The Process of applying External Wall Insulation on your Park Home

The process of applying External Wall Insulation (EWI) to a Park Home involves several key steps.

An outline of our process is detailed below:

STAGE 1

Assessment and Preparation

Before beginning the External Wall Insulation installation, the Park Home’s exterior walls are assessed for their condition and suitability for insulation, eg. Does the property have an overhanging roofline? Any existing damage or areas of concern, such as cracks or dampness, may need to be addressed prior to installation. Any necessary repairs or surface treatments are carried out at this stage.

Insulation Material 

Our 6-layer Park Home External Wall Insulation system, features thick grey graphite expanded polystyrene boards, which you can select the thickness of, topped with layers of reinforced glass fibre mesh and render that sets rock hard.

STAGE 2

Installation of Insulation Panels

Insulation panels are then installed onto the exterior walls of the park home using mechanical fixings.

The panels are carefully positioned and secured to create a continuous layer of insulation across the entire wall surface, ensuring no gaps or voids are left behind.

STAGE 3

Reinforcement, Base Coat Application and Render

Once the insulation panels are in place, a reinforcing mesh is typically applied over the surface to strengthen the system and provide additional support.

A base coat of cementitious render is then applied over the mesh to fully encapsulate the insulation panels, making your Park Home waterproof, weatherproof and creating a smooth and even surface for the final finish.

Once this stage has been completed, you should start to feel the benefits of your External Wall Insulation.

STAGE 4

Topcoat Finish

The final stage involves applying a decorative render or painted Topcoat over the base coat. This coat is applied using a trowel, and the colour is already pigmented into the tubs.

Some painted Topcoats can dry and cure within 24-48 hrs, but they do need warm and dry weather conditions to dry and set effectively and to avoid the rain washing it off the walls. During the inclement weather, we do use a winter bond, which is only available in white, but that does set even in light rain! 

Once completed, the finished Topcoat enhances the aesthetics of the Park Home and provides a final barrier against weathering, moisture, and UV exposure.

STAGE 5

Quality Control and Inspection

Throughout the External Wall Insulation installation process, Platinum Park Home Services implement quality control measures to ensure that each step is carried out correctly and according to industry standards.

Once the installation is complete, a final inspection is typically conducted to verify the integrity and performance of the External Wall Insulation system and address any remaining issues or concerns.

Overall, the process of applying external wall insulation to a Park Home involves careful planning, preparation, and execution to achieve optimal thermal performance, durability, and aesthetics. Hiring a qualified and experienced company is recommended to ensure a successful External Wall Insulation installation that meets your specific needs and requirements.

At Platinum Park Home Services, we pride ourselves on minimal disruption during installation, typically completing an External Wall Insulation project in just 3 to 5 non-consecutive days – depending on the great British weather!

I have just had my external wall insulation completed and I couldn't be happier. The initial works completed by the lovely George of the external flue and tap extensions got things off to a good start. George was polite, respectful of my property and conscientious. A week later the main work started. Arturas, Rytis & Faustas worked so hard over 3 very full days and despite a couple of hitches, they made me aware of them even though they were able to resolve them. I hope the ice lollies provided helped in some way to keep them going. They cleared everything at the end of every work day and on completion of the work made sure I was 100% happy before they left. I really am very happy that I chose Platinum for this work.

On Thursday 9th July 2026 we had the most fantastic team of men came to do our loft and under floor insulation. The team consisted of Eve, Benas, Tomas and Antanas. I can honestly say that I have never seen anything like it. In record breaking temperatures these 4 men did not faulter. They worked so incredibly hard without complaint or moaning. They were polite, curtious and knowledgeable. The work was carried out to perfection. Photo's were taken of before and after and shown to us. We would 110% recommend Platinum Park Home Services to anyone considering having any renovation work done to their Park Home. Thank you Platinum Park Home Services especially, Eve, Benas, Tomas and Antanas.

Thanks to Ant and Ethan for sticking with what turned out to be a very tricky bathroom refurbishment. This is the second time I have used Platinum and have been very pleased both times.
