These fibreglass loft insulation rolls by Knauf insulation are environmentally friendly, and lightweight with pre-cut perforations. They are specifically designed for use in cold lofts, where pitched roofs are insulated at ceiling level. The open-cell nature of these fibreglass insulation rolls traps heated air, using its many tiny spaces, thus effectively reducing heat loss through roofs. Knauf loft Insulation rolls are partially cut that enable easy installations in between joists.
Manufactured using a sustainable, unique ECOSE Technology, they are designed to increase site efficiency. These fibreglass loft insulation rolls offer exceptional fire resistance, thermal and acoustic insulation. Knauf loft insulation is lightweight. resilient and durable. The fabric of glass mineral wool does not contain any organic material, hence fibreglass loft insulation does not promote the growth of fungi, mould or bacteria. It is odourless, rot-proof and non-hygroscopic.
Generally speaking, insulation rolls are cheaper, easier to install and easier to handle. However, they may not have as good thermal or acoustic insulation properties as insulation board like PIR and phenolic. Even mineral wool boards tend to be denser and therefore offer better properties than insulation on a roll. However, they are a great starting for DIY and tradesmen alike and fit to most peoples budget.

Knauf Loft Insulation Roll
In most cases, we think of insulating or upgrading the insulation in the loft first. It is estimated that we lose nearly 25% of warm or heated air through lofts and hence using top-quality loft Insulation is a must. This is where the Knauf Fibreglass Loft Insulation roll comes into play.
At Buy Insulation Online, we stock Knauf loft roll 44 at very competitive prices. All orders of Knauf Loft insulation above £455 Ex.VAT are delivered for free. Plus, for every order, we protect 5 trees in the amazon and also plant a tree in your name, for free.
Knauf Loft roll 44 is a fibreglass loft insulation roll that ensures high thermal efficiency in your loft area. Here are some reasons why Knauf Loft Roll is one of our top-selling products:
Thermal Conductivity:
With a low thermal conductivity of 0.044 W/mK, this fibreglass insulation roll traps heat in its fabric. This means it does not allow or restrict the transfer of heat. This converts to low energy bills, saving money.
With Knauf loft Insulation effectively trapping heat, your heating system and radiators will not have to work exhaustively to retain heat.
Fire Resistance:
Knauf Loft roll is rated A1 by Euroclass. That means the insulation is non-combustible in nature. Loft Insulation on a roll gives you extra security as they are non-combustible and do not contribute to fire in any way.
Make:
Knauf loft insulation is made using superior-quality fibreglass. Whatsmore, Knauf uses its very own unique bio-binder-based Ecose Technology to make these insulation rolls.
Product made with Ecose Technology and made with responsibly sourced materials. The manufacturing process is nearly 70% less energy-intensive. They do not contain or release any harmful gases that can harm you or the environment in any way.
Water-Resistant:
Knauf loft insulation is water-resistant and breathable in nature. It allows vapours to pass through their fabric easily, which helps keep condensation or any other moisture-related issue away.
Easy to install:
Knauf loft rolls are 1140mm wide and hence enable a perfect fit between ceiling joists. You can simply cut these loft insulation rolls to size and roll them onto your loft floor. Installing oft insulation may be a DIY task, but only try it if you are a competent DIYer. Also, follow the required safety protocols while installing loft insulation.
For insights on Knauf loft insulation installation, you can check out the Installation guidance on this page.
Since the Knauf loft roll is made using Ecose Technology, the installation process does not release as many harmful fibres like other fibreglass loft insulation can. Knauf loft roll is also easy to work with and softer to touch.
Environment:
Loft Insulation roll by Knauf is an environmentally friendly product. The insulation itself is made using nearly 70% recycled glass. Loft rolls do not release any gases that have a global warming potential or ozone-depleting potential.
