What Majority Is Needed for Insulation?
Although external wall insulation is a change to common areas, it is separately regulated and eased under the statute. Under Article 42 of the Condominium Law, thermal insulation may be carried out at the request of any owner on a resolution passed by a majority of owners by number and by land share.
In other words, the four-fifths consent required for works such as repainting the façade does not apply to thermal insulation. This distinction is often confused in practice and needlessly blocks the process.
If the façade colour will also change, stating the colour expressly in the resolution and presenting a visual sample reduces objections.
Preparing the Request
- The building's existing insulation status and any energy performance certificate
- Quotations from at least three contractors (unit rate per square metre and total)
- The type and thickness of the material to be used
- Scaffolding, duration and health and safety measures
- Whether municipal permission or notification is required
- An estimate of the fuel savings expected after insulation
The savings estimate is the most persuasive element. Showing in figures how many years the investment takes to pay back markedly increases approval rates at the meeting.

TO THE MANAGEMENT / CHAIR OF THE GENERAL ASSEMBLY
Subject: Our request for thermal insulation to be applied to the building's external walls.
We, the owners whose names, unit numbers and signatures appear below, request that thermal insulation be applied to the building's external walls.
GROUNDS
1. Our building was constructed in ……………… and has no thermal insulation on its external walls. Heating costs are consequently high and damp and mould are appearing on external walls.
2. The attached quotation from ……………………… states a total cost of ………… TRY (…… m² × ………… TRY). The contractor estimates savings of approximately …… percent on heating costs after the work.
3. Under Article 42 of the Condominium Law, thermal insulation may be carried out on a resolution passed by a majority of owners by number and by land share. A four-fifths majority is not required.
OUR REQUEST
a) That the matter be placed on the agenda of the next general assembly meeting,
b) That quotations be obtained from at least three contractors for comparison,
c) That the material type, thickness and façade colour be stated expressly in the resolution,
d) That health and safety and scaffolding terms be set out in the contract,
e) That the cost allocation be resolved in accordance with the management plan.
We submit the above for your consideration. …/…/20…

Filling Guide
State the material type and thickness in the resolution. Simply resolving "to carry out insulation" leads to thinner and cheaper material being used.
Specify the façade colour by colour code. Colour is the issue that generates the most argument during the works.
Include the warranty period. Blistering and cracking in insulation systems appear in the early years.
During the Works
Safety risks increase while scaffolding is up; access must be managed and residents informed. Periods during which windows should stay closed must be announced in advance.
On completion, the façade and details should be inspected together and any defects recorded. Withholding part of the payment until acceptance protects the management.
Common Mistakes
- Requiring a four-fifths majority: a dual majority is sufficient for thermal insulation.
- Not specifying thickness: thin material will not deliver the expected savings.
- Deferring the colour decision: disputes arise during application.
- Deciding on a single quotation: price differences can be very large.
- No warranty: leaves no recourse if blistering or cracking occurs.
