Why Install External Wall Insulation in Lincolnshire?

If you are based in the North-East Lincolnshire area, such as Grimsby, then External wall insulation is really great for protecting against the coastal weather conditions that your home will be susceptible to.

Coastal areas are more prone to extremes of weather, even if you don’t live directly next to the sea you can experience harsh winds, rain, sea salt spray and potentially colder temperatures. All of these things can be damaging to the exterior of your property, and if your home isn’t insulated well enough it can be drafty, cold and damp. When installed correctly by an installer such as RamEco, EWI can make a huge difference to how your property copes with extreme weather conditions. 

External wall insulation can offer you and your home with many benefits.

What are the Benefits of External Wall Insulation?

  • Sound-proof and improve the acoustics of the property
  • Improve the aesthetics of your property
  • Your home will be warmer in the winter and cooler in the summer
  • EWI takes up no internal floor space
  • Protect against harsh climates (e.g. coastal homes)
  • Prevent damp and condensation (e.g. humid conditions in coast areas)
  • Reduce energy consumption and therefore save you money in the long term.
  • Increase the lifespan of the property.

We recommend our silicone render system for coastal areas, because it is hydrophobic and therefore moisture repelling. This means that your EWI system and you home will be protected against problems of damp that can be caused by the humidity and harsh weathers.

What is Acrylic Render?

About Acrylic render

What is acrylic render? We often get asked this, because there seems to be a fair amount of confusion as to what the difference is between acrylic and silicone renders or acrylic and Monocouche Scratch Render. So, we’re going to break it down into what acrylic render is, what its properties are and how it compares to the other renders that we offer.

Acrylic render is a wet, thin-coat render which comes pre-mixed (ready to use) in a wide variety of colours, used as a decorative finish to an EWI system. Our EWI-010 Acrylic Render comes in four different grain sizes: 1.0mm, 1.5mm, 2.0mm and 3.0mm. What this means is that when you look at the wall from a distance, the larger the grain size the more apparent the texture will be, it’s all down to personal preference but essentially if you want a smoother surface you’d go for a 1.0mm grain size.

Acrylic render is a popular choice because it’s long-lasting, aesthetically pleasing and forms a strong protective barrier over your EWI system or simply as part of a render-only system.

Why is Acrylic a popular render?

If you wish to paint your house a bright colour and you are looking for a coloured render that can be mixed into any shade, then through-coloured acrylic render is great because much like acrylic paint it bonds to colour pigment well, so the intensity of the colour will last much longer than other coloured renders. This means that you won’t need to re-paint it every 10 years or so, which can be consuming on your time and money, and considering that our acrylic render is one of our cheapest, it’s a pretty cost-efficient way to render your home.

Acrylic render is also a great choice in terms of being crack resistant, so it will ensure longevity in this respect. Our acrylic render is also the best value in comparison to other coloured renders, because it is long-lasting and only needs to be applied in one coat, so you will save money on labour costs.

Acrylic render and Silicone render

However, there are some minor downsides to the acrylic render when you compare it to the silicone render. Acrylic takes slightly longer to dry, so cannot be installed in wet conditions – but this is common for renders anyway. It’s also a little bit less resistant to extreme weather conditions and due to the fact that it doesn’t contain silicone it doesn’t have the same hydrophobic properties as silicone render.

Silicone render also has self-cleaning properties, which means it is less prone to organic growth. So in terms of comparing it to acrylic render, you’ll probably need to clean acrylic more regularly than Silicone.  Acrylic render does offer breathability, however it isn’t quite at the level that silicone render can provide.

Acrylic render and Monocouche Scratch render

Whilst silicone render could be considered the slightly higher performing sibling to acrylic, monocouche is very different. The monocouche render is a thick-coat, traditional-style render. Instead of coming readily prepared, it needs mixing with water in a mechanical mixer and then it is applied to the wall in two layers with a trowel. Once both the layers have set slightly, it is scratched back to create the desired texture.

The good thing about the monocouche render is that once you have gone through the application process, it is pretty much maintenance free and, as with all of our renders, is very long lasting.

So, there you have it, acrylic render is a great thin-coat render that can offer you the good performance and longevity that you require! If you are interested in any of our renders and you are still feeling unsure about which direction to go in, then do give us a call as our sales team are all experts and would be happy to help.

