Manual and Fire Doors

Internal or external manual doors are very common and feature in every building. These can become worn, damaged and starting losing their self closing strength over time. A simple repair can usually resolve any issue and put the door back into full working order. Door material usually in wood, aluminum or steel, with or without lite kits and glass, or windows.

Internal fire doors help slow the spread of fire & smoke allowing vital extra time to make your exit from the property. Most new builds require the addition of Fire doors. All fire doors are all CE marked and CERTIFIRE approved.

Existing fire doors can be upgraded by installing new panic bar systems and latching points on to existing fire doors to create a safe means of exit.

Full or partial glass doors are ideal for well traveled corridor doors. We make sure that windows comply with Part M regulations on minimum zones of visibility. It is essential that the doors have a window to provide safety and allow others to see people on either side of the door.

Full glass doors, offer additional source of natural light, and can add aesthetic and monetary value to a building. They work well with full glass partitioning, offering an office with open plan views.
