The Wood Door+ lauan hardwood open louvre door is manufactured out of hardwood timber & its traditional style door is ideal for use inside or outside. Some applications could be for internal cupboards or external window shutters. The open design means there is a 5mm gap between each slat, making these doors ideal to be used in areas that need ventilation; such as airing cupboards or boiler cupboards. Our lauan hardwood louvre doors are 28mm in thickness. All Wood Door+ lauan hardwood louvre doors are supplied untreated. This means they do not have any finishing coat on them, ideal for painting or staining to your required final finish.
