Let’s talk Trickle Vents.
Under the current building regulations, trickle vents are now standard and mandatory on almost all new and replacement windows.
🤔 What are trickle vents?
They are small, controllable slots built into the top of your window frames that allow fresh air to circulate naturally, even when your windows are securely locked.
đź’¨ Why are they required?
Modern windows are incredibly airtight (which is great for your heating bills!). However, without proper ventilation, everyday activities like cooking, showering, and drying clothes can lead to trapped moisture, condensation, and nasty mold growth. Trickle vents keep your indoor air fresh and healthy without creating a freezing draft.
🛠️ Do I really have to have them?
In short: yes. If your old windows had them, the new ones must have them. If your old windows didn’t have them, the new ones still need them to comply with current ventilation standards.
Don't worry—modern trickle vents are sleek, color-matched to your frames, and completely adjustable so you can open or close them whenever you like.
Looking to upgrade your ventilation - I can install trickle vents into your current windows without the need for you to spend out on brand new windows.
