Why is proper sealing of windows and doors essential?
Poor sealing around windows and doors can have surprisingly significant consequences. Not only for your energy bill, but also for comfort and durability.
Less heat loss and lower energy costs
Poorly installed or insufficiently sealed windows can cause up to 30% heat loss. A correct, airtight connection limits this loss and reduces the energy demand for heating and cooling. This can make a significant difference on the energy bill each year.
No draught or moisture problems
Draughts along windows or doors often indicate air leaks in the connection joints. Those same openings can also allow moisture to enter. Moisture infiltration increases the risk of mould formation and can, over time, cause damage to walls, plasterwork or joinery. Proper sealing prevents these problems.
Better sound insulation
Many people think that sound mainly enters through the glass. In reality, poorly finished connections are often the weak link. By sealing joints correctly, disturbing outdoor noise is significantly reduced. This noticeably increases living and working comfort.
Longer lifespan of windows and doors
Durable sealing protects joinery against moisture, temperature fluctuations and external influences. As a result, windows and doors last longer and their performance is maintained over the long term.
How does DL Chemicals achieve this?
Good sealing does not consist of a single product, but of a well-considered combination of solutions. That is why DL Chemicals works with a system approach in which different sealing products together ensure:
- a weather-resistant exterior
- an insulating middle zone
- an airtight interior
This creates an energy-efficient and durable connection that meets current building requirements.
