Profiled timber is a high-tech building material that is made without the use of glue or other chemicals. This material is both environmentally friendly and breathable. Furthermore, the wood is properly prepared, resulting in an outstanding geometry that substantially simplifies the assembly of the pieces – Air Sealing .
Because the elements of profiled lumber are easily and precisely joined, some people believe that structures made of it should not be insulated further. Let’s take a look to determine if this is true.
Is It Necessary For Me To Seal Buildings Built Of Profiled Wood?
Any building made of wood will shrink over time, and profiled wood is no exception. Yes, this material has been tuned to the proper parameters, and the blocks fit together snugly, but a small gap at the junction of the crowns will suffice to allow heat to escape the structure.
If no action is taken, a small gap will widen as a result of weather phenomena and temperature changes, and heat loss will become more visible. The natural conclusion that profiled timber buildings must be sealed.
Two stages to the process of sealing a structure from a bar:
- A mezhventsovy insulation installed during the log home installation (sometimes from jute, flax, moss, etc.).
- The cracks fixed with caulking or newer sealants after they have shrunk.
How to Pick the Best Sealant
Acrylic sealants are the best option for timber structures. Supporters of caulking as the most environmentally responsible way of home insulation will complain, but it’s important to remember that acrylic compounds are completely safe for the environment and humans, and emit no hazardous elements.
The following are the key benefits of acrylic sealants:
- Permeability of water vapour – wood breathes but does not absorb moisture.
- Prevents insects from destroying natural insulation.
- When the wood shrinks, they do not distort.
- Resistant to the elements. Snow, rain, wind, temperature drops, and other elements have little effect on sealants.
- They have strong adhesion and thixotropy, ensuring that the composition fills all gaps.
- They have poor thermal conductivity, which means the house will not heat up.
- Simple and straightforward to use.
- Colours are different.
The durability of acrylic sealants is one of its key advantages. If you use it properly and in accordance with the technology, your home will be safe for the next 20-25 years.
What is the best way to seal
After the initial shrinking of the home passed – 1-2 years after construction – the sealant utilised for insulation. Begin by doing some preliminary work:
They remove dirt and dust from the surface. You able to sand the unclean areas around the gaps a little in some circumstances of Air Sealing .
Construction tape used to seal the wood, allowing only access to the insulated gaps, cracks, and seams to a Air Sealing .
The sealant applied in dry, warm conditions. In any event, the temperature not go below +8 degrees Celsius. The composition do not applied on damp or frozen wood. Create settings where the treated surface not to exposed to precipitation or direct sunshine.
The procedure is straightforward:
A construction gun used to fill small gaps with sealant. A spatula used to scrape away any extra composition.
Use a sealing string for additional insulation if the seams are broader than 5 mm. In the same way, a sealant applied to the cord.
When sealing, keep an eye on the consistency of the sealant layer thickness (this is easy to check with a match or a toothpick). If bubbles form in the seam, they penetrated and the sealant re-walked.
Because the acrylic composition’s principal film appears 15–20 minutes after application, you’ll need to wander around with a spatula during this time to level the seam. The sealant takes at least a day to dry completely. Precipitation and direct sunshine should not fall on the sealing areas during this time.
