Thermal-Break vs Non-Thermal-Break Aluminum Windows: Cost, Performance and Applications

A thermal break is worth something when it solves a problem with the building envelope. Paying for a label and then not defining climate, whole-window performance requirements or glass specification is a waste of money. So, this is not a comparison between premium and cheap. It’s a comparison between two different frame types for different spaces, comfort levels and compliance requirements.

We manufacture both non-thermal-break and thermal-break configurations. Our non-thermal-break aluminum casement window is our 50 Series, the 108 Series thermal-break casement window with integrated mesh and the 128 Series double thermal-break are also part of our range. We build from the project, not from the perspective of forcing all openings to fit within one of our system configurations.

What the thermal break changes

Aluminum is a good conductor of heat. Non-thermal-break profiles contain interior and exterior aluminum surfaces joined together as a solid frame. These frames act as a single conductive path. In contrast, thermal-break frames contain a low-conductivity barrier which separates the inner and outer aluminum sections of the frame. This increases the frame’s resistance and in cold weather will improve interior surface temperatures.

The window frame is only part of a window and many other components such as glass, spacer, seals, sash size and type, opening type and installation details all affect the overall performance of a completed window. Our U-factor, SHGC and Low-E guide explains why one must not mix and match Uw, Ug and Uf values in a quote. Even a supplier offering very low glass Ug values has not necessarily demonstrated a low Uw value for the complete window.

Performance: comfort, energy and condensation

If there is a large difference between inside and outside temperatures for extended periods of time, choose a thermal-break window. By breaking the strong conductive bridge of aluminum, it allows for a more even surface temperature on the room side of the frame. While indoor humidity, outside temperature and a number of other installation factors can affect condensation on the frame, a thermal-break window can help reduce the instance of frame condensation.

In a cooling-dominated climate, the thermal break can serve to reduce inward conductance as well as solar gain through the glass. While the frame cost would be better spent elsewhere, the frame can be a reasonable cost if paired with an appropriate Low-E coating and solar factor rather than spending the entire budget on the frame with no definition of the glazing. For example, an east- or west-facing elevation may have significantly greater solar gain than heat conduction through the frame.

Cost: compare the scope, not a universal percentage

The use of thermal-break profiles requires additional materials, component assembly and verification. Also, whilst using a thermal-break profile, deeper frames, more robust hardware and better insulated glazing units can be specified. The additional cost therefore can vary considerably depending on the section weight, barrier design, glass specification, finish, hardware, order quantity, tests and any customization required. Therefore a fixed percentage increase such as thermal break costs 30% more than non-thermal break than this needs to be compared on like for like bills of materials.

Request two quotations on the same dimensions and opening schedule. Keep the glass, finish, hardware, screen, packing and delivery terms identical. Then the frame-system difference becomes visible. Also compare expected use: an air-conditioned apartment may justify the higher envelope performance, while an unconditioned interior partition will not recover that value.

Where each system fits

• Thermal-break windowsshould be used for conditioned homes, hotels, offices, and apartments operating in cold, hot, or mixed climates.
• Apply thermal breaks wherever local building regulations or project model requirements call for a low U-value for the entire window.
• These may be used where there are problems with cold interior frame surfaces and condensation, which could damage finishes and/or create discomfort.
• Non-thermal-break systems can be considered for internal partitions, unheated storage, outdoor service areas and mild climate regions with low thermal performance requirements.
• Do not use non-thermal-break frames to reduce cost when specifications require a frame that can perform!

For non-thermal-break aluminum casement projects our 50 Series window can provide an adequate solution. For external conditioned openings, the 108 Series or 128 Series may be a more suitable starting point. The final choice will depend on a number of variables including the required Uw value, overall size, glass type, screen requirement and building exposure.

Do not ignore weather exposure

Don’t confuse thermal performance with wind or water performance for a coastal high-rise building. Sure, you need to select a suitable thermal-break frame but that doesn’t necessarily mean your windows can withstand the design pressure, or classify as suitable for air or water, and have the correct finish, suitable hardware and are installed correctly. We have developed a window selection guide for coastal and high-wind situations to help specify the additional requirements of your project.

A clean comparison request

Create one schedule outlining width and height, opening style, quantities and locations. Detail the required Uw or local energy rule, glass build-up, required solar-control performance, safety glass requirements, finish, hardware, screens etc. Test standards, packing and trade term also required and have each of the alternative products repeat these assumptions so that you can audit the decisions made as opposed to being provided with two prices for two different products.

