About ARK Engineering & Solutions

We have been the leading provider of premium uPVC, aluminum doors & windows for the last 14 years. We are known under the brand name of -Squares doors & window systems- - An associated company. We wanted to leverage our rich experience of delivering 1.2 million windows and serving 2500+ clients to create a sustainable green door that would be the best replacement for a traditional wooden door. We wanted the product to be a combination of supermaterial properties that are often missing in a wooded door without losing the best part of the wood which is its natural beauty. After extensive research and trying several options, we finally found our answer - -Knock Knock- -Knock Knock- is our latest offering in the premium doors segment. ARK Engineering is the parent company that holds the brand -Knock Knock-.
