FAQs: Mica vs Timber Frame

Q1: What is mica and why is it a problem in Donegal?
Mica is a mineral found in defective concrete blocks. When it absorbs water, it causes the blocks to weaken, crack, and crumble. Thousands of homes in Donegal have been affected, making them unsafe.

Q2. Can pyrite also cause problems like mica?
Yes. Pyrite is another mineral that can cause structural issues in blocks and concrete. Whether it’s mica, pyrite, or another defect, blockwork carries hidden risks that timber frame construction avoids.

Q3. How does timber frame avoid the risk of mica?
Timber frame homes don’t use concrete blocks in their main structure. Closed-panel timber frames with cement board are completely free from mica and pyrite.

Q4. Does a timber frame house look different from a block house?
No. With cement board on the outside, a timber frame home can be plastered or rendered just like a block-built home. The finished look is the same.

Q5. Is timber frame stronger or weaker than blockwork?
Modern timber frame is just as strong as blockwork — and in many cases performs better. It is precision-engineered, energy efficient, and proven to last in Ireland’s climate.

Q6. Is timber frame cheaper than blockwork?
Timber frame often works out cheaper because of faster build times, lower labour costs, and long-term energy savings. It’s also a safer investment since it avoids mica or pyrite risks.

Q7. Can I rebuild my mica-affected home in Donegal with timber frame?
Yes. Many homeowners in Donegal are choosing timber frame with cement board as a reliable, mica-free alternative when rebuilding.
