We work with architecture studios, project managers and developers on the Costa del Sol. This page gathers the technical information usually requested at design stage and in tenders: CE marking of the systems, compliance with the Spanish Technical Building Code (CTE) and thermal transmittance calculations.
CE marking and Declaration of Performance
Every system we supply is installed with its CE marking and the manufacturer's Declaration of Performance (DoP). The relevant harmonised standards are:
- UNE-EN 14351-1 — windows and external pedestrian doors.
- UNE-EN 13830 — curtain walling.
- UNE-EN 12600 — classification of glass under pendulum impact.
We hand over the DoP for each system together with the site documentation.
CTE DB-SUA — safety in use
Glass balustrades and parapets are designed to the SUA Basic Document of the Spanish Technical Building Code and the actions defined in DB-SE-AE:
- Horizontal load on the top edge: 0.8 kN/m in private and residential areas and 1.6 kN/m in areas open to the public (CTE DB-SE-AE, table 3.3).
- Barrier height: 0.90 m for drops of up to 6 m and 1.10 m for greater drops (DB-SUA 1).
- Impact safety: laminated glass classified to UNE-EN 12600, in accordance with DB-SUA 2.
Uw thermal transmittance and energy efficiency
We calculate the thermal transmittance of the opening (Uw) to UNE-EN ISO 10077-1, combining the frame (Uf), the glazing (Ug) and the spacer. For every project we provide:
- Valor Uw for each type of opening, compared against the CTE DB-HE 1 requirements for the relevant climate zone.
- Solar factor of the glazing (g) and a solar control solution where the orientation requires it.
- Air permeability (UNE-EN 12207), watertightness (UNE-EN 12208) y resistance to wind load (UNE-EN 12210).
Documentation we provide
- Technical report and system data sheets (Cortizo, Reynaers, Schüco, Aluprof).
- Declarations of Performance (DoP) and CE marking.
- Uw calculation per opening and justification against CTE DB-HE.
- Structural calculation of balustrades and glass to DB-SUA and DB-SE.
- Shop drawings and construction details for fixings and sealing.
- Works programme and on-site acceptance protocol.
Technical audit of the project
We review your glazing design and issue a fixed quote within 5 working days: an engineer's site visit, a drawings review and a written fixed price, with no obligation.
