My renovation was completed 3 months ago. After boiling water for 10 minutes, the pvc lining at the top hung kitchen cabinet peel off and the gum "expanded" at the base of the cabinet. I did not install a hood (did not have one in previously too). Contractor said no hood will cause heat to melt the glue and suggest to change to aluminium frame tinted glass doors and adding a stainless steel at the bottom of those sections. I did not agree as they don't complement the rest of the cabinet doors. Any expert advise on a better solution. Thank you Irene
