Rationel Windows are a Danish manufacturer of high-tech timber windows. These made-to-measure products are crafted from independently certified sustainably sourced materials for a natural finish that looks simply stunning.
Weather Resistant Design
Rationel Windows are weather resistant and water-tight – which makes them perfect for our Great British weather! Able to withstand extreme wind speeds of 27m per second (similar to that of a hurricane!) and 600 litres of water without leakage or damage, these extensively tested timber windows are built to last a lifetime even after being opened and closed over 20,000 times!
Safe & Secure
Alongside their durability, Rationel timber windows are designed with security in mind. Each model is tested in accordance with several national and European safety standards. Rationel windows are carefully crafted with a laminated pane and security receiver with countersunk screws fixed into the sturdy part of the frame. The hinges are also reinforced with extra-strong security angles, which prevents the sash from being pulled out of the frame – a great deterrent for even the most tenacious of thieves!Enquire about this product
