Replacement Skylight Diffusers

What are replacement skylight diffusers?

A replacement skylight diffuser is a component of a skylight that is designed to diffuse and distribute natural light evenly throughout a room. It is typically made of a translucent material, such as acrylic or polycarbonate, and is installed over the opening of the skylight to disperse the incoming sunlight. Sitting neatly inside the skylight frame, a diffuser helps to reduce glare and hot spots. Diffusers help create a more comfortable and balanced lighting environment. In case the diffuser gets damaged or worn out, a replacement diffuser panel or dome can be installed to restore the functionality and aesthetics of the skylight.

How to measure round replacement skylight diffusers

To measure a round skylight diffuser, you will need a measuring tape or ruler. Follow these steps:
1. Determine the diameter: Measure the distance across the widest part of the diffuser. This will give you the diameter of the diffuser. Make sure to measure from one edge to the opposite edge, passing through the center of the diffuser.
2. Note any additional features: If your skylight diffuser has any additional features, such as a lip or flange, is it ventilated or not and domed or flat. Make sure to note these variables as well.
In some cases your diffuser will be smashed in which case do the best you can or seek advice from a Skybrite professional.
By accurately measuring the diameter of your round skylight diffuser, you will be able to find the correct replacement size for your skylight.

How to measure a square and rectangle replacement skylight diffusers

To measure a square or rectangle skylight diffuser, you will need a measuring tape.
1. Measure the length: Measure the distance from one side of the diffuser to the opposite side. This measurement is called the edge to edge measurement. This will give you the length of the diffuser. Make sure to measure from the outer edges of the diffuser.
2. Measure the width: Measure the distance from the other two sides of the diffuser. This will give you the width of the diffuser. Again, measure from the outer edges.
3. Again note any additional features of your skylight diffuser that might differentiate it from a standard stocked item.
By accurately measuring the length and width of the square or rectangle skylight diffuser, you will go a long way to finding the correct replacement size.
Replacement skylight diffusers varying shapes and designs
Flat Skylight Diffusers:
Flat skylight diffusers, as the name suggests, have a flat surface and are typically used in skylights that have a flat or low-profile design. They are often made of materials like acrylic or polycarbonate and are designed to evenly distribute natural light throughout a room. Flat diffusers are known for their sleek and minimalist appearance, making them suitable for modern and contemporary styles. They provide a clean look while still allowing ample natural light to enter the space.
Domed Skylight Diffusers:
Domed skylight diffusers on the other hand have a curved or domed shape. The curved shape of the diffuser helps to capture and spread natural light more effectively, allowing for greater light diffusion and distribution. Domed diffusers are often made of materials like acrylic or polycarbonate and are designed to reduce glare and hot spots while providing a softer and more diffused light. They are popular in both residential and commercial settings and can add a unique architectural element to a space.
Ventilated Skylight Diffusers incorporate a ventilation functionality. It combines natural light diffusion with the ability to introduce fresh air into a space.
A ventilated diffuser typically consists of a diffuser panel with small openings or vents strategically placed. These vents allow for a passage of air to pass between the interior and exterior of the building. The diffuser panel itself is usually made of a translucent material to allow for the diffusion of natural light. Ventilated diffusers are often installed in kitchens and bathrooms.
The ventilation aspect of a ventilated diffuser design can be achieved in different ways. Some designs may incorporate adjustable vents that can be opened or closed to control the airflow. Others may have a separate ventilation system connected to the diffuser, allowing for more precise control over the air exchange.
It’s important to note that the specific design and features of a ventilated diffuser may vary substantially. Consulting with a Skybrite professional can help you determine the best replacement ventilated diffuser you need.
Both flat and domed skylight diffusers, ventilated on non vented diffusers, serve the purpose of diffusing and distributing natural light, but their different shapes cater to different skylight designs and architectural styles. The choice of diffusers depends on the specific requirements of the skylight model and usage. Call 1300 186 262 if you have any questions.
How to install replacement skylight diffusers
Installing a replacement skylight diffuser can vary depending on the specific skylight system and diffuser design. However, here are some general steps to guide you through the installation process:
1. Safety: Before starting any installation, ensure that you have taken necessary safety precautions, such as working on a stable surface.
2. Remove the old diffuser: If there is an existing diffuser in place, carefully remove it by unscrewing or unclipping it from the skylight ceiling insert, skylight ceiling surround or skylight frame.
3. Clean the skylight frame: Once the old diffuser is removed, clean the skylight frame to ensure a debris free surface for the new diffuser.
4. Position the replacement diffuser: Carefully position the replacement diffuser onto the ceiling insert, ensuring that it sits securely and evenly. This will vary depending on whether you have attached a domed twist and turn style, flat diffuser or ventilated diffuser model.
5. Secure the diffuser: Depending on the design of the diffuser and skylight system, use the appropriate screws, clips, or fasteners to secure the replacement diffuser in place. Many diffuser also simply drop into the skylight frame and sit on the internal lip provided.
Please note that these steps are general guidelines, and the specific installation process will vary depending on the skylight system and diffuser design. If you are unsure or uncomfortable with the installation process, it is recommended to seek professional advice from a Skybrite expert.

