There are a variety of loft rolls on the market, and the type you choose will depend on the insulation you need. The Earthwool Loft Roll 44 is an excellent choice for a glass mineral wool roll, as it is fire rated Euroclass A1, odourless, and non-hygroscopic. To learn more about this product, read on. This article will explain the advantages of this material and what you should look for in your next loft insulation project.
Earthwool Loft Roll 44 is a glass mineral wool roll
The Earthwool Loft Roll 44 is a glass mineral wool roll with an 1140mm width, a partially perforated backing, and a non-combustible binder. It is an excellent thermal insulator and is odourless, mould and fungus-free. The Earthwool Loft Roll 44 is certified by Bureau Veritas. It can be used in both lofts and attics.
This insulating material is primarily used for the ceiling of pitched roofs, but is also ideal for floors. Earthwool Loft Roll 44 is generally laid in two layers at the ceiling level, ensuring that it is flush with the joists. It is suitable for both suspended timber floors made of steel or concrete joists. The Earthwool Loft Roll 44 has a thermal resistance of 3.40 m2K/W and a thermal conductivity of 0.044 W/mK. It also has a fire rating of Euroclass A1 to BS EN 13501-1.
ECOSE Technology is a patented, bio-based binder that is used in the manufacturing of Earthwool. Its manufacturing process is stress-free and the customer service team at Trade Insulations is excellent. Before laying the roll, be sure to check for heavy-duty electrical wiring. Keep it at a height of 75mm above the insulation. Ensure there is no downlights, hot flues, or electrical wiring underneath. Ensure that there is a minimum 75mm clearance and wear gloves while installing the roll.
It is fire rated as Euroclass A1
If you are looking for a loft roll, the Euroclass A1 rating will be your best bet. This rating is used to differentiate between combustible and non-combustible products, and is a legal requirement. Products achieving Euroclass A1 or A2 are non-combustible. Manufacturers are legally required to report this information in the DoP for their products.
Its fire rating is equivalent to BS EN 13501-1 and SANS 428:2012, and is also available in different finishes. The rating for stone wool insulation is A1. The material is fire resistant, and meets all of the requirements for Euroclass A1. It can also be rated as ‘Limited combustibility’ for added safety. And the best part is, Euroclass A1 loft roll is also highly affordable.
The European Reaction to Fire rating of insulation materials is used to help specifiers and building owners understand the potential risk of fire spread and development. The vast majority of insulation materials are non-combustible, so the Euroclass A1 rating means they will help minimise the risk of fire development and spread. Fire resistance is an indicator of how well a building withstands fire. However, it doesn’t guarantee that it will remain that way in a fire.
It is odourless
Knauf Loft Roll 44 is a thermal insulator with a thermal conductivity of 0.044 W/mK. Its partially cut perforations are used between joists at 600mm centres. It is odourless, non-hygroscopic, and a vermin-free material. It is ideal for both new and retrofitting buildings. It can also be used as a floor covering, as it is suitable for both indoor and outdoor use.
Earthwool Loft Roll 44 represents zero known threats to the environment. It is odourless and non-hygroscopic, and poses no known threat to vermin, fungi, or bacteria. The product also offers negligible resistance to water vapour. Its vapour resistivity is only 5.00MNs/g.m., which is negligible when compared to other insulation materials.
It is non-hygroscopic
Loft Roll is a type of insulation that is odourless, non-hygroscopic, and rot-proof. Due to the non-hygroscopicity of the roll, it does not support the growth of fungi, bacteria, and mould. Moreover, it does not sustain vermin or other pests. Its unique properties also make it a green material that is beneficial to the environment.
Hygroscopic insulation reduces the risk of condensation and mould by releasing water vapour slowly when the humidity level drops. Hydrophobic insulation is water-resistant, whereas non-hygroscopic insulation does not absorb water vapour. However, it is important to keep in mind that both types of insulation are prone to damage by prolonged exposure to moisture. Thus, it is important to choose the best type of insulation depending on its application and location.
It is easy to handle
A loft roll is an affordable, lightweight way to insulate a loft without the expense and hassle of a professional installation. These rolls are easy to handle, but they must be carefully examined for signs of rot and deterioration. When installing a loft roll, you must also consider whether any electrical wiring, cables, or hot flues are present and adjust accordingly. You should also wear appropriate clothing and crawling boards if you are working on a high ceiling.
It is cheaper than rigid insulation boards
Despite being a little more expensive than rigid boards, loft roll is a cheaper option for insulating the rafters and joists of your loft. While the former is also available in a rigid form, it does not have the same environmental benefits. In addition to being cheaper, rigid boards also have good thermal qualities despite their half-thickness. This makes them ideal for loft insulation because they can be easily cut to size and are easy to install around light fittings and studs.
If you’re comparing loft roll with rigid boards, you’ll be able to compare the cost per square foot and R-value. For most applications, loft roll will be the cheaper choice. However, the EPS board is a better choice for below-grade applications. Its insulating value is consistent, unlike XPS, and it has a higher R-value per inch. However, this insulation doesn’t have the same fire-resistance as rigid boards, and it’s more expensive too.
When it comes to rigid boards, it’s important to get the measurements right. It’s best to visit a DIY store to get your measurements right, but if you want to save even more money, you can always shop online for these products. Purchasing rigid boards online can save you even more money, and you’ll find that these materials come in a variety of thicknesses ranging from 20mm to 40mm.
It is not suitable for lofts with difficult access
Those who live in difficult-to-access lofts should use specialist products. A standard loft roll is not suitable for this type of loft, so a professional must be used to install the insulation. Depending on the size of the loft, a professional installation can take from a few hours to a few days. A professional will need access to the loft and specialist equipment to blow the loose insulation into place.
Rigid boards are also available to insulate lofts. Rigid boards are slightly more expensive than loft rolls but they have the same thermal properties as mineral wool. Rigid boards are usually less than half the thickness of loft rolls, so they are not suitable for lofts with difficult access. However, if you have a loft with poor access or a difficult landing, you may want to use a rigid insulation board instead.
Blown-fibre insulation is another alternative to loft roll. This product is more expensive and requires professional installation. Many older homes are not equipped with loft insulation and are only fitted with blown-fibre insulation at the level of the joists. Top-up loft insulation can make a considerable difference to energy bills. You can purchase a specialist insulation kit and get a professional to install it for you.
