Who we are

Accent Doors and Windows Scotland Ltd​

We’ve been providing Eco friendly window products to the construction industry. Today we operate all around the UK supplying a range of windows composite timber aluminium, fibreglass reinforced solutions and full aluminium.

Over the years, we’ve developed an in-depth understanding of the local market, allowing us to build strong professional relationships and help our clients bring their visions to life. Our reputation has been earned by listening carefully to our customers and truly understanding their objectives.

Only once we fully grasp the design intent can we recommend the windows and solutions that best complement the overall concept, ensuring both performance and aesthetic excellence.


Construction

Composite Bonded Construction

Advantages

The Technical Advantages of the Leiab System

Leiab windows utilise a permanently bonded aluminium–timber composite structure. This engineered system ensures that the external aluminium cladding fully protects the timber core from direct exposure to moisture and weathering. When the window is closed, no timber is exposed to the elements.

Integrated concealed drainage channels and weep holes allow rainwater to be effectively directed away from the frame, preventing moisture retention and eliminating the common durability issues associated with traditional timber-only systems.


Interior Finish

The internal frame provides a high-quality natural timber finish, manufactured from close-grained Scandinavian pine as standard. Alternative timber species are available on request.

Internal surfaces may be:

  • Factory painted (RAL/NCS)
  • Stained
  • Clear lacquered
  • Custom finished to specification

This allows full coordination with interior architectural schemes.

External Aluminium Profiles

A comprehensive selection of aluminium profiles is available to suit both contemporary and traditional architectural styles.

  • 4 primary frame and outer arch models
  • Configurable into 16 distinct external combinations
  • 4 alternative internal profile options

This modular design flexibility enables precise aesthetic integration with project requirements.

Bespoke Dimensional Manufacturing

Every unit is manufactured to exact millimetre dimensions as standard, with no surcharge for non-standard sizing.

Benefits include:

  • Improved installation efficiency
  • Reduced need for on-site adjustments
  • Enhanced air and weather tightness
  • Accurate alignment within structural openings

Glazing Options

All units are internally glazed to specification, providing enhanced security and thermal performance.

Available configurations include:

  • Triple glazing
  • 2+1 configuration
  • 3+1 configuration
  • Double frame systems

Specialist glazing options available:

  • Privacy glass
  • Solar control
  • Acoustic performance glazing
  • Safety and laminated glass

Thermal Performance

High-performance glazing and composite construction deliver excellent energy efficiency.

  • Whole window U-values from 0.8 W/m²K
  • Reduced thermal bridging
  • Enhanced internal surface temperature stability

This contributes to improved occupant comfort and lower energy consumption.

Acoustic Performance

Designed for environments where sound insulation is critical:

  • Suitable for urban, roadside, or high-noise locations
  • Sound reduction performance up to 69 dB (depending on glazing specification)

Durability & Longevity

  • External aluminium requires minimal maintenance
  • Timber core protected from UV and moisture exposure
  • Concealed drainage system prevents standing water
  • Long design life with dimensional stability

Leiab Triple Glazing Systems

Leiab offers two distinct triple-glazed systems:
Epok – A traditional, detailed profile suited to heritage and character properties.
Stil – A clean, contemporary profile with crisp architectural lines.
Both systems deliver outstanding thermal, acoustic and structural performance within Leiab’s bonded timber–aluminium construction.

Engineered for Longevity

A saw-cut section of a Leiab window removed after approximately 40 years in service shows no evidence of timber rot — a testament to the effectiveness of the bonded aluminium protection system and concealed drainage design.

Leiab provides a 25-year guarantee covering timber, aluminium, and powder coating.

With over one million windows and doors installed worldwide, the system has a proven long-term track record.


Innovative technologies

energeto® neo is a concept based on innovative aluplast technologies:
Powerduer inside replacing steel reinforcements with composite reinforcements,
Bonding inside, i.e. the technology of gluing the glass unit into the sash glazing rebate.
Safetec inside, a system with a classic middle seal
Foam inside, i.e. the optional possibility of filling the profile chambers with thermal insulation materials


The aluplast Lift-and-Slide door achieves U-values as low as 0.65 W/m2K. that’s a Passive Haus equivalent standard performance!

Slim sightline modular 85mm system
Modular – available in entry, standard and premium options
U-values as low as 0.65 W/m2K
Maximum sash weight of up to 300kg!


Technical Support

Our Technical Team are at hand to help you specify the correct product for your project. They will guide you at each stage on the use of products, samples, drawings and specifications. Our technical and design service includes

  • Product selection and application
  • Technical review to confirm compliance with Building Regulations, including Document L
  • Advice on exposure conditions
  • Wind load calculations
  • Framing construction and design solutions
  • Generation of scheme drawings for tendering purposes
  • Technical specification
  • Window samples for client/authority approval

A well‑defined specification is a critical foundation for any design process. When a specification is poorly written, it can create significant challenges for everyone involved in the project and ultimately lead to costly consequences for the client.

A strong, carefully prepared specification, however, supports smoother project delivery, reduces risk, and can generate substantial savings. Accent Doors and windows Scotland Ltd  provides support across construction projects of all scales, offering expertise from initial concept through to final completion.
