Timloc lap vents are designed to improve ventilation by separating lap joints in roofing felt or membrane construction, enhancing air circulation, and preventing condensation buildup in cold roof voids.
Proper ventilation is crucial for maintaining a healthy and durable roof, especially in existing roof spaces where additional loft insulation may restrict airflow.
These innovative felt lap vents are effective for managing moisture in roof spaces; protecting your home, preventing loft condensation and ensuring your roof remains in optimal condition throughout the year.
Why Choose Timloc Lap Vents?
The underlay lap ventilator by Timloc is an effective roof ventilation system and the ideal solution to loft condensation.
Suitable for new builds and as a remedial solution for combating condensation in cold roof voids, vents can be fitted retrospectively after increased loft insulation.
Key Features & Benefits
Efficient Ventilation
Timloc lap vents offer an impressive additional 3,000mm² of free vent area, facilitating optimal airflow in your roof space.
Adequate roof ventilation prevents loft condensation and safeguards against potential problems such as mould and mildew. Consistent airflow through loft spaces contributes to a dry and healthy roofing environment.
Versatile and Easy Installation
Versatile and designed to fit seamlessly between roofing felt or membrane overlaps, making them suitable for rafter spacings ranging from 400mm to 600mm centres.
Whether your project involves attic roofs or complex joist centres, these vents are adaptable to various roof designs.
Integral Clips
The integral spring clips ensure a quick and straightforward installation, allowing homeowners to achieve effective roof space ventilation without professional assistance.
Commitment to sustainability
Timloc manufactures cost effective, high-quality roof ventilation products from a proportion of recycled content, ensuring that your choice supports environmental preservation without compromising performance.
Discrete Profile Design
The slim profile allows for easy installation to provide ventilation between roofing felt / roof membranes, providing permanent roof space ventilation at a reasonable price.
How Many Lap Vents Do I Need?
For typical roof ventilation, install one lap vent in every alternate rafter space at a low level on both sides of the roof. This provides effective cross-flow ventilation throughout your loft space.
Each vent provides 3,000mm² of additional airflow and is compatible with rafter spacings from 400mm to 600mm centres.
The number of vents needed depends on your roof's dimensions and the ventilation requirements of your loft space.
Install in every rafter space for maximum ventilation, including at higher levels, to increase airflow throughout the roof.
To summarise:
Standard Ventilation: Alternate rafter spacing - 1 unit for every other rafter space at a low level.
Maximum Ventilation: Install at a high level and in every rafter space along the full length of the roof.
Proper installation on both sides of the roof ensures adequate cross-flow ventilation, reducing condensation and maintaining a healthy roof environment.
How to Install Lap Vents
Loft lap vent installation is a simple process that can significantly enhance the ventilation of your roof space.
- Prepare: Ensure the clips are facing inward toward the roof space, and the flat surface is against the roof.
- Insert: Slide the pointed edge of the vent between the roofing felt or membrane overlap.
- Secure: Push the vent flat towards the roofline, ensuring the clips hook onto the outer face of the felt or membrane.
- Repeat: Install one vent in every alternate rafter space at a low level for standard ventilation. For maximum airflow, consider placing lap vents in every rafter space and at higher levels in the roof.
Note: Lap vents are a supplementary ventilation solution and may not meet the minimum roof ventilation requirements outlined in British Standard BS5250. Additional ventilation methods, such as ridge or tile vents, may be necessary.
