Energy Care - Cavity Wall and Loft Insulation

Technical
If your home was built before 1935, the walls may not have cavity or they may not be suitable to insulate.

Having cavity wall insulation installed couldn’t be easier. It is normally applied from the outside through small holes approximately the size of a 10 pence piece which are drilled approx 1.4 meters apart all across the external walls. The insulation material is then injected through the holes, filling the cavity. The holes are then filled in to make as perfect match as possible with the existing wall.

It’s a simple process and is normally completed within 3 to 4 hours, without damage or mess to your garden.

The insulation material used is white wool mineral fibre, which is blown in to cavity by air pressure. Installation is dry wall product and is not mixed with chemicals or solutions. The system has been tested, assessed and approved by the British board of Agement.

The material is guaranteed for 25 years against any defects (guarantees are provided by the Cavity Insulation Guarantee Agency – CIGA).

Installation
Before the installation, the installer will undertake a survey of your property to confirm that it is suitable for insulation.

The drilling process does create some vibration – so it is recommended to remove any pictures ornaments from the internal side of your external walls, for their safety and your peace of mind.

The installer will need access to all walls, so he will need to get inside attached garages, lean to sheds, conservatories, etc. If you have a wall right on the boundary, you will need to liase with your neighbour as the installer will need to go into their property.

The drilling process inevitably creates a little dust but this will be cleared by the installer at the completion of the job. It may, however, be wise to remove vehicles from the drive and things close to the walls.

Depending on the type of the heating appliances in your home it may be necessary to install a permanent ventilator to the outside air if none already exist to ensure there is adequate ventilation, usually where there is working solid fuel appliance and in some types of gas and oil fires.

The surveyor will always advise whether or not any additional ventilation is required. Where additional ventilation is considered necessary this will typically involve fitting a 5 inch plastic air vent and the surveyor will advise where the vent(s) need to be installed.

How do I know the walls are full? The system has defined pattern of holes, which has been tested to verify that it results in a complete fill. The machine has automatic cut out, which actuates when the adjacent wall area is full. There is tolerance in the injection pattern so that the material will flow past the next injection hole.

Loft Insulation
The current recommended standard requires 250mm (approx 10") of loft "insulation.

Our specially negotiated prices include the lagging of all cold water tanks and pipes in the loft and insulating and draft proofing your loft hatch. The insulation is quick and simple to install and can usually be completed within a couple of hours.

The insulation used by the Energy Care is a mineral wool material and is laid between the joists with additional layers cross-laid at right angles to ensure there are no gaps at the top of the joists.

Up to 25% of the heat produced in your home is lost through your roof if the loft is not insulated.

Loft insulation is a very effective way to reduce your fuel bills since it acts as a blanket trapping heat rising from the living space below, and can save you on average £205 off your annual fuel bill.
