Energy efficiency

Casement windows are designed to provide a tight and secure seal when closed, which helps to reduce the amount of heat or air conditioning that can escape from the building. This helps to keep the indoor temperature consistent and to reduce energy costs associated with heating and cooling. The energy efficiency of casement windows is further enhanced by the use of double-paned glass and high-quality weather stripping.

They are constructed from high-quality aluminium, and are designed to withstand the harsh elements of nature. This includes exposure to wind, rain, snow, and sun, which can cause damage to other types of windows over time. Casement windows are also easy to maintain, as they can be cleaned and painted or stained to match the overall style of the building.

Casement style windows


Unlike other types of windows, casement windows can be opened fully, which allows for maximum airflow into the building. This helps to reduce indoor air pollution and to improve air quality, which is especially important for individuals with allergies or respiratory issues
