1 Stairs, Windows, Doors, and Roofs

2 Stairs They are subject to detailed requirements under Building Regulations Approved Document KBuilding Regulations Approved Document K –in respect of pitch, width, headroom, guarding, landings and treads. –All stairs are required to have protection to prevent people falling from height. This can be provided by traditional timber balustrading and handrails. ex: balustrades balustrades

3 Stairs Most stairs are generally constructed in timber, steel or concrete, although there are some fantastic glass stairs around. See our page on glass stairs for some good examples.timbersteelconcreteglass stairs Spiral stairs are useful when you have restricted space, but can be complicated to set out. Small spiral and spacesaver stairs and ladders are useful for loft conversions.Spiral stairsspacesaver stairs and ladders

5 Stringer: the long, diagonal supports that run the entire length of the stairs. –The supports are blocked, cut or notched to accept the individual treads and risers. – There are usually two stringers, one on each side and occasionally a third in the middle. Tread: is the flat surface that is stepped on; the width of the tread is equivalent to the run. Riser: is the vertical component; the height of the riser is equivalent to the rise. Stairs without risers are called "open" stairs.

7 The maximum height of the riser (or rise that a person needs to step up to the next stair) is 8 to 8-1/4 inches. The riser's height should not vary more than 1/2 inch between the shortest and tallest risers. The minimum width of the tread (or run) on which a person places their foot is 8 1/4 to 9 inches. –If a stair is more than 44 inches wide, a handrail is required on both sides.

8 Stairs Tread should be level with a maximum deviation of a 2% slope. To ensure stability, the minimum width at any point of stringer should be 3-1/2 inches. A vertical clearance of 6 feet 8 inches needs to be maintained between the stair and ceiling at all points. The stairwell must be a minimum of 36 inches wide.

9 Landings –Most fire codes do not allow stairs to rise more than 12 feet without providing a landing. –The length of the landing should be at least equal to the width of the stair tread. Balustrade –According to the 1996 COBE code, the openings between balusters is to be no greater than 4 inches. Smaller holes reduce injuries to young children. –The balustrade is topped by a handrail 30 to 38 inches above the top of the stringer; the handrail's grip size is between 1¼ to 2 inches. –If the handrail is mounted on a wall, a space of at least 1½ inches must be left between the edge of the handrail and the wall.
