Alitherm Casement Windows
Unmatched Views with a 60mm SightlineImagine transforming your space with patio doors that disappear, maximizing your connection to the outdoors. Our innovative ultra-slim design boasts the slimmest sightlines on the market - a mere 60mm - creating a seamless transition between your home and the beauty outside.
IIMore Than Minimalist, More Than Functional
We've surpassed the limitations of both sliding and bifold doors. Our doors offer the sleek aesthetic of a sliding door with the added benefit of a fully unobstructed opening when fully deployed. Unlike bifolds, they allow for furniture placement on both sides, providing unmatched versatility. Plus, a built-in traffic door allows for everyday use without needing to move all panels.
Uncompromised Security and Weather Protection
Rest assured, your home is secure. These doors meet the latest PAS24 security standards when equipped with laminated safety glass. Advanced weatherproofing keeps your home warm and dry year-round. Thermally insulated frames and high-performance glass units contribute to energy efficiency, reducing your bills and meeting current building regulations.
Unparalleled Style and Customization
Experience flawless craftsmanship with a wide variety of colours (over 150!), designer handles, and a low-threshold option for seamless indoor-outdoor flow. Choose from clear safety glass with argon gas fill for optimal insulation, or upgrade to laminated glass for enhanced security.
Design Options for Every Vision
Our doors come in single, double, or multi-panel configurations (3-8 panels), with fixed or open corner options to suit your space. We even offer a steel-look version for an industrial aesthetic.
Direct from Design to Installation
Benefit from a single source for design, manufacturing, installation, and support. We guarantee a personalized service, professional installation, and a product built to last.
