Attic Insulation

Some people refer to the void space under a roof as either an attic or a loft. This space is usually above the main occupied spaces, however, it is still accessible. It is in the attic (or loft) that a lot of heat is lost in a building. This is why it is important to insulate an attic to trap heat and therefore keep a house warm.

The government state that there are differences between a loft room and an attic room, however, the type of insulation required to insulate a loft or attic is the same (depending on the space itself) Typically a loft is accessed by a fixed staircase and has the area converted as a living space. An attic is also accessed by a fixed staircase, however, it has the eaves area of the loft squared off to create a box room at the centre.

At Trade Insulations, we stock loft and attic insulation and are able to deliver nationwide. Placing an order is easy. Simply choose the product you require, add it to the basket and check out using our secure checkout.

What are the different types of loft insulation

There are many different brands of insulation to choose from when insulating your loft or attic space. You will find top brands on our website such as Knauf, Celotex and Rockwool. In addition to the brands, there are different types of loft insulation depending on the application. One of our biggest selling loft insulation products is the Knauf Loft Roll 44, however, we have left a breakdown of each type of loft insulation below to help you make your decision when purchasing.

Did you know that as much as 25% of heat loss in a home occurs through the roof of a building? A lot of people do not realise how effective loft insulation can be at insulating a home. Studies show that the average house could save £200 a year by just insulating an attic or loft space. Loft insulation is crucial as it can help reduce the amount of heat that is being lost. Check out our article on how loft insulation can prevent heat loss for a more in-depth look at this.

Loft Insulation Boards

Loft insulation boards are available from a thickness of 20mm up to 200mm. They are available in 2400mm x 1200mm and have total coverage of 2.88m2. There are many products to choose from such as Celotex’s thermal bridging PIR boards or even Kingspan TP10, which is a pitched roof insulation board. Kingspan TP10 Board is ideal for creating a warm loft as it can be used to insulate both ventilated and unventilated roofs. Celotex PIR boards can be used to reduce heat escaping through studs. In addition to this, Celotex Insulated Plasterboards are often bought for the purpose of insulating a loft. Loft insulation boards are primarily used to insulate the underside of a roof to prevent heat loss.

Loft Insulation Rolls

Loft rolls are commonly made from glass or mineral wool. This is because glass and mineral wool are great insulating materials. You may hear people refer to this as fibreglass insulation. The fibres can trap air, which can lock in heat. Knauf Loft Roll 44 is popular due to its ease of installation. It is also combi cut, which means it is pre-perforated so that it can be cut to suit the application. A popular alternative to Knauf’s loft roll is Isovers Spacesaver Loft Roll. Loft roll is installed and can be rolled out and fitted between joists. The second layer of the loft roll can then be added at 90 degrees to the first layer and ceiling joists. Rockwool is another popular manufacturer of loft roll.
Loft roll insulation is also called blanket insulation and is an easy and cheap way to insulate a loft or attic. For warm roof insulation, you would need a combination of loft board insulation and insulation between the joists (loft roll or batts)

Loft Roll Frequently Asked Questions

Below we have outlined some frequent questions that we get asked about loft roll insulation.

How are loft rolls manufactured?

Loft rolls are made from mineral wool or fibreglass. Fibreglass is also referred to as glass wool and has excellent insulative properties. Fiberglass wool is manufactured by heating fine fibers of glass and sand. The molten sand and glass are then spun through an ultra-fine mesh. Binding material is added and then the mixture is cooled to give it a wool-like texture. This process is quite similar to how candy floss is made. The blend of materials is then further heated and calendared to give it strength and stability. This clever manufacturing process traps pockets of air between the glass. It is the pockets of air which help the product achieve high thermal performance.
You can find glass wool insulation on our website from brands such as Knauf and Isover. A lot of insulation companies are now also using recycled glass to manufacture fibreglass insulation rolls, which makes them environmentally friendly.

How To Cut Loft Rolls?

There are several ways that you can cut loft rolls. Loft insulation rolls can be easily cut using a utility knife or carving knife. In addition to this, loft roll can also be cut with shears. We suggest that you mark your measurements on the roll before you make any cuts. Some products such as Knauf Loft Roll 44 even come combi cut, which gives you greater flexibility on your installation. Remember that loft rolls can produce dust when cut. They may also be an irritant to the skin and eyes so wear appropriate PPE to counter this.

