Can I have a catflap in my door?
We cannot supply a door with a catflap factory fitted. Any amendments made to the door may invalidate the warranty of your product.
Do you supply curtain walling?
Due to Rationel products not being CWCT certified (which is an air permeability, weathertightness, wind resistance and impact mandatory test), we are unable to supply curtain walling.
What is the equivalent area of Rationel trickle vents?
When tested through window/door frame section, the equivalent area achieved is 2224mm2. When tested through a generic board, the equivalent area achieved is 3786mm2. This figure can be applied all current Rationel window systems. Testing has been carried out according to EN13414-1.
