Overview 

## What we do, who it's for, and why it matters.

### What it is

Curtain walling is a non-loadbearing aluminium-framed glazed envelope hung from the building's structural frame. It carries only its own weight plus wind and impact loads — never the building's vertical loads — which allows the entire elevation to be glazed across multiple storeys.

### Who it's for

Main contractors, architects, commercial developers, public-sector estates teams and building refurbishment specialists working on offices, education, healthcare and mixed-use commercial projects across Scotland.

### When you need it

You need a curtain wall specialist at new-build (designed in from RIBA Stage 3), at major refurbishment where envelope replacement is part of the scope, or at end-of-life of an existing system (typically 30–40 years for first-generation systems).

### Why a specialist matters

Curtain walling is the building envelope. Specification governs U-value, air permeability, water tightness, wind resistance and impact rating — all tested to BS EN 13830. Get any of those wrong and the building leaks, costs more to heat, or fails CDP testing — none of which are fixable retroactively without major cost.

The Cost of Inaction 

## What happens when the problem is left.

Curtain wall failure is rarely visible from outside until water has tracked into the structure. The cost of remediation is almost always an order of magnitude greater than the cost of correct specification.

### Water ingress and structural damage

Failed perimeter seals or compromised pressure-equalised drainage tracks water into the slab edge — often invisible until interior finishes show damage.

### Thermal underperformance

Cold-bridged framing or single-glazed legacy systems can leak 40%+ of envelope heat — a permanent operating cost penalty.

### Air permeability failures

Curtain walling tested to BS EN 13830 must achieve specified air loss rates — failure on commissioning means rework before practical completion.

### Design liability for installer

Installer-designed elements (brackets, fixings, transom drainage) carry CDM design liability — non-specialist installers create unmanaged risk.

### Common mistakes we're called in to correct

-   Treating curtain walling as a glazing trade instead of a structural envelope discipline. 
-   Specifying suite without checking spans, deflections and thermal performance for the project. 
-   Skipping CWCT pre-construction testing on bespoke systems. 
-   Using sealants and gaskets outside manufacturer-approved compatibility lists. 
-   Programming curtain walling without the main contractor lift and crane plan agreed. 

Our Process 

## A disciplined five-step delivery — survey to certification.

01

### Pre-Construction Engagement

We engage at design stage with the architect and main contractor — system selection, performance targets, structural interface and procurement programme.

02

### Design & Calculation

Suite selection, mullion and transom sizing, structural calculation, thermal modelling and CWCT performance specification produced.

03

### Procurement & Fabrication

Frames procured and pre-fabricated to project dimensions; unitised systems factory-glazed where appropriate to compress site programme.

04

### Installation

Installed in coordinated lifts with main contractor, sequenced to follow structural frame completion. Transoms, mullions, glazing, gaskets and pressure plates installed to manufacturer specification.

05

### Testing & Handover

On-site water and air tightness testing where specified; full O&M documentation, performance certification and snagging close-out.

Benefits 

## What you get — concrete, not generic.

### Engineered envelope performance

U-values, air permeability and water tightness specified, modelled and tested — not assumed.

### Programme certainty

Unitised options compress on-site time; factory-glazing reduces weather risk.

### Single trade interface

We coordinate with structural, M&E, cladding and roofing trades — main contractor manages one specialist.

### Architectural flexibility

Slim mullions, structural glazing, feature fins and capped or gasketed appearance options.

### Scotland-wide delivery

We mobilise to projects across Scotland from our Falkirk base, with established subcontract teams.

### Long design life

Aluminium curtain wall systems are typically designed and procured for 35-year service life with planned recurring servicing.

Specification Detail 

## The detail that separates a 15-year asset from a 3-year liability.

Modern curtain walling is a tightly regulated discipline governed by BS EN 13830, CWCT (Centre for Window and Cladding Technology) standards, and CDM design liability. The system, the installer and the test regime are all specified together.

### Materials we work with

-   Thermally-broken aluminium mullions and transoms (Smart, AluK, Comar, Senior, Reynaers, Schueco) 
-   Sealed double or triple-glazed units with low-emissivity coatings and warm-edge spacers 
-   Structural silicone for SSG (structural silicone glazed) systems 
-   EPDM gaskets and tested perimeter sealants per system manufacturer 
-   Powder-coated and anodised finishes to BS EN 12206 / BS 3987 
-   Insulated spandrel panels for non-vision areas 

### Methods & systems

-   Stick-build systems — components delivered and assembled on-site, suitable for low to mid-rise 
-   Unitised systems — factory-glazed storey-height units lifted into place, suitable for mid- to high-rise 
-   Capped, gasketed or structural silicone glazed (SSG) appearance options 
-   Pressure-equalised drainage design to BS EN 13830 standards 
-   On-site CWCT-standard water and air permeability testing 
-   Coordination with main contractor scaffold, lift and crane programmes 

### Variations of this service

#### Stick-build curtain walling

Mullions, transoms and glazing assembled on-site. Most common for refurbishment, low to mid-rise commercial and where opening sizes vary.

#### Unitised curtain walling

Storey-height units pre-fabricated and glazed in factory, lifted into place via crane. Common in mid to high-rise where programme compression matters.

#### Structural silicone glazed (SSG)

Glass bonded to frame with structural silicone, eliminating external pressure plates for a flush all-glass appearance.

#### Spandrel and shadow box panels

Insulated non-vision spandrel zones between floor slabs, finished with coloured back-painted glass or aluminium panels.

#### Replacement and overcladding systems

Specialist solutions for refurbishment of existing 1960s–1990s building envelopes without full demolition.

### Where this applies

-   New-build commercial offices across Glasgow and Edinburgh 
-   Higher and further education building envelopes 
-   Healthcare estate atrium and elevation glazing 
-   Public-sector building refurbishment 
-   Mixed-use developments combining retail ground-floor and residential or office above 
-   Industrial admin and HQ buildings on distribution and manufacturing sites 

Complete Door Solutions delivers curtain walling across Scotland on commercial new-build and refurbishment programmes — engaging early with the design team and main contractor to deliver a tested, certified building envelope to programme.
