I contacted Origin to recommend an installation partner who could carry out a 3 panel bi-fold door install for us. We selected Panoramic Door Company as recommended by Origin who are a recommended supplier. Panoramic promised the world and kept delaying the install dates with 4 delays in total. Further Panoramic had to make 3 visits to complete the work due to glass not arriving, then the glass panels being scratched and finally to correct the mistakes made. The actual door itself has not lived up to the promise expected. We ordered a triple glazed door hoping for better thermal properties paying a premium for the door but thus far even in a mild summer it has made little difference to keep heat in. More so there is a constant draft at the hinges where the wind is able to so simply blow into the house. I am not impressed at all with the product. It might look great but from a thermal point of view its not and the suppliers carrying out the work did not deliver the service we expected considering we paid nearly £4000.
