SATE (external thermal insulation) means bonding insulating panels to the facade and protecting them with a layer of render and finish. Insulating from the outside removes the thermal bridge, so the building stops losing heat in winter and overheating in summer.
In the Costa Blanca climate the biggest cost is usually air conditioning. A well-insulated facade keeps the home cool for longer and cuts the hours the unit runs, saving on the electricity bill and giving a far steadier indoor temperature.
Beyond the savings, SATE completely renews the look of the facade and improves the energy rating — increasingly valued when selling or letting. Spain offers energy-renovation grants, including Next Generation funds; we explain the requirements and, for overseas owners, coordinate the paperwork remotely.
SATE Facade Insulation in Alicante: what's included
External thermal insulation
We bond insulating panels across the whole facade to wrap the building without losing interior space.
Removal of thermal bridges
We treat edges, reveals and slab fronts where heat escapes and condensation forms.
Better energy rating
We cut the heating and cooling demand and help raise the letter on your energy certificate.
Facade finish and protection
We apply mesh, render and a final coating that renews and protects the wall.
Guidance on grants
We explain the energy-renovation subsidies and prepare the technical note and quote.
Coordination with windows and AC
We coordinate with window replacement and air conditioning to maximise the combined saving.
The full scope of SATE Facade Insulation works
Every job we take on within this service, with the detail of how we carry it out. The price is always fixed after the survey.
Survey and choosing the system
Surveying the existing facade
- What we do
- We check whether the facade as it stands will take the SATE system.
- How we do it
- We run a pull-off adhesion test and open up sample patches of the existing finish. A hollow monocouche render or a plastic paint with no grip has to come off first: the system has weight, and it hangs on whatever is underneath it.
Choosing the insulation
- What we do
- We define which material and thickness your facade actually needs.
- How we do it
- On the coast we usually propose graphite EPS for performance against cost, mineral wool where fire-reaction rules at height, and XPS at the plinth for its water resistance. The choice is justified in the quote, not imposed.
Calculating the thickness
- What we do
- Working out how many centimetres of insulation genuinely pay their way.
- How we do it
- We calculate for the climate zone the Spanish CTE code applies here and the orientation of each elevation. Past a certain thickness the gain flattens out: going thicker adds cost without returning it in comfort or on the bill.
Thermal survey beforehand
- What we do
- Seeing where the heat actually escapes before we design.
- How we do it
- The thermal camera reveals the slab fronts, columns and shutter boxes acting as bridges. Without that map you insulate the flat wall and leave untouched exactly the points causing the condensation inside.
Energy certificate before and after
- What we do
- Documenting the real improvement in the property’s rating.
- How we do it
- We process the certificate before and after, which is what evidences the jump in rating to the grant body and to a future buyer or tenant. Without the "before", many grant rounds will not accept the application at all.
Installing the system
Scaffolding
- What we do
- Access equipment and protection for the duration of the work.
- How we do it
- We erect certified scaffold with netting and edge protection, and apply for the street occupation licence where the facade fronts the road. On the front line we check the ties more often because of the easterly winds.
Preparation and levelling
- What we do
- Leaving the substrate clean, sound and true.
- How we do it
- We strip whatever is not holding, make good and level out any lean with mortar. A substrate more than a centimetre out passes that irregularity straight through to the final finish — and it shows in the raking afternoon light.
Bonding and mechanical fixing
- What we do
- Fitting the insulation boards across the whole facade.
- How we do it
- We bond with adhesive mortar in a perimeter bead and dabs, in stretcher bond with interlocked corners, then add fixing pins once it has set. It is the mechanical fixing that resists wind suction at height.
Base coat and reinforcing mesh
- What we do
- Reinforcing the system over the fitted insulation.
- How we do it
- We apply base coat and bed glass-fibre mesh into its outer third, lapped between sheets with diagonal reinforcement at window corners. That is exactly where the system cracks if it is not reinforced.
Plinth and base detail
- What we do
- Resolving where the system meets the ground.
