The installation info could be made more detailed, plus to explain it is best for two people to participate in installation. The wood frames are pretty tough, getting the supplied screws to penetrate the wood (manually) is tough.
Ordered GPL MK08. Should have discerned that the order form said GPL M08, a smaller unit than that required. Little help after this point. Better ordering process required.
The design of the products is very impressive. Very attractive yet very functional and easy to install. We were so impressed we asked our architect to visit and see for herself.
Highly recommend this company for their proficient services and guidance at customer services. They were extremely helpful providing me with all the information required where I had inherited their product and needed specific information concerning blind replacements plus air vent part. I was then sent two variation samples that I could view ahead of placing an order for me to choose from. Marvellous help thank you kindly
