Discreet Ventilation with Hidden Trickle Vents

Proper ventilation is essential for maintaining a healthy indoor environment, preventing condensation, and protecting your home from damp issues. At Surrey Sash, we offer hidden trickle vents in our sash windows—providing effective airflow without compromising on aesthetics.

Why Choose Hidden Trickle Vents?

🔹 Subtle Design – Integrated discreetly into the frame, ensuring they don’t disrupt the classic sash window look.

🔹 Improved Airflow – Helps reduce moisture buildup and improve indoor air quality without needing to open the window.

🔹 Building Regulations Compliance – Meets ventilation requirements for new-builds and renovations without affecting heritage aesthetics.

🔹 Energy Efficiency – Allows controlled airflow without significant heat loss, keeping your home comfortable year-round.

Our hidden trickle vents are designed to blend seamlessly with your sash windows, ensuring you get all the benefits of modern ventilation while preserving the traditional beauty of your property.

A Window That Performs as Beautifully as It Looks

Our timber sash windows don’t just enhance your home’s appearance—they also boost thermal performance, security, and acoustic insulation. With advanced double glazing, high-security locking systems, and precision-engineered timber frames, you can enjoy modern comfort without compromising on style.

✅ U-values as low as 0.8 W/m²K for improved energy efficiency
✅ PAS24 compliant options for enhanced security
✅ Low-maintenance coatings for long-lasting durability

Colour options for your windows

At Surrey Sash LTD, all our windows are finished in RAL 9016 "Traffic White" as standard, a timeless and versatile shade that complements any property. However, we offer complete flexibility with our colour options. Whether you’re looking for a bold statement or a subtle heritage tone, we can match any colour to suit your style and project requirements.

For added personalisation, we also offer dual-colour finishes, allowing you to choose different colours for the interior and exterior of your windows. This means you can have a classic or vibrant exterior while keeping a colour scheme indoors that complements your interior décor.
