FAQs
Frequently asked questions.
How slim are slim-frame sliders?
Our slimmest interlocking sightlines are 20–35mm. Profile depth depends on the panel size and glass make-up, which we confirm against your structural opening before quoting.
What U-value can you achieve?
From 1.2 W/m²K on double-glazed slim systems and 1.0 W/m²K with high-performance triple glazing — meeting and exceeding current UK Approved Document L requirements.
Are these aluminium systems secure?
All sliding, bifold and pivot systems are PAS 24 / Secured by Design certified with multi-point locking and laminated outer panes on accessible openings.
What colours can I have?
Any RAL or BS colour, in matt, satin or textured powder-coat. Dual-colour finishes (different inside and out) are standard and free of charge.
Do you install across London?
Yes. We survey, manufacture and install across Greater London and the Home Counties with our own teams, coordinated with your structural engineer and builder.
What's the lead time for bifold or sliding doors?
Typically 6–10 weeks from approved order, depending on system, finish and glazing spec. Roof lanterns and pivot doors usually run at the longer end of that range.