Think beyond the purchase order

In addition to energy consumption, the frame decision influences factors like interior comfort near windows, the risk of cold-surface condensation, the required size of the HVAC system and the uniformity of the facade specification. An expensive frame does not compensate for a badly sealed perimeter joint. Therefore, include the installation details and the final fine-tuning in the quality plan so that the selected system has a fair chance to perform as intended.

Frequently asked questions

Q: Is a thermal-break window always better?

A: Use a low-thermal-conductivity material to reduce conductive heat flow through an external aluminum frame. This material may not be needed for interior partitions or for unconditioned spaces with no thermal requirements.

Q: Can double glazing make a non-thermal frame energy efficient?

A: The glass area does improve with double glazing but the continuous aluminum frame conducts heat transfer. Compare the complete Uw values not just the glass.

Q: Does a thermal break stop condensation?

A: This may slightly raise the interior frame-surface temperature but overall risk will decrease. Indoor humidity, outside temperature, edge of glass and thermal bridge due to installation are of greater significance.

Q: What creates the cost difference?

A: The profile, aluminum weight, thermal barrier, glass, hardware, finish, testing, quantity and packaging all play a role. Compare like configurations.

Q: Which PAVIDA series should I compare?

A: 50 Series non-thermal casement, 108 or 128 Series thermal-break alternatives. Match final system to project data.

Send your window schedule with the climate, required thermal value, glass, opening type and quantity. We can prepare comparable configurations and show which inputs drive the price difference.

Choosing the Right Aluminum Windows for Buildings in Coastal or High Wind Regions

When specifying a coastal window, it is useful to treat the salt exposure risks to finishes, hardware and dissimilar metal connections separately from the wind pressures that generate structural load, deflection and water driving forces. A single specification can then test that the chosen window meets all these requirements.

PAVIDA specializes in custom-made aluminum window and door systems for overseas projects. These can be projects located near the coast and in other parts of the world. By using the project location, the dimensions of individual units, the type of opening and the required tests, we can select the appropriate configuration. A generic “marine-grade aluminum window” description is not sufficient.

Define the coastal exposure

Distance from the coast is only an indicator. Exposure to corrosion is determined by a combination of airborne salinity, wind, humidity, rain, shelter, altitude and pollution near the building. ISO 9223 indicates corrosion protection classes by using environmental influences like time of wetness, sulfur dioxide and airborne salinity. Buildings of equal distance to the coast can have totally different deposition and drying conditions.

Does the facade face the sea, is it behind another building, gets directly washed by spray or can it get washed by rain? And what is the maintenance access like? A durable finish still needs to get salt off from time to time; a window that can’t get safely rinsed or inspected will get older faster than a similar window on a balcony that can be safely accessed. For a practical example, explore PAVIDA’s Perth coastal window project in Western Australia.

Specify the complete corrosion system

The aluminum alloy is only the basis for a finished product. Pretreatment and surface coating, coating thickness, cut edge protection, use of stainless steel or protected hardware, fastener compatibility and water drainage also determine the product’s durability. Incompatible metals in wet/salty areas must be isolated. Special attention needs to be paid to sealers, hinges, locks, screws and all concealed areas where material deposits can dwell.

Salt-spray test hours provide an indication of a coating’s consistency and potential defects, but the test is not intended to predict long-term service life or to rank corrosion resistance of different materials in real-life situations. Read the test scope, specimen preparation and acceptance criteria instead of attributing the sum of all hours run in test to some specific lifespan.

Learn more about PAVIDA’s window manufacturing and finishing process, including surface treatment, hardware assembly and quality inspections.

Convert wind into a design pressure

A simple declaration like ‘suitable for 150 km/h wind’ leaves too many questions open. The pressure of wind depends on a lot of parameters like place, height of the building, the surrounding terrain, the form of the building, corner situations and whether the load is pushing against the outside skin of the building or is pushing from inside outwards. The project engineer or the governing codes should supply the design load for the individual facade zones.

Map the specified load to the tested item. A test of a small fixed specimen does not automatically constitute testing of a tall operable sash. Inspect the tested specimen for width and height, for type of opening, for mullions, for glass, for reinforcement, for operating hardware and for anchors. Structural performance under uniform static pressure is covered by ASTM E330/E330M test methods; cyclic loading and windborne object testing, however, utilize separate test methods. For European projects, wind load testing is frequently associated with EN classification of air and water performance.

Glass, hardware and opening style move together

The thickness and make-up of the glass will need to be appropriate for the design load, the size of the individual panes, their support and for local regulations relating to safety. Where there is a risk of hurricane or cyclone, glass may also require to offer impact protection in addition to resistance to pressure. Laminated glass can often be substituted by alternative products but this should only be done following the specific impact and cyclic-pressure test route required by the project.

