Thermal Property Upgrade in Weymouth
A Complete Exterior Transformation by Veramut Ltd
Located on a hillside in coastal Weymouth, this detached home had long battled the environmental pressures common to marine-front properties: high humidity, salt-laden winds, and seasonal temperature fluctuations. Its previous plastic cladding offered little resistance to these elements and performed poorly in terms of insulation, leading to higher energy bills and frequent maintenance demands.
The homeowners approached Veramut Ltd with a clear objective: thermal property upgrade with an aesthetically modern finish in mind.
1. Thermal Property Upgrade in Weymouth - Project Overview.
Location: Weymouth, Dorset
Colours:Spray Cork Render in Arctic White; Silicone Spray Paint for the roof in Anthracite
Duration: 3 weeks
Client goals: thermal property upgrade
2. The Challenge.
Coastal homes are exposed to various environmental stressors. In this case, the property was clad in dated plastic panelling. While initially cost-effective, plastic cladding presents several long-term challenges:
Poor thermal insulation, leading to heat loss in winter and overheating in summer.
Susceptibility to UV damage and salt corrosion.
Aesthetic degradation over time, including warping and discolouration.
Moreover, the property’s roof had become weather-worn. Discolouration, accumulation of moss, and cracked tiles compromised its function and appearance. These issues led to heat escaping not only through the walls, but also through the roof, a critical contributor to overall energy inefficiency.
The homeowners wanted more than just a cosmetic fix; they sought a genuine thermal property renovation to reduce energy usage, minimise ongoing maintenance, and enhance the value of their investment.
3. The Solution.
After assessing the issues and the overall condition of the existing exterior and roof, we proposed a modern and sustainable strategy that aligned with the homeowners' goals and the climate challenges of coastal Dorset. The chosen materials offered transformative benefits:
Spray Cork Render - The Thermal House Upgrade Essential for the Walls
Spray cork is a revolutionary material made from natural cork granules blended with resins and natural additives. It adheres to virtually any surface and forms a flexible, breathable membrane that improves thermal insulation (retains warmth in winter and repels heat in summer).
It is naturally resistant to salt, algae, UV rays, and cracking. It is also worth mentioning that spray cork render acts as an acoustic insulator, reducing exterior noise. This sustainable and eco-friendly product reduces environmental impact and comes in a range of colours (in this case, Arctic White was selected for a clean, modern finish).
Roof Renovation with Silicone Spray Paint
To complement the upgraded façade, we renovated the roof using silicone-based spray paint in Anthracite, a stylish and resilient solution.
The owners opted for silicone coating for a few reasons:
UV and water resistance, ideal for coastal and rainy climates.
Elasticity that bridges hairline cracks and prevents future tile damage.
Uniform, clean look that revitalises aged roofing materials.
Together, these choices delivered a complete thermal property upgrade, improved curb appeal, and long-term cost efficiency.
4. The Renovation Process.
4.1. Site Assessment and Material Planning.
Before initiating work, Veramut carried out a detailed assessment of the property, examining structural integrity, insulation deficits, and surface condition. A thermal imaging scan helped pinpoint where most heat loss occurred, confirming the need for both wall and roof treatment.
4.2. Cladding Removal and Wall Preparation.
The outdated plastic cladding was carefully removed to reveal the original structure. This step exposed minor imperfections and thermal bridging points, which were corrected using a base coat. The base coat served to even out the substrate and provide a firm bonding surface for the cork material. Once set, a primer was applied to ensure the cork’s adhesion and effectiveness.
4.3. Application of Spray Cork Rendering.
The walls were coated with two layers of spray cork, applied with specialised equipment for uniform coverage and texture. Arctic White was chosen to enhance natural light reflection and offer a clean contrast with the roof and landscaping.
Note: The number of spray cork layers applied always depends on the expected thermal effect. For properties requiring enhanced insulation or exposed to severe climates, additional layers may be advised to optimise performance.
As the cork dried, it formed a seamless, weather-resistant barrier that significantly improved the property's thermal envelope. The result was a breathable yet airtight finish that offered exceptional energy performance.
4.4. Roof Restoration.
After years of exposure to harsh coastal weather, the roof required a comprehensive restoration to bring it back to optimal condition. The process began with an intensive cleaning phase. Using industrial-grade pressure washers, the team carefully removed years of accumulated moss, algae, dirt, and salt deposits. This step was crucial not just for appearance, but to ensure proper adhesion of the subsequent coatings and to reveal any underlying structural issues that might otherwise go unnoticed.
Once we cleaned the roof, we conducted a detailed inspection to identify damaged tiles. As a result, we found several split and worn tiles across various sections of the roof. We carefully removed these and replaced them with high-quality matching tiles to restore the roof’s continuity and ensure its watertight integrity.
With the surface prepped and stabilised, we applied a primer across the entire roof. After allowing the primer to cure properly, we applied two even coats of silicone-based spray paint in Anthracite.The choice of Anthracite was intentional; not only does it add a sleek, modern finish that complements the Arctic White cork-rendered walls, but it also helps reduce glare and maintains its depth of colour under sunlight.
The silicone coating itself brought a host of performance benefits. Known for its good elasticity, it effectively bridged over fine hairline cracks and created a continuous, weatherproof barrier. Its high resistance to UV rays and water penetration makes it an ideal solution for coastal environments where roof surfaces are constantly subjected to fluctuating temperatures, sea spray, and wind-blown salt particle.

5. Summary.
This thermal property upgrade project in Weymouth proves our commitment to innovation, sustainability, and customer-focused solutions. By combining modern materials with skilled workmanship, our team delivered an impressive transformation that ticked every box: energy efficiency, visual appeal, and weather resilience.
The home, once outdated and inefficient, has been transformed into a stylish, energy-conscious solution ideally suited to its coastal environment.