- How we do it
- We start on a base rail with water-resistant insulation at the plinth, held clear of the ground. A SATE that simply dies into the ground wicks water at the base and eventually debonds from the bottom up.
Thermal bridges and tricky details
Slab fronts and columns
- What we do
- Treating the cold lines that run across the facade.
- How we do it
- We wrap the slab edge and the column in the same continuous layer of insulation. This is the whole point of external insulation: insulate internally and these points stay unresolved and go on condensing in the corners of the living room.
Window reveals and heads
- What we do
- Insulating around the openings.
- How we do it
- We line the reveal, head and sill with a thinner board and a drip bead. Without that return, the opening becomes the cold spot that concentrates mould in the corner of the window.
Shutter boxes
- What we do
- The coldest, leakiest point on almost every facade.
- How we do it
- We insulate the box externally and seal where the strap passes through. In many 1980s properties the shutter box is a direct hole to the outside, and you see it in the air-conditioning bill.
Terraces, balconies and railings
- What we do
- Carrying the insulation through the projecting parts of the facade.
- How we do it
- We resolve the balcony edge junction and refit the railing anchors with a thermal break. This is the detail that demands the most precision: any shortcut here comes back as a crack or as water ingress.
Downpipes, units and cabling
- What we do
- Relocating everything currently hanging on the facade.
- How we do it
- We take down and refit downpipes, AC condensers, lights and cabling on the new face, with fixings passing through to the original structure. An anchor that stops in the insulation alone ends up on the ground.
Finish, grants and the community
Final render coat
- What we do
- The layer that gives the appearance and protects the system.
- How we do it
- We apply primer and an acrylic or siloxane topcoat depending on exposure: on coastal facades siloxane copes far better with salt and humidity. We pick colour and grain with you from a sample on site, not from a catalogue.
Colour and reflectance
- What we do
- Choosing a colour with the heat in mind as well as the look.
- How we do it
- We recommend medium to high reflectance on south and west elevations. A dark shade over SATE stores heat, expands the render and works against the very thing you installed it to fix.
Grant applications
- What we do
- The technical paperwork for energy-renovation subsidies.
- How we do it
- We prepare the technical note, itemised quote and before/after certificates, including what the Next Generation funds require. We tell you in advance whether your scheme reaches the demand reduction the round demands. For overseas owners we run this by email.
SATE for an owners’ association
- What we do
- The system applied to a whole residential block.
- How we do it
- We support the proposal at the AGM with the documentation needed and phase the scaffold elevation by elevation to limit disruption. This is where the system pays best, because the scaffold cost is shared by everyone.
Coordinating with windows and AC
- What we do
- Fitting SATE around new joinery and air conditioning.
- How we do it
- If you are replacing windows, do it first or at the same time: the SATE finishes onto the new frame, so nothing is touched twice. With the facade insulated, the air conditioning can also be sized to a lower output.

SATE Facade Insulation: frequently asked questions in Alicante
How much does it cost to insulate a facade with SATE?
It depends on the facade area, the thickness and type of insulation, the condition of the wall and whether scaffolding is needed. Every building is different, so we fix the price after the visit. Grants can also reduce the outlay. Request a free, no-obligation personalised quote.
How much will SATE save on my bills?
The saving depends on the previous state of the facade, the orientation and your habits, but removing thermal bridges markedly cuts air-conditioning and heating use. Comfort improves straight away: less heat in summer and less cold in winter.
Are there grants for facade insulation?
Yes. Spain has home energy-renovation grants, including Next Generation funds, which can cover a significant share of the work. We explain the requirements and prepare the technical documentation, and can handle it remotely for overseas owners. Award and amount depend on each call.
Does SATE reduce the interior space of the home?
No. Insulating from the outside loses no space at all inside, unlike internal insulation. The thickness is added over the existing facade, which is why it is the preferred option when you want to keep every bit of usable floor area.
Can it be installed on an apartment block?
Yes, and that is where it performs best, because the saving and the improved appearance are shared across the whole community. We coordinate with the owners’ association, schedule the scaffolding and can process the work alongside any available grants.
