Doors, Windows & Glazing Installation
NLS Contractors installs aluminium windows and curtain wall, steel doors, fire-rated door sets and glazing in Riyadh, Jeddah, Dammam, Khobar and across the Kingdom. Wind loads follow SBC 301, glazing thermal values are checked against SBC 601, and handover includes shop drawings, test certificates and installation records.
Doors, windows and glazing are where a building meets the weather, the fire code and the user's hand. The package covers aluminium windows and sliding doors, curtain wall and storefront glazing, steel doors, fire-rated door sets, glazed screens and ironmongery, all installed to approved shop drawings.
Facade systems are designed for wind load per SBC 301, for the thermal performance the glazing schedule demands against SBC 601 (energy conservation), and for the movement of the building. The shop drawings show the fixing brackets, anchors, sealant joints and drainage paths, and the engineer reviews them before the system supplier or fabricator releases the frames.
A fire-rated door is a set, not a leaf. The leaf, frame, hinges, closer, seals and any glazing are tested together to the stated rating, and they are installed to the manufacturer's detail with the specified gaps and fixings. The rating plate and certificate must match the rating on the drawings. Civil Defense approves fire-rated sets and inspects their installation, so the schedule is checked door by door before the inspection is booked.
Installation is where tolerance shows. Frames are fixed to the structure with the specified anchors, aligned plumb and level, sealed at the perimeter and sealed again against the substrate. Facade water tightness is tested on installed bays or a sample area, as the specification states, with the results recorded. Glass is handled, set and protected against damage and marking until handover.
The works package covers supply and installation of the system to the schedule, or installation of client-supplied items, and the offer states which it priced. Send the door and window schedules, the elevations and facade drawings, the glazing performance specification, the fire-rating schedule, the BOQ, the site city, and the access available for hoists or scaffold. Price and lead time depend on the scope.

Frequently Asked Questions
What makes a door set fire-rated?+
The complete assembly tested together to the stated rating: leaf, frame, hinges, closer, seals and any glazing. Replacing one part with an untested one can void the rating.
Why do facade wind loads matter?+
Frames, anchors and glass thickness are sized for wind pressure under SBC 301. Tall buildings and exposed sites see higher pressures, so the shop drawings carry the calculation basis.
How is facade water tightness tested?+
By a water test on installed bays or a sample area, as the specification states, with the results recorded. Perimeter sealant and drainage details are checked first.
Does the offer include supplying the frames and glass?+
The works package covers supply and installation of the system to the schedule, or installation of client-supplied items. The offer states which it priced.
