About
SEF Ltd specialises in providing premium insulation and rendering solutions designed to enhance energy efficiency, comfort, and aesthetic appeal in both residential and commercial properties. Our expertise covers a comprehensive range of services, including Spray Foam Insulation, Thermal Foil Insulation, External Wall Insulation (EWI), Internal Wall Insulation (IWI), and high-quality Rendering finishes.
Our spray foam loft insulation services offer a seamless and effective solution for insulating attic spaces. Using advanced equipment and premium-grade materials, our team ensures precise application, resulting in superior thermal resistance, excellent air sealing properties, and enhanced moisture control. Whether retrofitting an existing property or insulating a new build, spray foam insulation offers substantial energy savings and year-round indoor comfort.
We also specialise in installing SF19+ thermal foil insulation under loft rafters. This innovative multi-layered product combines reflective foil, bubble wrap, and foam to create an efficient barrier against heat transfer. By reflecting radiant heat and minimising thermal bridging, SF19+ insulation helps maintain consistent indoor temperatures and reduces energy consumption. Its lightweight and flexible design makes it ideal for loft applications, providing long-lasting and effective performance.
Expanding beyond loft insulation, SEF Ltd provides professional External Wall Insulation (EWI) systems that significantly improve a building’s thermal efficiency while also enhancing its exterior appearance. EWI is perfect for reducing heat loss through walls and lowering heating costs, especially in older or poorly insulated buildings.
Our Internal Wall Insulation (IWI) services are ideal for properties where external insulation is not feasible. IWI enhances thermal performance from within, offering a discreet yet powerful solution to improve comfort without altering the building’s exterior.
To complete our full-service offering, SEF Ltd delivers expert rendering solutions that not only protect your property but also give it a clean, modern, and attractive finish. We use durable, weather-resistant materials to ensure your home or commercial building looks great and performs well in all seasons.
At SEF Ltd, we are committed to delivering top-quality insulation and rendering solutions that exceed expectations. With a skilled team of professionals, a customer-first approach, and a dedication to sustainability, we help clients create warmer, more energy-efficient, and visually appealing spaces.
Choose SEF Ltd for all your insulation and rendering needs—experience the difference in performance, energy savings, and comfort.
