WHAT OUR CLIENTS SAY…

For my project’s casement windows and doors Rationel was a clear winner. Their double glazed windows easily met my U-value requirements. They offered good security and excellent weather resistance. Outward opening casements were essential due to the oak braces and fixed glazing. I wanted a window that offered a blend of traditional and contemporary styles. The Aldus window and door range from Rationel was perfect for this. The Aldus is constructed from a substantial treated softwood frame and uses simple Scandinavian style window furniture. Externally the window is clad in aluminium giving a sharp modern look and significantly reducing the need for external maintenance. The aluminium window cladding allowed me to have different colours internally and externally. I found my local Rationel distributor Landmark Windows to be extremely helpful throughout. They provided a high level of customer service before and after delivery.

We would like to thank Landmark and in particular yourself for your excellent level of service from initial enquiry through to after care. We found you via the Rationel website. Landmark being identified as their local dealer in our area. As self builders we had to rely on the expertise of others throughout the build and when it came to the Windows both Liz and I were glad it was you. We were initially impressed because you took the trouble to take us to the Regional showrooms to review the product. You helped us understand the finer details of design choice, cost and effectiveness. Liz and I are both grateful that you have been as enthusiastic as us to help achieve our goal. From our perspective, collaboration with key suppliers and expert advisors has been critical to success. Your contribution and the Rationel product should not be underestimated in terms of overall impact on our project. Kind regards Liz & Ray
