Aluminium vs Wooden Windows in Hope Pastures: Heat, Rot and Upkeep

Pick aluminium if you want windows you mostly just wash. Pick wood if you like painted timber and you'll actually keep it painted, because wooden frames can last decades with consistent upkeep, and that upkeep is what holds off rot. In an older Hope Pastures house, check the timber you already have for termites before you decide. Whichever frame you pick, Malcolm's Hardware on Slipe Road in Cross Roads has paint and fasteners departments for the work around it.

Key Takeaways

• Renewal by Andersen, a US window maker, says aluminium window frames never need painting or staining, only periodic cleaning.
• The same window maker says wooden frames can last decades with consistent upkeep, but can be more prone to rot and termite damage.
• Natural Resources Canada says aluminium conducts heat more than non-metals, but a window's overall energy efficiency depends more on the design of the whole window.
• The California Department of Food and Agriculture lists Jamaica among the places the wood-feeding West Indian drywood termite is found, so it's a risk for wooden frames and not for aluminium ones.
• Renewal by Andersen also says aluminium isn't particularly resistant to salt air, can corrode over time and may not be the best choice for coastal areas.

How do aluminium and wooden windows compare?

Aluminium wins on upkeep and on termites. Wood wins on keeping heat out of the frame itself, and it's easier to patch. Both can last a long time. With wood, that takes consistent upkeep: sealing, patching and painting.

Which one lasts longer?

If nobody is going to look after the windows, aluminium asks less of you. Wooden frames can last decades too, but only with regular care.

Renewal by Andersen's guide to window frame materials, published in July 2026 and updated in September 2026, says aluminium frames are structurally long lasting, though seals and hardware may need attention over time. It says aluminium forms a thin oxide coating in air that helps protect it. The same guide says wood frames can last decades with consistent upkeep, and that wooden windows can be more prone to rot and termite damage.

One thing to know about that source: Renewal by Andersen sells composite windows of its own, so read it as a window maker's view rather than a neutral one.

Damage is where wood has the edge. The guide says a scratched or dented aluminium frame often needs full-frame replacement, with no quick fix. A wooden frame can be patched, sealed and repainted.

Do aluminium windows make a room hotter?

The frame lets more heat through than a wooden one, but it's only part of the picture. The design of the whole window, glass included, counts for more.

Natural Resources Canada's guide to upgrading windows and exterior doors, last modified in January 2025, says aluminium conducts heat more than non-metals, but that a window's overall energy efficiency depends more on the actual design of the product. Renewal by Andersen says aluminium without a thermal break can create a direct path for heat transfer, and suggests thermally broken frames, which have an insulated barrier inside. It also calls the frame just one part of a window's energy performance, along with the glass type, the number of panes and the quality of installation.

Kingston's climate is hot and humid. If a bedroom bakes in the afternoon, ask your window supplier about the glass and about shading that window before you pay extra for a frame on heat grounds alone.

What about termites?

They're the strongest reason to think twice about new wooden frames in an older house. The California Department of Food and Agriculture's 2025 profile of the West Indian drywood termite lists Jamaica among the places it's found. It describes the termite as a wood-feeding pest that is generally restricted to buildings and furniture. It also says the termite can cause severe damage to wooden structures, that old buildings are especially vulnerable, and that the swarming termites leave their wings behind.

So if you find small discarded wings on a window sill, or the house has had termites before, have a pest control company look at the frames and the timber around them. New wood fitted next to an active colony is new food.

How much upkeep does each one need?

Aluminium needs washing. Wood needs painting, plus a look at the sills and joints every so often.

Renewal by Andersen's guide says aluminium never needs painting or staining, just periodic cleaning, and that wood needs regular upkeep to prevent rot, warping and chipped paint. It also says aluminium isn't particularly resistant to salt air and can corrode over time, and that it may not be the best choice for coastal areas.

A frame tucked under a verandah roof doesn't get rinsed by rain, so give it a wipe more often than one facing open sky. For wood, the paint is the protection. Keep it unbroken on the outside face and on the sill, and fix cracks before the rainy season rather than after. Our guide to choosing exterior paint for a Kingston home covers how sun, salt air and the rainy season treat outside paint.

What drives the cost of each?

Price each option on the same openings, installed and finished, and then add what it takes to look after it. The frame on its own isn't the whole bill.

When you get quotes, ask each supplier exactly what's included: the frames, the glass, fitting, making good the wall around the opening, and refitting any grilles or burglar bars. For wood, add the primer and paint at the start and the repainting over the years. For aluminium, ask whether the frames have a thermal break, and what finish they come in, because you can't repaint it later to change the look.

If you're changing windows partly for security, sort out the grilles in the same job. Our comparison of grilles, burglar bars and roll-down shutters goes through the options, and our hurricane season checklist covers boarding up windows before a storm.

Which should I choose?

Start from how you live with the house, not from the brochure.

Checking the windows in a Hope Pastures house

Hope Pastures started life as a planned housing scheme. A 2022 Supreme Court of Jamaica judgment refers to the approval of the Hope Housing Scheme by the House of Representatives in April 1961 and the Legislative Council in May 1961, and says the scheme is made up of 228 properties. Jamaica College's history of its surrounding community says Hope Pastures was established in 1962.

So the scheme is more than sixty years old. If your house still has wooden frames, check them before anyone quotes you for a full replacement. Natural Resources Canada's guide suggests checking each window for rot, mould or staining, and for the condition of the glass, putty and paint. In practice:

1. Press the sill and the bottom of each sash with a screwdriver tip. Firm wood is fine. Soft wood that the tip sinks into is rot.
2. Look along the sills and in the window tracks for discarded termite wings.
3. Check the paint on the outside face. Bare or cracked patches are where water gets in.
4. Look at how any grilles are fixed, so you know what has to come off if the frames are changed.

If the soft spots are few and the rest is sound, repairing and repainting can buy the frames years. Our guide to deciding between repair and replacement walks through that call. Our Hope Pastures page has more for customers coming from that side of Saint Andrew.
