Common Questions
Which material should I choose?
If you are trying to choose between the 18oz and 12oz vinyl materials, please choose based on your environment. For regular weather conditions, 12 oz. vinyl is a great material at a slightly less expensive price. If you are going to experience heavy weather conditions such as heavy snow, heavy rain, and lots of wind, then please choose the 18 oz. vinyl material.
What is the most common material?
The 18 ounce vinyl is used to make 90% of the covers ALCO offers. Even though both materials are equally strong and look the same, the majority of customers pick the thicker material.
Are they easy to clean?
Yes. Contrary to other polyester covers that resemble canvas, vinyl is a material that is extremely slick and is therefore simple to clean. Canvas will capture and hold mold and stains that are difficult to remove, as opposed to the sleek ALCO Vinyl custom furniture covers.
How strong are the covers?
18 oz vinyl is a very strong and long-lasting material, in fact, it is the same material that is used on the semi trailers to cover their cargo! As you can imagine, the abuse the material can endure on the highway is extreme, and if they didn't hold up, the truckers would not use them. That is why 18 oz vinyl is one of the strongest covers that you can purchase.
My cover will be used indoors. Which material is ideal?
The 600D material is the perfect material for indoors or even outdoors if its mostly in the shade and not in harsh conditions.
Common Questions
Round Skylight Covers – Custom-Made Sizes: Frequently Asked Questions
What are round skylight covers used for?
They protect round skylights by reducing heat loss in winter and blocking UV rays during summer, keeping indoor spaces comfortable and energy-efficient.
Which materials are available?
Available in 12oz vinyl (medium duty) for standard weather protection and 18oz vinyl (heavy duty) for more extreme outdoor conditions.
How do I measure my skylight for a round cover?
Measure the full diameter of your skylight (Side A) and the height you want the cover to extend (Side C). We add slack for a snug yet proper fit.
Can these covers be used indoors and outdoors?
Yes. They perform well in both environments. Use 12oz vinyl for light-duty or covered applications and 18oz vinyl for fully exposed outdoor skylights.
Are the covers waterproof and UV resistant?
Yes. The vinyl material is 100% waterproof, UV stabilized, and resistant to cracking, ensuring your skylight remains protected year-round.
Do round skylight covers help with energy efficiency?
Absolutely. They minimize heat loss in winter and reduce heat gain in summer, contributing to better insulation and lower utility costs.
How thick and durable are the materials?
The 12oz vinyl is medium-weight and flexible, while the 18oz vinyl is thicker and extremely tough—ideal for wind, snow, and sun exposure.
How do I install a round skylight cover?
Most covers secure easily using tie-downs, elastic cords, or Velcro straps. They can also be attached to aluminum angles or beams using clamps or grommets.
Can I remove and reinstall the cover seasonally?
Yes. The lightweight vinyl allows for quick seasonal installation or removal without professional help, making it easy to maintain your skylight year-round.
What tie-down or mounting options are available?
You can choose from grommets, webbing straps, Velcro, or beam clamps. Each option ensures a secure fit depending on your installation type.
Can the covers handle snow and heavy rain?
Yes. The 18oz vinyl option is engineered to resist heavy snow loads and driving rain, preventing leaks or water pooling over skylights.
Are they easy to clean and maintain?
Yes. Simply wipe with mild soap and water using a soft cloth. The slick surface repels dust and debris, making maintenance simple.
