Windows
KJM Group offers a comprehensive range of uPVC, timber, and aluminium windows, including casement, flush casement, and sliding sash designs. Our energy-efficient windows enhance thermal performance, reduce noise, and improve security while maintaining aesthetic appeal. Each installation is tailored to meet individual property requirements, ensuring durability and compliance with building regulations.
Conservatories
We design and install bespoke conservatories, including Edwardian, Victorian, Gable, and P-shaped styles. Our structures combine modern insulation technology with traditional aesthetics, creating year-round usable spaces. Customisation options include colour choices, glass specifications, and integration with existing architecture for seamless extensions.
Doors
KJM provides composite, uPVC, and aluminium doors engineered for security, durability, and style. Our installations include front, back, French, and patio doors, featuring advanced locking systems and energy-efficient glazing. Each door is custom-made to fit precise measurements, enhancing both functionality and kerb appeal.
Conservatory Roofs
We specialise in upgrading conservatory roofs with thermally efficient solutions, including Livinroof systems. These roofs offer superior insulation, noise reduction, and natural light integration while complying with building regulations. Our installations transform outdated conservatories into comfortable, energy-efficient spaces.
Triple Glazing
Our triple-glazed windows and doors provide enhanced thermal efficiency, reducing energy bills and noise pollution. Using advanced glass technology, we deliver solutions that meet rigorous performance standards without compromising on design flexibility or visual clarity.
