Windows for cold homes: checklist before deciding
Cold near windows can come from weak glass, conductive frames, air leakage, the shutter box or poor perimeter joints. The solution must address the complete opening.
Why a window feels cold
Surface temperature, air leakage and thermal bridges create discomfort near the window. North-facing rooms, shaded façades and exposed floors usually need extra care.
Profile and glass must work together
Low-emissivity glass helps retain indoor heat, but it must be combined with an insulating profile, effective seals and correct installation.
Shutter box and perimeter joints
The shutter box can be a significant weak point. The quote should state whether it is replaced, improved or sealed as part of the work.
Prioritise rooms by use
Bedrooms, living rooms and home-office areas often deliver the greatest comfort improvement when upgraded first.
Checklist before deciding
- Check orientation and room use.
- Ask for complete-window thermal performance.
- Include shutter box and perimeter sealing.
- Plan ventilation after improving airtightness.
Mistakes to avoid
- Choosing only by price.
- Forgetting the shutter box.
- Installing good glass with weak sealing.
- Using the same solution for every orientation.
What to include in the quote
To compare options properly, ask the quote to separate profile system, glass build-up, opening type, shutter or box, removal of old windows, perimeter sealing, finishes and installation schedule.
