Discover skylights: roof windows for houses

Posted by Alex Roof

Are you looking to brighten up your home with more natural light? One of the best ways to do so is by installing skylights, also known as roof windows. Skylights are a popular feature in modern homes, as they not only enhance the aesthetic appeal of the interior but also provide numerous health and energy benefits. By allowing natural light to flow into your home, skylights can improve your mood, reduce energy consumption, and increase the value of your property. However, with so many types, materials, and installation options available, choosing the right skylight for your house can be a daunting task. In this article, we will guide you through the process of discovering skylights and help you make an informed decision that suits your needs, preferences, and budget.

Types of roof skylights

Skylights come in various shapes, sizes, and styles, each with its own unique features and benefits. The most common types of skylights are:

  1. Fixed Skylights
    Fixed skylights are the most basic type of skylight and are typically used for providing natural light and ventilation to attics, hallways, and other areas that do not require regular access. Fixed skylights are stationary and cannot be opened or closed.
  2. Ventilating Skylights
    Ventilating skylights, also known as operable skylights, are designed to open and close, allowing fresh air to circulate through the room. Ventilating skylights can be operated manually, with a hand crank or pole, or automatically, with a remote control or a built-in sensor that detects temperature, humidity, or carbon dioxide levels.
  3. Tubular Skylights
    Tubular skylights, also known as sun tunnels or light tubes, are a smaller and more affordable option for bringing natural light into your home. Tubular skylights are typically installed in rooms with limited roof space, such as closets, bathrooms, or hallways, and consist of a small dome on the roof and a reflective tube that channels sunlight into the room.
  4. Custom Skylights
    Custom skylights are made to order and can be customized to fit any shape or size of the roof. Custom skylights are typically more expensive than standard skylights, but they offer more flexibility in terms of design and functionality. Custom skylights can be made of various materials, including glass, acrylic, or polycarbonate, and can be fixed or ventilating, depending on your needs.

When choosing a type of skylight, consider the purpose of the room, the size and orientation of the roof, and your budget and energy efficiency goals. Fixed skylights are a good choice for rooms with high ceilings or limited space, while ventilating skylights are ideal for rooms that require ventilation, such as kitchens or bathrooms. Tubular skylights are a great option for small rooms or areas that cannot accommodate a larger skylight. Custom skylights are suitable for unique or complex roof structures and can be tailored to your specific requirements.

Materials for skylights

Skylights can be made of various materials, each with its own advantages and disadvantages. The most common materials for skylights are:

  1. Glass Skylights
    Glass skylights are the most traditional and popular type of skylight. Glass skylights offer excellent clarity, durability, and resistance to scratches and discoloration. Glass skylights are available in various types, such as tempered glass, laminated glass, or insulated glass, and can be single or double pane. Insulated glass skylights are the most energy-efficient option, as they can reduce heat loss and gain, and noise transmission.
  2. Acrylic Skylights
    Acrylic skylights, also known as plastic skylights, are a more affordable and lightweight alternative to glass skylights. Acrylic skylights are made of a type of plastic called polymethyl methacrylate (PMMA), which is highly resistant to impact, UV radiation, and weathering. Acrylic skylights offer good insulation and soundproofing properties and are available in various colors and designs.
  3. Polycarbonate Skylights
    Polycarbonate skylights are similar to acrylic skylights but are even more durable and impact-resistant. Polycarbonate skylights are made of a type of plastic called polycarbonate, which is virtually unbreakable and can withstand hail, wind, and extreme temperatures. Polycarbonate skylights are also lightweight and easy to install, but they may be less clear and prone to scratching.

When choosing a material for your skylight, consider the location, climate, and maintenance requirements. Glass skylights are a good choice for areas with heavy rain or snow, as they are less prone to leaking or condensation. Acrylic and polycarbonate skylights are suitable for areas with high winds or hail, as they are more resistant to damage. Insulated glass skylights are a great option for areas with extreme temperatures or noise pollution, as they can improve the energy efficiency and soundproofing of your home.

