Skylights are particularly beneficial in countries like Pakistan and India because we have abundant sunlight, which makes them a highly effective source of natural light. Additionally, in Pakistan we face major electricity issues where people are unable to light their homes during the day because of load-shedding etc. Incorporating skylights helps reduce the dependency on artificial lighting, which is not only energy-efficient but also cost-effective—especially in areas where electricity costs are high or power outages are frequent. The natural light that skylights provide also improves indoor air quality, creating a more inviting and healthier living space. Additionally, well-placed skylights can help in temperature regulation by allowing ventilation making homes more comfortable year-round in Pakistan’s varied climate. So yes, this way skylights can also act as ventilators!
There are some points we need to keep in mind when deciding on the right type of skylight.
First of all, we need to select the most optimal placement for it:
Optimal positioning is crucial for maximizing the benefits of skylights. Considering the roof structure and any existing impediments, such as beams or vents, is crucial for ensuring safe and effective installation.
Next, we need to examine the sun’s orientation concerning your residence. South-facing skylights get the maximum sunshine, potentially resulting in overheating, particularly in warmer regions. East-facing skylights are optimal for morning sunshine, whilst west-facing skylights offer warm, afternoon illumination. North-facing skylights provide steady yet soft daylight, rendering them optimal for sustaining moderate indoor temperatures.
Another factor is the room in which the skylight will be installed. Skylights enhance kitchens, baths, and hallways by providing essential natural light.
Next, we need to choose the appropriate shapes and varieties available for skylights.
Skylights are available in various shapes and designs, each tailored to certain architectural requirements. The primary categories encompass:
Fixed Skylights: These non-venting, sealed structures are designed to avoid leaks and are optimal for illuminating areas such as corridors or living rooms with abundant natural light.
Ventilated Skylights: These skylights can be operated manually or electronically, facilitating ventilation, making them suitable for humid environments such as kitchens and bathrooms.
This is where skylights can be both used ingeniously for natural lighting and ventilating the House so it is very important to understand for an energy efficient home.
A ventilated skylight, or operable skylight, is an ideal choice for homeowners seeking both natural illumination and airflow in one solution. These skylights can be operated manually or through electric or solar-powered systems, facilitating the ingress of fresh air and sunlight into the residence.
Various versions exist for this concept, such as physical Ventilated Skylights, which are operated using a hand crank or pole; they are more straightforward but necessitate physical effort.Electric ventilated skylights, operable via remote control or wall switch, provide enhanced convenience and are particularly suitable for installations in inaccessible areas.If your budget permits, consider solar-powered ventilated skylights with a tiny solar panel, as they are energy-efficient and environmentally sustainable. They frequently incorporate sensors that enable automated closure upon detecting rainfall, hence enhancing protection and ease.
Angled skylights, set at a modest angle or perpendicular to the sun’s beams, effectively diminish the intensity of light entering a space, so reducing glare.
Next if your budget allows further you can look into some sophisticated Glazing Technology
Contemporary skylights employ sophisticated glazing technology to reduce heat absorption and shield against ultraviolet radiation. Below are several prevalent glazing alternatives. These will help you manage heat gain and glare:
Low-E (Low Emissivity) Glass: This glass features a thin metallic coating that reflects heat while permitting light transmission. Low-E glass aids in regulating indoor temperatures, hence diminishing the necessity for air conditioning during the warmer months.
Double or triple-pane glass offers insulation, maintaining lower temperatures in summer and warmer conditions in winter. It additionally mitigates condensation and diminishes external noise, fostering a more comfortable living environment.
Tempered or Laminated Glass: These glass varieties provide resilience and safety, particularly in regions susceptible to severe weather conditions. Laminated glass effectively obstructs UV rays, safeguarding your furniture and interior surfaces from deterioration.
Leak Mitigation Strategies to prevent water leakage during rain:
Water infiltration is a prevalent issue associated with skylights, particularly in areas experiencing substantial precipitation or snowfall. Proper installation and sealing are crucial to prevent this problem. Here are several solutions that improve leak prevention:
Flashing Kits: Flashing refers to the material employed to seal the skylight and inhibit water infiltration. Numerous skylights are equipped with pre-fabricated flashing kits, intended to ensure a seamless, waterproof installation. It is essential to choose a flashing kit that corresponds with the roofing material, be it shingles, tiles, or metal.
Self-Sealing Skylights: Certain skylights are equipped with integrated sealing mechanisms that provide enhanced leak prevention. Self-sealing designs consist of many layers of waterproofing and insulation that serve as a robust barrier against water infiltration.
Roof Pitch Consideration: A skylight should be set at an angle that aligns with the roof’s slope to provide adequate drainage. Flat or low-slope roofs may necessitate additional preventive measures to avert water accumulation and leaks.
Overall, how can we effectively prevent leakages:
Proper installation and maintenance are crucial to prevent skylight leaks. Begin by verifying that the skylight is expertly fitted with the appropriate slope, even on flat roofs, to facilitate water drainage. Your architect can assist with this. High-quality flashing, including step or pan flashing, must be used to establish a watertight seal, while the application of waterproof membranes surrounding the flashing provides further protection. Selecting skylights equipped with integrated leak-prevention mechanisms or self-cleaning glass can mitigate water accumulation and avert leaks, particularly in regions prone to high rainfall.
Overall, consistent maintenance is essential—removing debris, dust, examining seals, and monitoring for excessive condensation can avert problems before they arise. Moreover, maintaining unobstructed gutters and rectifying any roof damage surrounding the skylight guarantees proper water drainage and prevents pooling. These procedures provide leak-proof skylights, rendering them a dependable source of natural illumination and ventilation in your residence.
