Windows & Door Installations in Kilmarnock
Although inland, Kilmarnock is still influenced by west-coast weather patterns, bringing cool temperatures, frequent rainfall and seasonal winds. As a result, older homes may be more prone to heat loss, draughts and condensation, particularly during colder months. As a regional centre, Kilmarnock also experiences higher traffic levels around key routes and the town centre.
Double glazed windows and doors help address these challenges by improving thermal efficiency, weather resistance and sound insulation. Modern glazing reduces heat loss, supports more stable indoor temperatures and helps manage energy costs more effectively. At RePlace Windows, we supply German-manufactured double and triple glazing systems precision-engineered to enhance thermal insulation.

Our Services
RePlace Windows provide high-quality double glazing in Kilmarnock. Double glazing consists of two glass panes with an insulating air gap in between. The air gap is a weak thermal conductor, helping slow heat loss.
Our double-glazed units are around 28mm thick and feature low-emissivity (Low-E) glass. They provide various benefits:
- Up to 64% reduction in heat loss compared to single glazing
- Lower energy bills due to decreased need for heating
- Improved sound dampening in busy areas
We offer double glazing on a variety of window styles, including sash windows, tilt and turn windows, casement windows and bay windows.
Our triple glazed windows units consist of three glass panels and are about 44mm thick. These windows offer advanced features in comparison to traditional double glazing.
Triple glazing offers various advantages, including:
- Increased property aesthetic and resale value
- Minimised condensation and heat loss
- Maximised sound insulation
Our triple glazing can be fitted to most uPVC units and composite doors, with the exception of patio doors.
We provide high-quality uPVC windows across the Kilmarnock area. Our uPVC window frames are made from a thermoplastic called Unplasticised Polyvinyl Chloride. This material is known for its versatility, resilience and recyclability.
Our uPVC window frames are fitted with modern VistaTherm Elite glass. They are available in a variety of styles and colours, including French doors and patio doors. Each unit can be fitted with double, triple or acoustic glazing and is made to measure, ensuring a perfect fit.
Our uPVC doors feature the same benefits as our uPVC windows. They come in a range of colours and styles, including bi-fold doors, patio doors and French doors. These doors are a more affordable alternative to hardwood or composite doors, adding kerb appeal and increasing home value without breaking the bank.
Our uPVC doors boast various benefits:
- Highly customisable to achieve your desired visual aesthetic
- Durable and secure with multi-point locking systems
- Exceptional energy efficiency rating
- Low maintenance and durable
Our composite doors feature a multi-layer construction, including a solid timber core, aluminium ‘u’-rail for reinforcement and a hard-wearing glass reinforced plastic (GRP) outer skin. These doors are popular for their enhanced durability and strength, and provide an added layer of protection to residences.
Composite doors are popular in areas like Kilmarnock as they help guard against harsh winds and heavy winter rain. Air-tight and water-resistant, these German-engineered doors don’t degrade or warp under harsh weather conditions or heavy use.

Frequently Asked Questions
High quality windows and doors fitted with double glazing improve energy efficiency by reducing heat loss and preventing draughts, helping homes stay warmer with less energy use.
They do this by:
- Using two panes of glass with an insulating air or gas gap to slow heat transfer
- Improving sealing around frames, reducing draughts and heat leakage
- Maintaining more stable indoor temperatures so heating systems run less often
By keeping heat inside during colder months, double glazing helps lower energy consumption, improve comfort and reduce heating costs over time.
We offer acoustic glass windows, which are typically made using a combination of glass, laminates and special acoustic seals. The glass used in acoustic glazed units is often thicker and heavier than standard normal glass and may be laminated or tempered. These windows are ideal for schools, offices or homes in busy areas or near highways.
