The Flagship Aluminium Window.
Schüco AWS 70.HI is the high-insulation version of the world’s most specified aluminium window platform. Built on a 70mm basic depth with fully concealed fittings, it pairs slim sightlines with near-limitless configurations — from a single casement to whole ribbon facades — and the thermal performance modern building standards demand.
German engineering, quietly at work.
Every AWS 70.HI window is fabricated to order and fitted by our own installers. Four reasons architects and homeowners keep specifying it.
Engineered insulation
Uf values from 1.5 W/m²K, with glass down to 0.5 W/m²K in triple glazing. A high-insulation core built for energy-efficient building envelopes.
Slim and concealed
A 51mm outer frame and 40mm vent keep sightlines slim, while fully concealed fittings leave clean, uninterrupted lines inside and out.
Every way to open
Turn/tilt, side-hung, pivots, projected top-hung, toplights and barrier-free window doors — with optional TipTronic electromechanical operation.
Certified strength
Burglar resistance up to RC3, Class 9A watertightness and vents carrying up to 200kg of glass. Strength that is tested, not claimed.

How long does installation take?
Most window installs are completed in 1-2 days. Doors typically take 1-3 days depending on threshold work. Full-house or multi-room replacements run 3-7 days. We give you a precise schedule at the survey stage so you can plan around it, no open-ended jobs.
Is the installation FENSA-registered, and do I get the certificate?
Yes. Apex Glazing is FENSA-registered (Reg 40373). On completion you receive a FENSA certificate, which satisfies Building Regulations Part L compliance and removes the need for separate council approval. Certificates are issued within 30 days and stored in your FENSA online account for future house sales.
What warranty do I get?
10-year manufacturer warranty on the product itself (frame, glass seal, hardware) plus a 12-month workmanship guarantee from us on the installation. We've been trading since 2005 with 6,340 completed projects and a 5.0-star Google rating, we'll come back if anything's not right.
Do you remove and dispose of the old windows or doors?
Yes, removal of existing units, safe disposal at a licensed waste facility, making good of internal and external reveals, and a thorough final clean-up are all included in the quoted price. There are no extras for skip hire, scaffolding, or waste removal.
Can you match existing windows for a phased replacement?
Yes. We can RAL colour-match the new frames to your existing units, replicate sightlines, glazing bar layouts, and hardware style to keep a phased replacement consistent. Bring photos to the survey, or we'll come and measure the existing windows so the new ones blend in seamlessly when fitted alongside.
