Question:
is that the smallest window available? I've measured my 30 year old windows and they're 48.3=62.3
Answer:
It will depend how you have measured your window, Velux windows are sized from the external frame size.
They do have one smaller size which is 47 x 98
Question:
My windows are GGL-1. Will this be an exact replacement? What if I only need the sash and not the frame?
Answer:
Yes, a VELUX GGL CK01 2070, measuring 550 × 700 mm, is generally the modern replacement size for an old GGL-1 window. The old size code "1" corresponds to the current CK01 size family (550 × 700 mm). Size-wise, the frame opening dimensions are the same size class, so the CK01 is the correct modern replacement for a GGL-1. However, it's important to note that if your GGL-1 window dates from before 1991, the window design, hinges, glazing, ventilation flap, and flashing interfaces have changed significantly over the years. A complete new CK01 window is intended to replace the whole unit, not just swap into the old frame. If you only need the sash and not the full frame, the situation can be a bit more complex. For older windows like the GGL-1, VELUX has discontinued many spare parts and sash assemblies due to their age. Replacement sashes are generally only readily available for newer generations. If your existing frame is sound and you only have issues such as failed glazing, rotten sash timber, or damaged handles or hinges, your options usually include obtaining a specialist replacement sash (if still available), replacing only the glass through a glazing specialist, or replacing the complete window with a new CK01 unit. The best way to confirm your specific situation is to open the window and look at the data plate on the top edge of the sash. If you can provide the full code (for example, GGL-1, GGL 101, GGL C01, plus any numbers after it), we can inform you about the exact age range, whether a sash-only replacement is likely available, and whether the CK01 2070 will fit using the existing flashing or if flashing replacement is recommended.
Question:
What is the u value
Answer:
The U-value refers to the thermal transmittance or insulation level of the window. For the VELUX GGL CK01 Centre Pivot Roof Window, it varies depending on the type of glazing you choose. The (070) Double Glazing has a U-value of 1.3 W/m2k, indicating a good level of insulation. The (066) Triple Glazing offers enhanced energy efficiency with a U-value of 1.0 W/m2k, providing even better insulation. The lower the U-value, the better the material is at insulating.
