An insulated steel doorset delivers far more than a simple thermal barrier against the cold. The double skinned steel construction dramatically improves the overall acoustic properties, physical integrity and long term security of the entrance. This rigid manufacturing method ensures the door performs flawlessly in heavy traffic commercial environments without warping, cracking or dropping over time.
The physical strength of two steel skins firmly bonded to a dense insulating core creates an incredibly strong door panel. It naturally resists twisting or bending during a brute force entry attack. This inherent structural rigidity also drastically extends the operational lifespan of the doorset. It keeps heavy duty hinges, frames and multi-point locking hardware perfectly aligned over decades of continuous industrial use, which significantly reduces your ongoing maintenance costs.
Part L of the UK building regulations now requires a strict minimum U-value of 1.6 W/m²K for external doors on new commercial buildings. Our insulated doorsets easily exceed this target to help reduce daily carbon emissions and expensive commercial heating costs. The dense internal core stops heat escaping during winter while keeping the internal workspaces cooler throughout the summer months. It also acts as a highly effective acoustic barrier against heavy industrial or traffic noise.
If you are specifying an external emergency exit or high security door, adding insulation makes logical sense. The UK fire safety sector is rapidly shifting towards strict European 'EI' certification. This means the doorset actively prevents the physical spread of flames while also stopping dangerous heat transfer through the metal face. Choosing insulated fire doors today effectively future proofs your premises against tightening safety legislation while immediately reducing your energy bills.
We supply one of the widest ranges of insulated steel doors in the UK, which can easily be paired with our insulated roller shutters and sectional doors for a complete perimeter solution.
