Why Replace Metal-Framed Windows?

Many historic properties still have original metal-framed or timber windows, which, while charming, often suffer from draughts, condensation, and poor thermal efficiency. Traditional steel or timber replacements can be expensive, prone to rust or rot, and require frequent maintenance.

Why Aluminium is the Perfect Alternative

Aluminium is a low-maintenance, cost-effective material that’s virtually indistinguishable from steel but free from issues like rust and corrosion. With the development of the innovative polyamide thermal break, aluminium windows are now among the most thermally efficient options available, combining modern performance with heritage aesthetics.

Designed for Heritage Renovations

Decorio’s external collection offers slim sightlines and traditional steel-like profiles, designed specifically for heritage renovations. Thanks to the development of the polyamide thermal break, these windows aren’t just stunning—they’re also highly thermally efficient, providing modern performance without compromising on aesthetics.

What makes our range truly stand out is its versatility. Whether you’re working on a Victorian terrace, an Art Deco masterpiece, or a quaint countryside cottage, our collection seamlessly blends into the existing architecture. Better still, our systems have been approved for use by local authorities across the UK, ensuring compliance with the stringent requirements of conservation areas.
