burletes

Burletes are weatherstripping products used to seal gaps around doors and windows, preventing drafts and air leakage. The term is common in Spanish-speaking contexts, but the concept corresponds to what English speakers call weatherstripping, door seals, or gaskets. Burletes can refer to a range of profiles and materials designed to close the space between moving parts and frames.

Typical forms include door sweeps that seal at the bottom of a door, window weatherstrips along sashes or frames, adhesive foam tapes, and V- or bulb-shaped profiles. Materials vary widely and may include EPDM rubber, vinyl, silicone, or polyurethane foam. Some burletes are self-adhesive, while others are attached with fasteners or mechanical fittings.

Purposes and benefits include reducing heat loss or gain, improving comfort by eliminating drafts, and lowering energy costs. Additional advantages can include quieter operation, reduced dust ingress, and better moisture control. The effectiveness of a burlete depends on proper fit, material choice for the environment, and maintenance.

Installation and maintenance considerations: measure the length of the gap and cut profiles to size, ensuring smooth, even contact with the frame or sill. Clean mounting surfaces and follow adhesive instructions for self-adhesive products. For movable components, verify that the seal does not impede operation. Replace worn or cracked profiles as compression set or damage occurs to maintain effectiveness.
