Are twin blocks suitable for a private house?
Krympress reports:
Twin blocks — A great solution for private housing construction, but with important nuances of application. Consider all aspects of their use.
1. Key advantages for private construction
Technical characteristics:
✔ D400-D600 density-optimal balance of strength and thermal insulation
✔ Thermal conductivity 0.09-0.14 W/(m · ° C)-3 times warmer than brick
✔ Frost resistance F50-F100-suitable for most regions of Russia
✔ exact geometry (± 1 mm)-allows you to put on a thin seam (2-3 mm)
Operational advantages:
- Speed of construction (1 m² of wall-20-30 minutes)
- Lightness of processing (sawn with manual hacksaw)
- Vapor permeability (walls «breathe»)
- Non -combustibility (fire safety class NG)
2. Features of application
For what designs are suitable:
✅ Carrying walls (up to 3 floors at D500-D600)
✅ Internal partitions (D300-D400)
✅ insulation (in combination with other materials)
Restrictions:
❌ basement floors (waterproofing is required)
❌ foundations (insufficient compression strength)
❌ chimneys (temperature resistance up to 400 ° C)
3. Comparison with other materials
Twin-block
- Masonry speed: 1 m²/30 min
- Thermal conductivity: 0.10
- Weight: 240 kg
Aerated concrete
- Masonry speed: 1 m²/40 min
- Thermal conductivity: 0.12
- Weight: 280 kg
Ceramic block
- Masonry speed: 1 m²/60 min
- Thermal conductivity: 0.18
- Weight: 320 kg
Brick
- Masonry speed: 1 m²/120 min
- Thermal conductivity: 0.56
- Weight: 480 kg
4. Technological nuances of construction
✅ Mandatory requirements:
- Foundation: monolithic slab or dressing tape
- Reinforcement: every 4th row + openings zones
- Armopias: reinforced concrete under ceilings
- Finishing: plaster or ventilated facade
❌ Proceeded actions:
- Using cement mortar instead of glue
- Lack of waterproofing of the first row
- Masonry at temperatures below +5 ° C without additives
- Leaving unprotected masonry for the winter
5. Economic benefit
For the house 100 m² (one floor):
- Savings on the foundation: 30-40% (due to lightness)
- Reducing heating costs: up to 50%
- Construction time: 2 times faster than brick
- Payback: additional costs for glue and reinforcement are compensated for 3-5 years by saving on heating.
6. Recommendations for choice
For load-bearing walls: D500-D600 300-400 mm thick
For partitions: D300-D350 100-200 mm thick
For attic: D400 with compulsory armored carrier
Important: buy blocks of only 1 accuracy category — they provide thin -haired masonry.
7. Typical errors of builders
❌ Savings in an armored carrier
❌ Using a metal mesh instead of fiberglass reinforcement
❌ Lack of deformation seams in long walls (> 6 m)
❌ improper storage (should be on pallets, under the film)
Conclusion: Twin blocks-an excellent choice for a private house subject to technology. They provide:
✔️ Building construction
✔️ Taping walls
✔️ Dolivenia of 50+ years
✔️ Sorrow on the entire operation cycle
For regions with a harsh climate, additional insulation (mineral wool is 50-100 mm) is recommended. In the middle strip of Russia, walls of twin blocks with a thickness of 400 mm do not require additional insulation.
