Introduction
Installing a skylight can significantly enhance your living space by increasing natural light, improving energy efficiency, and adding to the overall value of your home. While professional installation is recommended, competent tradespeople or skilled DIY enthusiasts can follow this guide to complete the installation successfully.
Benefits of Installing a Skylight
Energy Savings: Reduce electricity usage by increasing natural lighting.
Improved Home Value: Enhance resale value with modern upgrades.
Spacious Feel: Make rooms feel larger and more open.
Increased Natural Light: Brighten up dark areas without additional wiring.
Important Considerations Before Installation
Ensure compliance with local building codes, particularly for load and wind resistance.
Confirm all measurements and materials before cutting or ordering products.
All roof lights are made to order; sizes cannot be altered after glass cutting or toughening.
Review and understand all instructions before beginning the installation process.
Step-by-Step Skylight Installation
1. Preparing the Opening
Upstand Opening: Allow for a 5mm tolerance on each side of the skylight.
Example: A 400mm x 400mm skylight requires a 410mm x 410mm opening.Top Glass Overhang: The top pane extends 100mm beyond the quoted size on all sides.
Example: A 400mm x 400mm skylight will have a top pane of 600mm x 600mm.Pitch Requirement: Minimum 5° pitch to prevent water pooling.
2. Building the Upstand
Use good quality timber that protrudes at least 150mm above the roof level.
Apply roof covering material to the upstand for weatherproofing.
Recommended support timber: 25mm x 50mm (2” x 1”) as shown in the installation diagram.
3. Sealing and Fitting the Skylight
Ensure all silicone application areas are clean and dry.
Place foam rope on top of the supporting timber to prevent pressure on the bottom glass.
Apply a high-quality weatherproof sealant to the upstand.
Position the skylight using suction cups and secure it in place.
Test water flow before final sealing to ensure no pooling occurs.
