Guides for homeowners

SEAI guide

External doors can be a major comfort weak point in older homes — draughts, poor seals and thin construction lose heat quickly.

Door grant in context

SEAI lists support for efficient external doors. Treat doors as part of a wider retrofit plan: external wall insulation improves walls, but a poor door still leaks heat.

Detailing with EWI

When wrapping the house, door reveals and thresholds need careful planning. Mention door upgrades during survey if you want them coordinated with the wrap finish.
