Available in a comprehensive range of styles including casement, tilt-and-turn, and heritage designs, all with 10-year guarantees. The windows meet the highest security standards with multi-point locking systems and reinforced frames.
Conservatory Roofs
Liniar's conservatory roof solutions feature aluminium construction with EnergyPlus uPVC top caps for superior thermal performance. The innovative Glazing Stop retainer ensures perfect glass alignment while maintaining weather tightness. Available in five classic styles including lean-to, gable, and Edwardian, with optional solar control and self-cleaning glass technologies for enhanced functionality.
Garden Rooms
Our Spaces garden rooms are engineered for year-round use with high-performance insulation and weather-resistant construction. The modular design allows complete customisation with optional electrical integration and multiple configuration options.
