Windows
For most jobs, the choice comes down to frame material, glazing spec and how much room you’ve got to work with. uPVC windows usually keep cost and maintenance down. Aluminium suits slimmer sightlines and a firmer feel. Timber still makes sense where the job needs a more traditional finish. Double glazed windows cover most replacement work. Triple glazed windows only earn their keep where the spec justifies the extra cost and weight.

For the Trade
You narrow windows by the spec first, then by what the opening and the job will actually take. For standard replacement work, uPVC windows usually stay on the table because they keep the job straightforward. If the brief calls for a slimmer frame or a firmer finish, aluminium windows are the next conversation. Timber still comes up where the property or planning pushes you that way, but it changes the maintenance side. Double glazed windows suit most everyday work. Triple glazed windows only make sense when the performance target justifies the extra weight and cost.
Popular Window Formats
Most jobs come down to the spec first. If the brief is lower heat loss, look at u value windows and energy efficient windows. For ordinary replacement work, double glazed windows usually cover it without pushing the spec too far.
Triple glazed windows suit jobs where performance matters more than cost or weight. The trade-off is handling and price.
Trade windows work when you want a straightforward supply option and a quicker fit. Replacement windows make more sense when you are matching an existing opening and want fewer surprises.
If you are comparing the full range, start at Windows & Window Fittings and narrow it from there.
Key Differences When Choosing
Material is where you narrow it down. aluminium windows usually suit jobs where you want a stiffer frame and slimmer sections, but you feel that in handling on site, and the price usually sits higher.
upvc windows are lighter to move and easier on straightforward replacements. They usually keep the job more economical, though you do not get the same rigid feel.
timber windows still get picked where the spec or the property calls for it. They bring more upkeep and need more care on delivery and fitting.
If you are also sorting the finish around the opening, Blinds and Glazing Sheets are the next decisions that usually change what you buy.
Next Decisions After Choosing
Once the windows are chosen, the next call is usually what finishes the opening and what sits around it. If you need light control or privacy, blinds are the usual follow-on. If the opening still needs making good or protecting during a wider refit, glazing sheets are the temporary fix.
That is where the job splits. One side is the finished result. The other is keeping the opening usable while the rest of the work carries on. Get that wrong and you end up back at the same opening twice.
