Narrow Frame Integrated Mesh Thermal Break Aluminium Casement Window Crafted for modern European minimalist residential refurbishment, our narrow sightline casement window integrates 304 stainless invisible security fly screen inside the casement sash, eliminating cumbersome extra outer screen frame to maintain smooth, streamlined exterior facade, widely preferred for mid-rise apartment and townhouse replacement across UK, Germany and Australia.

We adopt thickened 6063-T5 extruded aluminium profile with multi-cavity PA66 thermal break strips, paired with argon-filled Low-E double insulated glass. Authoritative EU testing proves its U-value reaches 1.05~1.2W/㎡K and STC 36dB soundproof performance, helping homeowners slash around 32% of annual air-conditioning and heating bills. Qualicoat certified matte black powder coating withstands 500-hour salt spray corrosion, stable for over 15 years in coastal salt fog climate. German-grade stainless hinge delivers smooth long-term outward swing, fully compliant with EN air/water tightness & PAS24 anti-intrusion standards.