The opening style of a product has a significant influence on the required profile sealing and the corresponding hardware loads. Properly specified compression-sealed casement windows can offer effective weather sealing, while aluminum sliding windows provide space-saving operation but require careful attention to tracks, interlocks and drainage.

Water management continues into the wall

Wind-driven rain seeks out weak joints. Inspect sill upstands, drainage slots, pressure-equalization joints, gasket continuity, and corner joints. Frame-to-wall interfaces require compatible barrier membranes, backer rod, appropriate sealant geometry, and proper flashings. Ensure that all building parity drainage openings are left open post-construction and are not subsequently covered by render, masonry or decking.

In addition to approved anchors, the installer will require information on anchor spacings, edge distances and the substrate to which the anchor is to be fixed. Product testing describes a test specimen but performance at a site will depend upon successful reproduction of the appropriate support and sealing conditions. A site water test should be planned where the contract or exposure circumstances justify such a test.

A coastal and high-wind submittal checklist

• Project coordinates, building height, facade zone and engineer-supplied design pressure.
• Window schedule with actual sizes, fixed and operable areas, glass and mullions.
• Corrosivity exposure, finish system, hardware and fastener materials, and maintenance access.
• Air, water, structural, cyclic-pressure and impact requirements for destination markets.
• Full test reports mapped to the offered system and size, not isolated certificate pages.
• Installation drawings to be shown for anchors, perimeter seals, sill drainage and wall waterproofing.

Add Uw and SHGC or g-value as necessary to address thermal or solar performance requirements using our window thermal-metric guide. This data can be packaged with the remainder of the necessary information to purchase in a customized door and window quotation checklist served up as a commercial handoff.

Set a maintenance brief before handover

Coastal maintenance should be included in the project documents and not introduced as an after thought when the staining starts to fail. Ensure that there is safe access for cleaning and that there is a defined frequency for fresh-water rinse downs based on the level of exposure. List the approved cleaning products, define the frequency for inspection of the drainage system and for lubrication/adjustment of hardware. Document who carried out the work and how defects and failures are reported. A simple and realistic schedule will ensure that the finish is protected and will also provide the facilities team with a benchmark to identify failed seals, blocked outlets and loose hardware etc. early.

Frequently asked questions

Q: Is aluminum suitable near the sea?

A: No, the finish, hardware and fasteners, drainage, installation and even cleaning of the complete system must be considered. Alloy alone is not enough.

Q: How many salt-spray hours guarantee service life?

A: No single hour guarantees field life. Salt-spray tests are accelerated quality tests and do not simulate all possible corrosion scenarios that occur outdoors.

Q: What wind speed should I give the window factory?

A: Please provide the code or engineer derived design pressure for the particular facade zone of interest. Also provide building and unit information. This is in addition to the wind speed information above.

Q: Does a thicker frame guarantee a higher wind rating?

A: Section geometry, span, mullions, glass, hardware, fabrication and anchorage all work together. Use applicable test or engineering evidence to verify.

Q: Should coastal windows be thermal break?

A: Select a thermal frame based on the requirements of climate, comfort and energy, and select a corrosion system based on exposure requirements. Many projects require both.

FAQ

Q: What are the major heat benefits of thermal break aluminium windows compared to conventional aluminium?

A: Conventional aluminium is highly conductive, causing energy waste. A thermal break incorporates a strip of low-conductive polyamide, such as PA66, between the indoor and outdoor parts of the frames to break the thermal bridge and save heat.

Q: Why is it important to meet AS2047 standards when designing custom aluminium windows and doors in Australia?

A: The Australian Standard AS2047 sets out the minimum requirements for windows and glazed doors, which must be complied with by custom designs to resist wind pressure, be watertight, structurally sound, and have proper air sealing.

Q: What should be taken into account when selecting large glass aluminium doors for windy areas?

A: It is necessary to ensure structural resistance to wind loads, thickness of laminated or toughened Low-E glass, anti-corrosion surface protection like anodizing or marine-grade powder coating, security multi-point locks, and EPDM weather sealing in multiple channels.

Q: In what way is a PD door system different from conventional sliding/bi-fold doors?

A: The PD door system incorporates both sliding and swinging action within one sash. Firstly, the panel slides in a top-hung channel without floor rails, and subsequently swings in a manner similar to a conventional door, thereby providing optimum width of opening without occupying additional internal space.
