Versatile compatibility and purpose Designed for sliding doors and windows, this acoustic foam sealing strip fills gaps to reduce air transfer and heat loss. Use it where sealing, insulation, and noise reduction are needed without modifying existing frames. Why you need it — practical benefits Improves thermal insulation and energy efficiency by closing gaps that let warm or cool air escape, helping reduce heating and cooling loss. Blocks drafts and dust with density foam, keeping indoor temperatures steadier and air cleaner in all seasons and in harsh weather. Reduces noise transmission through door and window gaps, creating a quieter, more comfortable living space in busy or noisy locations. Key attributes Material: density acoustic foam engineered to resist drafts, dust, and sound transmission. Form: flexible strip that conforms to irregular edges and narrow gaps common on sliding doors and windows. Adhesion and handling: strong, preapplied adhesive backing that enables quick, tool application; strip is easy to trim to length for precise fit. Performance: balances windproofing, dust blocking, and sound insulation for yearround use without permanent alterations. How it solves common problems Drafts and cold spots: seals gaps that cause uncomfortable drafts and uneven room temperatures. Noise leakage: soft, dense foam reduces rattling and dampens outside noise that comes through frame gaps. Dust and pests: closes entry points where dust and small insects can enter, improving indoor cleanliness. Typical applications Sliding patio door: seal the vertical edge and bottom gap to reduce heat loss, stop drafts, and cut down outside noise from a busy yard or street. Bedroom or home office window: apply around window sashes to improve quietness and comfort for sleep or concentration.
