Replacement Windows
Is time to replace your windows? There are many reasons why customers opt to replace their windows, from a weathered appearance and outdated style to a desire to enhance energy efficiency, increase home security and reduce their heating bills. Regardless of your reason, Astral Windows and Doors can provide you with guidance and advice about the right replacement windows for your home.
We supply and fit a wide range of replacement windows including uPVC windows, timber windows and Aluclad windows, and a variety of styles such as sash windows and casement windows. All replacement windows can be double or triple glazed.

Benefits of changing your windows
Replacement windows offer a vast range of benefits that can transform the look and comfort of your home. They can also mitigate heat loss and significantly increase your home’s thermal properties, with triple glazed replacement windows achieving a remarkably low u value of 0.8 compared to traditional windows with u values of between 2.5 and 3.5.
Upgrading your windows can improve the following:
• reduce noise
• reduced energy bills
• improved BER rating
• A-rated for energy efficiency
• less maintenance
• excellent air-tightness
• wide range of styles and colours
• enhanced security
• sustainable timber options with FSC Certification
Replacement windows also offer the opportunity to increase your home’s security. Our windows feature up to an eight-point locking system which creates additional intruder barriers and a more secure home.
