Slimtech Heritage units are slim double glazed units designed for traditional and historic windows where narrow cavities and low sightlines are important. They combine discreet proportions with modern low-E glass, insulating gas and warm-edge spacer technology.

Yes. Trinity Glazing provides glass cut to size for trade and public customers. Glass can be produced for windows, shelves, tabletops, splashbacks, screens and many other domestic or commercial uses.

Yes. Trinity Glazing supplies uPVC windows, doors, sealed units, mirrors and many types of glass to builders, joiners, window fitters, developers and other trade customers.

Replacement windows can reduce draughts, improve thermal efficiency, increase security and refresh the appearance of your property. Modern uPVC windows also require less maintenance than many older frames. Trinity Glazing supplies energy-efficient replacement windows for homes and commercial properties across Edinburgh and the Lothians.

Signs include persistent draughts, condensation between the panes, damaged frames, difficult operation, water ingress and noticeable heat loss. A professional assessment can determine whether you need a full replacement window or only a replacement glazed unit.

Yes. Modern uPVC windows use insulated multi-chambered frames, energy-efficient glass and warm-edge spacer technology to reduce heat loss. The overall performance depends on the complete window specification, including the frame, glazing, seals and installation quality.

Popular options include casement windows, tilt-and-turn windows, French windows, sash-and-case style windows, flush-fit windows and shaped frames. The best style depends on your property, ventilation needs, preferred appearance and any planning restrictions.

Yes. Period homes may benefit from carefully selected sash-style windows, secondary glazing or Slimtech Heritage double glazed units. These options can improve comfort while helping retain the traditional character and proportions of older windows.

Well-made and correctly installed uPVC windows can provide decades of service. Their lifespan depends on exposure, maintenance, hardware quality and installation. Regular cleaning and occasional lubrication of hinges and locking points can help maintain performance.

Modern replacement windows can improve security through stronger frames, secure glazing, multi-point locking and improved hardware. The exact security features vary by product, so ask for a specification suited to your property and location.

Double glazing can reduce everyday external noise, while laminated glass or specialist acoustic specifications can provide further improvement. Results depend on the glass thickness, cavity, frame seals and the type and frequency of the noise

Yes. Bespoke mirrors can be cut to the required size or shape for bathrooms, bedrooms, gyms, shops, offices and interior design projects. Simple rectangular mirrors may be available with a particularly quick turnaround.

Composite doors combine multiple materials to provide strength, insulation, weather resistance and a wide choice of styles. They are a popular option for homeowners seeking improved security and a substantial entrance-door appearance.

A double glazed unit contains two panes of glass separated by a sealed cavity. The cavity may contain argon or krypton gas, and the unit can include low-emissivity glass and a warm-edge spacer to improve thermal performance.

Yes. Trinity Glazing manufactures double glazed units for domestic and commercial projects, with a range of glass types, cavity widths, spacer colours and gas options. Bespoke sizes allow units to be produced for both new frames and replacement work.

Misting between the panes usually indicates that the sealed unit has failed and moisture has entered the cavity. The frame may still be serviceable, so replacing the glass unit alone can often restore clarity and insulation.

The usual long-term solution is to replace the failed sealed unit rather than attempting to remove the moisture. A new unit can be made to the correct size and specification while retaining the existing frame when it remains in good condition.

Internal condensation occurs when warm, moisture-rich air touches a colder surface. Better ventilation, consistent heating and efficient glazing can help. Condensation between the panes is different and normally points to a failed sealed unit.

Low-emissivity, or low-E, glass has a specialist coating that reflects heat back into the room while allowing daylight through. It is commonly used in energy-efficient double glazing to reduce heat loss.

A warm-edge spacer separates the panes around the perimeter of a sealed unit while conducting less heat than a traditional aluminium spacer. It can improve edge-of-glass temperatures and help reduce the risk of condensation near the frame.

Argon is an inert gas used inside many double glazed units to improve insulation compared with ordinary air. The final benefit depends on the cavity width, glass type, spacer and quality of manufacture.

Double glazing slows heat transfer through the window and helps keep the inner pane warmer. Low-E glass, insulating gas, warm-edge spacers and well-sealed frames can all contribute to improved thermal performance.
