What Are You Looking For?
Thermal break aluminum doors are known for their durability, energy efficiency, and sleek design. However, even the best doors can lose their insulating properties if not paired with the right sealing strips. High-quality seals prevent drafts, reduce noise, and improve thermal performance—making them essential for modern homes and buildings.
Sealing strips for aluminum alloy doors are available in a wide range of profiles, each designed to fit specific types of gaps and provide optimal sealing. Some of the most common profiles include:
• O-Type Sealing Strips: These are circular in cross-section and are highly flexible. They are ideal for gaps that require a snug fit without excessive compression. O-type strips are often used in areas where the door frame and the door itself have a relatively smooth and even contact surface.
• D-Type Sealing Strips: With a semi-circular profile, D-type strips are perfect for slightly larger gaps. They offer excellent sealing properties and are commonly used in the middle or side frames of doors to prevent air leakage.
• L-Type Sealing Strips: These strips have an L-shaped profile, making them suitable for corners and edges. Their design allows them to fit snugly into the frame, providing a tight seal against both air and water ingress.
• V-Type Sealing Strips: V-shaped strips are designed to fit into narrow gaps and provide a strong seal. They are often used in the bottom or top edges of doors, where the pressure from closing the door helps to create a tight seal.
Customizable Sizes for a Perfect Fit
The beauty of sealing strips lies in their ability to be customized to fit the exact dimensions of the gaps in aluminum alloy doors. Whether the gap is 1mm or 5mm wide, there is a sealing strip that can be tailored to fit perfectly. For instance, some manufacturers offer strips with adjustable compression levels, allowing installers to fine-tune the fit to ensure no air or water can pass through. This customization is crucial for achieving the best possible seal, especially in doors that are exposed to harsh weather conditions.
Our sealing strips come with self-adhesive backing or groove-fit designs for quick installation. Once applied, they maintain their shape for years without cracking or shrinking.
Soundproofing and DustproofingIn addition to their thermal benefits, sealing strips also provide excellent soundproofing and dustproofing. The tight seal they create helps to block out external noise, making the interior of a building quieter and more peaceful. At the same time, they prevent dust and other airborne particles from entering through gaps in the door, contributing to a cleaner and healthier indoor environment.
