Door Seals

Door seals are essential components used to create a barrier between a door and its frame, providing a variety of benefits ranging from weatherproofing and noise reduction to security and fire protection. These seals, often referred to as door seal strips or edging strips, are typically made of flexible materials like rubber, silicone, or plastic and available in various profiles and designs to suit different door types and performance requirements. These seals and edging strips, including door rubber seals and door gap seals, are fitted onto the edges of panels, doors, and windows, protecting against sharp metal or glass edges in Singapore.

In addition to sealing gaps, and particularly in the case of aluminium door seals, edging strips also serve a protective function in electrical installations by preventing cable and wire abrasion when routed through frames or grids.

Type of Door Seals and Edging Strips

Door seals and edging strips are available with different profiles, materials, and features to address a wide range of application needs. Some of the most common types include:

Profile Shapes: U-shaped, V-shaped, P-shaped, D-shaped, E-shaped, and bulb seals are popular choices, each designed to effectively seal specific gap sizes and configurations.
Materials: EPDM rubber, silicone rubber, PVC plastic, foam, and thermoplastic elastomers (TPE) are commonly used materials, each offering different levels of flexibility, durability, temperature resistance, and chemical resistance.
Door Bottom Seals: These specialised door seals are designed to close the gap at the bottom of doors, preventing drafts, dust, insects, and moisture from entering. They are available in various materials, including EPDM rubber, PVC, and brush strips.
Self-Adhesive Backing: Many door seals are available with a self-adhesive backing for easy and secure installation on clean, smooth surfaces.
Internal Support: Some door seal strips and seal profiles have added support with internal steel wire inserts or rigid plastic cores to enhance their structural integrity and prevent deformation over time.
Acoustic Seals: Designed to minimise sound transmission through doors, these seals are often used in recording studios, home theatres, and commercial buildings to prevent sound from leaking.
Fire-Rated Seals: These seals expand when exposed to high temperatures, creating a fire-resistant barrier that helps to contain the spread of flames and smoke.
Intumescent Seals: Used for fireproofing, intumescent materials expand when exposed to heat and fire creating a barrier against fire and smoke. Rubber door gaskets and PVC door seals are particularly popular for their durability, flexibility, and ability to conform to uneven surfaces.

Door Seal Strip Fixing Methods

Door seals and edging strips offer various fixing methods to suit different installation needs and surfaces.

Self-gripping, or push-on, door seals are designed with an internal gripping mechanism that securely attaches to the edge of a panel, door, or window without the need for additional adhesives or fasteners.

This method relies on the inherent tension and shape of the seal's profile to create a firm, long-lasting hold, and is particularly useful for applications where easy installation and removal are required, or when working with materials that are not suitable for adhesives.

For self-adhesive backed door seals, a pre-applied adhesive strip, protected by a release liner, simplifies installation. Simply peel away the liner to expose the adhesive and firmly press the seal onto a clean, smooth surface. This approach provides a swift and convenient mounting solution, though thorough surface preparation is essential for optimal adhesion.

How to Install a Door Gap Seal

Installing a door gap seal is a straightforward process that can significantly improve your home's energy efficiency and comfort. Here's a general guide:

Measure the Gap: Begin by accurately measuring the gap between the door and the frame along the entire length where you intend to install the seal.
Clean the Surface: Ensure the door frame and door edge are clean and dry. Remove any dirt, dust, or old adhesive residue.
Peel and Apply (for self-adhesive seals): If you're using a self-adhesive seal, peel away a small portion of the release liner to expose the adhesive. Carefully position the seal along the measured gap and press it firmly onto the surface. Gradually peel away the remaining liner as you continue to apply the seal.
Push-On Installation (for self-gripping seals): For self-gripping seals, align the seal with the edge of the door or frame and push it firmly into place. Ensure it's fully seated and secure.
Trim Excess (if needed): If any excess seal material extends beyond the door's edge, carefully trim it with a utility knife for a neat finish.

Brush Strips

A brush strip is a type of door seal that consists of a straight length of extruded aluminium or plastic, known as a carrier or holder. The plastic or aluminium carrier houses a length of filaments or bristles, usually made from black nylon, polypropylene, or other synthetic materials, in the form of a long brush.

What Does a Brush Strip Do?

Brush strips are typically attached to the bottom of a door and act as draught excluders to prevent drafts and keep in the heat. The brush also prevents dust, debris, insects, rodents, leaves, and litter from entering the threshold of a building or factory from outside. They are particularly effective on uneven surfaces, where traditional door seals may not make full contact.

Brush strips are also used in industrial applications to contain dust, fumes, and other airborne particles within a specific area, improving air quality and safety.

Industrial Applications of Door Seals & Edging Strips

Door seals and edging strips find versatile applications across diverse industrial environments, providing both protective and functional benefits:

Household Doors and Windows: Beyond residential use, these seals are crucial in manufacturing and prefabrication of doors and windows, ensuring quality and energy efficiency before installation.
Electrical Installations: In industrial electrical setups, edging strips protect cables and wiring from abrasion and damage when passing through panels or enclosures.
Shopfitting: Retail and commercial spaces utilise door seals and edging strips for both aesthetic and functional purposes. They create clean, finished edges on displays and fixtures, while also providing protection against wear and tear in high-traffic areas.
Joinery and Fabrication: In joinery and fabrication workshops, these strips are used to create precise seals and edges on custom-built furniture, cabinets, and other fabricated items.
Workshops and Factory Floors: Within workshops and factory environments, edging strips protect workers from sharp metal edges on machinery and equipment. They also help to create sealed environments around sensitive equipment, preventing dust and debris ingress.
Automotive Production Lines: In automotive manufacturing, door seals and edging strips are essential for creating airtight and weatherproof seals on vehicle doors, windows, and other openings.

Choosing the Right Door Seal

Here’s what you need to consider before you choose a seal or gasket for your door:

Gap Size: Accurately measure the gap you need to seal to ensure you select a door seal with the appropriate profile and dimensions.
Door Material: Consider the material of your door (wood, metal, fiberglass, etc.) and choose a seal that is compatible with that material.
Surface Condition: Ensure that the surface where you will be installing the seal is clean, dry, and smooth. If your surface is uneven, flexible materials like a rubber door seal or PVC door seal will be more suitable than rigid aluminium door seals.
Durability: Choose a seal made from durable materials that can withstand the wear and tear of daily use.
Environmental Conditions: Consider the environmental conditions the door seal will be exposed to, such as temperature, humidity, and UV exposure.
Ease of Installation: Consider the ease of installation and choose a fixing method that suits your skills and available tools.
