opening double or single glazed light. The integral lower flashing (1.3mm lead for Purilan UNV and sheet aluminium for Purilan L models) removes the need for a separate, difficult-to-seal site joint between frame and flashing for most situations, thus providing for easier installations.

The casement stay is designed to hold the skylight casement in three positions – it may also be released from the frame for even wider opening. Units with the suffix E are external locking with a single barrel lock.

Purilan skylights are ideal where ventilation and light are required via the pitched roof finish. With specialist units for both slated and tiled roofs and the choice of single and double glazing, they are suitable for workrooms or hobby areas and for corridors and stairwells. The Purilan is also particularly suited for the replacement of cast iron skylights. The external locking units are produced for situations where a pitched roof is added to an existing flat roof and services requiring maintenance are then isolated in the newly created roof void.

the popular styles of ridge tiles. Uncapped

vents allow you to use your own choice of

ridge tile while still complying with building

regulations.

Ridge Vents

The VRC is a vented ridge tile comprising a metal under ridge vent combined with a PVC-u moulded cap which can be supplied in standard roofing colours or coloured & textured to individual requirements.

For high level ventilation each 450mm long Capped Ridge Vent provides a 12,500mm2

free vent area – 6,250mm2

on either side of the ridge. To achieve the equivalent of 5mm continuous ventilation on either side of the ridge they should be fitted every 1.25 metres. Incorporated in each unit is an expanded metal mesh insect screen to inhibit large insects and vermin.

VRC vents are installed by bedding in mortar and securing via the predrilled fixing strips to a suitable roof timber. There are VRC vents for both segmental and angled ridge tiles.

Matching units are also available for the termination of building services – See Ridge Terminals on page 29.

VRC Capped Ridge Vent

Metal Ridge Vents provide roof void ventilation on either side of a conventional ridge tile. The width of the vent can be adjusted to suit individual types of ridge tile by releasing/ tightening a slotted screw.

There are two sizes of MRV available to suit 305mm and 450mm ridge tiles and the free vent areas provided are 6010mm2

and 9000mm2

respectively. To achieve the equivalent of 5mm continuous ventilation on either side of the ridge, they should be spaced as follows:

305mm – every 0.6 metres 450mm – every 0.9 metres Each vent has an integral expanded metal insect inhibitor. This mesh continues under the vent to aid grip to the mortar bed.

MRV Metal Ridge Vent

The MRV is installed underneath a standard hip tile or trimmed ridge tile in order to maintain the ridge line. Each unit is mortared in place and also mechanically fixed via the predrilled end fixing strips. The ridge tile is then mortared onto the vent.

•Semi-rigid hinged underlay support flap

OFVS Over Fascia System

roof pitches 15° - 70° although below 23° additional support may be needed for the support flap to prevent ponding: OFVS10 & OFVS/10L provide 900mm length x 10mm continuous ventilation OFVS25 & OFVS25/L provide 480mm length x 25mm continuous ventilation The interlocked strips are nailed to the top of the fascia and nail fixings should be calculated in accordance with BS5534. The fixing points are designed to eliminate any water leakage as are the interlocks between strips.

It should be noted that some cellular PVC-u fascia boards cannot take vertical fixings. In such cases the system may be fixed through its underlay support into a batten fixed to the rafters behind the fascia board. However, space must be left between the back of the fascia board and the fixing batten to allow air to pass into the roof void.

In full boarded roofs, a section of boarding immediately behind the fascia should be removed to allow air to pass into the roof void.

At hips and valleys, the system should be sawn to form tight fitting mitred joints. To prevent possible leakage at valleys, a flashing of underlay material should be positioned under the joint to discharge into the gutter.

Abutment

Vents

The Ubbink Lean-to Abutment Vent is an interlocking system which provides a continuous 5mm of ventilation where a monopitch roof abuts a wall. Each strip of LTV provides 900mm working length.

The spacers provided are positioned behind a batten which is fixed to the wall above the abutment joint. This allows the ventilation introduced by the LTV strip to pass behind this batten into the roof void. A lead strip is attached to the front of the batten and dressed down over the roof finish. The LTV vented strip is nailed to the top of the batten. A further strip of lead is raggled into the nearest mortar joint above the fitted strip, dressed down over the LTV and held tight to it by the integral stainless steel clips.

LTV Lean-to Roof Vent

The Metal Mono Vent provides the equivalent of a continuous 5mm of ventilation where a monopitch roof abuts a wall.

