Application

Innovative or traditional new builds and renovation/extension projects where performance is critical.

Description

The Denali single, stable and French doors were designed around triple glazed vacuum glass. This unit is considerably thinner than effective triple or quadruple glazing units, which allows replication of style and sections of a traditional British door profile, while also achieving extreme energy efficiency. A highly traditional beading detail is incorporated to give the doors a classically styed appearance.


Frontier Range of Performance Doors:

Designed to target the future build market, but without the typical downsides of super-efficient products, the Frontier range is an advanced window range. Constructed from FSC-Certified Accoya® with a proprietary vacuum cavity unit and a specially adapted Italian paint system the range combines energy efficiency and an extended low maintenance service life into a well-designed package suitable for most styles of building.


Denali Performance Timber Entrance Door Range:

  • Vacuum cavity glazing combined into a proprietary triple glazed unit, delivering centre pane U-values of 0.4 W/m²K. Thinner unit allows for more traditional window dimensions and better aesthetics.
  • All traditional shapes and sizes are available, including entrance doors, single doors, French doors and stable doors.
  • All panels are constructed using insulated sandwich boards. This delivers a considerable improvement in energy efficiency over traditional doors without impacting the appearance.
  • Full multi-point locking system. These locks deliver good security and help to prevent bow or twist in the door leaf during acclimatisation.
  • Ironmongery is included with a range of modern and heritage styles and finishes. French doors include cabin hooks as standard.
  • High quality ball-bearing butt hinges give long life span and excellent functionality. Shims behind the hinges are included for easy adjustment during installation or acclimatisation.
  • Clapping strips included as standard on French door-sets delivers exceptional air-tightness.
  • Dummy top and bottom rails included as standard in side panels.
  • Door leafs made from Accoya® as standard to give extreme stability and reduce the need for seasonal adjustment.
  • Slender 22 mm glazing bars and thin profile of the beading reduce the perceived width of the sections. External bar designed to replicate the traditional appearance of putty pointing.
