 Does External Wall Insulation Work

Does external wall insulation work? That is the most important question if you are considering this method of home improvement. Political parties of any flavour make some sweeping promises around election times, but even the least cynical of UK voters have long since accepted that talk is cheap. 

Many householders will be wondering less about when flying pigs will deliver those energy price caps, and a lot more about how to find ways to save on those energy bills. Home Logic Wall Insulation may well offer some down to earth practical answers. So, does external wall insulation work? Let’s find out!

How Does External Wall Insulation Work?

If wall insulation conjures up images of drilling rigs or boring holes in your home, before pumping them full of chemicals, then think again!

Home Logic Wall Insulation is an innovative product that is a spray-on solution which has two distinct advantages; it requires minimum disruption to your home and, as a spray-on solution, it’s both quick and easy to apply.

Both of these factors also make the product a comparatively affordable method of insulating your home and reducing your energy costs.

This fast acting spray-on product utilises the latest Nano-technology, chemically bonding to a range of building materials – including concrete, brick or stone.

The spray bonds with these materials, and protects against water absorption – a crucial factor for preventing heat loss from buildings. Most building materials are naturally porous, which in simple terms means that they contain pockets of air.

Over time, these pockets absorb water which, in turn, conducts heat wonderfully! Unfortunately, this tends to be from the inside of your home to the outside, increasing the amount of heat loss by a startling amount.

The Cost of Damp Walls

Most properties have several ways in which all that hard-earned heat we put into them can be lost.  External walls and the roof of a building are by far the biggest culprits.

However, heat lost through water retention in the fabric of the structure has been one of the hardest problems to combat, until recently. Even in homes that have been well insulated up top, the amount of heat lost through the walls can be a serious drain on your household budget.

Regardless of whether your walls are cavity walls (with an air-filled cavity between two ‘skins’ of brickwork) or solid walls, moisture that naturally builds up over time will reduce the building’s overall thermal resistance.

The amount of heat loss in a building will be affected by a range of different factors. The construction of the property and the materials used are the main ones, but the amount of moisture in the walls is the one that is most likely to induce an unexpected over-draft.

Thermal resistance in damp walls can be up to 50% less in walls that have a content of only 5% moisture content. Yes, that was 50%. Ouch! Now you understand, even more so than before, the importance of the question – does external wall insulation work?

Small Scale Super-Hero?

To reduce thermal conductivity (heat loss) in walls, the basic principle is to find ways to limit the moisture content in the structure of your home. Home Logic Wall Insulation is one of the most effective products on the market when it comes to reducing water absorption.

So much so, in fact, that it could be considered something of a super-hero – saving the planet by reducing your energy costs and therefore reducing energy consumption.

The product can reduce water absorption in a range of building materials by up to 95% – the benefit being fairly self-evident.  By reducing the amount of damp in external walls, you will reduce the amount of moisture building up in those micro-air pockets, and increase the thermal resistance of your home.

The more heat retained in the fabric of the building, the less you have to pump into it, making the property far more energy efficient overall.  Ultimately, this means that you get more use out of the heat that you buy than you would in a non, or partially, insulated home.

Balance and Breathability

Most building materials need to be able to breathe – put simply, they need to allow moisture to evaporate. Home logic Wall Insulation is fully compatible with this requirement.

The product bonds with the surface, and resists rain, algae and dirt, but still allows brick, stone, concrete and other materials to ‘breathe’ naturally.

Buildings that are well insulated, but can breathe properly, have the best of both worlds and the product creates buildings with a perfect balance of thermal conductivity (allowing moisture to escape) and thermal resistance (reduction in heat loss).

Insulation with Benefits

OK, so reducing your energy consumption and your energy costs are the two greatest benefits of Home Logic Wall Insulation, but there are even more perks to be had!

As already mentioned above, the application process couldn’t be simpler or less disruptive. On most properties the spray on technique means that the work can be completed extremely rapidly and with little – actually no – disruption to your daily routine.

In addition, this type of wall insulation provides yet more friendly benefits. These benefits settle any doubts to the question – does external wall insulation work?

The product protects against rainfall – this has the added advantage of keeping your walls free from the effects of weathering. Creating a barrier against the elements improves the appearance of external walls, and also protects against corrosion from pollutants.

Cracks and gaps in the stonework of the exterior are filled, reducing their visual impact, and also reducing draughts – in turn helping with those energy costs yet again.

Home Logic Wall Insulation also creates a self-cleaning layer to the exterior of your home. As rain is unable to penetrate the masonry of the structure, it carries away dirt and grime, effectively eliminating expensive cleaning and maintenance bills.

Cleaner walls mean less bacteria, which is one of the main causes of unsightly and difficult to remove algae – this spray on solution means no more algae!

Planning Permissions?

For external wall insulation, there is no single answer to the question of planning permission. In most cases, you need not apply to your local authority to have Home Logic Wall Insulation installed (or sprayed) at your home.

However, it’s worth double checking with your local planning authority to be absolutely sure before you have the work done. Some properties may require permission or may need to comply with building regulations.

If any work undertaken to the exterior of your property that will change the appearance of that property you may need planning permission. This is most likely to be the case in protected areas or on protected buildings.

Listed buildings will normally need permission for any changes – though factors that can impact this include what part of the property is listed. For listed buildings it’s essential to contact your local Listed Building Officer to discuss your plans in advance.

Home logic Wall Insulation usually improves the look of the exterior – keeping it clean and fresh for years – but should not normally change the exterior substantially.

Properties in protected areas may include those in conservation zones, National Parks or Areas of Outstanding Natural Beauty (AONBs). If your home falls into one or more of these categories it is, again, always sensible to seek advice from the relevant authority or officer.

All Systems Go? Here’s What to Expect

OK, so you’ve decided that a spray on wall insulation is for you? And now you also know the answer to – how does external wall insulation work? So what should you expect from a reputable supplier?

The following list explains the process that should be completed in order to ensure the best and most effective results from external wall insulation:

  • Initial inspection; this is essential in order to identify any problem areas before treatment to ensure the most effective treatment can be completed.
  • Pressure washing external walls to clean off any dirt and grime that has built up over the years. This will normally be followed by algae treatment on any areas that are affected by algae.
  • Cracks in masonry should be cleaned to remove loose material, and repaired with a suitable filler. Any areas of render that require repairing will also be attended to at this stage.
  • If necessary, poor quality stonework will be stabilised by adding a layer of fast drying adhesive bag coat.
  • Areas that are not to be treated will then be masked – this includes windows and door (including frames). The ground adjacent to the building should be covered with tarpaulin or dust sheets to protect from over-spraying.
  • A primer coat should then be applied to the surface. This is necessary to create a strong bond and ensure a long-lasting finish.
  • The spray coating can now be applied using industrial spraying equipment which will provide a fast application and also the highest standard of uniform finish.
  • The final stage should be a thorough clean-up of the site. This involves removing all masking and clearing all materials used in the installation from the property. At this point, the site will be ready for the owner to inspect – accompanied by the site foreman.
