Indoor HVAC fixings & support

Complete support solutions for HVAC

In indoor HVAC (heating, ventilation and cooling) installers must bring pipework, ductwork and equipment together in often limited spaces. Each service must allow for thermal movement and be securely supported. Further maintaining continuity in insulation and allowing room for maintenance is necessary.

Walraven provides compatible anchors, channel systems, pipe clamps, insulated supports and movement solutions for complete indoor HVAC installations. Together with technical project support you can achieve a dependable result from the structure to the supported service.

What makes indoor HVAC systems complex to install?

Indoor HVAC systems are often installed in crowded spaces such as plant rooms, corridors, ceiling voids and service areas. Loads, pipe movement, insulation thickness, fixing distances and access requirements all influence the support design.

It is vital to select compatible components from the anchor to the pipe or duct.

Support every component of an HVAC installation for better efficiency

Allow thermal movement

Heating and cooling pipes expand and contract as operating temperatures change. Correctly positioned fixed points, guides and sliding supports allow this movement to be controlled and help limit unwanted loads on pipework and connected equipment.

Retain insulation continuity

A poorly designed support point can compress insulation or create a thermal bridge. Insulated pipe supports transfer the pipe load, maintain the required insulation thickness and support a continuous vapour barrier around cold services.

Use limited space better

Modular channel systems make it easier to route pipework, ductwork and other building services through congested areas. Adjustable, compatible components also allow installers to respond efficiently when site conditions differ from the original design.

Install with confidence

Walraven combines tested product systems with application guidance, calculations, CAD drawings, BIM content and parts lists. This helps project teams move from support design to installation with fewer uncertainties.

Applications for building installations 

Different HVAC services place varied demands on how they are supported. Walraven offers compatible solutions for heating, cooling, ventilation and water installations.

Heating pipework

Heating pipes undergo repeated expansion and contraction during operation. The support arrangement must carry the pipe load while directing movement and limiting stress on branches, valves and connected equipment.

Walraven clamps, channel systems, fixed points, guides and sliding components can be combined to create an organised and repeatable support arrangement.

Designed to help:

Accommodate thermal expansion and contraction
Create controlled fixed, guided and sliding points
Support pipework from walls, ceilings and floors
Simplify installation across changing site conditions

Air conditioning and cooling

Insulation continuity is particularly important on cold pipework. Gaps, compressed insulation or exposed metal at support points can create thermal bridges and increase the risk of surface condensation.

Walraven BISOFIX® insulated pipe supports carry the pipe load while integrating with the surrounding insulation system.

Designed to help:

Maintain insulation thickness at support points
Support a continuous, vapour-tight insulation finish
Reduce thermal bridging and condensation risk
Protect the performance of chilled-water installations

Ventilation services

Ventilation ducts, air-handling components and associated pipework often share crowded ceiling and plant-room spaces with other building services. Select supports that are adaptable, space-efficient and practical to assemble overhead.

Walraven channel systems, anchors and fixing accessories can be combined into suspended or wall-mounted support structures for ventilation and mixed-service installations.

Designed to help:

Support ventilation ducts and associated services
Coordinate several services on shared support structures
Keep inspection and maintenance routes accessible
Create neat, space-efficient installations

Hot and cold water

Water distribution systems require secure, durable support throughout the building. The design may also need to accommodate temperature-related movement, insulation and acoustic requirements.

Walraven pipe clamps, insulated supports, rails and anchors provide a compatible system for supporting hot- and cold-water services in residential, commercial and public buildings.
