Technical guides & advice.
Short, practical information on windows and doors, glazing, energy performance, maintenance, pergolas and steel constructions.
Replacing windows: what to check before you ask for a quotation
A meaningful comparison is not made on the profile series and the final price alone.
Read →Colours & surfacesPowder coating: Class 1 or Class 2?
What powder coating offers, and what the super durable classes add.
Read →Care & warrantyCleaning and maintaining windows: the basic rules
A little proper care prevents problems and preserves both appearance and function.
Read →Steel constructionsSteel fabrication: quality begins before the paint
Sections, detailing, welds, drainage and corrosion protection work as one system.
Read →Quality & certificationCE, FPC and the Declaration of Performance: what they mean for your window
Not simply paperwork — this is the technical documentation of the production process.
Read →GlazingDouble or triple glazing? Low-E, argon, safety and warm edge
The right build-up depends on the opening, the orientation and the actual aim of the project.
Read →Windows & doorsHinged or sliding? Where each one wins
Space, weathertightness, large dimensions and the way the opening is used day to day.
Read →Energy performanceUw, Uf and Ug: what the numbers on a window mean
Three different quantities that are often confused in a quotation.
Read →InstallationWhy a good window can still perform badly
Fixing, joints, sealing and final adjustment are part of the system.
Read →PergolasFixed or bioclimatic pergola?
The answer is not only a matter of appearance or of price.
Read →Steel constructionsSteel mezzanine: loads, stiffness and safety
The intended use has to be known before the choice of sections begins.
Read →Care & warrantyA house by the sea: what changes in maintenance
Salt makes both the cleaning interval and the choice of finish far more important.
Read →GlazingWarm edge: why the spacer bar between the panes matters
Swisspacer, Thermix and other thermally improved solutions work exactly at the most sensitive part of a double glazing unit.
Read →Steel constructionsGalvanising or a paint system?
Corrosion protection is chosen for the structure and the environment, not for the final colour alone.
Read →Windows & doorsThermal break: what it is and when it really counts
A thermal break reduces the thermal connection between the outer and inner side of the profile.
Read →GlazingLaminated or tempered?
Both are safety glass, but they behave differently when they break.
Read →Windows & doorsAcoustic performance in windows
Acoustic comfort does not depend on the thickness of the glass alone.
Read →PergolasWater and drainage in pergolas and canopies
Managing the water is a fundamental part of the design.
Read →Steel constructionsSteel staircase: from the survey to the finished installation
A good staircase combines geometry, stiffness, safety and a clean fit into the space.
Read →Care & warrantyWhen does a window need servicing?
Adjusting it in good time can prevent wear to the hardware and the gaskets.
