Glazed Roof Access Hatch

•   Double or Triple Glazed domes
•    3 kerb options
•    Sleek, low rise dome
•    Large daylight area
•    Secure fixings
•    Can be fitted on roofs with pitch up to 15°
•    U Value as low as 1.2 W/m²K for Triple Glazed with 150 or 300mm PVC kerb

A high quality roof hatch fitted with gas struts to gently open to 90° for access. Our sleek design features an aesthetically pleasing low rise polycarbonate dome fitted to a choice of PVC kerbs. The dome cassette is attached to the kerb using innovative security fixings which spin once they reach a certain torque. This means they cannot be accidentally overtightened during installation but also cannot be undone without a specialist tool (one supplied with each hatch). Each hatch is fitted with a secure handle which allows manual opening. The entire range has been independently tested and accredited by the British Board of Agreement (BBA) or by EN 12101 assessments and is CE marked in accordance with BS EN 1873 or EN 12101 testifying compliance with Building Regulations and industry good practice.

Kerb Options
DF Kerb - a 100mm PVC kerb designed to be fitted to an existing up stand
150mm kerb - Multi-wall construction with superior thermal performance – Fits straight to roof deck, the kerb foot radius is designed to allow the easy application of roof covering up to the termination point/ membrane clamp.
300mm kerb - Multi-wall construction with superior thermal performance – Fits straight to roof deck Taller kerb useful where additional insulation is being added to the top of the roof
The 150mm and 300mm kerbs slope at a steeper angle than some rival products. This results in a larger daylight area (25% on small sizes and 10% on big sizes). Additionally it means a bigger clear area for access.
Kerb height – 150mm and 300mm refers to the membrane termination height, the actual height to the top of the kerb is 216mm and 365mm respectively.

Dome
We use UV stable Polycarbonate for our dome cassettes. Polycarbonate is 200 times more impact resistant than glass. The triple glazed dome features 3 separate layers which means there is no cold bridge which can occur when layers touch. This minimises the risk of condensation. Available in 3 colour options.

Thermal efficiency

To comply with Part L Building Regulation requirements roof domes must achieve a U value of 2.2 W/m²K or lower. Our 150mm and 300mm PVC kerbs achieve the following U-Value range
Double Glazed with 150mm or 300mm PVC Kerb 1.6 – 2.1 W/m²K (exceeds thermal requirements of Part L in all sizes)
Triple Glazed with 150mm or 300mm PVC kerb 1.2 – 1.5 W/m²K (exceeds thermal requirements of Part L in all sizes)

Please note the DF kerb is less thermally efficient (Double Glazed 2.7 W/m²K Triple Glazed 1.8 W/m²K)

Fitting & installation instructions
Each hatch is supplied with fitting/ installation instructions. The hatch is designed to be fitted to a range of roofing systems including single ply, bituminous, metal and liquid applied. This versatile product is suitable for a wide range of flat roof applications. Ideal for new builds and refurbishment projects, this product is routinely used for both residential and commercial projects. (Please note while we describe this as a flat roof product it can be fitted to roofs with a pitch not exceeding a 15°)
