What Are Double Hung Windows?

Double hung windows serve as an exceptional choice for environments with limited space. Areas such as bathrooms, hallways, and other compact locations gain advantages from single hung windows, thanks to their vertical opening design that optimizes interior square footage.

Double hung windows are equipped with a fixed upper sash and permit seamless operation by allowing the lower sash to slide vertically along designated tracks. The sliding sash of Alliance Windows & Doors can also tilt inward, enabling easy cleaning and maintenance.

Our vinyl single hung windows are expertly manufactured in Canada. They offer complete waterproofing and are built with a durable locking system that ensures both security and user convenience. Vinyl single hung windows from Alliance Windows & Doors are designed to resist fading, cracking, and rusting.

Benefits of Using High-Quality Spacers:

Improved Energy Efficiency: Reducing thermal bridging along the edges of the window means that less energy is lost, contributing to a more consistent indoor temperature.

Minimized Condensation: By maintaining better surface temperatures, good-quality spacers can reduce condensation, which can lead to mold or damage to window frames.

Extended Longevity: Properly designed and certified spacers help maintain the integrity of the window’s insulating gas seals, ensuring that the window system performs well over time without leakage or fogging.

Spacer Types

IGMAC Approval and Certification:

IGMAC (Insulating Glass Manufacturers Alliance) certification indicates that the spacers have been tested and approved according to strict industry standards. This certification ensures that the spacers are durable, provide optimal thermal performance, and are reliable for long-term use.

IGMAC-certified spacers help ensure that the insulating glass units (IGUs) they are part of maintain their seal and thermal performance over time, preventing air leakage or moisture infiltration.
