Window sills
- ULMA Architectural Solutions window sills are the pieces designed to evacuate rainwater in the window spans.
- Ideal for any type of construction for being easy to install, as well as for their aesthetics
- With stainless anchorage to guarantee the optimal intallation, avoiding the corrosion of the piece.
Installation
Chip and extract the first brick on each side of the hole where the window sill must be inserted
Generate a support slope using mortar with a very high cement content to form a resistant surface in the area on which the piece will be fitted
Proceed to open the anchors with the pieces on the back, one pin for each side
Apply a layer of elastic adhesive mortar type C2S2 (double glued) to the window sill. Make sure that the adhesive mortar covers and surrounds the anchor
Fit the piece by hammering it, making sure it is level and aligned
Leave a joint of at least 5 mm between the piece and the brick on both sides. Fitting two strips of Porexpan approximately 1 cm thick can acts as a gauge and a joint, since it has a suitable capacity for deformation
Whenever it is necessary to fit more than one piece, place the master next to the piece fitted and mark a 5 mm joint between the pieces
Place the next piece alongside master joint. Hammer, level and align the piece
Clean the joint between the pieces with the master by sliding it outwards, ensuring the joint is perfectly clean across the whole thickness
Proceed to seal the joints with a flexible impermeable element with high adhesion and modulus of elasticity. It is recommended for this element to have good resistance to UV rays to avoid yellowing and cracking. Repeat the operation successively
