Three internal window designs

Flush, chamfered and sculptured styling on the inside of Exlabesa KC51 windows offers three attractive window designs to work with the property style and provide a classic, seamless or profiled aesthetic. All these styles offer the same specifications in terms of insulation, security and sealing.

Available as fixed windows, side or top-hung openers or a combination of fixed and opening modules, Exlabesa KC51 casement windows offer numerous design options for standard or large window openings. Impressive opening sizes create contemporary windows up to 1500mm high or 1500mm wide for top-hung casements and up to 900mm wide or 1500 mm high for side-hung windows.

Security and Energy Efficiency

Excellent security comes as standard across our entire range of quality-made windows, and the Exlabesa KC51 is no exception. All opening casements are fitted with reliable and secure multipoint locking, operated by stylish and robust window handles. Internal glazing beads ensure the glass cannot be removed from the outside, and extensive sealing protects your home from the worst of the winter weather.  

Exlabesa KC51 windows come in insulated aluminium profiles, with U-Values as low as 1.4 W/m2K depending on the glass specification chosen and meeting current Building Regulations. In addition, the entire system is tested to the latest standards for air, wind and water protection.

Personalisation Options

The insulated aluminium profiles come with an additional thermal upgrade, using advanced foam strips and further increasing the thermal performance of the windows. A full range of RAL, BS or Syntha Pulvin colours protect Exlabesa KC51 windows and offer a low-maintenance new aluminium window.

For your glass, there’s a complete choice of clear or obscure double or triple-glazed units, all having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill.  Glass upgrades to enhanced security laminated glass, integral blinds, or acoustic glass units are all available with a quality-made Exlabesa KC51 window by Aluminium Doors and Windows Ltd.
