Replacement Skylight Domes

Why do we need replacement skylight domes

There are several reasons why you may need replacement skylight domes for your skylight:
1. Damage: Skylight domes can get damaged due to various reasons such as hailstorms, falling debris, or extreme weather conditions. If your skylight dome is cracked, broken, or has any other form of damage, it is important to replace it to maintain the integrity of your skylight and prevent any leaks or further damage.
2. Aging: Over time, skylight domes can become worn out and lose their effectiveness. They may become discolored, brittle, or develop cracks due to exposure to sunlight and other environmental factors. Replacing an old skylight cover with a new one can improve the appearance and functionality of your skylight.
3. Energy Efficiency: Older skylight domes may not have the same level of insulation and energy efficiency as newer models. By replacing your old skylight dome with a new one that is designed to be energy-efficient, you can reduce heat loss in the winter and heat gain in the summer, leading to lower energy bills and a more comfortable living space.
4. Upgrading to a Better Design: If you have an older skylight dome that does not meet your aesthetic preferences or functional needs, replacing it with a new one can allow you to upgrade to a better design. There are various options available in terms of shape, size, and material, allowing you to choose a skylight dome that complements your home’s architecture and provides the desired amount of natural light.
In summary, replacing a skylight dome is necessary to address any damage, improve energy efficiency, and upgrade to a better design. It is important to choose a genuine high-quality replacement dome that is compatible with your existing skylight to ensure proper installation and long-term performance.

How to measure round replacement skylight domes

To measure a round replacement skylight dome, follow these steps:
1. Determine the diameter: Measure the width of the existing skylight dome from one side to the other, passing through the center. This will give you the diameter of the skylight dome from flange to flange.
2. Measure the flange size: The flange is the lip or edge of the skylight dome that rests on the roof. Measure the width of the flange from one side to the other. This measurement is important to ensure that the replacement dome will fit properly on your skylight flashing.
3. Measure the height: Measure the height of the existing skylight dome from the base to the top. This measurement will help you choose a replacement dome with the appropriate height.
4. Note any additional features: If your skylight dome has any additional features such as a ventilation opening or a built-in shade, make sure to note these measurements as well.
5. Check for any obstructions: Before purchasing replacement skylight domes, check for any obstructions such as roof vents or nearby structures that may affect the size or shape of the dome. Ensure that the replacement dome will fit properly without any interference.
Once you have these measurements, you can search for a replacement skylight dome that matches the dimensions and features of your existing skylight. If you have any doubts we do recommend consulting with a professional at Skybrite to ensure that you choose the correct replacement dome for your specific skylight model.

How to install replacement skylight domes
Installing a replacement skylight dome involves removing the old dome and installing the new one. Here is a general guide on how to install a replacement skylight dome:
1. Safety first: Before starting the installation, ensure that you have the necessary safety equipment, such as gloves and safety glasses. Use a stable ladder or scaffolding to access the skylight.
2. Remove the old dome: Carefully remove the screws or fasteners that hold the old skylight dome in place. Take note of the placement and order of the screws for reinstallation.
3. Clean the area: Clean the area around the skylight opening, removing any debris or old sealant. Ensure that the surface is clean and dry before proceeding.
4. Check the condition of the flashing: Inspect the skylight flashing for any damage or deterioration. If necessary, repair or replace any damaged parts before installing the new dome.
5. Position the new dome: Place the replacement skylight dome over the flashing, ensuring that it is centered and aligned properly. Secure the dome to the flashing using the fixings provided.
6. Install the screws or fasteners: Insert the screws or fasteners through the holes in the skylight dome and into the frame. Tighten them securely but avoid over-tightening, as it may cause damage to the dome or flashing or rubber grommets if they are being used.
It is important to note that the installation process may vary depending on the specific skylight dome and flashing model.

Different skylight dome materials

Skylight domes are typically made of either acrylic or polycarbonate materials. Acrylic is a transparent thermoplastic that is lightweight and offers good clarity. It is resistant to UV radiation and has excellent weatherability. Polycarbonate, on the other hand, is a durable and impact-resistant material that is also transparent. It is known for its high strength and ability to withstand extreme weather conditions. Both materials are commonly used in skylight domes due to their durability, light transmission properties, and resistance to yellowing or discoloration over time.

Skybrite uses high impact acrylic in all replacement skylight domes

High impact acrylic, also known as impact-modified acrylic, is a type of acrylic that has been specially formulated to have enhanced impact resistance. It is made by adding impact modifiers to the acrylic resin during the manufacturing process. The addition of impact modifiers improves the toughness and durability of the acrylic, making it less prone to cracking or shattering upon impact.
Compared to standard acrylic, high impact acrylic retains many of the desirable properties of acrylic, such as excellent optical clarity, weather resistance, and UV stability. It is also lightweight and can be easily fabricated and formed into various shapes and sizes. All Skybrite Skylight domes meet Australian Standards.
