• Fire Resistance: Glass wool insulation board is non-combustible and achieves the highest Euroclass A1 fire rating. This means it won’t contribute to the spread of fire, providing an additional layer of safety for your home.
• Moisture Resistance: While glass wool can absorb some moisture, it is treated to be water repellent. This helps to prevent the insulation from becoming saturated and losing its thermal performance.
• Sustainable and Environmentally Friendly: Glass wool insulation board is made from recycled glass, making it a sustainable and environmentally friendly choice. It is also recyclable at the end of its lifespan.
• Easy to Install: These are lightweight and easy to handle insulation Board, making them suitable for DIY installation. They can be easily cut to size and fitted between rafters or joists.
• Cost-Effective: Glass wool insulation board is a cost-effective insulation solution compared to other options, such as PIR boards.

Types of Glass Wool Insulation Board for Roofs

There are different types of glass wool insulation board designed for specific roof applications:

• Pitched Roof Insulation Boards: These boards are designed to be installed between and over rafters in pitched roofs. They are available in various thicknesses to achieve different R-values and meet building regulations.
• Flat Roof Insulation Boards: These boards are designed for use in flat roof applications. They offer high compressive strength to withstand the weight of the roof covering and are often used in warm roof constructions.
• Acoustic Roof Insulation Boards: These boards offer enhanced sound absorption properties, making them ideal for reducing noise pollution from rain, wind, or traffic.

Choosing the Right Glass Wool Insulation Board

When choosing Glass wool insulation panels for your roof, consider the following factors:

• R-value: The R-value measures the thermal resistance of the insulation. Higher R-values indicate better insulation performance. The recommended R-value for your roof will depend on building regulations and your desired level of thermal comfort.
• Thickness: The thickness of the insulation board will affect its R-value. Thicker boards generally provide better insulation.
• Board size: Choose board sizes that are easy to handle and fit within your roof space.
• Existing insulation: If you have existing insulation in your roof, you may need to consider its type and thickness when choosing new insulation boards.
• Budget: Glass wool insulation boards are available at various price points. Consider your budget when making your selection.
• Specific requirements: If you have specific requirements, such as fire resistance or soundproofing, choose insulation boards that meet those needs.

Installing Glass Wool Insulation Board in Your Roof

Installing Glass wool insulation panels in your roof is a relatively straightforward process, but it’s important to follow the correct steps to ensure optimal performance:

1. Prepare the Roof Space: Clear any obstructions and ensure the roof space is well-ventilated.
2. Measure and Calculate: Measure the area of your roof to determine how much insulation you need.
3. Choose and Purchase: Select the appropriate glass wool insulation boards based on the factors mentioned earlier and purchase them from a reputable supplier like Online Insulation.
4. Install the Boards: Start by installing the boards between the rafters or joists, ensuring a snug fit. Cut boards to size as needed using a sharp knife or saw.
5. Second Layer (if needed): If you require a higher R-value, install a second layer of insulation boards perpendicular to the first layer, ensuring all joints are staggered.
6. Seal Gaps: Use foil tape to seal any gaps or joints between the boards to prevent air leakage and maintain a continuous thermal barrier.

Safety Tips:

• Always wear appropriate safety gear, including gloves, a dust mask, and eye protection, when handling insulation materials.
• Ensure the roof space is well-ventilated to avoid inhaling dust and fibres.
• Take care when working at height and use appropriate safety equipment.
