Solid Wall Insulation

What is Solid Wall Insulation?
If your home was built before or around 1920, its external walls are likely to be solid rather than Cavity walls. Cavity walls are made of two layers with a small gap or cavity between them. This cavity acts as a barrier to reduce heat flow through the wall. Solid walls have no such gap and this allows more heat to pass through them than through cavity walls. In fact, twice as much heat can be lost through an un-insulated solid wall as through an un-insulated cavity wall.
The good news is that, like cavity walls, solid walls can be insulated from the inside or the outside.
The benefits are as follow:

  • - Improved insulation levels lead to a reduction in heat losses and therefore to a reduced energy demand for heating in the winter months.
  • - Higher levels of insulation help to reduce building overheating in the summer months, thereby reducing the energy demand for cooling.
  • - Reduced energy demands result in lower CO2 emissions.
  • - Interstitial or internal condensation on walls can be eliminated, and the attendant problems of damp internal surfaces and mould growth are overcome.
  • - The building fabric can be protected against the effects of the weather by the insulated cladding.
  • - The building structure is protected from daily environmental temperature changes. Fluctuations in internal temperatures are reduced, leading to more comfortable living and working conditions.

  • All our External Wall Insulation installations are covered by an independent guarantee.


    What does a solid wall looks like?
    Until the 1920s most buildings had solid walls rather than cavity walls. They could be built in brick or stone with the wall thickness dependent on the building height. Solid walls are approximately 215mm (9inches) thick. Cavity wall insulation

    English bond is easy to recognize because it consists of a course of headers followed by a course of stretchers. Although the bond was very common in the Victorian period it was not generally used for houses, but was used in factories, stations and retaining walls etc. It's a very strong bond but probably not as attractive as Flemish bond. Our surveyor will help you identify the type of walls, as well as the best way to insulate them.

    Why is it important to insulate my solid walls?
    The Government regards solid wall insulation as one of the most effective cost and carbon saving measures that you can carry out on your property - which is why they are encouraging home owners who have solid walls to take advantage of current installation schemes.

    Without solid wall insulation, your wall allow heat to escape very easily. You will probably have noticed that shortly after you turn down your heating (gas, electricity, oil) your rooms begin to feel cold. Because of this you turn up your heating, probably even higher than before, to make the temperature more quickly more comfortable. The result? You use more fuel - hence higher utility bills! Depending on the size of your house and with current high fuel prices it can easily be £££+. Uninsulated solid walls can lose up to 45% of the heat generated within the property. So for an uninsulated house that's £1 of heat escaping for every £4.5 spent heating it.

    How are solid walls insulated?
    Internal wall insulation is usually done by building a stud wall filled with insulation, or mechanically fixing insulated plasterboards to the existing walls if in good conditions.

    External wall insulation involves fixing a layer of insulation material to the wall (usually PIR insulation boards), then covering it with a special type of render or cladding. The finish can be smooth, textured, painted, tiled, panelled, pebble-dashed, or finished with brick slips.

    The external wall insulation process is as follow:
    Scaffolding is erected if your property exceeds one floor. Our installers will remove fittings such as rainwater pipes, satellite dish etc. We then prepare the surface for our insulation system, applying fungicidal wash to ensure surfaces are clean and ready for application of our system. We then install insulation boards, complete with associated trims which are applied to external wall areas. A base coat of render is then applied on top of the insulation boards. This includes reinforcement mesh - this then has to be left to dry, typically 2-3 days. Once the base coat render is dry we apply a suitable decorative finish render, this can be; acrylic, silicone, dash or brick finish. This again requires 2-3 days drying time. Any items removed from walls (rainwater pipes, satellite dish etc) are then re-attached. Scaffolding is taken down and the area around your property is cleaned. We then have a final inspection by the system Inspector to check the job reaches our high standards. Once the homeowner is happy with our installation we then apply for a guarantee, which is issued by the manufacturer of the system.


    How long does it take?
    An installation may take up to 3 weeks including erection and dismantling of any necessary scaffolding. Render and finishing processes are weather dependent, and may be delayed in very cold weather, rain or very hot weather.

    How much does it cost?
    Costs will vary between £5000 to over £14000, depending of the size of your property, type of finish ect.

    Guarantee
    Once the work is completed and payment is made, you will receive a 10 years Guarantee Certificate (insurance based). The Guarantee should be kept in a safe place as it may need to be produced in the event of a claim or if you sell your property. The Guarantee is passed on to any new owners of your home and Solid Wall Insulation will be mentioned to anyone purchasing your property as required by the Home information pack and energy efficiency surveys, as well as the associated fuel and carbon cost savings.

    Solid Wall Insulation will make your property more attractive to prospective buyers since energy efficient homes are more and more taken into account in the valuation process.

    More loft insulation but less storage space?
    Insulating your loft is great and have many benefits, however storage space is often reduced substantially as a result.

    For a minimum outlay, we can board your entire loft, or just a section of it, gaining invaluable storage space, without compromising on the insulation thickness in the loft.
