Roundup of Best Practices for Installing Fibreglass Insulation

Installing Batts and Rolls

When installing batts and rolls, it is essential to ensure a snug fit within the framing cavities. Begin by carefully measuring the spaces between studs or joists, as the insulation must match these dimensions. If insulation is too wide or too narrow, adjustments can be made using a utility knife or by compressing it slightly. The edges should fit tightly against the framing but take care not to compress the insulation excessively, as this can reduce its effectiveness.

It is advisable to maintain a clean workspace to prevent contaminating the insulation. When unfurling the batts, avoid tearing any protective facing as it may provide additional moisture resistance. For optimal performance, install the insulation with the paper or foil facing towards the interior of the home. This facing acts as a vapour barrier, helping to minimise moisture intrusion. Take time to check for any air gaps once the insulation is in place, as even small openings can significantly impact energy efficiency.

StepbyStep Installation Process

Begin by ensuring the area is clear of debris and any obstructions. Wear appropriate protective gear, including gloves, glasses, and a mask to avoid irritation from fibreglass strands. Measure the spaces between wall studs, joists, or rafters accurately. Cut the fibreglass batts or rolls to fit using a sharp utility knife. Ensure that they fit snugly but without compression, as compressed insulation loses its effectiveness.

Once cut, gently place the batts or rolls into the cavity, ensuring they are oriented correctly. It is vital to maintain the manufacturer's recommended thickness to achieve optimal thermal performance. For horizontal installations, secure the insulation in place using insulation supports or wire supports, if necessary. Once completed, double-check for any gaps or unfilled areas that may need additional insulation or sealing to enhance the system’s overall effectiveness.

Handling Loose Fill Insulation

Loose fill insulation offers flexibility in covering irregularly shaped spaces and hard-to-reach areas. This type of insulation is typically made from materials such as cellulose, fibreglass, or mineral wool, making it suitable for attics, walls, and crawl spaces. When working with loose fill, ensuring proper density is crucial for maximising thermal performance. Overloading can lead to settling, reducing the overall effectiveness of insulation over time.

For optimal results, use a blowing machine designed specifically for loose fill insulation. This equipment allows for an even distribution and can adjust the flow rate to control the amount of material being applied. Prior to installation, it is essential to prepare the space by sealing any gaps and ensuring the area is clean. This preparation enhances the performance of the insulation and prevents any potential air leakage that could undermine the benefits of the product.
