Description
Renolit, a leading global manufacturer of high-quality plastic films and laminates, has long been synonymous with innovation in surface solutions for the building industry. Among its range of professional ancillary products, the Renolit Profi Corner Pens (also known as RENOLIT EXOFOL Professional Corner Pens) stand out as an essential tool for installers, fabricators, and window/door specialists. These precision-matched pens are specifically designed to enhance the aesthetic quality of profiles laminated with RENOLIT EXOFOL decorative films, delivering seamless, professional-grade results that elevate the final appearance of modern windows, doors, and façade elements.
At the heart of the Renolit Profi Corner Pen’s appeal is its ability to achieve absolute colour reproduction and seamless joints. When fabricating window and door frames, mitre cuts at the corners are welded together to create strong, durable joints. However, even the most precise welding can leave subtle visible lines or slight colour mismatches due to heat effects, material flow, or minor imperfections. This is where the Profi Corner Pen excels — it acts as a targeted touch-up solution that makes these joints virtually disappear.
The pens are engineered to match the exact shades and patterns of RENOLIT EXOFOL foils, which include an extensive portfolio of solid colours, metallic effects, woodgrain decors, and textured designs.
This vast colour matching ensures that, regardless of whether the project calls for contemporary matt greys, classic wood-look decors, or modern metallic accents, there is a corresponding Profi Corner Pen available. Each pen is formulated to replicate not just the base colour but also the undertones, grain structure, and surface sheen of the specific EXOFOL laminate.
Functionally, the Profi Corner Pen operates much like a high-end felt-tip marker, making it intuitive and user-friendly even for professionals working on-site or in busy fabrication workshops. The ink flows smoothly for controlled application, allowing precise detailing along mitre joints, edges, or small surface blemishes. For added convenience and longevity, every pen includes a replaceable spare tip that can be swapped out by hand when the original wears down. This feature extends the pen’s usable life significantly and maintains consistent, clean application throughout multiple projects.
The result? Immaculate application and perfect results every time. Installers report that using these pens transforms good work into outstanding work — corners that once required careful scrutiny now blend effortlessly into the overall profile, giving the impression of a single, continuous surface rather than assembled parts. This level of finish is particularly valuable in premium residential projects, commercial builds, and architectural applications where aesthetics are paramount.
In an industry where attention to detail defines quality, the Renolit Profi Corner Pens represent a small but powerful investment in excellence. They save time on post-processing, reduce the need for rework, and help deliver the flawless, high-end appearance that clients expect from modern PVC-U, aluminium, or hybrid window and door systems. Whether you’re matching a rustic oak grain on a countryside property or a sleek matt black for an urban minimalist design, these professional-grade pens help achieve that seamless, factory-fresh perfection — proving once again why RENOLIT remains a trusted name in exterior surface solutions.
