Van Dam says he's a fan of all-wood windows from Kolbe & Kolbe because “the wood is a good low-maintenance alternative to aluminum.” Available in casement, awning, double-hung, and slider styles, the windows' exterior components are immersed in a life-prolonging preservative treatment before assembly.
