At a time when we are all trying to save money on our domestic and commercial heating bills, whilst at the same time trying to be as energy efficient and environmentally friendly as possible we need to look upwards, to the roofs of our Devon properties, to see whether they are working as efficiently as possible. The most obvious deficiency in a roof, for the purposes of energy efficiency and environmental friendliness, is the lack of any insulation. Because heat generally rises, the roof is the last defence barrier against heat loss so it is essential that it is properly equipped to act as such. In this article we look at the issue of roof insulation and describe how easy it is for your local roofers to protect your home against heating loss and spiraling fuel bills.

Roof Insulation

Roof insulation, or loft insulation, is an integral component of keeping a building energy efficient. Effective roof insulation is estimated to reduce your energy bills by as much as 15-20%, meaning that the installation costs can very quickly be recovered, often within only a few years. Although some people are willing to install their own loft insulation, it can be quite an arduous, uncomfortable task and many home owners consider that it is best left in the hands of professional roofing contractors. The availability of grants to assist in defraying the costs of roof insulation are an added incentive to employ a team of local roofers to carry out the work! 

Types of Roof Insulation

Blanket Insulation

Blanket, or quilt, roof insulation is easily the most frequently employed. The blankets are manufactured from glass fibres which are commonly made through the recycling of used glass bottles. The insulation is installed by laying rolls of the insulating material between the joists of the roof. It is likely that the rolls will need to be cut to fit the gaps between the joists as the width of these do vary from building to building. It is recommended that the insulation should be 27 cms deep. Because joists do not tend to be of that depth (they are usually 10 cm) it is usual to fill the cavity between them with a insulating material that is the same depth as the joist, with the remainder being laid across the first layer to take the insulating material up to the required depth.

Other Types of Roof Insulation

Sheet Insulation

Unlike blanket insulation, sheet insulation is not laid on the floor of the roof void. Instead, it is used to insulate beneath the slope of the roof. This type of roof insulation is most frequently found in loft conversions and it is conventionally covered with a layer of plasterboard.

Brown Fibre Insulation

The installation of brown fibre insulation is definitely one that we would advise should be left in the hands of professional builders or roofers. The process involves blowing the insulating material, which normally consists of fire resistant recycled paper or wool, between the joists. Because it involves no cutting it is quicker than blanket insulation but it is not suitable if it is intended that the loft is to be used for any practical purpose such as habitation or storage.

Precautions
If you decide to go ahead with roof insulation without employing professionals there are certain mattes that should be borne in mind. Firstly, the materials that are employed in roof insulation often act as irritants to the skin, eyes, throat and chest, especially in a poorly ventilated, dusty roof space. It is important to carry out the task in long clothing and to wear gloves and use a dust mask and, to prevent the material getting into the eyes, a set of goggles. Caution should also be taken when walking around the roof space and to avoid the risk of damaging the ceiling below it is prudent to use a plank to move around the loft space rather than walking on the narrow joists.

Summary

If you want the most cost effective way of insulating your home, roof insulation is certainly the first thing to consider. Whether you do it yourself or, hopefully with the assistance of a grant, employ professionals, it is bound to save you money in the long term.
