your next project. In some cases, the expanding foam may overexpand and land in areas you didn’t want, whether that is another part of the surface or your clothes or hands. The reaction and speed of action you take depend on the type of expanding foam that you use. For example, latex-based expanding foams are more flexible as they dry and therefore you can clean them when uncured with soap.

Cleaning and Maintenance

Other expanding foam filler options include precise products with limited expansion and reduced-waste solutions designed to last longer than conventional foams. Start at the lowest point and work upwards. This allows the foam to expand upwards and fill the gap evenly.
