🪟 EQUAL OR UNEQUAL SIGHTLINES? IT'S ALL ABOUT THE LOOK! 🏡

When choosing new windows for your home, even the smallest design details can make a big difference! Equal sightline windows create a balanced, symmetrical appearance, with frames and glass areas neatly aligned for a beautifully uniform finish. Unequal sightline windows feature different proportions between fixed and opening sections, often reflecting the original architectural character of your property. ✨

At SCI Windows, we believe the perfect replacement windows should combine style, energy efficiency and performance without compromising your home's character. Whether you prefer traditional symmetry or a more individual appearance, we'll help you find the perfect balance! 🏠

✅ Two different styles. One beautiful result.

A specialist rooftop installation completed near Putney Hill, London SW15. We replaced 12 plant room doors and bathroom windows using durable, low-maintenance Liniar PVCu, robust door hinges and practical tilt-and-turn mechanisms. The new units help conceal and protect water tanks, ventilation shafts, light wells and essential building services, while improving ventilation, weather resistance and safe maintenance access. A smart, long-term solution for this residential block management project in South West London.

Sliding sash windows are a clever way to naturally ventilate your home. Opened at the top and bottom, warm air rises and escapes through the upper gap, while cooler fresh air is drawn in below, creating a gentle convection current.

A simple, elegant way to keep your home feeling fresher and more comfortable.

Keeping the Edwardian features was the priority for this project. The customer wanted to replace all the front windows, so we installed FlushSash windows to the first floor and sliding sash windows to the ground-floor bay.

When installed sympathetically, PVCu offers a great alternative for customers looking for a low-maintenance solution without compromising the character of their home.🏠

The original timber porch had deteriorated over time, offering minimal security, poor insulation, and little protection from the elements 🏚️❄️. It was carefully removed, with the base expertly levelled and raised to accommodate a modern, fully insulated and weatherproof PVCu porch replacement—designed for long-term performance and comfort 🛠️🏡.

A single outward-opening door now creates a wider, more practical entrance 🚪, replacing the previous narrow double doors and improving everyday convenience 👍. The clean, chamfered PVCu frame and door design subtly replicate traditional timber styling, making it an ideal choice for homeowners seeking a sympathetic upgrade ✨.

Featuring energy-efficient double glazing 🌡️, excellent thermal insulation, and a modern high-security multi-point locking system 🔒, this new porch significantly reduces heat loss, enhances home security, and helps minimise external noise 🔇.

This low-maintenance PVCu porch installation delivers the perfect balance of heritage-inspired design and modern performance—ideal for improving kerb appeal 🌿, energy efficiency, and overall property value 📈.
