Bifold windows over kitchen servery / weather seal

Bifold windows have been installed in our new kitchen servery opening to the outside pergola as shown in the first picture. The windows are from Trend Windows. The gap at bottom ranges from 4mm to 6mm. There is an obvious concern of weather and insect ingress through the gap. The renovation contractor has stated that Trend offer no sealing solution in this application and was intending to leave it unsealed. There is a channel in the frame under the window as shown in the second picture. The contractor states this is not suitable for a seal installed in the channel (such as from Dooorseals.com) because of the metal plates at the end of each window panel. That is, there would be a gap in the seal at the end of each panel. The contractor’s recommendation is to use a stick on brush type seal adhered to the outer side of the channel and also covering the end plates.


Is my contractor right? Has anyone encountered this problem before and can recommend a product that would best suit the purpose.






Many thanks.
