Ensuring that your home remains snug and warm during the colder months while staying cool and ventilated during the summer isn’t just a matter of comfort — it’s also about efficiency. This category is meticulously curated to address the critical points where heat often escapes. Namely, the windows and doors with our selection of professional accessories, including thermal window sills, window foundation solutions, and various window tape options, creating an energy-efficient barrier against the elements has never been easier.

Our thermal window sills are designed to integrate seamlessly with your window installations, providing a robust solution that enhances the aesthetic appeal of your windows and notably reduces thermal bridging. This critical component is often overlooked, yet it plays a significant role in maintaining the thermal integrity of your home.

For the foundation, our range includes solutions that are engineered to prevent heat loss at the base of your windows. It’s a common issue that can lead to increased energy consumption. These foundation accessories are an essential part of creating a comprehensive insulation system for your home.

The selection of window tapes, including window flashing tape, window seal tape, and window insulation tape, offers various options for creating an airtight and water-resistant seal around your windows. These tapes are crucial for preventing moisture intrusion and air leakage, which are two of the primary culprits behind energy loss in homes. Easy to apply and highly effective, our window tapes are an indispensable tool for both DIY enthusiasts and professional installers.

At Fenbro, we understand the importance of selecting the right windows and doors and ensuring they are installed with precision and care. Our accessories are designed to complement our range of high-quality windows from Poland, ensuring that your installations are both visually appealing and thermally efficient. Whether you’re undertaking a new build, renovation, or simply looking to improve your home’s energy performance, our accessories provide the solutions you need to achieve your goals.

Frequently Asked Questions

Naturally! If you wish, you can arrange transport by yourself.

Yes, you can! Additionally, we offer support after the guarantee period is over. It means that if something happens with your joinery afterwards, we can get you all the necessary spare parts, ready-made products and tools to help you solve the issue (the service is chargeable at the end of the guarantee period).  Please note that if you choose your own fitter, you are responsible for providing them with correct measurements of the openings as well as products dimensions. We cannot be held responsible for any irregularities in this regard.

You can contact our customers at FACEBOOK (check the reviews) and see the pictures they sent us. Unfortunately, we cannot share any of our customers details (like their address, etc.) with you. Our privacy policy doesn't allow us to do any of that . But still, you can contact those customers who left their comments on Facebook on your own. Additionally, on our website, there is a section where you can see some of our realizations in Ireland. For customers in Ireland: If you wish to see our windows, our fitter (based in Ireland) has all models: samples and colour samples as well. When you are ready with the order, he will bring the samples for the final measurements meeting.

Your house plans are not necessary for us to prepare the quote for you. It would be much more efficient for us to have the list of your joinery together with the following details:

  • Width x height [mm]
  • Colour
  • Glazing: double/triple
