Loft roll insulation is a lightweight, resilient, and fire-resistant solution. It is made of mineral wool or fibreglass and achieves an A1 Euroclass rating. It is also non-combustible. This means that it is safe to use in a home with young children or pets. If you are considering installing insulation in your loft, here are a few things to consider before you buy.
Insulation rolls are made of mineral wool or fibreglass
Mineral wool, also known as rock wool, is an effective form of insulation. It is a naturally fire-resistant material that is made from basalt or volcanic rock. Its name stems from its discovery during volcanic eruptions, where strong winds regularly blew molten lava into fine threads, similar to that of wool. These natural fibres are usually recycled and are used to create insulation rolls and batts.
There are two main types of mineral wool insulation. One is blanket-type insulation, while the other is loose fill. Mineral wool is low in density, so high-quality insulation rolls must be quite thick. They are usually applied in layers, with a steel sheet on top. The air gap between the two layers increases thermal inertia and acts as a radiation shield.
Mineral wool has a slightly better R-value per inch than fiberglass, and is more environmentally friendly. It is also more resistant to moisture than glass wool, making it easier to cut, move, and fit into tight spaces. In addition, it is fire-resistant and does not encourage mold or fungi growth.
They are lightweight, resilient and durable
Loft roll is a type of insulation that is designed for use in loft spaces. It is a highly durable and insulating material that is lightweight and resistant to abrasion and damage. It is made of fibreglass and is environmentally friendly. The fibreglass is non-hygroscopic and therefore does not support the growth of fungi or bacteria. The material is highly resilient and does not absorb moisture, making it an excellent choice for loft insulation.
They achieve an A1 rating on the Euroclass scale
Loft roll is a highly effective insulation product that is available for lofts. It is a lightweight, non-combustible and thermally efficient solution that is made from recycled glass fibres and mineral wool. It is packed tightly in compressed rolls and achieves an A1 rating on the Euroclass scale for fire resistance. It also has a low thermal conductivity (0.044 W/mK), making it an excellent insulator.
The Euroclass system categorises construction products to provide harmonised standards. Each product is classified into seven categories based on their reaction to fire. A1 is the highest level, and is awarded to insulation materials that are resistant to fire, smoke, and flaming droplets.
They are non-combustible
Loft rolls are an excellent option for homes that need to insulate their lofts, but don’t want to risk combustible insulation. Knauf Insulation offers a range of rolls that are suitable for residential applications. These roll insulations are non-combustible and are made from glass mineral wool. The rolls come in various sizes and can be cut to the size required.
Loft rolls can be installed yourself by using a high-quality adhesive. You can purchase rolls in different densities, including acoustic and fire-resistant. They can also be used to insulate suspended ceilings. Another option is ROCKWOOL HARDROCK Multi-Fix, which is a durable, renewable volcanic stone that is compatible with many flat roofing systems.
Loft rolls are also non-combustible. Unlike conventional insulation, these rolls are made of mineral wool or fibreglass. They are light-weight, non-combustible, and environmentally friendly. They are packed in a tightly-sealed polythene package to prevent damage and fire risk. They should be stored indoors under a waterproof covering, so that they are not exposed to rain, snow, or other elements.
Fire-resistant solutions inhibit the spread of fire and ensure the structural integrity of buildings. They provide peace of mind for specifiers and occupants, while preventing fire damage and loss of life. With the constant drive for improved energy efficiency, a significant number of combustible materials are being introduced into the built environment. Often these materials are not easily encapsulated on-site, which can limit their capabilities over time.
They are easy to install
Knauf Loft Insulation is an easy-to-install roll made from silicone-impregnated glass mineral wool. It’s the perfect solution for cold lofts and pitched roofs. The roll is lightweight and can be easily removed if necessary. It comes in a variety of sizes and can be used for both domestic and commercial applications.
To install loft roll, you’ll need a set of sturdy scissors, insulation cutter, and protective clothing. Make sure to choose rolls that are thicker than 270mm to maximize energy savings and keep energy bills low. Loft insulation rolls made of glass mineral wool are available in various thicknesses and help to reduce climate change and heat loss. They are also flexible and lightweight, making them easy to install.
Unlike insulative materials, loft roll insulation is easy to install. Typically, mineral fibre matting is available in 400mm (16in) rolls. The thickness can range from 100mm (4in) to 200mm (8in). In the UK, you should aim to use a total thickness of 200mm (8in). You can achieve this by using a thin layer of insulation over a thick layer of insulation.
They are odourless and non-hygroscopic
The Earthwool Loft Roll is a high-quality insulating material that prevents odours and prevents the growth of fungi, mould and vermin. It is a non-hygroscopic, odorless and rot proof material that is suitable for pitched roofs. The loft roll should not be left exposed to extreme weather conditions and should be stored indoors.
Knauf Loft Roll 40 offers superior thermal performance and can be laid at 400mm or 600mm centres. It is also available unsplit as a full width roll. The Knauf Loft Roll is odourless, rot proof and non-hygroscopic and does not sustain vermin and fungi. It is also zero Ozone Depletion Potential (ODP). It is available in 2 570mm wide rolls and three 380mm wide rolls.
They are not suitable for lofts with difficult access
Loft rolls are not suitable for lofts with restricted access because they compress the insulation and reduce its effectiveness. For such lofts, specialist products are used to raise the floor level above the insulation, which then makes the floorboards more accessible. Loft rolls are not suitable for lofts with limited access because they cannot be removed easily. Rigid insulation boards are also available, which are more expensive than loft rolls but offer the same heat-retaining qualities. Insulation boards are approximately half the thickness of loft rolls. They can also be fitted around light fittings as they are more rigid than rolls.
Loft insulation rolls are not suitable for lofts with difficult or impossible access because of their size. The width of loft insulation rolls tends to be about 1140mm. Most insulation material rolls are pre-cut with perforations, so they can be easily cut with a panel saw. You can buy crawling boards from most hardware stores.
If the loft is difficult to access, a more durable product is available for loft insulation. You can also use loose-fill insulation bags, which are breathable and can be easily laid across joists. If you’ve got a large loft, you should use three walk boards.
