Glazed Extension
Our Glass Roof, combined with performance glass and either masonry piers or super-insulated columns, provides both structural solidity and the thermal efficiency needed for a house extension. The glass roof also maximises natural light and creates a spacious atmosphere, delivering a true ‘wow’ factor.
- Super-insulated columns allow for increased glazing in your orangery extension while ensuring compliance with building regulations.
- Super-insulated columns paired with bi-fold doors create a contemporary appearance.
- A glass roof reduces solar gain and retains heat, helping to prevent fabric fading and maintain a comfortable temperature in your orangery extension.
- Each extension includes at least four large corner columns, with additional in-line columns as required by the design or size.
- The insulated perimeter pelmet is 800mm deep and filled with 100mm of mineral fibre insulation.
- Choose from uPVC, aluminium, or Ultrasky roof options.
- Each structure is engineered to meet the specific requirements of your postcode, ensuring peace of mind.
- For added solidity and warmth, select brick pillars and walls.
Livinroof Extension
Livinroof house extensions combine the advantages of solid and glass conservatory roofs. This system allows you to add glazing in any location or shape, offering design flexibility. Livinroof can create a focal point in your orangery or house extension, helping it stand out.
- Livinroof extensions are highly thermally efficient and meet Building Regulations, allowing for the removal of internal doors.
- Each extension includes at least four large corner columns, with additional in-line columns as required by the design or size.
- The contemporary Livinroof design complements bi-fold or sliding doors.

Inside, the Ultraroof features a vaulted plastered ceiling, while the exterior showcases authentic-looking lightweight tiles. Optional full-glazed panels can be added to enhance natural light and create a striking visual feature.

Excellent service from start to finish, we had secondary Glazing fitted into our dental practice. Glevum attended when they said they would, completed the job with minimum disturbance to the daily running of the practice, and left their work place clean and tidy. The glazing has made such a difference, staff are much warmer and the radiators have been turned to low.
