Before embarking on any project involving expanding foam, preparing your workspace and adhering to safety guidelines is essential. This ensures not only the success of your project but also your well-being throughout the process. 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. Ensure the stability of the frame in the opening, preventing flex and operational issues with windows and doors once installed Avoid overfilling, as the foam will expand. Overfilling can lead to unnecessary waste and a messy finish. Minimally expands 5-10% only on application putting minimal stress on the timber window or door frame.

Is waterproof; weather and mould resistant ensuring water runoff and will stay looking clean long after occupancyFire-resistant foam is designed to slow the spread of flames, making it an essential material for fire-rated construction.

To secure your window and prevent any leakages, you’ll need to seal your timber windows. Exact Gap Foam High-density polyurethane foam, such as the Everbuild Professional Gun Grade Expanding Foam, is particularly suitable for larger gaps and cavities due to its robust expansion properties. On the other hand, low-density polyurethane foam is ideal for smaller, more delicate applications. Remember, practice makes perfect. The more you work with expanding foam, the more skilled you'll become at applying it. So, don't be discouraged if your first few attempts aren't perfect. Keep practising, and you'll soon master the art of applying expanding foam. Everbuild exact gap foam is also the product to use where it is important not to impact too much stress onto the item being installed i.e. deforming plastic frames. Cured foam can often present more difficult problems than uncured. If you have cured foam on a surface that has hardened then you may need some tools to remove it.Controlling the flow of expanding foam is crucial for a successful application. Here are some tips to help you achieve a consistent flow: Remember, safety and preparation are paramount when working with expanding foam. By following these guidelines, you can ensure a safe and successful project. Polyurethane foam is resistant to water, chemicals, and pests, making it a durable and long-lasting solution for various projects. Whether you're sealing gaps, insulating spaces, or fixing leaks, our in-depth guide to expanding foam has you covered. Discover the different types of expanding foam, learn how to use them correctly, and gain valuable insights into their properties and limitations. 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.

Gives excellent adhesion to all common building materials, porous and non-porous without the use of primersIf you are fitting windows into a cavity wall, you must ensure that cavity closers are used. They help prevent heat loss and issues with mould, damp and even water ingress. Proper cleaning and maintenance of your expanding foam tools are crucial to ensure their longevity and optimal performance. This section will provide practical tips and best practices for cleaning up spills, unclogging nozzles, and maintaining your foam gun. We would always recommend that DPC is fitted to the underside of your timber window, no matter the fitting situation. Spacing your timber window

Canister may be transported / stored in horizontal as well as vertical position. For more industry guidance on installing timber windows and doors, explore our helpful guides here. What materials do you need to install a timber window?

Sealing between the window/door frame and the wall is paramount to prevent air and water ingress for compliance with Part C and L of the UK Building Regulations. Another common cause of operational issues in windows and doors post-completion is the overuse of expanding foam. Expanding foams fill the gaps, but they can expand too much in this situation, putting pressure on the window or door frames and potentially causing them to bow. Benefits of Everbuild Exact Gap Foam: If you do not have your windows installed by a FENSA or CERTASS certified installer, then you will need to pay for a Building Control Body to come out to inspect, and if they are satisfied, sign off your windows. For an extension, new build, or newly formed window or door opening, FENSA does not apply and you will require approval from Building Control. How do you install timber windows?
