Fenestration & Glazed Facades · NRM2 Section 24 & 25 (Doors, Windows & Curtain Walling)

UK Doors, Windows & Curtain Walling Estimating Services

Itemised opening-by-opening fenestration and internal doorset schedules checking plan marks against elevations, acoustic/fire ratings, and ironmongery.

How is doors & windows measured under RICS NRM2?

Nothing derails a fenestration or fit-out bid faster than mismatched architectural window schedules and plan openings. We reconcile every opening—PPC aluminium frames, composite heritage casements, structural glass roofs, automatic entrance doors, and FD30S/FD60S fire doorsets.

  • Cross-checks structural opening width/height against elevation drawings and highlights conflicts in an RFI tab.
  • Distinguishes Part Q laminated security glass, acoustic attenuation dB units, and obscure bathroom glazing.

Doors & Windows Estimating FAQs

Do you check if window schedules match what is actually drawn on plans and elevations?

Yes. Discrepancies in opening counts, handing (LH/RH), fire escapes, or U-values/acoustic specs are flagged immediately on our discrepancy log.

Are pressed aluminium cills, cavity closers, and expanding foam/Compacfoam packs included?

Yes. Cill projections, head closers, perimeter EPDM weather-sealing, and acoustic mastic are itemised cleanly.

Do you measure internal frameless glass office fronts and sliding pocket doors?

Yes—acoustic double-glazed office fronts, manifestation films, and concealed pocket door tracks are counted by unit and metre.