Factors to consider when choosing skylights

Choosing the right skylight for your home can enhance your living space and bring natural light and ventilation into your rooms. Here are some factors to consider when selecting a skylight:

  • Purpose. Consider the purpose of the room and how you want to use the skylight. Do you want to bring in more light, add ventilation, or create a focal point? Fixed skylights are ideal for rooms with high ceilings or limited space, while ventilating skylights are suitable for areas that require fresh air, such as kitchens or bathrooms.
  • Size. Determine the size of the skylight based on the size and orientation of your roof and the amount of light you want to bring in. Skylights that are too small may not provide enough light or ventilation, while skylights that are too large may cause glare or heat loss.
  • Location. Consider the location of the skylight in relation to the sun and the surrounding environment. North-facing skylights receive less direct sunlight and are suitable for bringing in ambient light, while south-facing skylights receive more direct sunlight and can provide passive solar heating. East-facing skylights are ideal for morning light, while west-facing skylights are best for afternoon light.
  • Energy Efficiency. Look for skylights that are energy-efficient and can help you save on heating and cooling costs. Insulated glass, low-E coatings, and gas fills can improve the energy efficiency of your skylight and reduce heat loss and gain.
  • Material. Choose a material for your skylight based on the climate, maintenance requirements, and aesthetic preferences. Glass skylights offer excellent clarity and durability but may be more prone to breaking in extreme weather. Acrylic and polycarbonate skylights are more lightweight and impact-resistant but may require more frequent cleaning.
  • Installation. Consider the installation process and the expertise required. Skylights that require cutting into the roof structure may require professional installation, while tubular skylights can be installed by a DIY homeowner.

By considering these factors, you can choose a skylight that meets your needs and enhances the beauty and functionality of your home.

Installation of skylights

Installing a skylight requires careful planning, preparation, and execution to ensure that it functions properly and does not cause any damage to your roof or interior. Here are some steps to follow when installing a skylight:

  1. Choose the location for the skylight based on the factors discussed in the previous chapter, such as purpose, size, orientation, and energy efficiency. Mark the outline of the skylight on the roof, using a chalk line or a template.
  2. Cut the hole for the skylight using a reciprocating saw or a circular saw. Be sure to follow the manufacturer’s instructions and safety guidelines, and avoid cutting any roof rafters or electrical wires. Remove the debris and clean the area around the hole.
  3. Install the flashing around the hole to prevent water and air infiltration. Use a self-adhesive membrane, such as a peel-and-stick product, or a metal flashing, such as aluminum or copper. Follow the flashing instructions carefully and make sure it is secure and watertight.
  4. Install the skylight frame into the opening, using screws or brackets. Make sure the frame is level and flush with the roof, and use sealant or caulk to seal the edges.
  5. Install the glass panel into the frame, using clips or adhesive. Follow the glass installation instructions and safety guidelines, and make sure the glass is secure and level.
  6. Test the skylight for leaks, drafts, and proper operation. Check the flashing, frame, and glass for any gaps or cracks, and make adjustments as necessary.
  7. Finish the interior around the skylight, using drywall, trim, or paint. Install blinds or shades to control the amount of light and heat, and add ventilation accessories, such as a screen or a fan, if desired.

Installing a skylight can be a challenging task, and it is recommended to hire a professional roof contractor or a licensed roofer to ensure that the skylight is installed safely and correctly. A well-installed skylight can provide many years of natural light, ventilation, and energy savings for your home.

Decorative and functional options for skylights

Skylights are not only practical but can also be customized to suit your aesthetic and functional preferences. Here are some options to consider when choosing skylights:

    Skylights can be fitted with blinds or shades to control the amount of light and heat that enters the room. Roller shades, cellular shades, pleated shades, and Venetian blinds are all available options. Motorized shades can be operated by remote control or a wall switch and can be programmed to open and close automatically based on the time of day or the amount of sunlight.
  • Built-in Lighting
    Skylights can also be equipped with built-in lighting to provide additional illumination to a room. This option is particularly useful if you want to have natural light during the day and artificial light during the evening or nighttime.
  • Rain Sensors and Automatic Closing Features
    Some skylights come with rain sensors that automatically close the window when it detects rain. This feature is especially helpful when you are away from home and want to avoid water damage. Additionally, automatic closing features can prevent heat loss and help to regulate the temperature in the room.
  • Impact-Resistant Glass and Security Measures
    If you live in an area prone to severe weather conditions, you may want to consider skylights with impact-resistant glass. This glass is designed to withstand high winds, hail, and other debris. Additionally, security measures such as reinforced frames and locking mechanisms can provide additional protection against intruders.
  • Glazing
    Skylights come in various glazing options, including clear, tinted, frosted, and decorative glass. Clear glass provides maximum clarity and light transmission, while tinted glass reduces glare and UV rays. Frosted glass adds privacy and diffuses light, while decorative glass adds a unique touch of style and elegance.

By considering these options, you can choose a skylight that not only brings natural light and ventilation into your home but also enhances your style and comfort. Consult with a skylight professional to learn more about the available options and find the best solution for your needs.
