Budget Draught-Seal Length for Every Opening
Seal strips sell in packs; draughts live in millimetres. Convert each opening’s measured perimeter and sealing passes into the packs of seal the job actually consumes, before the third trip to the shop.

Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the draught seal packet: your opening | measured perimeter centimetres | sealing passes stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Seal strips run along the frame edge, so the perimeter that matters is the one the strip contacts. After: the draught seal packet shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Pack arithmetic on the measurements and pack size you supply. Not an energy audit, building-standard or ventilation assessment; confirm which gaps should be sealed with a qualified energy assessor or your building’s guidance before blocking any vent.

Boundary and sources
Pack arithmetic on the measurements and pack size you supply. Not an energy audit, building-standard or ventilation assessment; confirm which gaps should be sealed with a qualified energy assessor or your building’s guidance before blocking any vent.
- Method: Read the centimetres printed on the pack you plan to buy. Two hundred and fifty centimetres is a common retail pack; trade packs run longer.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.

Optional AI formatting, not calculation
For this draught seal packet, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a draught seal packet. Return plain rows only: opening | measured perimeter centimetres | sealing passes. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: opening | measured perimeter centimetres | sealing passes. No AI response is executed as code.