Can I install EWI onto my flat?

There seems to be a bit of a gap in information out there about whether it is possible to install external wall insulation (EWI) onto a flat, so we wanted to answer this question for you and provide as much information as possible for any flat-owners who are considering EWI!

In most cases the answer is yes, you can install EWI onto a flat. However, usually the insulated render system is sealed at the top where it meets the soffit of the roof. So, on a groundfloor flat the insulation must be sealed at the top by other methods. This is because if it isn’t sealed, the exposed edges of the insulation can allow for water to seep behind the back of the insulation boards which can in turn effect the integrity of the EWI system, and water can then also enter the property through the walls causing problems with damp and mould.

We would recommend that EWI is most ideal for people who own a ground floor flat. This way, the EWI is at least sealed at the base so to prevent too much heat loss and water ingress, and the EWI will most likely be less noticeable.

So how do you install external wall insulation onto a flat?

Installing external wall insulation onto a flat is a slightly different process than with a normal house. This is because if the top of the insulation is exposed, i.e. does not meet the soffit of the roof, then certain actions will have to be taken to ensure that the EWI on your flat is water-tight.

There are a few options to consider in order to achieve a water-tight finish:

With the upper ledge of your insulated render system exposed, you will always need to use a verge trim to protect the EWI from water exposure. One option is using a basic verge trim which screws into the wall above the EWI. However, this is not entirely water tight because the top of the verge trim is not sealed, so you will need to use a sealant along the upper edge of the external insulation to prevent water running down its back.

The second option is using a Grind-in verge trim. As the name suggests, this is a verge trim with the length of its upper edge inserted into the wall surface. However, you have to first damage the surface of the existing wall to insert the verge trim, and the result is that it’s still not completely watertight. This method is therefore still a bit risky.

We suggest that the best option is to use lead flashing with a normal verge trim. This doubles up the waterproofing so that the lead flashing protects the verge trim, and the verge trim protects the top of the EWI.

As for the base of the external solid wall insulation, if it’s exposed (because your flat is not on the ground floor), then we recommend the use of white PVC so that it will look nicer for your neighbours below to look up at.

Pro’s of installing external wall insulation onto your flat

EWI is a great way to save energy on your heating bills. Most flats have electric heating, which is far more expensive than gas heating. This means that heat loss through the external walls of a flat is much more problematic for you as the homeowner, because you then need to spend even more money on re-heating the flat. EWI can dramatically reduce the amount of heat being transferred through the walls of your flat and save you a lot of money on energy bills every year.

As well as this, people who live in flats are often in a more built up area which suggests more noise from road traffic. For people living on ground-floor flats this is potentially more of an issue and can be exceedingly unpleasant, so installing insulated render can greatly improve the amount of noise that enters your home.

People living in flats are also the most likely candidates to be struggling for space. EWI takes up absolutely none of the internal floor space, which means that your property will not lose any value due to a decrease in the size of its rooms and you will still have plenty of moving around space!

Cons of installing EWI onto your flat

If you install external wall insulation onto your flat, depending upon the thickness of the insulation boards, it could mean that the external walls of your flat will physically stand out from the rest of the building and the necessary verge trim may not be a particularly attractive feature to look at. Also, depending upon the external walls of the rest of your building, you might need to spend more to ensure that your render matches the overall look of the building. There are a number of ways you can do this, for example we offer a variety of very realistic looking brick slips which could work really well at blending the EWI on your flat in.

Most flats are lease-hold only, so you would likely need to ask for permission to install EWI, which is potentially a long and difficult process. It can be an expensive job for a small property and is not guaranteed to be as energy efficient as if you were to insulate an entire house, for example. Also, you will have increased scaffolding costs if your flat is on an upper level.

People who live flats live in very close quarters with their neighbours, so any work being done to your flat is likely to be more disruptive. Upset neighbours may therefore complain about any disruption during installation time, and may not be all too pleased with the finished look.

The best thing to do when considering an EWI installation is to seek professional advice. We recommend that you hire a surveyor to discuss the feasibility of installing EWI onto your flat. Our staff are all extremely knowledgeable about EWI, and are always happy to help in any way. For any enquiries, please do not hesitate to call us here at EWI Store.
