When comparing window quotes it's easy to focus on price alone and overlook what's actually included in it. Yet what one supplier adds as an option can be standard with another — and the difference can be noticeable. In this article we explain what's included in the price of our windows and why it's worth paying attention to when choosing a contractor.

A warm-edge spacer as standard

A warm-edge spacer is part of the glazing unit that replaces the traditional aluminium spacer bar with a version of lower thermal conductivity. The result? A smaller thermal bridge at the edge of the glass, warmer glass by the frame and less risk of water vapour condensing at the edges of the window in winter. With us the warm-edge spacer is standard — not an extra.

Why it matters

Not every supplier includes a warm-edge spacer in the price. With some British manufacturers in particular it can be a chargeable extra. Comparing the bare figures from two quotes, it's easy to miss — yet it's a real difference in quality and comfort. That's why it's always worth asking exactly what the price includes.

External sills included

Another element that's standard with us is external sills. They're a practical finishing that protects the join between the window and the wall and carries off rainwater. Charged separately they can push up the bill — with us they're part of the offer, so they won't surprise you later on the invoice.

What else is worth checking in a quote

When comparing window quotes, ask not only about price but about scope: the type of glazing, the warm-edge spacer, sills, finishing, warranty and the extent of installation. An honest quote states clearly what's in the price and what's extra. We stand for transparency — we'd rather you knew exactly what you're paying for.

Frequently asked questions

What is a warm-edge spacer and what's it for?

It's a part of the glazing unit with low thermal conductivity. It reduces the thermal bridge and condensation at the edge of the glass. With us it's standard.

Are external sills included in the price?

Yes, with us external sills are standard, so they won't appear as a surprise on the invoice.

Why do quotes differ so much?

Because they differ in scope. One supplier charges for what another includes. It's always worth comparing exactly what the figure covers.
