Are triple pane windows worth the investment? Our HVAC experts reveal the pros, cons and the value they can add to your home
They're pricier, but the benefits are worth it


While it's highly likely you've heard of double glazing – window made with two panes of glass separated by an air gap for insulation – you may be less familiar with triple pane windows.
These instead feature three panes of glass with two air gaps, boosting the insulating properties, and helping to keep a home warm and cozy without contributing to energy bills.
But, as this option is more expensive at the outset than its more popular double glazed counterpart, are triple pane windows worth the investment? Here, HVAC experts share their thoughts on this small upgrade that can boost home value.
Are triple pane windows worth the investment?
In short, yes. Triple pane windows are a solid spend. Chad Kleis, vice president of business development for Window World says, 'Windows with triple pane glass are worth the investment. Even though they may typically be associated with use in colder climates due to the increased energy efficiency triple pane glass provides, there are additional benefits that make them suitable in any market.'
For example, key benefits include increased energy efficiency, helping you to save money at home by cutting energy bills for both heating and cooling. Kleis points out that triple pane windows also reduce the potential for condensation inside windows during winter, keeping your house warm without turning up the heat, and are one of the best ways to add value to your home.
'Fortunately, replacement windows offer one of the higher ROI's among all types of remodeling project that will at value to your home at around 65% of cost versus value,' he says.
That means, whatever the cost of the triple pane windows, you can count on it bumping up your property's value by around 65% of that.
Triple pane windows also reduce sound transmission, although it is possible to soundproof windows without replacing them, by sealing gaps and cracks with caulk, such as the Gorilla Waterproof Caulk & Seal 100% Silicone Sealant available at Amazon, and using soundproof window dressings, or soundproof window insulation kits.

This durable and easy-to-use window insulation shrink kit conveniently installs using just a standard hairdryer, and can simply be removed during warmer months without leaving behind any damage or residue.
What are the drawbacks of triple pane windows?
Perhaps the most obvious drawback with triple pane windows is the cost, but, as Hans Ingram, New York-based project manager at JSM Project Management, assures, 'Savings on energy costs over time will outweigh the initial up-front investment and actually save you money in the long run.'
The most considerable cost consideration is installation, as highlighted by Kyle Scott from EcoTech Windows & Doors. 'Additional glass and materials make triple-pane windows heavier, which may require additional support and could increase installation costs,' he says. 'You can increase the effectiveness of triple-pane windows by getting them professionally installed,' although calling in the pros will obviously be reflected in the cost. 'This guarantees proper sealing, which improves performance and prevents air infiltration, and can enhance the overall energy-efficiency.'
It is also worth considering where you live when pondering the upgrade, or you may risk diminished returns, adds Scott. 'In regions where temperatures do not drop below freezing, the benefits may not be as noticeable compared to other options,' he explains.
If you're not sold on spending, or want to hold off on taking the plunge, Robert Hamerly, principal and CEO at GreenSavers, recommends using window sealing film, such as the Duck Brand Rolled Insulation Film available at Walmart. 'These kits lessen the clarity of windows, but do a decent job to make a difference in leakiness,' and work well for DIY draft-proofing to insulate windows and weatherproof your windows, too.
FAQs
How often should windows be replaced?
While a costly upgrade, windows should be replaced every ten to twenty years, as even the best quality windows won't last forever. In particular, taking the time (and money) to do so is a smart home improvement for winter, keeping your house cozy and energy bills low.
Is it better to replace all windows at once?
Putting aside the issue of cost, if you're unsure whether to repair or replace your windows, it is recommended to replace your windows all at once, even if you're not renovating.
While only one or two windows may show signs of damage and degradation, it's likely that the others will soon follow, and it's therefore far easier and cost-effective to get them all done in one fell swoop.
'For homeowners thinking about replacing their windows, triple pane glass windows should be considered,' says Kleis. 'Think of it like this: home improvement project should be viewed as an investment, and each comes with a return on investment.'
