Our high-quality sheep’s wool loft insulation will save around 10% on your heating bills. While sloping ceiling insulation is a canny way to thwart heat loss in difficult-to-insulate areas.
Eco-friendly sheep’s wool loft insulation
We install Thermafleece loft insulation made from sheep’s wool. This excellent loft insulation provides significant heat insulation, keeping your period property toasty in winter and saving on your fuel bills.
Thermafleece is a natural and eco-friendly material that has many beneficial properties. It has a 60-year life compared to 15 years for glass wool, and an increase in insulation properties in damp conditions. It’s treated with natural borax to prevent damage from pests and it won’t irritate your skin or respiratory systems. It also supports British sheep farmers – improving economic resilience – and uses little energy in its manufacture.
When we insulate your loft we can also install the unique Loftzone flooring system, which means you can still store heavy items in your loft.
Our innovative secondary glazing and insulation solutions are well suited to preserving Surrey’s celebrated Victorian architecture, fine examples of which can be found in areas such as Woking, Guildford, Walton-on-Thames, Ewell, Esher, Camberley, Redhill, Leatherhead, Epsom and Weybridge plus other areas in this magnificent county.
Sloping ceiling insulation
Sloping ceilings in upstairs rooms have very high heat loss per square metre. This is because they usually consist of a sheet of plasterboard, a 100mm ventilated gap between the rafters, then battens, felt and tiles.
If you compare this to an 18-inch wall or 12 inches of loft insulation, it becomes clear how little insulating effect they have, making them responsible for the coldness you’ll often find in these rooms. As a minimum of 50mm ventilation is required between the rafters, taking down the plasterboard to insulate behind a sloping ceiling is very expensive and disruptive for little gain. However, there is another solution.
Our sloping ceiling insulation consists of thermal laminate boarding, a high-efficiency insulation board with plasterboard attached. This is applied underneath the sloping ceilings by screwing through to the rafters.
Gaps around the edges are then filled and the whole area re-plastered. Because the extra material costs a little more, 100mm thickness is recommended wherever possible. However, if you are limited on headroom, 50mm is still effective.
Since this is labour intensive due to the plastering, sloping ceiling insulation is generally more expensive than our draught proofing, loft insulation and secondary glazing. It does however offer an attractive return on investment in terms of money saved on heating bills. This is typically in the region of 10% return per year. So if you have covered the other areas first, this is a very attractive next step for warmth, efficiency and money saving.

Loft insulation works by creating a thermal barrier that reduces the transfer of heat between the inside of a building and the outside environment. It’s usually installed in the loft or attic space, directly beneath the roof. The primary goal of loft insulation is to improve energy efficiency by minimising heat loss in the winter and heat gain in the summer.
Insulating your loft is a fantastic way to reduce heat loss in your property. The insulation acts as a barrier, helping to retain the warmth generated within your home and reducing your energy bills. It helps to maintain a more consistent and comfortable indoor temperature, reducing the need for heating in the winter and cooling in the summer. An energy-efficient home with proper insulation is often more attractive to potential buyers and therefore may contribute to an increase in the value of your property.
The amount of energy you can save by insulating your loft depends on various factors, including the existing insulation, the climate where you live, and your heating habits. On average, it’s estimated that a well-insulated loft can result in energy savings of up to 10% on your heating bills.
The specific energy savings will vary, but loft insulation is generally considered a high-impact, cost-effective measure to enhance the energy efficiency of your home.
Draughts (or air infiltration) are often one of the biggest sources of heat loss in a building. In a typical ‘unimproved’ period building (one that has not had modern insulation measures applied) we estimate the draughts cause approximately 30% of total heat loss. To accurately measure the sources and rate of draughtiness (or air infiltration) an air pressure test is required.
However, most occupants know where the draughts come from and where they are worst because they can feel it! Windows, doors and chimneys will normally be responsible for the majority of the draughts. Mitchell & Dickinson’s surveyors will help you identify the draught sources and their contribution to your building’s thermal performance.
Yes, damp is caused when insufficient insulation leads to temperature differences between the indoor air and the loft space. When warm, moist air from inside the house comes into contact with the cold surfaces in the loft (such as the roof or walls), it may lead to condensation. This can contribute to dampness and create an environment conducive to mould growth.
Good quality loft insulation and adequate ventilation is crucial for maintaining a balanced moisture level in the loft space. Without proper ventilation, dampness may become a problem.
There are several different types of loft insulation available, including fiberglass insulation, mineral wool insulation, cellulose insulation and reflective foil insulation. One of the most eco-friendly types of loft insulation is made from natural sheep’s wool.
This natural and eco-friendly material has many beneficial properties including a 60-year life compared to 15 years for glass wool, and an increase in insulation properties in damp conditions.
Products such as Mitchell & Dickinson’s eco-friendly sheep’s wool loft insulation are treated with natural borax to prevent damage from pests, are not irritating to skin or respiratory systems, support British sheep farmers – improving economic resilience – and use little energy in manufacture. Sheep’s wool insulation is also biodegradable, reducing its environmental impact at the end of its lifecycle.
While it is possible to install loft insulation yourself, it’s often worth hiring a professional to ensure it’s installed correctly and effectively. They will be up to date on the latest building regulations and will have the correct specialised equipment to complete the job. They’ll also have knowledge of achieving the desired thermal resistance and understand the required density and thickness of the insulating material.
