What Is Knauf Loft Insulation Roll?
Knauf Loft Roll 44 is a high-performance, non-combustible glass mineral wool insulation quilt, specifically engineered for thermal insulation in pitched roofs (at ceiling level) and floor applications.
These 1140mm wide, short-length rolls are precision-manufactured with partial perforations, enabling easy segmentation into either two 570mm wide rolls or three 380mm wide rolls to suit varying installation needs.
When installed in dual layers between timber joists with spacings of 400mm or 600mm, Loft Roll 44 significantly enhances thermal efficiency, minimising heat loss and optimising energy performance in residential and commercial spaces.
Understanding Knauf’s ECOSE Technology
Knauf’s ECOSE Technology is an innovative, sustainable binder system used in the manufacturing of mineral wool insulation. Unlike traditional binders, which often contain formaldehyde and other petrochemicals, ECOSE Technology replaces these with bio-based, renewable materials. This ensures that Knauf's products are not only environmentally friendly but also contribute to improved indoor air quality.
The use of ECOSE enhances the performance of Knauf Insulation by making it softer to the touch, reducing dust, and eliminating the unpleasant odours commonly associated with conventional loft insulation.
Furthermore, products incorporating this technology have a lower embodied carbon footprint, supporting sustainable building practices and meeting rigorous environmental standards.
Benefits
- Excellent thermal performance.
- Odourless, rot-proof and non-hygroscopic.
- Does not sustain vermin nor encourage the growth of fungi, mould or bacteria.
- Contains no ozone-depleting substances or greenhouse gases.
- Euroclass A1 reaction to fire classification.
- Compression-packed and lightweight for easy handling and moving around site.
Installation
- To begin, clear the loft space of any debris or obstructions. Starting at one end, unroll the insulation across the joists, cutting it to the desired length with a sharp utility knife.
- Be careful not to compress the insulation, as this can reduce its effectiveness. If needed, additional layers can be added perpendicular to the first to achieve the desired thermal performance.
- Ensure you insulate around pipes, cables, and electrical fixtures to maintain safety.
- Once installation is complete, inspect for any gaps or areas that may need attention and confirm that the insulation is evenly distributed throughout the loft.
It is recommended to wear appropriate protective clothing, such as gloves and a dust mask, during the installation process.
Safety Considerations
- During the installation process, it is crucial to handle the insulation with care and follow the recommended safety guidelines.
- Always wear appropriate protective equipment, such as gloves and a dust mask, to minimise exposure to any potential irritants.
- Take necessary precautions when working around electrical fixtures, ensuring that insulation is properly installed and does not come into direct contact with any wiring or fittings.
- Additionally, it is essential to maintain proper ventilation in the loft space to allow for adequate air circulation.
Frequently Asked Knauf Loft Roll Questions
How Many Knauf Loft Insulation Rolls Do I Need for My Loft?
The number of Knauf Loft Insulation Rolls you’ll need depends on the size and layout of your loft, as each space has unique dimensions and insulation requirements.
To calculate the amount of insulation required, measure the width and length of the areas you want to insulate to determine the total square meters (m²). Then, divide this total by the size of the roll to find how many rolls you’ll need.
We recommend adding an extra 5-10% to account for wastage, ensuring you have enough material for the job.
Can Knauf Loft Insulation Rolls Still Be Installed If I Have Down Lights?
Yes, Knauf Loft Insulation Rolls can still be installed even if you have downlights. However, it’s important to take special precautions around the fixtures. Installers will usually cut the insulation around the downlights and ensure they are covered with a protective cap. This prevents insulation from coming into direct contact with the lights, which could pose a fire risk.
Make sure the installation complies with safety regulations and that clearance is maintained around the downlights.
What Is The Recommended Knauf Loft Insulation Roll Depth?
Between 270-300mm.
