4 Crucial Aspects Worth Knowing About Installing Skylights In High-Bushfire Regions

It’s no secret that many parts of Australia experience devastating bushfires every year. This means that locals building homes or commercial spaces in these areas should take significant precautions to ensure that their structures remain as safe as possible.

An important factor here involves the planning process when opting for the skylight installation Melbourne installers are offering. How will your skylights stand up to bushfires? Continue reading as we explore a few key points to consider when selecting skylights in fire-prone areas.

Understanding The Risks Posed By Skylights

Many homeowners are hesitant when it comes to installing skylights, especially if they live in bushfire-prone regions. There are a few significant reasons for this.

  • Inferior quality skylights: Cheap skylights are often made of inferior materials. For instance, plastic easily melts, cracks, or can even shatter from the heat, allowing flying embers to enter the structure.
  • Glazing failure: Glass skylights have also been known to shatter in extreme temperatures. This makes for easy entry for embers and improves the risk of injury from flying glass.
  • Fall hazard to firefighters: If a skylight breaks or melts away, the open gap could pose a risk of falling for firefighters who don’t know that skylights are there.

It’s Not All Doom & Gloom

When you first hear about the potential risks associated with skylights in a fire-prone area, you may be wondering if installation is worth it. The good news is that there are a few factors that will help you understand how having the right installation done will reduce the overall risk.

1. Always Opt For Professional Installation

You may be an avid DIYer who enjoys the challenge of installing a new project around your home. However, when it comes to skylights, it’s always recommended to use a professional and reputable skylight installer to have your skylights installed.

Doing this will ensure that quality products are installed, specially chosen by your installer for your area’s risk factor. In addition to this, an expert will have the skills and tools to install your skylight correctly.

2. Understand The Local Bushfire Attack Level (BAL)

One of the top tasks performed by an installer is to assess the average BAL reading for your area. Typically, the Bushfire Attack Level (BAL) is the Australian standard that assesses a building’s general fire risk. These risks often include the following:

  • Windborne flying embers
  • Exposure to surrounding radiant heat
  • Potential flame contact when surrounding fires move nearer to your home

The BAL measurement is designed to consider how these factors will

Affect surrounding buildings. This means knowing what damage fire will cause to your building materials. Factors worth considering here are listed as:

  • The Registered Fire Danger Index
  • Land slope and presence of hills near your property
  • Vegetation species around your property
  • How close to a fire-prone region your property is

3. Choose The Right Products

When it comes to skylights, they may look very similar, but it’s essential to know that aspects such as materials, type, and size all vary. Professional installers understand the risks and dangers associated with bushfires and flying embers. This means that they will often recommend one of two options to reduce the risk:

VELUX Skylights

VELUX is a leading brand in the skylight industry, and with good reason. These high-performance skylights have been rigorously tested and approved for buildings in bushfire-prone areas up to BAL40. Therefore, VELUX skylights can withstand a heat flux of 40kW/m.

Solatube Skylights

Solatube, another top option for custom skylights, can withstand readings from BAL-Low to BAL-29, which means they can withstand a heat flux of 29Kw/m. The gaps around Solatube skylights will be sealed at the roof to ensure there aren’t spaces greater than 3mm.

4. Knowing How BAL Is Measured

The Bushfire Attack Level is measured from minor to more severe readings. While not all houses may be in the immediate path of a bushfire, there’s always the high risk of flying embers. These can land on the roof, fly in through windows or even damage skylights.

The BAL measurement is determined by different readings which vary starting at low and go up to the more extreme BAL-FZ. These indexes are listed as:

BAL LOW: Minimal Risk Of Windborne Ember.

  • BAL 12.5: Slight risk of ember exposure with a minor heat flux of 12kW/m.
  • BAL 19: Higher levels of windborne ember exposure and potential debris ignition. The heat flux here averages 19kW/m.
  • BAL 29: Advanced risk of flying ember exposure and ignition. The heat flux here will have risen to 29kW/m.
  • BAL 40: Extreme risk of windborne embers with a high heat flux. This considerably increases the chances of flames reaching your property. A more severe heat flux of 40kW/m
  • BAL FZ: Also known as Extreme Level 5, this is the most severe rating and suggests properties will be in the immediate path of flames and embers. The heat flux will be higher than 40kW/m.

Final Thoughts

The key to having safe and functional skylights is to opt for professional installation and quality products. Speak to your local skylight expert for the perfect skylight solution, no matter where you live!
