Home — Thermal-break aluminium windows & doors

Slim aluminium frames.
Serious energy savings.

We design, manufacture and install premium thermal-break aluminium windows, doors, sunrooms and curtain walling. One team from survey to sign-off.

What we do

Two ranges. One warmer, quieter, better-sealed home.

Windows and doors are the same problem viewed from two sides — the frame, the glass and the seal. We make both in the same factory, to the same tested standard.

Solar Energy Saver

The building we glaze can also make its own electricity. We supply and install grid-tied, hybrid and off-grid solar systems with battery storage — from a 3.5 kW house system to a 500 kW commercial plant — specified the same way as our glazing: measured, calculated and written down before you commit.

☀Modules 440–800 W N-type TOPCon, HJT and bifacial double-glass modules up to 24.8 % efficiency.
⚡Inverters 3.5–500 kW On-grid, hybrid and off-grid, single and three-phase, with 10 ms changeover on the hybrid range.
▮Storage 4.8 kWh – 3.6 MWh LFP wall and rack batteries, cabinet ESS and containerised systems for commercial sites.

Who we work with

Two kinds of customer, two ways of working

The products are the same. The paperwork, the lead times and the person you deal with are not — so tell us which one you are and we will quote the right way round.

Residential

Homeowners & renovations

One house at a time. We survey, design, manufacture and install, and you deal with the same person from first visit to final adjustment.

  • Window and door replacement, whole-house or room by room
  • Bi-fold and sliding doors for extensions
  • Sunrooms, roof lanterns and skylights
  • Free survey, fixed written quote, no deposit to book

Typical project: 8–20 windows and a door set, surveyed in one visit and installed in two to four days.

Commercial & trade

Contractors, developers & specifiers

Supply-only or supply-and-fit, priced off drawings, scheduled to your programme. We can work to your specification or write one that meets the performance you need.

  • Curtain walling, shopfronts and commercial entrances
  • Multi-unit residential developments, priced per plot
  • Loose hardware and profile supplied to the trade
  • Automatic garage doors and shutters

What we need to price: elevations or a window schedule, the performance spec, and your programme dates.

Why Global Solution Trading

Specified properly, or not at all

Most quotes are a price per opening. Ours begins on the drawing board — glazing build-up, frame sightlines, thermal-break profile and tested air and water figures, agreed before anything is committed. Because a beautiful window in a badly specified system still costs you money every winter.

01

We specify before we quote

Full survey and glazing spec, with the tested performance figures for the exact profile written down.

02

We manufacture what we install

Our own workshop, our own fitting teams. No subcontractor gap when something needs putting right.

03

Fixed price, fixed date

The quote you sign is the invoice you pay. Installation dates are confirmed in writing before deposit.

04

Aftercare that answers

Annual adjustment service and a direct line to the team who fitted it.

How it works

Four steps, no surprises

01

Free survey

We measure every opening, check the reveals and record the structural openings on site.

02

Fixed quote

An itemised specification — profile, glazing, U-values and hardware — at a price that does not move.

03

Manufacture

Your frames are cut, welded and powder-coated to order. Typically 4–6 weeks, and we keep you posted.

04

Install & hand over

Clean, protected installation, full adjustment of every sash and a walkthrough before we hand over.

Questions

Things people ask before they book

Why aluminium instead of uPVC?

Aluminium is far stronger, so the frame can be much slimmer for the same structural span — typically 30% more glass in the same opening. Modern polyamide thermal breaks close the old insulation gap, and a powder-coated finish will not yellow or warp. It also lasts decades longer, which is why it is standard on architect-designed homes.

What performance figures do you publish?

Every profile is quoted with its tested figures: water tightness up to 700 pa, air tightness from 1.2 m³/(m·h), wind pressure resistance to 5 kPa, acoustic performance to 40 dB and U-Factors from 0.23. The tested values for the exact system you order are written into the specification.

How long does installation take?

Manufacture is typically four to six weeks from the signed survey. A normal house of 8–20 windows and a door set is installed in two to four days by our own fitting teams — no subcontractors.

Can you match a specification or an architect's schedule?

Yes. Send the elevations or the window schedule with the performance spec and we will price against it profile by profile, or write a specification that meets the performance you need.
