Frequently Asked Questions

What sliding door systems do you install?

We install the Cortizo Cor Vision Sliding with 20mm sightlines and the Schuco ASS 70.HI achieving U-values from 1.1 W/m²K. Both are PAS 24 certified for security, and every installation is FENSA registered with a CPA insurance-backed guarantee.

How much do aluminium sliding doors cost?

Final price depends on the system (Cor Vision Sliding, Cor Vision Plus Sliding, 4900 Sliding HI, Schuco ASS 77 PD), opening size, panel count, glazing spec and any motorisation. Every installation includes FENSA registration and a 10-year CPA insurance-backed guarantee. Request a free no-obligation quote.

What's the maximum panel size?

The Cortizo Cor Vision Sliding handles individual panels up to 400kg, allowing panels up to 3 metres wide and 3 metres high.

Sliding doors vs bifold doors?

Sliding doors offer slimmer sightlines and don't require space to fold. Bifold doors create a wider opening. We can advise which suits your property best.

What guarantees do you offer?

Cortizo Cor Vision Plus Sliding and Schuco ASE 80 / ASS 77 PD Panorama sliding doors carry a 10-year manufacturer warranty against frame integrity, hardware operation and finish. Every Vitrum Solutions installation is FENSA registered against UK Building Regulations, and the workmanship is covered by a separate 10-year CPA insurance-backed guarantee, which protects you even if our company ceases trading.
