Draught Proofing

Choose the Right Draught Proofing for Every Opening

There are various types of draught-proofing materials, each suitable for specific gaps and situations. Functionality and lifespan depend strongly on the right choice and application.

Draught Seals: Sealing Gaps in Frames

Draught seals are self-adhesive strips placed in the rebate of windows and doors. They are available in different profiles, each designed to seal a certain width of gap. The correct profile ensures optimal closure and prevents the seal from hindering the function of the door or window.

Draught Excluders: For Doors and Larger Openings

While draught seals are mainly for frames, draught excluders are a solution for the bottom of doors and other larger openings. They are more robust and come in various types:

• Draught excluders with brush: Often made of aluminium or plastic with soft bristles. They are mounted at the bottom of the door and sweep over the floor or threshold. Suitable for interior doors and keep out dust and drafts without damaging the floor.
• Draught excluders with rubber lip: These variants have a flexible rubber lip that fits tightly against the threshold or floor when the door is closed. Widely applicable for both interior and exterior doors, they provide an effective seal against moisture and cold.
• Automatic drop seals: Built-in mechanisms in the door that lower a sealing profile when the door is closed. This offers a discrete and effective solution for sealing the gap under the door, with no visible elements when the door is open. Suitable for soundproofing and smoke tightness.

Additional Solutions Against Draught

Besides doors and windows, there are more places where draught is unwanted. Specific products offer solutions:

• Letterbox brushes: A simple yet effective solution to block cold air entering through the letterbox opening. These are mounted on the inside of the door.
• Draught sausages (door snakes): A temporary or additional solution for large gaps under interior doors. This sausage, often filled with foam, is slid under the door to block drafts. Suitable for smooth floors.

Proper Installation of Draught Proofing

The installation of draught-proofing materials is often a job that an experienced DIYer can carry out. Some key points help ensure a good result:

• Determine location: Locate draughty spots by running a flame (candle) or wet hand along the edges of windows and doors. Also check ventilation grilles that do not close properly or wall penetrations.
• Preparation: A clean, grease-free and dry surface is important for the adhesion of self-adhesive seals and strips.
• Measure and cut accurately: Measure the required length carefully and cut the material to size. For brush or rubber strips, saw on the correct side to keep the functional parts intact.
• Proper fixation: Follow the manufacturer's instructions. For self-adhesive products: remove the protective film and press firmly. For strips that are screwed or nailed: ensure a stable fixation.

Sustainability and Savings from Draught Proofing

Draught proofing is an investment that pays for itself. By sealing gaps and cracks, heating demand is reduced, leading to lower energy consumption and noticeable savings on heating costs. It contributes to a more comfortable and quieter home. Depending on the extent of gaps to be sealed and the type of house, annual energy savings can increase significantly. Products vary in lifespan; regular checks and replacement if needed ensure lasting benefit.
