Air conditioner- or external wall insulation ?

28 06/17

If you’d like to make your home cooler, but don’t need something as powerful as an air conditioning unit, it’s worth considering external wall insulation.

You may have noticed that your neighbour is having external solid wall insulation installed on their property. Summer is the perfect time for you to do the same!

External wall insulation is a great way of lowering your energy bills and giving your home a facelift at the same time. It is an easy way to dramatically lower the temperature of your home on hot summer days.

Summer is the best time to install external wall insulation!

At BeConstructive, we have installed 1000s of properties with solid wall insulation over the years, and all our systems come with a 25 year manufacturer-backed warranty.

Our system involves adding 100mm or 90 mm of external wall insulation to the wall with a combination of adhesive and mechanical fixings. This not only ensures a really secure finish that will withstand the elements, but also looks great and will save you huge amounts on your energy bills.

What are acrylic brick slips?


When in restaurants, cafes and shops, you may have noticed beautiful brick feature walls – these are growing increasingly popular.
To create this brick effect look, a technique known as brick slip wall cladding is often used.


Using a special brick slip tile adhesive, the brick slips- or brick faces – are layered on the wall or floor in a pattern by our brick slips installers.
These brick style tiles can be used to give a brick effect on both internal and external walls, transforming the appearance and ambience of any property.

Be Constructive now offering the best alternative to dash render

Whether you have dry or wet dash on your wall, we have a better, cheaper and more visually impressive render for you!

For many years, we have only offered 2 main options in our popular thin coat render – a 1mm or 1.5mm top coat. We are now able to offer 2mm and even 3mm render. What is so great about 3mm silicone render? It looks just like wet dash, only better!

Why use silicone render over wet dash?

Silicone render is highly flexible, easy to apply, and lasts 30 years or more. It is a great alternative to dash because it is just as resilient, but allows your walls to breathe and provides a more aesthetically pleasing finish.

How annoying is it to have those pebbles randomly dropping off your wall months and years after the work has been done? With dry dash it is unavoidable; there are always going to be some pebbles coming loose with time. It can leave nasty scars on the wall as well. With silicone render this is just not an issue as the stones are deeply embedded in the render itself and will not come loose.

How does 3mm silicone render look?

Just like smaller grained render, the 3mm silicone has an even texture. Where wet dash can look blotchy and lumpy, silicone can still provide that rough textured look whilst maintaining an even and classy looking finish.

Because silicone render is premixed at the factory, you can be sure of a great mix time and time again. Dash is mixed up on site with a range of products not necessarily designed to work together. It’s not hard to see why a thin coat render is going to give you a better finish.


Because silicone render is premixed with the pigment, the render is the same colour all the way through. Dash is usually painted once the top coat has set, and this means that any scratches or damage to that paint will leave very obvious marks in the render. Silicone render has that same colour all the way through, so scratches are going to be much less visible.

Silcione render is cheaper!

Dash work is very time consuming, and all that extra work mixing the render on site really adds to the time involved. Plus you need to wait for the top coat to dry before it can be painted. That’s means several days where no work can be done – extending the job and adding to cost.

We guarantee to give you a better price on a silicone render job than with dash. It will always be cheaper for you.

External wall insulation and Dealing with boiler flues

Dealing with boiler flues

 Dealing with boiler flues


Boiler flues can be seen on most properties that are on the gas grid. You might see them protruding from the wall, sticking out of the roof, or stuck in an outbuilding. When it comes to EWI, boiler flues can be a real stumbling block. In this blog we are going to look at some of the common problems and how we deal with flues.


What is the problem with flues?

Most boiler flues that protrude from a wall only do so just enough to ensure that the flue is not obstructed. After all, no one wants a long plastic pipe sticking out from the wall. External Wall Insulation (EWI) can add a layer 100mm or more to the outside of the house, and this has obvious implications for the ability of the flue to function. If the flue is even slightly buried in the wall, it can stop the boiler from functioning properly, and could in the worst case scenario cause carbon monoxide building up in the home.

Obstructing the flue is therefore not an option, and a suitable solution must be found.

Why do I need to move my boiler flue?



Boxing around the flue

One cheap and easy way to finish around the flue is to not touch the flue itself, but to leave a space of 30cm or more from the flue to the insulation. This creates a recess, as shown in the photo, which is a big enough gap to ensure the flue can operate safely, whilst still insulating the vast majority of the wall.

It is also possible to bevel the insulation slightly to create a graded and more subtle dishing effect around the flue. This technique is often used where the cost of extending the flue is considered too high or prohibitive, or where it is not possible to extend the flue (due to an obsolete part for example).

Extending the flue

The alternative to boxing around the flue is to extend the flue so that it is level with the new wall depth. A gas safe plumber will be required to extend the flue using the appropriate manufacturers flue extension kit. The process is relatively simple and usually adds around £150-200 to the average job.

This is preferable to boxing around the flue because it looks neater, leaves a smooth and clean finish, and will not create a surface for dirt and grime to collect.

Mineral Wool a must around the flue

One more important thing to remember with flue extensions is to ensure you have some Rockwool or Mineral Wool around the flue when it is extended. Of course, if you are using this product for the insulation on the house anyway, then this goes without saying, but if you are planning to use EPS insulation then you must be very careful with the insulation used around the flue. The flue can get hot and potentially melt the EPS on the wall, whereas Rockwool has a much higher melting point and is therefore more suitable for use around the flue.

The flue is a important when doing external insulation, so make sure you are dealing with it in the best way possible. If in doubt, speak to the experts at Be Constructive!