Metal Mono Vents are available in two sizes:

345mm long x 150mm wide x 19mm deep for use with rafters at 400mm centres

545mm long x 150mm wide x 19mm deep for use with rafters at 600mm

Metal Mono Vent

The following are the free ventilation areas of the units and the spacings necessary to achieve the equivalent of 5mm of continuous ventilation:

345mm long – 5,440mm2

– every 1 metre (adjusted to nearest rafter spacings)

545mm long – 8,640mm2

– every 1.7 metres (adjusted to nearest rafter spacings)

These units are V-shaped funnels which incorporate an integral expanded metal insect inhibitor. Installation is by slotting into place between the rafters and the abutment joint is then weathered by a lead flashing strip which is raggled into the mortar joint above the abutment and dressed onto the Metal Mono Vent. The gap between the underside of the vent and roof finish should be sealed.

The Ubbink Eaves Protection System is designed for use in both refurbishment projects and new build to provide an effective level of eaves protection. The 1.5m rigid pre-formed strips are suitable for use in roof pitches of 15° to 70°. On existing buildings EPS can be used to replace rotted gutter felt with the minimum of disruption to the existing slate or tile roof covering.

In new build situations, the preformed EPS strip directs water away from the underlay and into the gutter. At the same time it provides an effective underlay support flap, preventing ponding of the underlay behind the fascia board. EPS is ideal for use with the new generation of lightweight, high performance underlays, which are not suitable for forming a drip into the gutter. EPS is fixed to the top of the fascia with clout nails. If a plastic fascia is used which will not support clout nails, EPS may be fixed to a batten behind the fascia.

Non-lead Flashing

Ubiflex is a non-lead flashing material which can be used in all applications where lead is traditionally installed. Ubiflex is environmentally friendly, non-toxic and recyclable.

UBIFLEX - SETTING NEW STANDARDS IN FLASHINGS

Ubiflex is 80% lighter than lead - giving handling, structural and health and safety advantages. Ubiflex is fully malleable, can be worked in both directions and is self-sealing if punctured.

Ubiflex allows aprons up to 12m long with 400mm width and below to be formed without seams. There is less wastage with Ubiflex than with traditional materials.

Ubiflex is up to 50% quicker to install than lead.

Ubiflex is compatible with all common building materials and components, such as thermal panels, extract flues, ventilators and rooflights.

Ubiflex does not cause unsightly staining.

Ubiflex is only of value to the installer; it has no re-sale value as scrap.

APPLICATIONS

Ubiflex is suitable for all applications where lead would traditionally be used: • Stepped flashings

• Abutment flashings • Chimney flashings • Saddle flashings • Pitched valleys liners

Ubiflex

• Rooflights and solar panels • Dormers

• Ubiflex can also be used to form damp proof courses and cavity trays in masonry walls.

INSTALLATION

Ubiflex can be worked in the same way as lead, but without the need for protective measures.

Ubiflex:

• Can be cut with a sharp knife • Can be fixed with stainless steel nails if

required

• Should be lapped or sealed with Ubiflex High Tack Lap Sealant • Is compatible with all common

building materials except PVC Single Ply Membranes

Ubiflex Gap Sealant is designed for pointing joints in brickwork or masonry and provides a flexible, long life joint which avoids the cracking and water penetration problems associated with traditional mortar.

Ubiflex Fixing Clips grip Ubiflex firmly in place in seconds and allows Ubiflex to be easily dressed before pointing in.

Multivap 300 breather underlay provides outstanding protection against wind-driven rain and water infiltration. Yet its vapour permeable surface allows moisture vapour to escape, helping to keep interiors condensation free.

CONDENSATION

With modern standards of insulation it is necessary to dispel the accumulation of moisture vapour in occupied buildings. In principle, ventilation dispels moisture and stops condensation forming. The first line of defence is a vapour control layer on the warm side of the insulation. However water vapour can occur and must be dealt with. Multivap 300 with its high vapour permeability

Multivap 300

allows vapour to pass freely through to evaporate in the atmosphere.

INSTALLATION ON PARTIALLY SUPPORTED COLD ROOFS

Multivap 300 should be draped over the rafters to allow any water ingress through tiles to drain down to the gutter. Overlaps must be provided with the minimum dimensions given in the following table.

A prefabricated gutter drip must be used with Multivap – Ubbink Eaves Protection System – see page 20, or Over Fascia Ventilation System – see page 15, are suitable.

For sealing overlaps or junctions with adjoining materials, use Ubiflex Tack Sealant.
