Double-Hung windows have two operating sash that move up and down allowing for ventilation on the top, bottom or both. Single-Hung windows allow ventilation through a single operable lower sash. Both offer easy cleaning from inside your home and remain flush with the wall. Using single or double hung windows is the best option when windows are located in a close proximity to an exterior walkway or porch area since the operation remains flush with the house in contrast to awning and casement windows. Grove Window Supply can help take this into consideration and ensure the most practical operation is being used for each window and all egress requirements are being met in bedrooms.
