Plaintile Overview

Britmet Lightweight Roofing’s Plaintile system is the world’s only true broken bond Plaintile lightweight roofing system. The only tile to give a true characteristic of a traditional Plaintile, providing an attractive and economic finish for all roof styles, even for vertical cladding.

Britmet’s Plaintile system can be fixed down to a 15° roof pitch and is highly effective at reducing installation time as it’s 7 traditional tiles wide and on tile high. This means that only 5 Plaintile panels are required per sqm. This is a huge difference in comparison to traditional plain tiles which required 60 tiles per sqm.

Available in 6 colours and weighing 1/7th the weight of traditional tiles, the Britmet Plaintile is manufactured in Britain from the highest-grade Aluzinc Steel and coated with the most superior external coating on the market for effortless weather protection.

Plaintile General Specification

Plain Tile panels roof pitches from 15° to 90°

Plain Tile lightweight roofing tiles, to be supplied by Britmet.
Each tile must be secured using 4 coloured 2.6mm x 50mm galvanised fixing nails, driven through the downturned nose of the tile into the face of the battens.

Battens
Treated tiling battens of approved quality (E.g., tanalised), of suitable section, should be laid at 160mm centres, (for 0.45mm thick) except the eaves batten (see eaves section), and secured to the rafters using galvanised nails. Joints in the battens should be staggered and meet halfway across the top of the rafters, as standard code of practice.
Please note: It is the responsibility of the installer to ensure correct batten usage

Underlay
Approved reinforced felt, BS747 (Type 1F) must be laid over rafters, lapped and secured to the rafters with galvanised clout nails and carried well into gutters. All to comply with current regulations.

Angle Ridge Flashing
Two tile battens should be fitted side by side on both sides of the ridge using galvanised nails. An additional 50mm x 50mm batten is to be secured on top of the rearmost of the two tile battens in a position to suit the fitting of the Plaintile angle ridge.
If necessary, the top course of tiles can be cut and bent using a guillotine and bender (available to hire from Britmet). The rear edge of the tile is to be turned up to form a 25mm - 38mm upstand against the top tile batten. Each tile must be secured using 4 nails driven through the downturn as previously described.
The angle ridge flashing is to be fitted over the top batten and nailed through the downturn of the ridge into the tile upstand and face of the batten, using 5 nails on each side.

Angle Ridge (ventilated) Roof Pitches From 10° To 35°
Felt underlay must be cut back allowing a continuous 12.5mm air gap on either side of the centre line of the ridge.
If necessary, the top course of tiles can be cut and bent using a guillotine and bender (available to hire from Britmet). Each tile can then be secured using 4 fixing nails driven through the downturn nose of the tile and into the battens. A batten, not exceeding 50mm x 50mm should be fitted on the universal vent piece (supplied by Britmet) and secured through the tile into the battens on the underside, using 75mm galvanised nails.
The ridge flashing should be fitted over the batten and nailed through the downturn into the face of the batten using 5 nails on each side.

Angle Hip Flashing
A 38mm x 38mm hip batten is to be nailed to the tile battens on each side of the hip rafter using galvanised nails.
Tiles should be cut and bent to form a 25mm - 35mm upstand against the hip battens, using a guillotine and bender (available to hire from Britmet).
The hip flashing is to be fitted over the battens and nailed through the downturn, into the face of the battens using 5 nails on each side.

Eaves
The bottom course of tiles is to be secured using 4 coloured 2.6mm x 50mm galvanised fixing nails. These must be driven vertically through the tile, as near to the high point of the tile profile as possible and into the fascia board or through the eaves batten placed approx. 20mm behind the fascia board if the Plaintile eaves ventilation system is used. These nail heads will then be sealed using the Plaintile touch-up kit.
If using the top of the fascia board or eaves vent, this must be in line with the top of the battens.
Then, fit Lay Board or Tilting Fillet at the eaves if appropriate, to ensure any moisture on the underlay drains into gutter.

Eaves Ventilation
Roof pitch above 15°
The top of the fascia board should be fixed 23mm below the top face of the eaves batten allowing for the Plaintile 10mm eaves vent system.
Roof pitch below 15°
The top of the fascia board should be fixed 25mm below the top face of the eaves batten allowing for the Plaintile 25mm eaves vent system. Note: Where the insulation follows the roof slope, the Plaintile ventilation tray should be installed between the rafters.

Valley
The valley should be formed from lead, moulded glass fibre or similar approved lining, supported on valley boards.
Tile battens should project over the valley to provide fixing for the tiles.
Plaintile panels should be measured, cut and bent using a guillotine and bender (available to hire from Britmet), allowing sufficient downturn into the valley.

Barge Board Cover
The timber barge board should project 25mm above the top of the tile battens. A 50mm x 50mm timber batten to run parallel to the fascia board. Plaintile panels should be cut and bent up against the timber barge batten.
The Plaintile scribed barge board cover is to be secured using 5 fixing nails driven through the downturned edge into the barge board and 5 nails to be driven vertically into the barge batten (the heads of the vertically fixed nails to be sealed, using the Plaintile touch-up kit).

Sidewall Flashing
Plaintile scribed sidewall flashing should be secured using fixing nails, one driven vertically into each batten (these nail heads need to be covered, using the Plaintile finishing kit).
Plaintile cover flashing should then be dressed over the vertical section of the side wall flashing and dressed into the brickwork.

Plaintile Inline and Soil Vent
To provide additional ventilation, the Plaintile inline tile vents are available, providing an airflow of 7,500mm2.
The tile underlay must be cut to allow the spigot of the tile vent to pass through. The Plaintile panel vent is installed to provide full weather security. The tile vent is secured by overlapping a Plaintile panel on either side and nailing through the nose of the tile, as previously described. Nails must not penetrate the vent tile.
The Plaintile inline vent tile can also be used as a weather protected exit point for soil pipes or extractor fan ducts by means of a flexi-hose and pipe adapter that connects the vent to 100mm stacts or duct work.

Plaintile Gas Flue Ridge Terminal
Available to suit angle ridge. Type (R) adapter and extension piece supplied by others.
