Precision Engineering & Thermal Performance

Our uPVC casement windows are built using the award-winning double glazing Profile 22 Optima system, ensuring your home remains energy-efficient year-round. Featuring a sophisticated multi-chambered profile and high-performance weather seals, these windows act as a powerful thermal barrier, eliminating draughts and cold spots. With the ability to achieve A+ energy ratings and exceptionally low U-values, they are designed to retain heat far more effectively than standard frames.

 

This precision engineering doesn't just improve your home’s comfort; it significantly reduces carbon emissions and lowers monthly energy expenditure. By choosing Allgood Construction, you are investing in a sustainable, high-performance solution that protects both your property and your pocket against rising energy costs.

Advanced Security & Structural Integrity

Security is at the heart of every casement window we install. Utilising the robust Safeguard locking suite, each window is equipped with a high-security multi-point system that grips the frame at several points, making forced entry virtually impossible. The windows feature heavy-duty stainless steel hinges and optional hinge guards to prevent jemmying, while internal glazing ensures that the glass cannot be removed from the outside.

 

Beyond security, the frames are manufactured with high-impact uPVC, ensuring they never warp, rot, or peel, even in the harshest British weather. This combination of structural strength and forensic-level security provides homeowners with total peace of mind and a product built to last for decades.
