A-rated performance signifies high energy efficiency, meaning the window is very effective at preventing heat loss. This helps to reduce your heating costs and makes your home more comfortable year-round.
The handing is determined by looking at the window from the outside. If the hinges are on the left and the handle is on the right, it's a right-hand opening window. If the hinges are on the right and the handle is on the left, it's a left-hand opening window.
While technically possible, professional installation is highly recommended to ensure proper sealing, structural integrity, energy efficiency, and compliance with building standards. Incorrect installation can lead to performance issues and void warranties.
The U Value measures how well a window prevents heat transfer. A lower U Value indicates better insulation. This window has a U Value of 1.4 W/m2K, which is considered very good for energy efficiency.
Regular cleaning, perhaps once or twice a year, is recommended to maintain appearance and performance. Focus on cleaning the glass and frames, and check the hardware and seals periodically.
Trickle ventilation provides a continuous, low level of background ventilation. This helps to manage humidity, reduce condensation, and maintain indoor air quality without significant heat loss or security compromise.
Yes, the black finish on the PVC frame is designed to be durable and weather-resistant, requiring minimal maintenance.
Check for any obstructions in the frame or mechanism. Ensure the espag locking handles are fully disengaged. Lubricate the locking points and hinges with a silicone-based spray.
Minor condensation can be normal, especially in humid conditions or temperature changes. Ensure trickle vents are open and clear. If persistent and significant, check the seal of the glazing unit or consult a professional.
Verify that the espag locking mechanisms are fully engaged. Check the condition of the weather seals around the frame and glass. If seals are damaged or worn, they may need replacement by a professional.
This indicates a failure in the glazing unit seal, allowing moisture to enter. The sealed unit will need to be replaced by a professional installer.
Setup: Installation of the Crystal Double Glazed Window requires professional expertise to ensure a secure, weather-tight fit and compliance with building regulations. It is crucial to ensure the opening is precisely measured to match the window dimensions (1770 x 1040mm). Handing (left or right opening) must be determined from the exterior view before fitting.
Compatibility: This window is designed for standard residential wall openings. Compatibility with existing frames depends on the exact dimensions and type of opening. The black colour offers a modern aesthetic that pairs well with contemporary building materials.