Acrylic and polycarbonate replacement skylight diffusers

The two main materials commonly used for skylight diffusers are:
1. Acrylic: Acrylic is a lightweight and durable material that is often used for skylight diffusers. It is known for its high transparency, allowing for excellent light transmission. Acrylic diffusers are resistant to UV radiation and can withstand exposure to sunlight without yellowing or becoming brittle over time. They are also relatively easy to shape and can be molded into various sizes and designs. Acrylic diffusers are popular for their versatility, and ability to provide a soft and diffused light.
2. Polycarbonate: Polycarbonate is another popular material used for skylight diffusers. It is a strong and impact-resistant thermoplastic that offers excellent durability and longevity. Polycarbonate diffusers are highly transparent, allowing for efficient light transmission. They are also UV-resistant and can withstand prolonged exposure to sunlight without discoloration or degradation.
Both acrylic and polycarbonate skylight diffusers have their own advantages and are widely used in various skylight applications. The choice between the two materials depends on factors such as budget and desired light transmission.

Manufacturing various skylight diffuser designs

Skylight diffusers are manufactured using various methods and techniques. The method of production is the major impacting factor on the cost of different diffuser models. Here are a few different ways skylight diffusers can be produced:

1. Injection Moulding: Injection moulding is a common manufacturing method for skylight diffusers. It involves injecting molten plastic material, such as acrylic or polycarbonate, into a mould cavity. The material is then cooled to form the desired diffuser shape. Injection moulding allows for precise and consistent production of diffusers with complex shapes and details.

2. Vacuum Forming: Vacuum forming is another popular method for manufacturing skylight diffusers. It involves heating a plastic sheet, typically acrylic, until it becomes pliable. The heated sheet is then stretched and pressed onto a mould using vacuum pressure to create the diffuser shape. Vacuum forming is a cost-effective method for producing diffusers with simple shapes.
3. Extrusion: Extrusion is a process commonly used for manufacturing skylight diffusers with linear or continuous shapes. In this method, plastic material is melted and forced through a die, which shapes the material into the desired cross-sectional profile. The extruded diffuser is then cooled and cut to the desired length. Extrusion allows for high-volume production of diffusers with consistent dimensions.
4. Thermoforming: Thermoforming is a process similar to vacuum forming but typically used for thicker or more rigid plastic materials. It involves heating the plastic sheet until it becomes pliable and then pressing it onto a mould using mechanical force. Thermoforming can be used to produce skylight diffusers with various shapes and sizes.
The choice of manufacturing technique depends on factors such as the desired diffuser design, material properties and costs vs production volume.
