The Best Exterior Wall Insulation Services in Hampshire

There are many questions that come to mind when people are considering external wall insulation in Hampshire. The main question is usually whether or not the insulation will actually make a difference in the home’s energy efficiency and where/when can you use it? To help local customers with this, we have compiled a list of common questions and answers 

So what is exterior wall insulation?

External wall insulation can typically be described as a layer of insulation permanently fixed to an existing wall. This layer will be finished with cladding to protect it from external elements.

This method is often required for properties with solid walls with no insulation options, such as cavity wall insulation.

What is the cost of external wall insulation?

A three-bedroom semi is likely to cost on average £6,000-9,000, with a larger detached home in the region of £8,000-£16,000. This cost includes aspects like scaffolding, re rendering and making good any issues. A full survey must be conducted on your property in order for an accurate quotation and completion timescales to be provided. 

Will I need planning?

In most cases external wall insulation will change the appearance for the externally facing parts of a property. For this reasons it is prudent to check if planning permission is required. For heritage buildings, it may be challenging to secure planning permission, so it is always advisable to do ‘pre checks’ with the local authority.

Building regulations and external wall insulation

If 25% or more of your external wall is being updated with insulation, then building regulations suggest that the remaining parts of the wall must be bought up to current standards. This makes sense, if you’re going to go to the expense of external wall insulation, then you should do it properly.

Can I use external wall insulation on a solid stone wall?

‘Solid’ stoned walls tend to have a cavity filled with rubble, bungaroosh or brick. The natural dew point (the point at which the air temperature is cooled to where it can become saturated as water vapour) will be between that ‘space’ plus the external surface, so potential moisture can either fall out of the wall to the ground or evaporate away. Internal insulation has no significant impact on this factor, and the dew point will move further outwards, so any internal moisture penetrating the wall will still be dealt with in the division.

Stone walls tend to be breathing walls, so maintaining this breathability ensures that the division continues to operate as designed.

In this case, using breathable insulation, for example, cork, wood fibre or similar – with a lime external render to complete the finish.

Perhaps an ideal solution would be a 90mm layer of wood fibreboard like Pavatex, Diffutherm, or similar – fixed to the wall via mechanical means.

These materials are readily accepted render. A 20mm hemp-lime render would be applied in two 10mm coats and can be coloured to suit or painted with a lime wash.

As an alternative option to this, you could consider a 70mm rigid foam insulation like Celotex or Kingspan that is mechanically fixed to the wall and then clad with a render of sand or cement, timber cladding or a weatherproof layer.

What about solid brick walls?

Unlike stone, adding external insulation to a brick wall will have little impact on its performance. In this case, it’s best if you use any of the rigid form insulations that are designed for walls like these because they work well in tandem with bricks and mortar without compromising airflow or breathability as much compared to other materials.

Insulation’s thermal performance is critical to consider when designing a home. Insulation can absorb or reflect heat depending on its material and thickness; this affects both heating bills and what kind of comfort level one has at their house and outside walls during winter months because less warmth makes for colder rooms with lower temperatures. So as you can see, adding high-performance insulation can be a big help, and different insulation systems used on your outside walls can improve the thermal performance of your home depending on the type of insulation used.

We can provide you with a variety of external house insulation using Kingspan kooltherm ks to provide outside warranties that will keep your home warm in winter and cool during summer.
Kiln dried render, plastic cladding or even ceiling panels are just some options for those who want their houses look stylish as well. Kingspan's new Kooltherm k5 is an excellent choice for exterior insulation. The combination of Kingspan insulated render with ewi makes it easy to insulate your walls without any hassle or trouble, while still achieving superior quality in both materials absorption rates