How many loft rolls would I need for my loft?

The amount of loft roll required is dependent on your loft space and the area it needs to cover. You can work out the area of your loft by measuring the width and length of the space in meters. When you multiply these figures together, it will give you the m2 area coverage.
All of the products on our website have the total coverage in m2 outlined on the product pages to make it easy for you to work out how many packs you need. We do advise that you order 10% more than you require for wastage. It is always better to be a little bit over rather than short. If you are layering the product up then make sure you account for this. If you do need help when ordering then do not hesitate to get in contact with us. Our friendly team can help assist you in finding the perfect product.

Why are your loft rolls so cheap?

We sell big volumes of loft insulation roll, which means we can pass our savings on to you. With us, you do not need to be in the trade to benefit from trade prices.

This is why you will find cheap loft rolls on our website. Helping you save whether it's a small DIY job or a large-scale development project.

Do loft rolls have acoustic properties?

Loft rolls can be used to effectively reduce noise pollution. We sell standard loft rolls as well as acoustic rolls on our website. Acoustic loft roll can be used in partition walls, roofs, floors and ceilings to reduce sound. Isover Acoustic Partition Roll is a popular loft roll which has outstanding acoustic properties.

What is the difference between Knauf and Isover Loft Roll

Knauf and Isover are both highly regarded companies when it comes to loft insulation rolls. Knauf Loft Roll 44 and Isover Spacesaver Roll are very similar in specification. Both loft rolls have a thermal conductivity of 0.44 m/Wk. Isover Spacesaver Loft Rolls have slightly more coverage across thicknesses and also are slightly denser. Both products have a Euroclass A1 rating, which means they are both classified as non-combustible. Knauf Loft Rolls and Isover Loft Rolls are made from glass mineral wool and are both pre-perforated for greater flexibility. You can find detailed specifications on our product pages, however, the products are very similar.

How thick should loft insulation roll be installed

UK current regulations state that blanket insulation should have a total depth of 250mm to 270mm when used in a loft or attic space. This can be achieved by layering the loft roll to meet the current regulations. It is worth noting that previously the UK building regulations stated that 200mm was the recommended depth. Older properties may also only have a depth of 100mm, which means they should be upgraded to meet current standards. Low blanket insulation depth means that less heat can be trapped and therefore it does not benefit from full insulative qualities. Some property developers may not be aware of new building regulations introduced in June 2023, which means that properties will have to perform better in terms of energy efficiency. Installing loft roll can help property developers to conform with this.

Loft Insulation Between Rafters

This is the insulation that is fitted in between the rafters of a roof. Most often people use insulation boards or mineral wool to insulate the rafter space. On our website, you can find loft insulation (between rafters). Ceiling insulation can be combined with rafter-level insulation in an existing converted loft space.

The benefits of insulating a loft

There are many benefits to insulating a loft, which we have outlined below.

  • It reduces the energy needed to warm a home by preventing unnecessary heat loss
  • Loft insulation installs can lower your carbon footprint
  • It can lower energy costs
  • A loft insulation install improves the energy efficiency of a property
  • It can increase the value of a property
  • Loft insulation can prevent water pipes / tanks from freezing
  • it creates a barrier to trap heat

Heat rises, which means heat can be lost through the roof. Loft insulation will prevent heat from escaping through the roof. It keeps your property warmer in the winter and cooler in the summer. These components will make your living or working space a more comfortable environment and can result in lower monthly energy bills. Installing the correct insulation required for your building can also improve energy efficiency. Specific loft insulation materials can also be provided for moisture resistance to prevent mould or rot and other insulation materials can increase safety by improving fire resistance. Mineral wool is great for use in lofts or attics as it is classed as non-combustible. In addition to this, it is lightweight and easy to install.

OVOenergy has kindly put together a guide to loft insulation, which details the full pros and cons of different types of loft insulation.

How much loft insulation do I need?

To find out how much insulation you need, you need to work out the area coverage for your loft space. Multiplying your width and length will give you the area coverage for the space. Most loft insulation boards have an area coverage of 2.88m2. Loft rolls may differ depending on the product itself. Our website includes full coverage information on each product so you can work out exactly how much you need. It is always better to order more loft insulation rather than less. Loft rolls should be layered, which means you may have to order double to achieve the required depth. If you need help ordering loft insulation, get in touch with us and we can help.
