ThermalHeart+®️ components

The ThermalHEART® polyamide barrier insulates the frame of the window system, separating warm and cold areas. Using clean, modern lines, these frames provide high performance in extreme weather conditions. ThermalHEART® frames deliver almost double the thermal performance of standard aluminium windows and doors1

Explore ranges

The ATS-Architectural Thermal Spacer® reduces the transfer of hot and cold temperatures. Argon gas creates an additional barrier to heat loss and improves insulation. Solux-E® is a low emissivity (Low-E) coating that reduces heat loss in winter and over-heating in summer. It protects your home's interior while providing a similar clarity to clear glass.

Explore state-of-the-art glass

The Centrafix™ installation method recesses the joinery into the building wall, aligning the insulation elements - wall, window frame, glazing – to prevent cold air from circulating around the frame. This New Zealand designed innovation increases the thermal performance in your home by over 20%2 (see here for technical details).

1 Comparison figures are based on complete thermal modelling of an average house lot of Metro Series ThermalHEART® products with The AGP System® double glazing using the WEERS modelling methodology. The benchmark figures were calculated by modelling the same average house lot of products using the equivalent non-thermally broken products glazed with standard double glazing. A “standard aluminium window or door” refers to a non-thermally broken aluminium frame with standard double glazing.

Centrafix™ comparison figures are based on complete thermal modelling of an average house lot of products installed in 90mm timber framing. The standard installation benchmark was calculated by modelling the same house lot of comparable products using a typical E2/AS1 cavity construction installation on 90mm timber framing.

Windows

Awning Windows

   

  • Awning windows can be used in most positions and are ideal for New Zealand's changeable weather - they provide excellent ventilation
  • In-built strength, don't twist or flex when opened
  • Fanlights to provide ventilation and security.

Bi-fold Windows

   

If you want to make the most of your dramatic views or enhance your “indoor/outdoor flow” bi-fold windows are the answer. Bi-fold windows run on an easy-slide track system which allows for wide openings onto decks or patios.

  • Range from 2 to 6 panels wide, giving up to 4m of unobstructed view
  • Carry the weight on the bottom roller thus preventing panels from jamming
  • Maximum panel weight of 40kg applies.

Casement Windows

   

Because of their traditional look casement windows are especially popular with renovators. Casement windows are side opening and can catch the breeze and direct it inwards. In exposed positions casement windows may be forced wide open in strong wind gusts. This can be prevented with the use of restrictor stays which can limit the opening in these situations.

  • In-built strength
  • French casements are an option with no centre post
  • Friction stays available to provide 90° opening to allow easy cleaning of the outside.

Horizontal Sliding Windows

   

Horizontal sliding windows are ideal when you need a window that doesn't project onto walkways or patios. Single or double sliding panels meeting in the middle are available, as well as a double slider window where two panels on parallel tracks stack behind each other.

  • Strong panels for strength and durability
  • Heavy duty Slidemaster version for demanding environments and very high wind zones
  • Insect screens work well in conjunction with sliding windows making them ideal in cases where insects are a problem and exterior mesh screens are required.

Vertical Sliding Windows

   

Vertical sliding windows can either be double hung aluminium sliders or all glass Shugg sliders - two counter-balanced panes of glass which slide past each other with no aluminium rails to obstruct the view. Double hung windows have two surrounding frame options - a scrolled Edwardian appearance or a clean, flat contemporary look.

  • Double hung sliders can pivot inwards to allow for easy cleaning
  • Maximum size for each sliding panel is limited to 20kg.

Doors

Bi-fold Doors

   

By using Bi-Folding doors you can make the most of dramatic views and welcome breezes or enhance your indoor/outdoor flow. Bi-fold doors open up the full potential of your outside living by stacking out of the way to one or both sides.

  • Feature a bottom roller which carries the door weight at the sill of the frame, this avoids extra lintel loading and results in smoothly operating doors
  • Can include a free-swinging hinged door for easy access without opening up the bi-folds
  • A hold back device can be attached to free swinging doors to conveniently fix back to the next bi-fold panel
  • Follow the design of the hinged and French doors to ensure a co-ordinated look.

French Doors

   

French doors are classically elegant and ideal for outdoor living areas and add a stylish touch to your home. They are ideal where wide access to decks or other outdoor living areas is required.

  • The simple, modern look of the square-edged stiles is further enhanced by the clean overlap where the doors meet
  • Can include sidelights, overlights and adjacent windows
  • The bottom rail can be doubled in depth for the true French door look
  • Mirror the good looks of the hinged door and bi-fold door
  • Can be supplied with curved tops if desired.

Hinged Door

   

Hinged doors are often the most frequently used doors in your home and provide a less formal entranceway to your house. Usually used as back doors or utility doors.

  • Clean cut, square-edged stiles and wide top and bottom rails which can be further widened if required
  • Square cut rails and hidden compression blocks at the corners provide strength and stability
  • Sidelights, overlights and adjacent windows can be included
  • Either open in or open out doors are available
  • Mid-rails or glazing bars available
  • Full height safety glass doors can also be supplied.

Sliding Door

   

Sliding doors are excellent for indoor/outdoor flow leading on to decks or patios, and are also great space savers as all door movement is fitted inside the frame. They have the advantage of offering partial opening for ventilation without the danger of slamming.

  • Option of a double slider which has two sliding panels within a frame giving a choice of which to open
  • Multi Slider Doors - open to two-thirds of their width so are ideal for a wide opening to the outside. Are available in two formats - a 3 panel unit with two stacking panels or an ultra-wide 6 panel unit with 2 panels stacking towards one jamb and two towards the other.
