External Cladding Trim

External Cladding Trim is a vital element of a building’s exterior by contributing to both its visual appeal and durability. By covering and safeguarding the edges of cladding panels, it ensures a clean and seamless finish, while simultaneously protecting the panels from potential damage.

Our External Cladding Trim is designed with the highest quality standards in mind. This is to provide a low-maintenance and weather-resistant solution for many architectural styles. Our selection caters to the preferences of homeowners and builders alike, offering a diverse range of colours and design. From bold, modern to classic designs, there is a cladding trim option for everyone. By choosing our high-quality External Cladding Trim, you can create a harmonious and visually appealing exterior.

Fascia Board Corner

Fascia Board Corners play a vital role in preserving a tidy and polished appearance at the edges of rooflines. These components connect and conceal the ends of fascia boards, guaranteeing a flawless and continuous look. In addition to their aesthetic function, Fascia Board Corners serve as a protective measure against water penetration, safeguarding the roof structure from potential damage.

Our Fascia Board Corners are crafted from high-quality uPVC, offering an array of benefits such as low maintenance, weather resistance, and long-lasting durability. We provide a diverse selection of colours and styles to suit various design preferences. Whether you prefer a bold, contemporary look or a more traditional, classic appeal, our range of Fascia Board Corners can be tailored to match the colour and style of your existing fascia boards.

Fascia Board Joints

Fascia Board Joints are responsible for linking separate segments of fascia boards to provide an orderly and continuous finish. These joints are essential in accommodating the expansion and contraction that occurs due to temperature changes, preventing the fascia boards from warping or splitting.

Our high-quality uPVC Fascia Board Joints offer numerous benefits, including low maintenance requirements, resistance to weather, and lasting durability. This material selection ensures that the joints maintain their functionality and visual appeal over time.

We offer an array of styles and colours for our Fascia Board Joints, designed to blend effortlessly with your current fascia boards. This design consideration results in a unified and refined appearance for your property’s roofline.
