What fixing is required?

It depends on site location and exposure. Generally, tiles
are nailed at 25º and above and tail clipped below 25º. On all roofs, the perimeter tiles (i.e. tiles at eaves, verges, ridges and alongside valleys and abutments) should be nailed or clipped.

Along the East Coast and in the midlands, every tile in alternate courses should be nailed or clipped. Along the west and south coasts, all tiles must be nailed or clipped (see map in brochure for boundaries).

How are clips fixed?

Clips are fixed at the tail of the tile and nailed to the side of the batten holding the course below. Roadstone Wood supply batten clips and special clips for the verges and eaves.

What kind and size nails are used?

Aluminium nails available from us. Double Roman – 65mm, RSS – 50mm, Spanish Roll – 75mm.

What mix is used for wet bedding of verges and ridges?

3:1 (Sand:Cement) Do not use a lime mortar. You will also need dye for the pointing, usually 6kgs (30 ridges) for a standard house. Not to exceed 5% per volume of cement.

Ventilation

In order to comply with building regulations, all roofs must be ventilated. We supply Eave and Ridge ventilation systems. We also supply ThruVent Tiles and Vent Ridge Tiles.

Other Accessories

What are Cloaked Verge Tiles?

These tiles continue the tiling over the gable end using a one-piece concrete tile. They are mechanically fixed, eliminating the need for mortar bedding. They provide high resistance to wind uplift, are maintenance free and provide a neat finish to a verge.

What other dry fix fittings are available?

The Dry Hip System provides a neat and attractive finish to the hip line without the use of mortar.

High Yield Stainless Steel rods (6mm and 8mm) are recommended, which are 3M in length. These are available ex.stock.

24.Who would you recommend to lay glassblocks?

A good bricklayer, preferably one who has laid them before?

25.How are they laid?

They are laid in special glass block mortar (10-12mm joints) with reinforcement vertically and horizontally in the joints (generally every second course) and pointed with the sameglass block mortar. Glass block mortar is available from Roadstone Wood Dublin, Huntstown, Dublin 11.

Control joints usually 6m centres (10mm wide).

17. Is there technical backup available?

Yes.Make full use of Technical Represantives experience-he will be happy to help.

General Questions

1. Is it waterproof?

No more than brickwork-most of the penetrations go through the vertical joints, make sure they are filled and compacted-don’t fill the cavity with insulation.

2. Does it discolour in time?

Fading in colour concrete happens when the pigment wears off the face of the aggregate stone. As Hallmark is split textured right through the aggregate it is therefore ready weathered. Weathering will always occur on walling material due to dust and the atmosphere.However all concrete will weather a little.

3. Is it easy to build and will it match standard blocks?

Yes it is easy to build and suits standard blockwork.

4. Is it subject to lichen or moss growth?

No more than any other wall finish when properly laid with proper overhangs.

26. Which is the most popular brick, which looks the best?

Grange Range Autumn Blend in light brown mortar.

General Questions

27. Are Huntstown bricks waterproof?

They are no more waterproof than a clay brick wall. Most of the penetration goes through the vertical joints and so you should sure that they are filled and compacted-never fill the cavity with insulation on any unplastered walls.

28. Will the brick fade or discolour in time?

Weathering in coloured concrete occurs when the pigment eventually weathers off the face of the aggregate stones. Adequate overhangs at cills and roof will protect the walls. Natural weathering will occur on any walling materials due to dust and atmospheric conditions.

29. Is it subject to lichen or moss growth?

No more than any other wall finish when properly laid with proper overhangs.

30. Will there be colour variation if ordered much later?

This will not be noticeable in the blended colours. In single colours it is possible but it is a natural product.

Min. 35º

What weight?

1.25 tons per 1000 tiles or 76 kg per m² laid.

What batten spacing is required?

100 mm for pitched roofs and 112 mm for vertical cladding.

What happens at the hip?

Bonnet hip tiles course into the tiles. If the pitch is over 50º or the angle on plan is not 90º; mitre cut the tiles and use soakers. Alternatively, use ridge tiles.

What happens at the valley?

Valley tiles will course in if the angle on plan is 90º (max. pitch 50º). Alternatively, a lead valley is suitable.

What fixing is required?

Nail all perimeter tiles and nail each tile in every 3rd course. On exposed sites or for vertical cladding, nail every tile. Use two 40mm aluminium nails per tile for standard battens.

How is the top tile fixed?

It hangs on the top course of full tiles. Use a top tile clip for fixing.

Are they suitable for vertical cladding?

Yes, fixing is the same as for pitched roofs.

What happens at the corners?

Use corner tiles. To keep the bonding line, use left hand and right hand eaves alternatively up along each corner.
