Can I measure ceiling and roof areas for bulk insulation?

Yes. Measure ceiling and roof areas straight from the plan to total the bulk insulation quantity, rather than estimating from room dimensions.

Can I measure wall insulation with openings deducted?

Measure external wall areas and subtract the openings to get the net area for wall insulation, so your batt and roll counts are accurate.

Will it help me order the right amount?

Because you measure real areas and convert them to batts and rolls, you avoid the over- and under-ordering that comes from rough guesses on complex plans.

How do I work out batt quantities from a measured area?

Measure the wall or ceiling area in square metres, then divide by the coverage of your batt pack for that R-value to get the number of packs. MetreMate totals the areas as you go, so the pack count is a quick step from there.

Can I keep ceiling, wall, and underfloor areas separate?

Yes. Put each element on its own layer as you measure, so ceiling, external wall, and underfloor areas total on their own. That lets you order the right product and R-value for each without mixing the quantities.

How accurate is measuring insulation areas off the plan?

As accurate as the drawing. With the scale set and openings deducted, your net areas match the plan, so your batt and roll counts are reliable rather than an allowance off rough room sizes.

MetreMate for Insulation Installers

Why insulation installers choose MetreMate

Insulation installers use MetreMate to measure wall, ceiling, and underfloor areas from building plans and turn them into batts and rolls with less wastage. Use the Area tool for insulation quantities and sarking coverage, or the Measure tool for metres of sarking roll. It runs in your browser, so you can quote from the plan without estimating off rough room sizes.
