Old Velux skylight sizes are an important consideration for homeowners, renovators, and contractors who are dealing with existing skylights or planning roof window replacements. Understanding the dimensions of older Velux models helps ensure proper fitting, energy efficiency, and aesthetic compatibility with your roof space. While modern Velux skylights have standardized sizes, older models often vary in width, height, and overall frame design. Knowing the exact dimensions of old Velux skylights can save time, prevent costly mistakes, and allow for a smoother installation or replacement process.
Introduction to Old Velux Skylights
Velux has been a leading manufacturer of roof windows and skylights for decades, and many older homes still feature their products. These skylights were designed to bring natural light into attics, lofts, and upper-level rooms, enhancing both the functionality and beauty of interior spaces. Over the years, Velux has introduced new models, but older skylights remain in use because of their durable construction and classic design. Homeowners often need to know the old Velux skylight sizes for repairs, replacements, or when adding blinds and accessories to existing units.
Common Old Velux Skylight Models
Old Velux skylights were produced in a range of models to suit different roof pitches and room types. Some of the common older models include the GGL, GPL, GGU, and GPU series, each designed with specific features such as manual or electric opening, double or triple glazing, and various frame materials. Understanding the differences between these models is crucial because each has slightly different measurements, which can affect replacement or retrofit options.
Standard Dimensions of Old Velux Skylights
Old Velux skylights were manufactured in several standard sizes, which typically include measurements based on width and height. These dimensions are often given in centimeters, reflecting both the size of the glass and the outer frame. While variations exist depending on the model and production year, the most common old Velux skylight sizes include
Typical Width and Height Measurements
- 55 cm x 78 cm
- 55 cm x 98 cm
- 66 cm x 98 cm
- 78 cm x 98 cm
- 114 cm x 118 cm
These measurements refer to the internal glass size or the overall frame dimensions, depending on the source. It is important to verify the exact measurement on your existing skylight to ensure proper fitting when ordering replacement units or accessories. Minor discrepancies in size can result in improper sealing or difficulty fitting blinds or shutters.
Why Knowing Old Velux Skylight Sizes Matters
Accurate knowledge of old Velux skylight sizes is critical for several reasons. First, it ensures that replacement skylights fit correctly without requiring major roof modifications. Second, understanding the size helps homeowners select compatible blinds, shades, or shutters, which often come in model-specific dimensions. Third, correct sizing maintains the energy efficiency and weatherproofing of the window, preventing leaks and drafts. Finally, knowing the dimensions simplifies the process of installing accessories like insect screens or blackout covers.
Measuring Old Velux Skylights
To measure an old Velux skylight accurately, you should follow a few key steps
- Measure the width of the frame from the inner edges.
- Measure the height from the top to the bottom of the frame.
- Check for any markings or labels on the skylight, as Velux often included model numbers that correspond to specific dimensions.
- Compare measurements to Velux size charts to identify the correct replacement or accessory size.
Measuring carefully ensures that you can match new components to the existing skylight, avoiding costly errors and ensuring proper installation.
Replacement Options for Old Velux Skylights
Replacing old Velux skylights can involve choosing between identical models or modern upgrades. Newer Velux skylights are often more energy-efficient, with better insulation and glazing technology. However, matching the exact size of an older model is crucial to avoid altering the roof structure. Velux provides retrofit solutions designed to fit older window openings, making it easier to modernize your skylight without major construction work.
Choosing the Right Replacement
When selecting a replacement skylight, consider the following
- Confirm the old Velux skylight size to ensure proper fit.
- Determine if you want a manual or electric opening mechanism.
- Choose glazing type based on insulation needs and natural light preferences.
- Check compatibility with existing blinds, shades, or external accessories.
- Consider aesthetic factors to match the roofline and interior décor.
Common Challenges with Old Velux Skylight Sizes
One challenge with old Velux skylight sizes is that older homes may have non-standard dimensions due to changes in building codes or custom installations. Additionally, over time, labels or model numbers may have faded, making it difficult to identify the original size. In such cases, careful measurement and consultation with Velux documentation or support services can help ensure the correct replacement size is selected. Another common issue is that older skylights may not meet current insulation standards, so upgrades often involve slightly adjusting the size or using retrofit frames to accommodate modern requirements.
Tips for Homeowners
- Always measure twice to confirm skylight dimensions before ordering replacements.
- Consider taking a photo of the existing skylight and any labels for reference.
- Check if Velux offers retrofit frames that match old skylight sizes for easy installation.
- Consult with a professional installer if roof structure or weatherproofing is a concern.
- Keep a record of old Velux skylight sizes for future maintenance or replacement projects.
Old Velux skylight sizes play a vital role in maintaining, replacing, or upgrading roof windows in older homes. Knowing the exact dimensions ensures proper fitting, compatibility with accessories, and long-term performance. From historical models to modern retrofit solutions, understanding these sizes allows homeowners and contractors to make informed decisions while preserving the functionality and aesthetic appeal of their skylights. Accurate measurements, awareness of common challenges, and careful planning are key to successfully working with old Velux skylights, ensuring that these classic windows continue to bring natural light and comfort to living spaces for years to come.
