What does thermally broken aluminium mean?

Thermally Broken Aluminium Framing: A Thermally Broken Frame is one which features a reinforced polyamide strip (a non metallic, composite, structural, material) fixed between the inside and outside aluminium profiles, creating an insulated barrier within the window frame.

Are aluminium doors thermally efficient?

Thermally broken aluminium windows and doors provide exceptional thermal performance, reducing your energy bills whilst keeping your home well insulated all year round.

What does thermally broken doors mean?

A thermal break is a barrier or “break” in a window or door frame. Thermally broken door systems are used whenever there is a difference between indoor and outdoor temperatures. Metal is an excellent conductor of heat and cold, meaning that you can lose a great deal of heat through a door frame.

Why do aluminum doors need a thermal break?

Standard aluminium is a good conductor of heat and cold meaning that you can lose or gain a great deal of heat through the frame of the window/door. This can ultimately undermine the performance of double glazed windows. A thermal break needs to be added to the frame.

How much more expensive are thermally broken windows?

So you have been given the bad news by your energy rater, your new build needs thermally broken windows, you can expect that this will add 50% – 100% to the cost of your windows.

What is thermal break in doors and windows?

Insulation within a window is referred to as a “thermal break”. The thermal break is a continuous barrier between the inside and outside window frames that prevent conductive thermal energy loss (see the image above). The barrier securely bonds the interior and exterior metal frames of the window sash.

What is the thermal break in aluminium windows?

A thermal break is simply a piece of material positioned within an aluminium window frame to minimise heat loss. It separates the aluminium frame into two separate interior and exterior sections, combined with less conductive materials such as polyamide or polyurethane.

What is a thermal break on an aluminium window frame?

A thermal break is defined as a material with low thermal conductivity placed in an extrusion with the purpose of reducing the flow of thermal energy (heat). In aluminum windows, three types of thermal breaks are used. A standard pocket thermal break has been used in the window industry for decades.

What is the difference between thermal break and non thermal break?

Thermally broken metal windows provide several benefits over non-thermally broken systems and the basic difference as stated by most experts is “improved overall thermal performance over traditional non-thermally broken systems.” The most important factor in deciding to have a thermal break to a frame is that it will …

How does a thermal break work?

Thermally broken window frames are insulated against heat and cold conduction. This is done by separating the outside metal parts from the inside with a material which reduces the amount of heat or cold transferred through the frames. This feature is known as the “thermal break”.

What is the purpose of a thermal break?

A thermal break is a material with low thermal conductivity, placed in an assembly, to reduce or prevent the flow of thermal energy between the inside and outside of a building.

How do I stop thermal bridging?

To combat the problem of thermal bridging, the studs must be covered with continuous insulation. During home construction, insulation can easily be added to the wall system to break the thermal bridge. In a remodeling situation, a layer of insulation can only be added from the inside or the outside of the home.
